Thermal-imaging of two shearwaters in flight over St John's Valley on Lundy last Spring. As well as the bare parts, look at the radiation from the feathered wings!

Another yellow-browed warbler and a patch-tick woodcock from a foggy Aust this morning. Only goldcrest in the nets and a slow push of finches and redwing overhead.

Obviously travelling by train. Highlights were flocks of stork -migrating or staying?- and great white egret through the Black Forest 🚂

Thanks to the CASCB @uni-konstanz.de and @alexhhchan.bsky.social for hosting me today. It was a pleasure to see their exciting work on perception and decision making in person, and to talk about applied models of animal social behaviour.

Late to posting an early yellow-browed warbler, briefly through scrub at Aust on Monday morning. Otherwise, Siskin moving and single grey plover over. Despite the autumnal feel, still no redwing.

This is the photo that best captures how good Monday was on the Severn. The first sooty shearwater for Bristol, and the first for Avon since 1974 (📸: @aravindramesh19.bsky.social)

Monday’s Sabines gull was still on the foreshore, below the sea-watchers bench, at Severn Beach yesterday. Still Manx, terns and phalarope in the channel.

Big weather delivered an exceptional push of seabirds up the Severn today, including the first sooty shearwater for 45 years, grey phalaropes, sabines gull and Leach’s petrel.

Rounded off an excellent week with a Sabine’s gull from Severn Beach, pushed up the channel on squally weather. Also, 8+ Manx, comic and black tern, and spoonbill all on the river.

A hard few days at Severnside (with a wind direction just cutting us off from the seabird action down the channel).
Highlights have been juv. Yellow-legged Gull, wind-grounded migrants, and Black-headed Gulls from Poland and Netherlands in the same scope view.

Book-shopping with my son today, we found a book with an illustration of a micro-discovery I made as a MRes student.
The paper wasn’t breaking any ground, but I am proud of this particular exploration.

Lesser Whitethroat seem to always be an early season migrant at Aust - two caught this morning with first tennis ball Willow Warbler of the autumn.
Otherwise, two more crossbill overhead and a site first ring-necked parakeet. 🎾🎾

Three full grown birds, from two inaccessible sites around Bristol, colour-ringed today at a local rehabilitation centre.
All will now be released back to their nest sites.

Ten years after I ringed my first, our young ringing group in Bristol ringed our first peregrine chicks in the gorge.
Two males and female - below the iconic bridge, in a cavity peppered with Carboniferous sea-shells. 🪶🧪

I am always impressed by the diversity in size, shape and colour of gulls eggs.
These are all lesser black backed gulls nests, visited under license.

Ahead of habitat enhancement for seabirds on steep holm, we have done some baseline surveys for lesser black backed gull.
Among 150 nests recorded yesterday, we also recorded our first (early!) chicks of 2025.

Last night there was a moorland fire in the valley where most of England's twite are now nesting. This is terrible news.
