The Ups and Downs of May

I would like to introduce you to a handsome friend of mine:

He is one of the pair of foxes who are waiting each evening for me as I put out some peanuts. A fortnight ago I finished treating them both for mange with a six-week course of arsen sulphur sprinkled onto sandwiches.

Here he is on 29th March:

And how completely and utterly pleasing it is to see him now:

The vixen’s mange was a lot worse than his but she is also much shyer and I have not been able to have a good look at her recently. However, as far as I can tell, she hasn’t deteriorated further in the last few weeks so I am hoping that she too is getting better. It is especially important to have been able to help them because they have cubs this spring.

Sadly this is not how I wanted to see my first fox cub of the year, lying cold and stiff in the meadows one morning with no obvious sign of what the problem was:

From its location in the meadows I think that this cub was from a different fox family to the mangey pair

The badgers are also waiting out in the open for the peanuts at the moment, but only when they don’t realise that I’ve arrived. As soon as they get any indication that I am there with them, they shoot away into the undergrowth:

It’s good to be able to get photos of them on my camera though.

On Friday evening we met up with a couple of fellow volunteer wildlife team members and attempted to do a bat survey of Walmer Castle grounds:

We certainly heard a lot of bats on our Magenta bat detectors and saw quite a few too, especially over the Queen Mother’s pond, but we struggled to identify individual species with our basic equipment. There were a good many bats of several species feeding in the castle grounds but we currently cannot say more than that!

But the highlight of the evening was not bat-related at all. Dave spotted a tawny owl nest with two fluffy chicks in a tree hole:

We got home at around 10pm and one last check of the swift box cameras before bed revealed that a swift had returned and was spending the night in the box:

However, the swift then left the box and has not yet returned. It was just a single parent that successfully reared two chicks to fledging in this box last summer, so maybe this bird has now had to go off to find a new partner. It will be interesting to see how our infant swift colony does this year, but it doesn’t seem to be getting off to a very strong start.

Elsewhere in the meadows, it is always good to see a kestrel:

A male kestrel has been hunting over the meadows this week, and he may well be trying to catch enough prey to feed both himself and some chicks

And broad-bodied chaser dragonflies are now on the wing:

We have actually had a bit of a batty week because there was a nice photo of a brown long-eared bat over in the wood:

This bat is flying towards the owl box and just look at the length of those ears!

Following the successful ringing of four tawny owl chicks in that same owl box last week, the young birds have now begun to appear on the camera:

When John removed the chicks from the box last week in order to ring them, he took a photo of the inside of the box. We had completely cleared this box out in mid February, but there has been a lot going on in there since then. The floor certainly tells that story:

A dead rodent has been cached and can be seen in the bottom right of the photo

The adult owls have been working really hard keeping their four chicks so well fed and deserve a bit of a rest and a drink by this shallow pool:

I don’t know where the buzzards are nesting this year – certainly not in our wood, but there is a large area of woodland in the vicinity with substantial mature trees that would suit them:

It was again a group of four of us that went round the dormouse boxes for May’s monitoring tour. John the bird ringer is interested in all the blue tit chicks that are being reared in both the dormice boxes and the bird boxes in the wood this spring. He is trying to ring as many of them as he can and then, when he puts his nets up later on in the year, he will be curious to see what percentage of the young blue tits he catches have fledged from the boxes.

Fourteen of the thirty boxes have had blue tits nesting in them this spring. Of these, three of the nests have failed:

John’s photo of a clutch of cold blue tit eggs in an abandoned nest in box 27. Did the parents perhaps get caught by a sparrowhawk?

This time four of the boxes contained young blue tits of the right size and he ringed thirty-nine chicks.

We also found eleven dormice on this month’s tour:

All the dormice photos are Clare’s

The highlight was definitely box 12 which contained three torpid dormice all cuddled in together:

Very sweet indeed.

I was in Maidenhead for a few days recently, and have a lovely routine when there of visiting Spade Oak nature reserve near Marlow with a friend to see what’s about. This time we saw several families of Canada geese. The posture of the adult geese when swimming with their chicks was interesting:

Canada geese often lower their necks and flatten their bodies against the water when swimming with their chicks and apparently this behaviour is called either ‘alligatoring’ or ‘stealth mode’.

It is suggested that it is both to look aggressive, warning potential predators to stay away, and perhaps also as camouflage to try to avoid attention whilst moving their goslings across the water – although I do not find this second explanation very convincing.

It has been a busy few weeks and I see that we are already nearly half way through May. Whilst every month has something to offer, it is May in particular when I would like to slow time down and fully savour every day. But there are still over two weeks of it to go and I will try to make the most of them…

Tawny Time

Something rather special has been going on in the wood this spring because a pair of tawny owls have chosen to nest in one of the owl boxes:

There is a camera rigged up to get close views of this box and this can be seen towards the bottom right of the photo

For several weeks now the male owl has been bringing prey to the box by night. The incoming rodents are mostly carried in the bird’s beak, leaving his feet free to land on the box:

Although sometimes he carries them in his talons instead:

Whilst the two rodents above are mice, the photos below are of a vole and a rat that are also being caught:

And no doubt dormice as well but it’s hard to tell in the dark. It is asking a lot of the male to catch enough prey to feed his entire family.

These night time arrivals were going on throughout the 28-30 days that the female was incubating the eggs, and are carrying on still to feed both the chicks and the female since she continues to spend much time in the box. This week, though, there has been a big change in behaviour because she is now sitting for long periods in the entrance to the box. Mostly awake…

..but sometimes asleep:

Her eyes are the deep, black pools of a nocturnal animal:

I have been reporting what has been going on at the box to John, the bird ringer, who will be acting under licence to ring the chicks. He has also taken advice from experts who regularly ring tawny owls here in East Kent. As a result of all this information, the decision was taken to look in the box this afternoon:

We were not sure whether the adult owl would be in the box and they have been known to attack in these circumstances. Therefore John was protected with safety specs and a cycling helmet

The normal number of chicks for tawny owls is two or three and so it was very surprising to find four chicks in the box. Thankfully there was no adult in the box, but there was one watching on from not far away.

All four chicks were in really good condition and of quite similar size
This was the smallest of the chicks

By the next post I should have a bit more detail on the chicks. Once John had returned them to their box, he took a photo of them snuggled back together – there’s not much room in there:

Elsewhere in the wood, I am really pleased to see that the green woodpeckers have decided to nest in the same hole that they have used for the previous two years. It is only about a metre and a half off the ground and easy to get a camera on:

Last year we found numerous beautiful white helleborines in the wood:

May 2025

We have been looking for them again this year but have only found a couple of small sprouts, nothing like the tremendous display of last year. We did, however, stumble upon a previously-undiscovered second patch of common twayblades, another type of orchid:

It is buttercup time in the meadows. We love this time of year when our shoes are yellow with buttercup pollen as we come in from the meadows:

There are over thirty different species and hybrids of buttercup to be found growing in the UK. The great swathes of buttercup that flower here in early May, particularly where the grasses are cut shorter, are all bulbous buttercups, Ranunculus bulbosus. These grow from a swollen underground corm that gives them some drought resilience, useful because they are found in dry chalk and limestone grasslands such as the meadows.

The taller meadow buttercups, Ranunculus acris, are now just starting to appear along the hedgerow edges as well.

The really easy way to tell the difference between the two is to look at the sepals growing below the petals. On the meadow buttercup on the left the sepals are pointing upwards, but they point downwards on the bulbous buttercup on the right

Meanwhile vast numbers of oxeye daisies are waiting in the wings to have their moment of glory shortly.

We have had some rain, an event so rare of late that I feel obliged to mention it. As the first few plump drops fell after such a dry spring, a frog appeared seemingly from nowhere:

Having the soil softened by rain is really good news for the birds and badgers who need to get at the worms to feed their young.

It has been some time since I’ve seen all three badger cubs together and I fear that we might already have lost one of them:

The daily peanut feeding time remains a very popular event, eagerly anticipated by the badgers, foxes and unfortunately also by the magpies:

And here is a magpie with another of the slow worms. However, slow worms can shed their tails to distract predators and, happily, it looks like this might just be the tail of the reptile:

There is something very interesting going on in one of the bushes in the meadows. A rare wasp, Polistes biglumis, has made a nest in some wild privet. Rather unimaginatively, we are calling her Big Pol and have been keeping an eye on her to see how she is getting on. This species is usually to be found in high-altitude meadows in the Alps and Apennines but, in 2020, several individuals were found nectaring on flowers at Samphire Hoe Country Park just down the coast. But, so far as we can tell, this may be the first time that a Polistes biglumis nest has been found in this country:

Big Pol and her nest. Another Polistes species arrived in the UK in 2003, Polistes dominula, the European paper wasp. But P. dominula has orange antennae and Big Pol has black

A scientific paper was written in 2020, following the discovery of this species at Samphire Hoe. The authors speculated that a mated female may have been carried from the Alps on a tourist car arriving at Dover. This car’s first stop was then the country park for the occupants to have a walk around after their long journey

Big Pol spends a lot of time guarding her nest but, when she was away, I was able to take a macro photo into it, showing that a single egg has been laid in each cell:

These eggs will hatch into larvae in due course and Big Pol will feed them with chewed insect meat, particularly caterpillars. Then, when the larvae become adults, they will switch to feeding on nectar.

Small blue butterflies have arrived in the meadows:

This is a male with that sprinkling of blue scales on his wings

Wall butterflies seem to be having a jolly good year here and there are many more around than normal. Here is a mating pair

There are also lots of these small but silly moths fluttering along the hedges this year. I say they are silly because the males really can’t fly very well with those ridiculously long antennae:

All across the country swifts are now arriving back at their breeding sites after their long journey up from Africa. Our boxes, however, remain resolutely empty:

As I anxiously check the cameras several times a day, I remember myself as a parent of teenage children, trying not to fret as I awaited their return from a Friday night out. Well, my children always rolled home eventually and I do hope the swifts will too.
