Out @animalecology.bsky.social today - a paper with David Ewing in which we explore the #HPAI outbreak in the terns. We find bird-to-bird transmission to be the main driver of infection and estimate the probability of mortality to drop from 0.26 to 0.14 from 2022 to 2023: doi.org/10.1111/1365...

1/ Despite a reasonable difference in size, Cormorants and Shags can be quite difficult to differentiate unless side by side!

In this thread ⬇️, we take a look at some of the key differences between adults and juveniles... #seabirds #birds @btobirds.bsky.social @jncc.bsky.social @rspb.bsky.social
Graphic displays a Cormorant photographed by John Harding/BTO (left) and a Shag photographed by Liz Cutting/BTO (right). The species are labelled with their English and Latin names, Phalacrocorax carbo and Phalacrocorax aristotelis, respectively. Each image is labelled with key identifying features. For the Cormorant, these are: 'Heavy bill and a gradually sloped forehead', 'White chin', 'Blue sheen', 'White patch on thigh', and 'Variable amounts of white in the neck'. For the Shag, these are: 'Breeding crest', 'Green sheen', 'Lacks white in chin and neck', and 'Light bill and a steeply sloped forehead'. The Seabird Monitoring Programme logo is found in the bottom right hand corner. 
The caption reads: '1/ 1/ Despite a reasonable difference in size, Cormorants and Shags can be quite difficult to differentiate unless side by side!

It's out! It's a great read! Highly recommended 💪

Now can someone do the same for battery? 🔋🔋🔋

Solar is giving the world **cheap daytime** electricity.

Battery changes the game: it gives that solar electricity**when you need it**.

What do you do when you find a publication which you reviewed gets published with clear errors which you pointed out in your review? 🧪 #science #peerreview

I would never have guessed frigatebird (any of them) but how interesting their distribution! Has anyone ever looked generally at the ecology (& spatial distribution) of (obligate) kleptoparasitism?
