A Spotted Flycatcher perches on a piece of wood. White writing over the green background reads: Rivers vital for Spotted Flycatchers according to new research. Image credit bottom left reads: Spotted Flycatcher by Edmund Fellowes/BTO.

1/ Spotted Flycatchers are in trouble, declining by 92% in the UK between 1967 and 2020. New work led by @cateden91.bsky.social & involving BTO has revealed the importance of rivers for the survival of this Red-listed migratory species. ⬇️ #Ornithology

Three Velvet Scoters (Melanitta fusca) and two Surf Scoters (Melanitta perspicillata) among the grey waves in Liverpool Bay. The photo was taken in February 2023 when the seaducks were unusually close to the shoreline at Llanddulas.

A great day to be counting waterbirds for the monthly @webs-gsmp.bsky.social survey - and the 60th annual @wetlandsint.bsky.social count.

First two pages of the comic. Page one features a Kittiwake in the sky wondering where all the birds have gone. Page two shows how climate change impacts the diet of seabirds. One fish looks healthy, the other ones looks smaller and poorer quality.

Grab a cuppa and read our Seabird Poo comic! ➡️ http://www.bto.org/S... ☕📖

Discover how seabird scientists collected bird poo and analysed its DNA contents to determine the types of prey consumed by Shags and Kittiwakes! 😮 #Ornithology
