Environmental Variability Shapes Life‐History Trade‐Offs Within and Between Populations of a Long‐Lived Seabird Life-history theory predicts a trade-off between allocation of resources to reproduction or self-maintenance, yet how environmental variability shapes this trade-off remains poorly understood. We sho...

Four Red Admirals at Tregothnan this afternoon - the first I have seen this year. I wonder if there has been an arrival of migrants.

Certainly seemed to be in the last week or two across Cornwall. Saw a couple around St Ives along with a couple of Painted Ladies and a HBHM recently!

A first summer American Golden Plover which appeared today at Otmoor - a new county bird for me and quite a few others. Last one was in c 2012.

Ash dieback is having some odd disturbance effects in ancient woodland. The extra light under dying ash canopy is allowing these wild roses to go crazy, scrambling up the tree trunks to heights of 7 m, forming these funky columns.

My morning walk along the gas terminal rocks in Easington was interrupted by a shout from Spurn when this Great Reed Warbler was trapped. Very welcome as I’ve been abroad when the last couple turned up, so thanks once again to the ringers #spurnbirds

There’s a small chance of poisoning in the area - you can report it to the Natural England hotline on 0800321600 and they might test it. I think APHA might still be testing carcasses for Bird Flu so that’s another potential avenue you could go down.

@liamlangley1.bsky.social found a yellow-browed warbler singing in Trewyn Gardens this morning. It was also a good excuse to visit the Hepworth Sculpture Gardens at their most beautiful.

Yeah I walk through the gardens several times a week and not heard anything (might have heard a single call in October but nothing concrete). I wonder if it’s just the sunny weather causing them to sing pre-departure? It’s a subtle song that’s quite different from the call so maybe easy to miss?

Amazing moment this morning when I bumped into this singing Yellow-browed Warbler (end of video) in Trewyn Gardens, St Ives after finding one on Penryn Campus on Thursday! A welcome patch tick and an unexpected addition for my @patchbirding.bsky.social list! I wonder where it wintered? #UKbirding

You need to make AI guidelines for your lab Here's why you should, and how to start

“first drafts of Results, Discussion, and Introduction should be the trainee’s own work. AI can help with grammar…tightening prose…critiquing the logic of an argument you’ve already made. But the hard part of forming the argument needs to be yours.’ blekhman.substack.com/p/you-need-t...

Cormorants are difficult birds to handle so it is important to have good control of the neck at all times whilst handling. It is also important not to hold the neck too tight. This means that injury to the bird and the handler can be prevented.

Cormorants are difficult birds to handle so it is important to have good control of the neck at all times whilst handling. It is also important not to hold the neck too tight. This means that injury to the bird and the handler can be prevented.

It has been a couple stormy days at Skagen so night catching over the last couple days has been possible, but not successful.

So it was a real surprise to be able to hand catch this Cormorant last night.

It was even already carrying a ring. So hopefully we get some cool data from that.

A Grey Plover say on a dark rock facing right with the sea in the back ground. The bird is grey above, spangled with white and black across the wings and mantle, and pale off white below. The head is pale with a dark grey cap and a grey spot on the ear coverts. The bill is black and the legs are grey.

Birding and Blagging Back in May 2017 I somehow blagged my way into Birdwatching magazine as the guest on their Back Chat page. I still don’t know how I got away with it, even if they did edit down some of my gull…

Almost 10 years since I got away with this…
