One of the biggest thrills of spring is when the beautiful and acrobatic swifts return to the UK after a long and perilous journey from Africa. They tell us that summer is on its way soon and that all is well with the world.
The sad fact is that Ealing’s swifts, like swifts across the UK, are in serious decline. Swifts spend their winter in Africa and return to the UK in April with their lifelong partner and offspring to breed in the same area as last year. Swifts are used to living alongside humans, but modern building design and the refurbishment of old buildings have been depriving them of the nooks and crannies that they use for nesting sites.
The Saving Ealing’s Swiftsproject is to combat the decline of swift nesting sites. Ealing Wildlife Group is planning to erect 150 nest boxes to boost existing colonies of swifts and attract new colonies. The nest boxes will be sited on public buildings across the borough, with signage to tell the public about these wonderful birds. The project will boost biodiversity in our borough & engage local communities with the conservation of these birds.
The swifts will be returning in April and May 2022, and so we hope to have the swift boxes erected by March, in plenty of time to help protect and conserve this iconic species for future generations. Can you help by making a pledge to our fundraising effort? We need to raise £10,000 in total, including £5000 from our followers which will be matched by Future Ealing. Every little helps and you can pledge at www.spacehive.com/savingealingswifts. If you are not able to contribute, there are other ways you can help, by offering your time to support some of our work by volunteering.
Thank you all for your ongoing support and for making Ealing such a great place for wildlife!
“Conservation work involves the protection, preservation or restoration of nature and biodiversity, not a task one would immediately associate with Instagram or TikTok. However, more and more we are utilising social media platforms to share ideas and information, organise events and have conversations with one another regarding wildlife and the environment. It’s blending our very primal need to be one with nature with our newly evolved reliance on technology, and in most cases, it is working to the benefit of the natural world.
In the case of releasing endangered captive-bred harvest mice back in Ealing we have Instagram Stories to thank. No, really.
I have followed Dr Sean McCormack and Ealing Wildlife Group on social media for a while. I was inspired by the passion and innovation of both and drawn back each time on my phone by the community spirit and the sharing of wildlife photographs and information.
When Sean posted on his Instagram about a new project to return harvest mice back in a suitable habitat and monitor their population I paused my Netflix show, put my glass of red wine back on the coffee table and furiously began constructing my reply. I had to be involved.
I work as an Animal Keeper and Education Officer at a small zoo in South Lanarkshire, Scotland. We care for a very successful breeding group of harvest mice and had been on the look out for a while for a project to introduce our mice back into the wild, as we were reaching maximum capacity in their enclosure.
We had explored options in the past, but nothing seemed to work out or last. I wanted a project that Calderglen could fully get behind and believe in, and that gave our Scottish mice the best chance at surviving.
After talks with Sean I knew the area chosen for their release and the people involved offered the harvest mice the best chance at restoring a wild population in Ealing. A species that hasn’t been recorded there since the late 1970s. It was time for that to change.
After a couple of months of more conversations and planning with Sean the morning arrived for the long journey down to London. I plucked the fittest mice from the safety of their captivity, clinging unknowingly to their corkscrew hazel branch and silently wished each one good luck as I placed them into the travel box, awaiting a life of freedom only wild animals understand.
It’s not lost on me the control humans have over non-human species and even though in my heart I knew I was doing the right thing for the conservation of harvest mice, looking at each individual twitching face, I also battled with doubt if it was what they would want.
It may seem silly, after all how could a mouse possibly understand the concept of consent and the importance of its little life in the preservation of its entire species, but it certainly picked at my moral compass regardless.
It’s why I take so much comfort in Ealing Wildlife Group’s project because out of the many that have been reviewed by Calderglen this one surpassed expectation.
It was a lovely evening when I met with members and volunteers of Ealing Wildlife Group and I quickly felt I was with ‘my people’. Our enthusiasm and passion kept the chat flowing as the sun started to dip and the smiles and laughs just got wider and louder even after we stopped recording videos on our phones. Everyone was excited to be there, everyone wished for the success of the project, and everyone believed it was the right thing to do to give back to nature.
We let Calderglen’s mice go in thickets of grass and flowers, with a small shelter and some food left behind for a short-term resource if they should need it. I watched one particular brown and white fuzzy ball dart immediately from the travel box and wind its way gracefully into the foliage.
A bubble of emotion rose in my throat as I again wished it a silent good luck. As I uploaded the video to my Instagram with the caption ‘They’re free!’ and watched the mouse get lost behind stalks of green and fade from view, my doubts vanished. The harvest mice were home. “

We’re very excited to be partnering with Battersea Children’s Zoo and their sister zoo, New Forest Wildlife Park, both of which will be providing us with captive bred harvest mice to release in Ealing over the coming years. I recently visited Battersea and was astounded by their beautiful Harvest Mouse exhibit, which showcases just how busy (and adorable) these little mice are. Here’s what Head Keeper, Jamie Baker, has to say about the partnership:
“Battersea Park Children’s Zoo has always championed British native species. Alongside our conservation work with other BIAZA and EAZA facilities on European Endangered Species breeding programmes we have always worked to put our own native species at the forefront of our work. As one of most successful zoos working with the Scottish wildcat breeding programme, producing 5 kittens over the last couple of years, we also collaborate on reintroduction projects for native hedgehogs and of course, Eurasian harvest mice, which are increasingly threatened in Britain.
We currently have one of the largest harvest mouse exhibits in the country and actively breed mice at the zoo before transferring them to reintroduction projects up and down the country. Education is key in providing a future for our native species, so our dedicated harvest mouse barn is a great opportunity for our yearly 8500 school children to connect with these relatively unheard of creatures.
We are excited to have struck a new partnership with Ealing Wildlife Group and can’t wait to shine a light on their amazing work to restore wild places in London and reintroduce native species. Our curator Jason and head keepers Jamie and Charlotte had the pleasure of welcoming Sean to the zoo recently to discuss our joint passion for harvest mouse conservation and we look forward to providing captive bred harvest mice to Ealing Wildlife Group’s upcoming release projects. Joining forces to rewild some amazing habitats in West London.”
The team at Battersea and New Forest are also keen to come help us survey for harvest mice to monitor how well the reintroduction project is going over the coming years. There will also be opportunities for volunteers to help with this important work. Exciting times!
We’ve recently kicked off our ‘Rewilding Ealing’ initiative with the reintroduction of locally extinct and nationally threatened species, the diminutive Harvest Mouse. Also known by its scientific name of Micromys minutus, or the ‘minute micro mouse’, it’s the UK and Europe’s smallest rodent, and the only one with a prehensile tail designed to cling to the finest of grass stalks and vegetation as it climbs.
Last year we outlined the aims, preliminary survey work and preparations for the project in a live webinar, recording available to watch here:
We were thrilled with the reaction to our crowdfunding campaign to raise funds not only to source mice in large numbers for release but also allow us to buy equipment and housing for our very own captive breeding facility. We asked our community of wildlife fans to sponsor a mouse for £10 and reached our target within days. The crowdfunder, which is still open to donations to support our borough wide conservation efforts, can be found here:
We’ve partnered with Calderglen Zoo in East Kilbride near Glasgow who have been breeding Harvest Mice, and a few weeks ago delivered our very first mice to be released as well as to form the foundation of our own captive breeding colony.
And since the initial release we’ve had quite a bit of interest and coverage including BBC London and Scotland news. Check out the release and see these amazing little rodents being set free into the wild after a potential absence of 30-40 years from our borough here:
Group reintroduces the threatened Harvest Mouse back to London!
Harvest Mice are set to be released in a new location in London by a local community group in Ealing, West London – bringing the rodents back to the area for the first time in decades.
Harvest Mice are Britain and Europe’s smallest rodent, and, in recent decades, these miniature mammals have undergone rapid declines due to changes in land management nationwide. The mice live mainly in grassland areas and eat seeds, fruit and invertebrates and build their spherical nests high up in tall grasses.
Reinstating the harvest mouse population is important for a number of reasons but, most significantly, their presence in the Ealing area can support the wider food chain and will be a welcome addition for Ealing’s growing populations of birds of prey including Barn Owls, Kestrels and Little Owls.
Local community group, Ealing Wildlife Group (EWG) are behind the project. EWG are focussed on bringing nature back to urban areas and have spearheaded a number of other successful projects in the area including driving the increase in bird of prey species nesting in the borough.
In order to release the Harvest Mice, Ealing Wildlife Group (EWG) successfully crowdfunded their project to purchase hundreds of captive bred mice from one of the UK’s leading rewilding experts and set up small breeding colonies of their own. The plan is to release the mice into the wild over the next couple of years.
Sean McCormack, Chair of local conservation community Ealing Wildlife Group (EWG), believes that communities and councils can work together to create suitable space for nature, and the Harvest Mice reintroduction project is just the latest in a long line of projects being spearheaded by EWG. Dr McCormack said:
“After extensive surveying of likely locations in Ealing, we believe Harvest Mice are locally extinct here due to historic habitat loss and fragmentation. Over the last few years however, there has been an effort to manage some of Ealing’s green spaces more sympathetically for nature. What this has done has enabled several sites within the borough to now have habitats suited to the reintroduction of Harvest Mice.”
After holding a webinar with the local community to outline the details of the project, McCormack set up a crowdfunding page to help fund the reintroduction – asking funders to ‘sponsor’ a mouse for £10. The money raised will go to buying mice from a responsible breeder, one who supplies many rewilding projects with rare and threatened native wildlife, plus equipment for setting up some small breeding colonies of their own – enabling EWG to continue releasing mice into the wild in Ealing over the next couple of years.
EWG are also partnering with a number of conservation organisations already breeding Harvest Mice including Calderglen Zoo in East Kilbride near Glasgow, who have supplied the first cohort of mice to have been set free into the wild in Ealing.
EWG will also spend an extra £500 on Longworth live mammal traps, enabling the harmless monitoring of small mammal populations in Ealing. This monitoring will ensure the habitat management continues to be successful and that populations of the harvest mice, as well as other small mammals such as voles and shrews, can continue to thrive for years to come.
Fundraising has been incredibly successful and the £2,500 target was hit within days of set up however, if you would like to contribute to this exciting urban rewilding project, you can find the Harvest Mice Reintroduction page here.

About Dr Sean McCormack
Sean McCormack, vet and Chair of local conservation community Ealing Wildlife Group is passionate about nature and biodiversity. He has a large instagram following and offers content across a variety of topics (animal welfare, biodiversity and allotmenting). He also showcases some of EWG’s practical conservation projects on their highly subscribed YouTube channel. Sean hosts the popular podcast ‘Sean’s Wild Life’ talking to relevant experts and celebrity guests to explore topics in nature conservation, rewilding, sustainability and our connections to nature.
EWG is an inclusive community of locals interested in nature and wildlife in the Borough of Ealing and beyond. Set up in early 2016 by Sean McCormack, a vet and lifelong naturalist, the overall aim of the group is to build a community of like-minded individuals, who are passionate to learn more about nature and who see the value in actively conserving it. Since 2016 it has grown steadily in membership and secured funding for several community environmental projects. The main hub of activity and discussion remains the Facebook group, where members can truly appreciate the diversity of wildness on our doorstep through others’ observations and posts.
Back in 2018 EWG and the Council ranger team collaborated on a fundraising bid to erect owl nest boxes all over Ealing for Barn, Little and Tawny Owls, the three most common species found in and around London. Barn Owls were our main target species, as we knew the other two were already breeding here in relatively good numbers. But the Barn Owl situation was less clear. We’d spotted and had sightings reported of them hunting in various areas, but no confirmed breeding.
So we managed to secure £2000 from Tesco Bags of Help to try to help them become established. We bought about 18 nest boxes of various designs to attract all three species and later in 2019 got to putting them up all across the Borough in likely locations. And with the parks team, we set about changing some of the local grassland management to encourage more biodiverse rough grassland habitat, mown on a 3-4 year rotation to encourage voles, mice and shrews. Basically boosting our owls’ and other predators’ food supply! You can see more about the early stages of the project here:
Our 2020 owl breeding season kicked off with a promising start as trail cameras placed on several of our boxes revealed that they were being visited by owls, including some Barn Owls. Unfortunately, the box where we confirmed Barn Owls as regular visitors in January and February fell victim to theft and disturbance later that season. Some men with a ladder were reported to us looking suspicious. and alas our trail camera containing all of our footage was gone. We had left it well alone after our last check in February so as not to disturb the owls if they were breeding. But when we went back to check in May/June the camera and the owls were nowhere to be seen. A hazard of leaving wildlife cameras out in any location, but especially in the urban environment. All was not lost however, as a pair of Kestrels moved in and raised young in the same box. Not a target species, but very welcome nonetheless.
We believe a Little Owl pair attempted to breed in one of our boxes in 2020 but couldn’t confirm if they successfully fledged. Anyway, the pandemic and lockdown restrictions prevented us getting out to monitor and check our nest box success rates for much of the breeding season, but this project was always going to be a long game of providing nest sites, changing habitat dynamics and boosting prey availability. We were patiently impatient that the 2021 season would be better and yield success.
Below is some footage of various owl species visiting, and even scrapping for access to our nest boxes. This tells us that with such competition and defense of boxes, that natural nest sites suitable for owls are in short supply. It makes sense as old trees with large cavities are few and far between in urban environments in particular where human health and safety is a genuine concern to be balanced alongside nature conservation.
2021 saw lots of owl action at various boxes, with all three species investigating. One particularly feisty Little Owl pair commandeered a large Barn Owl box for themselves, fighting off Barn Owls and Tawnys that came to inspect it for their own uses as you can see here:
We’ve been out recently with local licensed bird ringer Phil Belman to check on our nest boxes under license and ring any chicks we found for ongoing population monitoring. And though we are a little disappointed to say we’ve not confirmed any Barn Owls breeding (although there is still one inaccessible box and camera left to check), we have had a great year for Little Owls with a total of 10 chicks from three of our boxes. We tend not to check Tawny Owl boxes too closely as they have a reputation for being aggressive at the nest site. We did find one very early Tawny chick that fledged from a natural nest site locally, you can see him/her in this video:
Hopefully next year the possibly young and inexperienced Barn Owls who have been prospecting for nest sites at our boxes will move in and raise their own chicks. We’ve increased our number of boxes in 2020-21 too, with some of our members kindly making and donating nest boxes to the cause. Thanks Peter Nolan, David Gordon Davy and the Sullivans for making some great boxes for us free of charge. And here’s hoping 2022 is a bumper year for Ealing owls!
In the meantime, enjoy some photos of the adorable Little Owl chicks we ringed recently. Thanks to BTO licensed bird ringer Phil Belman for collaborating with us on this important part of the project to monitor our owl populations and how habitat management is affecting them over time.
We have been busy behind the scenes scoping out the habitats, logistics and feasibility considerations for reintroducing Harvest Mice to Ealing. This tiny rodent species has declined significantly nationwide in recent decades, and we believe after much surveying in suitable habitats that it is locally extinct. For more context on Harvest Mice and the project you can watch our kick off meeting here:
As with any reintroduction project, there are ethical and practical procedures and guidelines to follow so as not to:
cause harm to the local ecosystem
cause welfare issues with the reintroduced species or others in the local environment
cause socio-economic harm or concerns
introduce disease into natural ecosystems
We have reviewed DEFRA’s newly released codes and guidance for reintroductions and other conservation translocations. And we feel we have satisfied the requirements as well as carried out the appropriate surveying and preparations needed to justify and carry out a successful reintroduction programme. We’ve also consulted with previous Harvest Mouse reintroduction project managers and rewilding experts who advised us that we have the suitable, sustainable and connected habitat to bring back this lost species again. More info on the codes and guidance can be found here:
So what’s next and where are our mice coming from? Well, we’ve teamed up with a zoo and country park in Scotland who maintain a large colony of harvest mice and want to collaborate with us on an in-situ reintroduction and conservation project for the species in their natural habitat. We’re also working with renowned rewilding advocate and expert, Derek Gow and his team, who are supplying us with captive bred mice for mass release and to start our own ongoing captive breeding programme.
And we cannot thank you, our supporters, enough for donating to fund the project by sponsoring a mouse (or many mice in some cases!). It’s a project which has obviously captured the public imagination, and it has also attracted some media attention (watch this space!). We hope to start releasing mice as early as July and September this year, and hope to have some of you along to see ‘your’ mice return to the wild. The crowdfunding was a great success, and is still open for donation to support ongoing costs of the project if you wish to sponsor a mouse for just £10.
Where we were in 2020, where we are now, and where we are going in 2021
It’s been awhile and circumstances have slowed everything down but things are still moving forward at Costons Lane!
The weather and Thames Water have delayed the pond building until we get the go ahead from TW and it dries out a bit, but we have been working on other aspects of the project! The contractor has lifted the gate (so it opens now!) and will be building the platform for our building and the paths in the front half. Once this work is complete and restrictions lift, we can have volunteer days again! Our first task will be create the wildlife garden. And once the platform is complete we can order our beautiful green roofed recycled shipping container and finally give Ealing wildlife Group a home of its own!
Of course the first priority of a nature reserve is to provide a place for nature to thrive and CLNR is no different. We had a bioblitz last summer, the first of many, to see what kind of plants and animals call it home. As expected most of what we found were insects and arachnids which is very good as the UK is catastrophically losing insect life! We had a few ladybirds, several species of tiny parasitic wasps, two kinds of grasshopper, leafhoppers, dock bugs, blue flea beetles, dragonflies, many different butterflies, bumblebees, honey bees, several spiders we don’t know what they are yet and a few wasp spiders which are always exciting! You can see the full gallery of critters below, the ones we know are named, if you think you can identify any of the others or think we may have got it wrong leave a comment below!
As for birds we saw and heard robins, starlings, house sparrows, wood pigeons, and a red kite and sparrowhawk over head! On different occasions we have also heard wrens, green finches, and black caps as well! No amphibians or reptiles yet, but creating the pond should help the amphibians and of course we plan on building habitat for slow worms and if we are lucky maybe even grass snakes! The mammals we found were grey squirrels (of course,) a curious fox, and a few pipistrelle and soprano pipistrelle bats. We were expecting more bats but again the pond will create food and should attract more, most we saw seemed to be on their way to the river where food is plentiful.
Throughout the summer and early autumn we had several volunteer days, while it was still allowed and safe to do so. The first one was the biggest, with 30 volunteers and the help of the Ealing Park Rangers we moved enormous amount of rubbish out to the entrance to be picked up later! The area was originally an allotment site (abandoned 20 years ago because of the constant flooding) so much of the rubbish was bits and pieces of old allotment detritus. Unfortunately, it was also used as a fly tip so we found toilets, shopping trolleys, old footballs, shoes, batteries, you name it! Park rangers Jon and James cleared a path around the site with a giant mowing machine and later it will properly mulched. Our second two volunteer days were mostly clearing brambles from the area we plan to turn into a meadow to replace the meadow that will be lost when we build the pond. We still found and moved a tonne of rubbish we even found a bathtub! Then the lockdowns came and the weather turned and volunteering stopped for the winter.
So where do we go from here? Anticipating the lockdown easing up in the spring, we will continue to have volunteer days, starting with the wildlife garden. And also exciting news, we have got two shipments of free trees from I Dig and the Woodland trust, so we will have to plan a planting scheme and get planting them out! Then working around the heavy works of pond building and path laying, we will build the bird hides and the pond dipping platform. I plan on setting up a spring bioblitz, as at Boles meadow I’d like to have a bioblitz in every season. After the large projects are complete, it will be different tasks, building and installing bird and bat boxes, different feeding stations, increasing the diversity of plants and micro habitats, and seeing how we could increase our connectivity to other green sites in the area. Later as the building is installed, we hope to build a deck around it to give us more space to teach, and have community events.
So that’s about it, progress is slower than we would like but not too bad considering the circumstances. As always, if you would like to volunteer, pop us am email at [email protected] and put volunteer in the subject heading and let us know what you would like to do. It may be a while until you hear anything back because of lockdown but hold tight and rest assured your help is very much wanted and appreciated! Hope to see you all in the spring!
As the growing season winds down, people are starting to tidy their gardens and prepare them for winter. For wildlife friendly gardens and gardeners however, things are a little different, it’s far less tidy, and far better for the wildlife! Here are 10 things a wildlife gardener can do to prepare the garden for winter that benefit both the garden and the wildlife.
1. Clean feeders, feed the birds!
It’s always important to keep your bird feeders as clean as possible and this time of year is a good time to do it as it the feeders will be very busy over the next few months! Then fill the feeders with fat balls, fat blocks, coconut shells filled with fat, fat pellets, fat filled with berries, mealworms, peanuts! Lots of fat! Don’t use the plastic nets though as birds can get caught in them with tragic consequences! (Also we don’t need more plastic) Don’t forget seeds and fruit, and I was today years old when I found out you can leave out cheese and bacon bits as well (probably go sparingly so you don’t attract too many rats!) A firm favourite with my birds are sunflowers seeds, I think just about everyone likes them, I get the shelled ones, waaaay less mess! Don’t get cheap seed mixes though, they are often made with cheap grains that are too big for anything other than pigeons to eat, I learned this the hard way!
2. Keep water available!
Keep small bowls of water on the ground and/or bird baths available as it’s just as important for wildlife to access water in the winter as at any time of the year. If you have a pond and should it ice over (not super likely in London but it could happen), melt a hole in the ice so the critters can get in and out and drink, and to make sure your pond doesn’t become oxygen starved. Use a pan filled with hot water to melt a hole, do not bang on the ice to break it as this sends out painful shockwaves that can hurt wildlife. (I’m imagining being inside a ringing bell, not a pleasant thought!)
3. Watch out for Hibernating Animals!
Check bonfire material for hibernating animals such as toads, hedgehogs, and frogs before lighting! (Better yet only build the bonfire when you are ready to light it, then nothing can get into it) Be careful turning compost as it’s warm and could be full of slow worms, grass snakes, toads, frogs and other lovely things you want in your garden!
4. Make homes for the animals!
Don’t bag up all your leaves, spread them on the flower beds, it’s good for your soil and it provides shelter for frogs, and insects, and gives Blackbirds and thrushes, and Violet Ground Beetles a place to forage for food. Leave some pots and piles of bricks laying around for newts and toads ( they like the greenhouse too so watch out for them if you are tidying, I have frogs in mine!) Make or buy some bug hotels for the leaf cutter bees and other insects such as lacewings and ladybirds, or just drill some holes in a log! Place clay roof tiles in the pond for the frogs and newts that may be overwintering in the pond.
5. Leave the Soil alone!
If you can help it, avoid digging your garden beds, as many spider eggs and insect larvae (especially moths) overwinter in the soil.
6 Plant some Winter Berries!
Shrubs that feed wildlife in winter are great for gardens because they also provide beautiful flowers in the spring and summer, lovely foliage in the Autumn and striking berries and stems in the winter! I wrote another post with a list of native berries here (such as hawthorn, rowan, guelder rose etc) but other good non-native garden shrubs for wildlife are Cotoneaster, Pyracantha, Barberry (Berberis), and Virginia Creeper (Parthenocissus quinquefolia) although be careful with the last one, it can get invasive if not carefully controlled!
7. Leave it Wild!
Avoiding trimming ivy and don’t cut hedges until at least March. Both provide much needed food and shelter for overwintering wildlife. Leave all the herbaceous plants untrimmed until early spring. Leave it messy! Many insects overwinter in hollow stems, ladybirds will all snuggle up on a stem for the winter and if there is one thing you really want in your garden, it’s ladybirds! When you do finally cut the stems down in spring, set them aside in stacks until May so the insects can emerge safely.
8. Clean Ponds!
Winter (Oct through January) is the best time to clean your pond as it is the time of lowest activity. However there are still active critters in there so be careful! Always stack the weeds and debris you clear from a pond on the edge for a few days so things can crawl out and back into the water. Having a little poke around and giving some of the dragonfly and damselfly nymphs, other invertebrates, newts, frogs, and snails a helping hand back into the water is nice too.
9 . Clean out Nest Boxes!
In late winter clean out the nest boxes for the upcoming spring nesting season. Also be aware that some birds will roost communally in nest boxes in the winter to stay warm, especially wrens and house sparrows so making sure they have nest boxes or roosting pouches in you garden in winter could be very beneficial!
10. Help the Butterflies!
There are five species of butterfly in the UK that hibernate in winter as adults, the brimstone, comma, peacock, small tortoiseshell and red admiral. Two of these, the Peacock and the Small Tortoiseshell usually overwinter in a shed or garage, and if you see them there, leave them be. Sometimes though they will try to hibernate in your house, which would be fine if it didn’t get so warm. When the butterflies get warm they wake up and think it’s spring, and that is not going to be a good time for the poor butterfly when it’s still winter and there is no food in sight. So if you find an awake and confused butterfly in your house, the Scottish Wildlife Trust suggests the following:
The best thing you can do if you see a butterfly flying about in your house in the middle of winter is to help it relocate to a cooler spot. Put it in a cardboard box for a while to calm it down and then leave it in your shed, garage or another suitable location. Somewhere cool and dry is ideal. Remember to set it free when spring arrives!
Laura Preston, Scottish Wildlife Trust
So there it is, ten ways to help make your garden a safe haven for wildlife this winter! You will be rewarded come spring with an abundance of helpful creatures to keep your garden ticking along as well as the knowledge that you are also helping them to survive and thrive when so many are in shocking rates of decline across the country. Gardens make up one of the largest green spaces in the UK so we can have a huge impact on the future of wildlife, one garden at a time!
In the dark cold days of winter, nothing is more cheery in the grey landscape than colourful winter berries dotting the hedgerows. However not only are they beautiful , they provide a vital food source for birds, insects, and mammals when little other food is available. All of the following berries can be found growing wild and in gardens in Ealing. They are a great addition to any garden/greenspace to help the wildlife through the winter! (I realise that several of these are technically not berries, but I will refer to them as such for the sake of convenience)
Hawthorn (Crataegus monogyna)
You can find hawthorn pretty much everywhere in the Borough, on the sides of the A40, up on Horsenden Hill, the Bunny Park, everywhere. Found in hedgerows the fruits are called Haws and are eaten by loads of migrating birds such as Redwings, Waxwings and Fieldfares. Our natives such as Blackbirds, Greenfinches, Yellowhammers, Chaffinches, Hawfinches, Starlings and many other birds enjoy them too!
Rowan (Sorbus aucuparia)
Rowan is another winter bird favourite, including Mistle Thrush, Redwing, Song Thrush, Blackcap, Fieldfare and Waxwing. This feeds more than just birds, caterpillars of the apple fruit moth feed on the berries as well!
Dog rose (Rosa canina)
These beautiful native hedgerow roses turn into the bright red hips that feed birds such as Thrushes, Blackbirds, Redwing, Fieldfare and Waxwings, which then disperse the seeds in their droppings, and some birds like finches actually eat the seeds!
Blackthorn (Prunus spinosa)
The beautiful plum like drupes of the Blackthorn (called sloes) provide insects, mammals, and larger birds like the thrushes and hawfinches a lovely midwinter feast. Humans also use them for making flavoured gin!
Spindle (Euonymus europaeus)
House Sparrows, Robins, Blackbirds, Song Thrushes, various Tits, and Starlings, and even mice and foxes eat the berries of the spindle. (It’s poisonous to humans though!). I haven’t seen a lot of spindle in Ealing, but I might just not be looking in the right places though as it’s a sign of ancient woodland. I will keep an eye out for it in our local bits of woodland such as Long Wood, Fox Wood, Horsenden Wood, and Perivale wood. Please let us know in the comments if you spot any out and about!
Holly (Ilex aquifolium)
Most birds leave these until later in the winter; they eat certain berries at certain times in the winter to ensure they have enough to last until spring. Mistle Thrushes, Song Thrushes, Blackbirds, Fieldfares and Redwings all eat the berries. However the Mistle Thrushes don’t mess around, they will aggressively guard their berries to prevent all the other birds from getting any! Small mammals like wood mice and dormice also enjoy them.
Ivy (Hedera helix)
This is another high fat, calorie dense berry that the birds leave until late winter when the other berries have dwindled and the ground is still too hard to forage for worms and insects and nothing else is growing. Some of the bird species that enjoy Ivy berries are Thrushes, Blackcaps, Bullfinches, Wood Pigeons, Blackbirds, Doves, Warblers, and Jays. And despite popular belief Ivy does not kill trees!
Guelder rose (Viburnum opulus)
Another ancient woodland indicator, the red berries are an important food source for birds, including Bullfinches and Mistle Thrushes. Far from ancient woodland however, the berries are a favourite food of Waxwings coming from Scandinavia who can often be seen scarfing them down in car parks! If anyone knows of a local guelder rose landscaped car park, please comment below so we can all potentially see some Waxwings this winter!
Mistletoe (Viscum album)
I almost didn’t include mistletoe because it is relatively scarce in Ealing (and London in general) but can you talk about winter berries and not mention mistletoe? Mistletoe doesn’t grow as a separate shrub, they are parasites and derive most of their nutrients from their host trees. They particularly like Hawthorn, Lime, Poplar, Sycamore, Ash, and in the UK their favourite is Apple trees. They are hemi parasitical however so they do also photosynthesize. Blackcaps love mistletoe, they eat the pith but wipe the sticky seeds off their bills and onto the tree branches, helping the mistletoe find new hosts trees. Mistle Thrushes (unsurprisingly) also enjoy mistletoe berries.
This Friday Dec 4th at 8pm, join Sean McCormack for an online discussion about a potential reintroduction project of Harvest Mice in Ealing. We’ll be exploring whether we have Europe’s smallest rodent species in the Borough, how we might find out with some help from our members, whether we still have suitable habitat and why such a project might be beneficial to people and biodiversity.
This is hopefully the first in a series of talks exploring rewilding and nature conservation in Ealing.
There are 100 spaces; first come, first served. Please do join live so you can take part in the Q&A afterwards. A recording of the session will be posted after for those who missed the live event.
The meeting will be on Zoom, details as follows:
