Swifts Take Up Residence

Two years ago, the Lewisham Swifts group enlisted the help of the Forest Hill Fire Brigade to install swift nest boxes on the side of a block of flats in Wynell Road, SE23. Swifts are migratory birds and visit the UK from May to July to breed and fledge their young, before returning to Africa for the rest of the year. As swifts only nest in buildings, providing nest boxes is vital in trying to reverse their declining numbers. 

This year a local swift spotter was very excited to see two of the new nest boxes in use by swifts. It is not known whether the new residents were breeding pairs, but now that swifts have found the boxes it is highly likely they will produce new generations of swifts over the coming years. Look out for them when they return in May!

Slow-worms: They’re Not Slow and They’re Not Worms!

Have you ever heard someone explain that a slow-worm is a snake, and a slow-moving snake at that? Or even a large worm? These myths are wrong, although a slow-worm does look rather snake-like at first glance.

They are, in fact, legless lizards that can shed their tails and blink with their eyelids, just like other lizards. They are smaller than snakes — around 30cm long — with a shiny, smooth grey skin, and they can live for up to 20 years!

Slow-worms are the most common reptiles to be found in London, and can be found in nature-reserves in south-east London (including along our railway line) where they seek out invertebrates to eat. 

They spend the winter hibernating in underground tunnels and log-piles until they emerge in March. Like other lizards, they give birth to live young. They like curling up in compost heaps and in warm spaces under corrugated metal, but if you find them they will wriggle away quickly. Cats will catch slow-worms and kill them, so be aware if you have a cat!

Slow-worms are a protected species; if you find any in your garden Lewisham Biodiversity Partnership would be happy to know. When waste ground comes up for redevelopment, it is important to establish whether slow-worms live there in order to ensure they are protected and new homes found for them.

You can help slow-worms by leaving log piles in underused areas of your garden for them to hibernate in through the winter.

How to be a Curious Entomologist

Insects are everywhere. They are so many, and so varied — fascinating, beautiful, mysterious, bizarre. Through their mind-boggling biodiversity they offer us a window into the ecological complexity of life on Earth, and give us a powerful insight of the workings of the natural world. But their small size means they can easily be overlooked or ignored. However it doesn’t take much specialist equipment to have a closer look.

Using simple methods and materials provided, this 1-day workshop will look at techniques to find and observe a wide variety of different insects, then how to preserve sample specimens for examination under the microscope.

In the morning, we’ll tour the reserve, finding and discussing the many different insect groups — looking at their structure, behaviour, life histories, and some easy identification pointers. In the afternoon, during the laboratory session, there will be the opportunity to look at some in more detail, and consider how studying insects can contribute to our understanding of nature, and the contribution it can make through citizen science.

Curious? Why curious? Entomologists might, at first, seem a bit eccentric, but they pursue their study of the natural world with a passion fuelled by curiosity.

Richard Jones is an acclaimed expert entomologist, a fellow of the Royal Entomological Society and a former President of the British Entomological and Natural History Society. He writes regularly for BBC Wildlife, Countryfile, Gardeners’ World and Sunday Times. He has written several books on insects, including Extreme Insects, The Little Book of Nits, House Guests — House Pests, and Call of Nature — The Secret Life of Dung.

Horniman announces new Butterfly House attraction

The Horniman Museum and Gardens will open a Butterfly House in summer 2017, it announced today, following a successful planning application to Lewisham Council.

The new attraction will offer visitors an immersive experience, in a specially-planted indoor garden that will be home to a colourful range of free-flying, exotic butterfly species. The Butterfly House complements the Horniman’s current Living Collections, including alpacas, jellyfish and bees in its Animal Walk, Aquarium and Nature Base.

Victoria Pinnington, Director of Communications and Income Generation at the Horniman, says: ‘We’re thrilled to receive planning permission to create this wonderful new experience for our visitors. Butterflies are beautiful and fascinating creatures which play an important role in ecosystems around the world, and we can’t wait for our visitors to enjoy and learn about them close up. The Butterfly House will be an additional attraction in an underused part of the Gardens, making a day at the Horniman even more memorable.’

Work will begin with the demolition of an existing, unused building to make way for the glasshouse and surrounding landscaping. Tickets to the Butterfly House will go on sale later in the year, in advance of the summer opening. Horniman Members will enjoy free, unlimited visits.

See www.horniman.ac.uk for more information.

Devonshire Road Nature Reserve Open Day - 20th July

Be Nice to Nettles

Wildside – our regular look at the non-human residents of SE23

Next time you're tidying up the garden, spare a thought for the humble nettle. It may be a weed with an unpleasant sting, but it's a vital part of our ecosystem which is why it's actively encouraged at the Devonshire Road Nature Reserve.

Some of our favourite butterflies - Comma, Red Admiral, Peacock and Small Tortoiseshell - and several moths use the nettle as food for their larvae.

Nettles are the only British plant with true stinging cells formed of silica-rich "hairs" which fracture on contact with your skin. They then release a complex, chemical toxin. There's a very good evolutionary reason for this sophisticated defence mechanism; young nettle leafs are highly nutritious and need to protect themselves from hungry grazers.

But, if you're prepared to take a few precautions, nettles are very edible and, of course, they don't sting once they're boiled. In fact, the leaves are rich in iron and calcium. Nettle pudding was recently claimed to be Britain's oldest recipe dating from 6000 BC.

Traditionally, nettles have mainly been used in soups in springtime although nettle risotto is also very good (NB - nettles can cause indigestion in some people and you should only use the young leaves).

These days, there is interest in the nettles' pharmacological properties and there is research currently into the use of nettles as an anti-inflammatory in the treatment of arthritis.

National Be Nice to Nettles Week takes place every year in May so check out www.nettles.org.uk for details. And if your appetite for stinging nettles has been whetted, there is a pub in Dorset (The Bottle Inn) which runs an annual World Nettle Eating Competition which this year takes place on June 21st.

Garthorne Road Nature Reserve

10th May was a guided tour of Garthorne Road Nature Reserve. Below are a few photos from the area that is not normally open to the public.


Bitter Vetchling. A plant in the pea family which is rare in London. This is possibly the only site where they are found in Inner London.

Jersey Tiger Moths

Forget the Island of Rhodes and its famous Tiger Moths. You can see them right here in Forest Hill! The stunning Jersey Tiger Moth has, for slightly mysterious reasons, started breeding in the Devonshire Road Nature Reserve and is the only inland colony of the species in Britain. The other colonies are in the Channel Islands and on the South Coast.

They have black and white striped forewings and orange hindwings, decorated with black spots. And, unlike most moths, they go about their business during the day so there are plenty of opportunities to spot them.

They were first seen in small numbers at the Nature Reserve in 2004. But this summer, there have been numerous sightings around SE23.

It’s thought that a female tiger moth discovered the Nature Reserve in 2003. And, like so many of us who found our way accidentally to Forest Hill, decided to make it her home. And breed…

Horniman goes Batty

Tuesday 28th August 9pm-10pm is the Horniman Bat safari. Limited places are available for this chance to see bats in Sydenham Hill Woods.

Admittedly the photo here comes from my honeymoon in Dominica and is almost certainly not a species that would be seen in London, but amazingly bats do live in this corner of London.

To book a place on the safari contact the Horniman museum on 020 8699 1872 ext 129.

There be dragons!

Wildside – our regular look at the non-human residents of SE23

With names like Ruddy Darter and Broad-bodied Chaser to inspire the imagination, Dragonflies are every bit as exciting as their fire-breathing counterparts. And, unlike the fire-breathing variety (rarely spotted in SE23 since the arrival of fried chicken outlets and nail parlours), dragonflies are on show in Forest Hill – if you know where to look.

These beautiful insects have been around for more than 300 million years – that’s 55 million years longer than the dinosaurs - although back then they could have a wingspan of up to one metre.

Like so much of our wildlife, their existence depends on streams and ponds. The dragonfly’s larvae live in water for as long as 7 years before emerging. So, as our ponds disappear and streams are diverted underground, dragonflies have fewer places to breed and their numbers dwindle.

There aren’t many big ponds in Lewisham so, again, the Devonshire Road Nature Reserve is a vital haven. Azure & Large Red Damselflies, Southern Hawker, Black-tailed Skimmer, Broad-bodied Chaser and Common Darter have all been recorded in the ponds there in recent years.

Now is the perfect time of year to observe their incredible ability to fly forwards, backwards and sideways. Dragonflies love the sun so a warm day between late morning and early afternoon is the best time to see them.

The British Dragonfly Society is currently running a survey on where the Broad-Bodied Chaser lives. The male has a pale blue coloured abdomen and the female a brown abdomen. Both have dark brown triangular patches at the base of all four wings. To take part in the survey go online at www.brc.ac.uk

The Not So Common Toad

The Wildside - A regular look at the non human residents of SE23

The Common Toad used to be really common in SE23 twenty or thirty years ago. But, as so often, loss of habitat has meant a serious decline. In London as a whole, 90% of natural ponds have disappeared and this is disastrous for toads who aren’t good at colonising new areas.

Toads aren’t impressed with your average garden pond, so beloved of frogs and newts. A toad is looking for something altogether bigger and deeper. This is where the Devonshire Road Nature Reserve has been so successful. About 7 years ago, they created a large, deep pond and acquired toad spawn from Catford. Now, there is a very healthy toad colony there, which returns every March to breed.

Once established in a pond they like, toads usually do well. There aren’t many creatures that’ll attempt to eat even toad tadpoles. They’re very poisonous! Unlike frogs, toads spend most of their lives on land; they only use the water for breeding. And they have excellent homing skills, always returning to the pond in which they were born. So on warm, damp nights in Spring, Forest Hill toads will make the long, dangerous journey back to their breeding pond on Devonshire Road. Many won’t make it.

So how do you tell the difference between a toad and a frog? The most obvious difference is their skin. Frogs have moist, smooth skin. Toads have drier, bumpier skin, often brownish. Frog spawn forms large clumps, whereas toad spawn forms long ropes.

George Orwell was fascinated by the Common Toad and in 1946 wrote an essay in which he said watching them return to their breeding ponds was one of the things he loved best about spring. He felt reassured by the fact that you could still enjoy this sight in London even though "atom bombs are piling up in the factories and the police are prowling through the cities." So if you’d like to see the creatures that inspired Orwell, do visit the Devonshire Road Nature reserve at its next open day on 25th March or with the Forest Hill Society on 15th April. They may not fire up your political fervour but, if you’re lucky, they’ll give you a true sense of Springtime.
