It’s not been a great year numbers wise at Titchfield Haven NNR, but today the 200th grasshopper warbler of the year was ringed. This is now the highest total since 2014 when we ringed 341 from 29 sessions, this year there have only been 19 sessions so far. #ukbirding #birdringing

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.

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
Gypsy Moth - a few have been caught locally so no surprise really, but a new moth for me! Face on these antennae look like the big ears of a brown long-eared bat This pic a took a few years ago. A brown long-eared bat with ears up. I may have to start a new feed of moths that look like bats!

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. 🧵⬇️

I’ve had to step back a bit as it was all getting a bit overwhelming, especially when recording other stuff too. Put the the trap out last night and still had nearly 300 moths. I did have 2 small marbled and 6 light crimson underwings plus a host of other stuff, but was too much before work

Dark Crimson / Light Crimson Underwing ID tip - The discal spot is adjacent with the postmedian line and the antemedian line is pointed near the dorsum / The discal spot is isolated from the postmedian line and the antemedian line is curved near the dorsum. #MothsMatter #TeamMoth

Since my last post we have found two more nests, nest 9 was outside the enclosure & quickly predated by crows. Nest 10 was evidently missed as when I found it yesterday, the first chick had already hatched. By midday today 3 were running around but egg 4 was sat with just a hole. #ukbirding
Neely hatched chick - three eggs to go Two newly hatched chicks two to go Chick approaching parent for a quick warm up Egg four - still not hatched and being left for longer periods now. Maybe it won’t.

Migrant action last night was limited to two species, foot-spotted footman of which there were 8, and a rush veneer. #migrantmothuk
Four-spotted footman, one of 8 last night, all males

Every one I know locally caught four-spotted last night so guess they were migrants

Mothing has continued throughout the day, five lure put out and so far 9 orange-tailed clearwings and a red-belted have been attracted. Also flushed another silver Y out from the garden shrubbery! #teammoth #migrantmothuk
