Can't see now, but male and female from what I could make out from Brands Bay hide. Worth looking out for.

Looks to be a pair of Smew in with Goldeneye off Redhorn Quay @dorsetbirdclub.bsky.social

Poole (Dorset) peregrines have been very active in the higher nest box recently. Adult male and female spending considerable time at the box and the male recorded scraping. This year's juvenile male (HG) is still present. If he is still around in Mar/April will he help or hinder?...we'll see.

Congrats CD on your well-earned achievement!

Hoping to deliver a live streaming Hobby nest camera this year. We have several cameras up on nests/baskets that were used last year; some are looking promising but we won't know for sure until eggs are laid! Average laying date is approx 14th June....🤞

New paper alert!

Really excited to see this work from a postdoc with Steve Votier @heriotwattuni.bsky.social published in Ecology & Evolution!
In it, we use existing bio-logging data to study competition and facilitation in foraging gannets.

New experiment challenges long-held theories on how migratory birds navigate New research challenges the long-held belief that all components of the Earth's magnetic field, especially total intensity, are essential for accurate navigation.

Research by Bangor University found that birds, in this case, Eurasian Reed Warblers (Acrocephalus scirpaceus), use only the Earth's magnetic inclination and declination to determine their position and direction.

I'd like to join please, Sean

Please add me.

Seb gave us a wonderful overview of Wild Woodbury, and took part in very lively Q&A together with our other speakers at the end of the day. Many thanks.
