Bluetits hatching

My weekend was made when I turned on the TV and saw the bluetits in our camera nest box were hatching.

The newly hatched chicks look so vulnerable, it’s amazing any ever survive to fledge. Their tiny necks look much to weak to support their heads, yet when a parent bird enters with an insect, the chicks manage to fling their heads back and open their beaks.

At first the chicks were silent, floppy little things. It’s hard to count how many there are as it’s not obvious what bits belong to which chick. By the end of Sunday, our best guess was that five chicks had hatched, and three eggs remained.

It’s wonderful to see chicks in the camera nest box. Last year a pair of bluetits started building a nest in it, but gave up. When we put the camera back in this February, we couldn’t remember if we had cleaned the box out last autumn, or if the nesting material in there was last year’s. It took a while to be sure that bluetits were adding to what was in there.

A few years ago we had two successful house sparrow broods, but nesting materials blocked the camera, so we couldn’t see what was going on.

The only previous time bluetits have hatched in the box, none of them survived to fledge, as one of the adults went missing, and the lone parent wasn’t able to keep up the supply of 100 caterpillars a day that each chick needs. I hope this year’s brood will be more successful.

It’s a privilege to be able to witness such a special moment.

Dormouse box cleaning 2017

The dormousing year always starts with cleaning out the boxes, and doing any maintenance or replacements needed, ready for when the dormice belatedly emerge from hibernation. Often it’s not the most pleasant of tasks – March can be chilly, and getting rid of manky woodmice nests is never particularly pleasant. This year we were lucky – the weather was pleasant, and the boxes weren’t in too bad condition.

My site is still qutie new, and relatively unscathed by squirrels (who, at some sites, get through large numbers of boxes each year, targeting the glue that holds the layers together of the marine plywood we use). This means there wasn’t too much maintenance to do.

We did have a few old dormice nests to remove. Whereas we’d normally leave the old nests on the ground, this time we bagged them up carefully – I can’t tell you why at the moment, but watch this space… There were also a few beautifully mossy old wren’s nests to remove.

None of the boxes were occupied yet, but hopefully with the lovely weather we’ve been having we might find some dormice in our April check.

It was a relief to be back out in the woods, after the winter break. I know nothing stops me going for walks in the woods in winter, but it’s so nice to be back in the surveying season again.

 

Horay for hedgehogs

I’m not the only one emerging from hibernation at the moment. A couple of days ago we finally saw our first hedgehog of the year. It’s been a long time coming, as we’ve been finding plenty of ‘signs’ of hedgehogs for a few weeks. 

We’ve been leaving out food for them, but whereas in previous years we could leave the bowl in the open, I think we need to build a hedgehog feeding station to keep out the neighbours’ kittens this year. 

It’s so nice to see the hedgehogs again. I hope the dormice will follow suit for our April box check. 

How to make an insulated bird bath

Birds need water to drink all year round. Our mini pond and bird bath do the trick most of the year, but during really cold spells they can get frozen solid, leaving the birdies thirsty. To tackle this, I decided to raid the garage for bits and pieces to make an insulated watering hole for birds.

What I used

Materials needed for the insulated bird bath

Tools needed to make insulated bird bath: glue gun, scissors, knife
Tools needed to make insulated bird bath
  • A polystyrene box (we used to use it to keep milk cool)
  • A strong black bin bag
  • A glue gun and sticky tape
  • A cold-proof bowl

How I made it

  1. I cut a hole in the lid of the polystyrene box, so the birds can get at the water without the water lising too much heat. I had forgotten how much mess cutting polystyrene makes – I was covered in white flecks which static made difficult to get rid of.
  2. Polystyrene isn’t waterproof or easy to wipe clean, so I covered the outside of the box and lid with black plastic from an opened out, heavy duty bin bag (making sure to leave the hole free). In addition to waterproofing and making the box easier to clean, the black colour will hopefully mean it warms up quicker when there is a bit of sunshine. I used a glue gun to attach the plastic to the polystyrene (until the glue ran out and I had to resort to tape).

  3. I put the cold-proof bowl in the box, to test how it fitted. I wanted it to come right up to the lid, so the birds could easily reach the water. I ended up having to create a small hollow in the bottom of the box so that lid could fit on when the bowl was in place. This made even more mess, turning me into a snowman. I then filled the gap round the edge of the bowl and the box with more polystyrene.

  4. I put the box in place (somewhere where it’ll get the sun, not too close to where cats could hide) and filled the bowl with water.

Did it work?

Well, on frosty mornings when the birdbath was frozen solid, and there were inches of ice on the pond, there was only a sliver of ice on the insulated bird bath that could be easily broken or removed.

I set up my trail camera for a couple of days to see if anything used it. While a song thrush and wren came tantalisingly close, the only animals that I actually saw drinking from it were cats. But lots of cats, lots of times. I have successfully created an insulated cat bowl. Not quite what I was aiming for, but maybe the birds will get used to it.

Modifications

One essential modification is to secure the lid in some way, to stop it being blown off. The stone I used wasn’t up to high winds, so I think tying it on with string would be better.

Dormouse activity in my site in 2016

I have been in partial hibernation this last couple of months, hence the lack of blog posts. But I have managed to do somethings, one of which is sift through my dormouse data from last year. I’ve made a little animation showing how dormice and other animals have used the boxes at my monitoring site over the last couple of years.

 

It’s great to see dormice making use of the boxes we put up in 2015. Hopefully it means this year they’ll start making use of the boxes we put up at the start of 2016.

Riversearch December 2016: jeweled birds

The day was overcast, and the trees lining the river were bare, looking almost desolate. As soon as I got down to the river for my Riversearch survey on the final day of 2016, I felt convinced that I would see a kingfisher.

The river level was quite low, and relatively clear for a change. No signs of pollution. My winter surveys are always the most thorough. The impenetrable barricade of nettles and brambles had died back enough for me to get much closer to the river than normal.

As far as the survey goes, there was little to report (which is good, but not interesting). I was rewarded for tearing myself away from the fireside by a glimpse of a kingfisher, the most spectacular of British birds. But that wasn’t all. As I retraced my steps, back to the car, I spotted my first ever goldcrest. I was very excited about this, as I have long wanted to see one.

As though the kingfisher and goldcrest hadn’t provided enough colour to make up for the dullness of the day, a pair of bright green ring-necked parakeets also made a show.

It was as though nature was reminding me that although 2016 may have felt pretty bleak, there were bright spots in it. As I start 2017, uncertain what it will bring,  I will look out for beauty.

Looking back at 2016

I’m looking forward to shaking the dust of 2016 from my sandals. But it hasn’t all been bad. Here are my highlights and lowlights from the year.

Highlights

I find January pretty tough – I’m not a fan of cold, and the lack of light gets me down. So a fun day out at the British Wildlife Centre with my fellow members of Surrey Dormouse Group was a welcome relief.

I love spring, and seeing the bluetits start to build a nest in my camera nest box meant the return home each day was exciting – what’s happened today?!

My Wild Garden 2016 challenge kept me busy over the year, as each month I tried to make my garden better for wildlife. For the first time this year I fed live mealworms to the birds – it was great seeing how well this went down with them, and something I’ll do again in 2017. We also installed an insect house, and it was great watching the bees move in. Perhaps my favourite Wild Garden activity of the year was creating the Bog Garden – lots of digging involved, but worth it. I’m looking forward to seeing how it does this year, now the plants have had a chance to bed in and grow.

As always, it’s a delight to watch hedgehogs in the garden, and even more exciting (and entertaining) to watch their courtship.

Dr C gave me a great new toy – a macro lens, and I’ve enjoyed experimenting with that over the year. The Macrophotography course I did with Adrian Davies was particularly helpful. Some of the images I took that day even featured in my 2017 calendar!

It’s been a good year for my dormouse site. In one box check we had 9 dormice (including 7 youngsters crammed into one box!), and we’ve now had dormouse activity in every part of the site, which is great news.

And it’s great that the Paris Agreement on Climate Change has now come into force. On a smaller scale, it’s lovely to hear that the beavers on the River Otter are breeding.

Lowlights

Work has been very tough this year (particularly in the first half of the year), so this blog has taken a bit of a back seat for a while. It’s frustrating, as I’ve loads of things I wanted to tell you about, and lots of photos and videos that need editing.

It’s not been a great year for my garden birds – the Big Garden Birdwatch in January, when we saw only one bird. The bluetits that started to build their nest in the camera nest box soon abandoned it. And when I looked at the data over the year from June 2015 to May 2016, it confirmed that we’ve had far fewer birds than normal.

The referendum result was staggering, and, to me, hugely disappointing. It’s still not clear how it will affect many things, including our laws for protecting wildlife and the environment. The whole campaign was a bit of a disaster – even those campaigning for remain failed to make a case on the positive things that EU membership has brought this country, including cleaner rivers, beaches and air, and protection for species like dormice. One thing is clear: we need make sure whatever happens next does not damage this protection.

2016 has seen a lot of beloved public figures die. Among them, perhaps the most famous tiger in the world: Machli, the lady of the lake. I was lucky enough to see her in the wild, back in 2006. She has had a long life for a tiger, and brought up many youngsters that will continue her legacy. But it’s still sad to think she is no longer ruling the temples and lakes of Ranthambore.

Let’s hope next year brings peace, reconciliation and restoration between people, and between humans and nature.

In which I moan about light pollution on the darkest day of the year

Today’s the shortest day of the year, so it may seem churlish to spend it complaining about light. But don’t get me wrong – it’s not sunlight I have a problem with. I can vaguely remember what it’s like, and I’m keen to renew the acquaintance. It’s light pollution that I want to talk about today.

It’s obvious how water pollution can harm wildlife – the dramatic decline of the otter in the mid 20th century is a well known example. And we’re hearing more about the health effects air pollution has for humans (and presumably wildlife are affected too). But there’s less awareness of the problem of light pollution.

Last week there was a story on the BBC website about how robins’ behaviour is affected by light pollution. A study by Southampton University found that robins that lived closer to lit paths and noisy roads were much lower down this dominance hierarchy – the birds in these territories displayed less aggressively.

Robins aren’t the only creatures affected by light pollution. Other birds, reptiles, amphibians, moths and bats are also affected negatively. But some species can adapt to make the most of it, like the common redshank, getting longer to feed because of artificial lights.

Another disadvantage of light pollution is that it stops us seeing so many stars. Where I live, in a street-lit town, I’m never going to see the Milky Way. On holidays to more remote, darker places, the stars at night take my breath away.

Light pollution is a subject that’s too close to home for me. My bedroom overlooks a recently refurbished office building that’s floodlit throughout the night, meaning that, despite the blackout lining of my curtains, my bedroom never properly gets dark.

In some places things are being done to reduce light pollution. The funding cuts for councils means many are now looking to save money (and reduce carbon emissions) by turning off street lighting in residential roads late at night. In fact, my council are introducing this to the town I live in next month. My road is a major traffic route, so the lights will stay on. But other, quieter roads, will have their lights turned off between midnight and 5am in the morning. Hopefully this will benefit at least some of the local wildlife and residents.

As for me, I’m looking forward to a trip west, where night will be dark, and, if the skies are clear, I’ll be able to see the Milky Way.

A bit of hope in 2016

2016 has been short on good news, and I have been a bit despondent of late. Luckily this little fellow arrived in the post on Friday, to remind me that not everything has been a disaster this year.  I’ve called him (unoriginally)  Justin.

To recap: a while back beavers were found on the River Otter in Devon – the first wild beavers in England for centuries. At first the government wanted to get rid of them, citing the chance they may harbour parasites as the reason. But Devon Wildlife Trust, with the support of local landowners and residents,  persuaded the government to let them monitor the beavers and the effect they have in a trial, before making any final decisions. The beavers were trapped, had health checks, and re-released back on the River Otter.

This year Devon Wildlife Trust have been crowd funding to cover the costs of the trial. I donated a while back, and Justin is my reward. The timing of his arrival is good, as I had just found out that two pairs of beavers have successfully bred on the River Otter this year, one having two kits, and the other five.

I’m intrigued to see how the trial goes. Beavers, like humans, shape the landscape they live in. Chopping down trees, creating lakes and changing the course of rivers. I got to see some of the effect they were having when I visited the River Otter. There’s evidence that the changes beavers make may benefit other species, and reduce flooding downstream. But can we learn to live with a species that can make such dramatic changes in a short time?

If the trial is successful, it will give me hope that native species we have driven to the brink of extinction may, one day, make a comeback. If Devon Wildlife Trust can’t raise sufficient funds to cover the cost of the trial to 2020, the beavers will have to be rehomed in captivity. I hope it succeeds, and one day I will see a beaver in the wild. If you’d like more info, or to donate to the crowd funding appeal, visit SupportDevonsBeavers.org
