Gobsmacked to learn that this male Pied Flycatcher, currently feeding chicks at my coastal nestbox site in Eryri NP (and caught under BTO licence), was originally ringed as a chick over 150km away in the Lake District!

Struggling to get that perfect shot of your pet? Why not ask for professional help. I recently worked with handsome collie Pip and his mum, who said he “always looks crazed” in photos.

Like London buses, my second paper published in the space of a week! Working on the (substantial) impacts of HPAI on seabirds, it was fascinating to find that population changes in some of the hardest-hit species are reflected in @trektellen.bsky.social seawatch counts. dx.doi.org/10.1080/0006...
Impacts of highly pathogenic avian influenza on seabird populations in the North Sea are detectable in sea-watchers’ migration counts
Sea-watching counts provided evidence of declines in abundance of four seabird species during autumn migration, which were consistent with the timing of highly pathogenic avian influenza (HPAI) out...

Great to see Whitburn #seawatching data used (through @trektellen.bsky.social) With just 78 Bonxies logged in over 1000 hours observation in 2024, it has been the worst ever year since regular documented seawatching started here. 😢 #NEbirding #seabirds

I haven't been doing as much wildlife photography in the run-up to launching @pawsomepictures-uk.bsky.social, but it was great to get out yesterday and see the super Snow Bunting flock on the Great Orme (with a genuine snowy backdrop to boot!) #ukbirding

If only they could stay this cute forever! The first months of a puppy’s life are a great time for a photoshoot, so you have a memento of those magical times forming that special bond with each other 💕

The beach is probably my favourite place to shoot. Open vistas, golden light, and plenty of options for fun and games with the dog! Wherever you are in the UK, you’re never far from the coast, and we are blessed with some amazing beaches here in North Wales

A beautiful late-evening visit to my reservoir site yesterday. Herb-Robert proving it’s a rainforest by growing on a fallen tree, a metre above ground. Five eggs from the Nuthatches, and the Pied Flycatchers won’t be far behind…

Such a privilege to spend time in my two nestbox monitoring sites in the Carneddau - both around 250m elevation but with very different backdrops and characters. The season is now in full swing with the Pied Flycatchers back and nest building! Nests monitored under BTO licence

Lots of colour-rings to be found on Colonsay. Already this trip, we’ve resighted multiple Barnacle Geese, Hooded Crows and Choughs (plus our target Greenland White-fronts). Even saw - but frustratingly failed to read - a Twite from one of @jamiedunning.bsky.social‘s schemes! #ukbirding

A brilliant day - smooth crossing to Colonsay (sightings of camera 📷 Tystie, 📷 Golden and White-tailed Eagles) before we caught up with some 9 of our 12 colour-marked 📷 Greenland White-fronted Geese in the last of the light!

Making my way slowly north this week, towards Colonsay. I’ll be spending a long weekend trying to catch up with A3A and his pals. With a little luck, I’ll come back home with a laptop full of amazing migration data, and leave a setup behind to gather another winters’ worth of habitat usage data!🤞

A couple more favourites from this spring that never graced X, both taken in the wonderful ffridd that fringes the high Carneddau near home. Lesser Redpoll and Ring Ouzel - species I knew only as winter/passage migrants before moving to North Wales

I'd post a lot of my photos on the other place, but lost the will when it lost its way. Now I'm here thanks to the kindness of @botanybeck.bsky.social, it feels appropriate to start out with a @wildflowerhour.bsky.social photo! Green-winged Orchid and Spring Squill at Esgyryn, taken this spring
