Started today's #OctoberBigDay by hanging out with Ken Rosenberg and migration-guru Bill Evans 😊 Cornell Lab eBird

Cool paper by Helen Rößler and my former LynchLab labmate Maureen Lynch on how Gentoo #Penguin calls differ based on presence of other species! 🐧Lots of #Antarctic #CommunityEcology implications. doi.org/10.1093/ornith… The Auk

Birds tell us that the health of our nation is at stake. The 2022 #StateOfTheBirds report finds that 70 species are on track to lose half their population in 50 years if no action is taken. We can reverse bird declines if we work together. StateoftheBirds.org #BirdsTellUs

The 2022 U.S. State of the Birds report has been issued by Cornell Lab and many bird conservation partners. Read the report: StateoftheBirds.org

#Eels have piqued the curiosity of scientists for millenia. The #Sargasso is thought to be where they spawn but eels had never been tracked there. Until now. For the first time ever, we followed eels to their spawning grounds #europeaneel #anguilla 🐟 nature.com/articles/s4159…

Old Blue Eyes - from a distance Brandt’s Cormorant is just like any other black cormorant around the coast. Get up close and those spectacular sapphire eyes and oil slick plumage make it a very special bird.

REQUEST FOR PHOTOS. Do you have photographs of Desertas Petrel and / or Cape Verde Petrel for our research into field separation and identification of the two species. We would be truly grateful.

The eBird Taxonomy update is HAPPENING NOW! Expect changes to #bird names and life list totals as we update millions of eBird records with the latest splits, lumps, new species, name revisions & more. Stay tuned for additional details #birding #BirdTwitter bit.ly/3DrTUkX

Updated eBird trend maps are here! Take a look and explore what all of our birding data are able to produce: science.ebird.org/en/status-and-…

Here is a penguin knowledge test for you in honour of #WorldPenguinDay. This was taken on Cuverville Island, Antarctic Peninsula, in 2021. What's "out of place"? 📸Chloe Kaczvinsky

I'd like to take this opportunity to pivot to an iconic US endemic we *KNOW* still exists and that is *GOING TO BE EXTINCT* in the next 30 years if we don't do something drastic, fast. The Saltmarsh Sparrow:

It's time for the annual eBird taxonomy update! Read more here: ebird.org/news/2023-taxo…

It has finally happened. HPAI has been confirmed for the first time in Antarctica. Two skuas found at Primavera Station (Arg) and analysed by molecular biologists of the Spanish polar programme. Fingers crossed for the penguins and the seals next season 😕🤞🐧

Thrilled to be featured in the latest eBird Reviewer Spotlight. Hopefully our recent work on improving the review of off-shore #eBird records will lead to more quality #seabird data! ebird.org/news/ebird-rev…
