Hopefully things are on the up Graham, at my study site in Hampshire we had a low point around 2004, but since then they have been increasing. We already have 15 singing males back in the study area this year which is nearly back to the numbers from around the late 1990s!

The start of my mothing season has been a bit hit & miss, with being away them bogged down with work. 10/04/26 was a tad windy so not surprised to get 40:12 but was surprised to get 5 diamond backs & 1 ea nutmeg, turnip moth and Dewick’s plusia amongst the usual suspects #migrantmothuk #teammoth

New study alert! Female Daubenton’s bats foraging at the cold edge of their range take turns using the same feeding spots at different times of night, thus reducing competition and helping them cope with the cold.

Curlews are in crisis. Ground-nesting birds aren’t fledging enough chicks due to farming, predation, development & climate change. Saving them means tackling our biggest environmental challenges.

Incredible ringing recovery this AM by Stour Ringing Group of a Kestrel caught near Arne which was carrying a Dutch ring and a sat-tag. Well done for getting the data so quickly. Amazing movement for a bird that typically isn’t considered to move large distances. @dorsetbirdclub.bsky.social

I know you’re not Chris, they just done see it as a problem. It’s all very depressing.

This is what it was like two weeks ago, same roost, same disturbance, more birds. Our wildlife doesn’t stand a chance unless things change, it’s seems ‘dog is king at the moment’ 🥲

That was until this spaniel ran through the roost and flushed everything. I missed the first and main flush, this was the aftermath, with smaller groups still being flushed. We have a strategy in place in Hampshire to protect these birds from disturbance, but it’s just not working.

There was a modest roost of c. 150 Dunlin and 100 ringed plovers at high tide on Gunner Point, Hayling Island. Down from the c. 1000 birds a couple of weeks ago. #ukbirding

Another bat survey today in South-east Hants, exploring tunnels on Portsdown Hill. The highlights for me were another Tissue, Buttoned Snout and Bloxworth Snout. Also a dozen or so herald moths and over 50 peacock butterflies. #teammoth

Developers met ministers dozens of times over planning bill while ecologists were shut out Exclusive: Leading ecologists say warnings over threat to wildlife have been ignored in drive to build 1.5m new homes The scale of lobbying of ministers by developers on Labour’s landmark planning changes, which seek to rip up environmental rules to boost growth, can be exposed as campaigners make last-ditch attempts to secure protections for nature. The government published its planning and infrastructure bill in March. Before and after the bill’s publication the chancellor, Rachel Reeves, and housing minister Matthew Pennycook have met dozens of developers in numerous meetings. The body representing professional ecologists, meanwhile, has not met one minister despite requests to do so. Continue reading...

A couple of interesting nights on the way as our weather is influenced by ex-hurricane Elin. Tonight, we could see the 1st arrivals in S. Ireland, SW Britain & perhaps along the south coast. Monday will be very warm with air from N. Africa, and perhaps the most likely night for migrants. #teammoth

My nephew even had one on his front door last week, and I know of a few others that have caught them so must be fairly common this year.

Gypsy Moth - a few have been caught locally so no surprise really, but a new moth for me!

82:48 to my South Hants VC11 garden last night. Some nice bits - Jersey & Garden Tigers, shaded broad-bar, rosy rustic, four-spotted footman & a diamond back, but this Gypsy Moth was the star, a new moth for me. Great antennae - face on it looks like a brown long-eared bat #teammoth #migrantmothuk

It’s now 21 days since my last plover post, we have found nest 11, outside the enclosure. It only had one egg, but the female was incubating it. Although she seems to have stopped now. Meanwhile, one chick from the brood 4 reported last time is still doing well. Fingerscrossed. #ukbirding

My 29th year monitoring nightingales in Hampshire this year, and it looks like a good year. The first birds were recorded back around 7th April, at least 16 males held territory locally and 5 breeding females confirmed. So far 3 juveniles ringed in 2025, proving breeding success. #ukbirding

I'm so excited to share that this springtail, one that seems to have rapidly appeared in graveyards and gardens across the UK, now has a proper name: Entomobrya petri!

I hope this will be the first of many new species descriptions, allowing us to track our rapidly changing springtail fauna. 🧵⬇️
