Fig. 3 from the article: Average 24-hour cycle in migratory activity (quantified by reflectivity) relative to solar noon (a) or local dusk (b) across all days throughout the fall and spring migratory periods at each of the seven stations across Alaska, with the cycle corresponding to each station color-coded by longitude.

Fig. 6 from the article: Fraction of cumulative migratory activity (η) within each sampling period falling between dusk and dawn versus night length.

NEW PAPER: Radar data from Alaska show birds shift to diurnal flights as nights shorten, but peak migration still clusters near solar midnight—highlighting strong stabilizing pressure on flight timing that overrides pressure to maintain nocturnality.

Rare blue-and-green hybrid jay spotted in Texas is offspring of birds whose lineages split 7 million years ago The hybrid bird is the product of two species whose habitat ranges began to overlap a few decades ago, potentially due to climate change, researchers said.

Something cool to start your weekend: a Blue Jay x Green Jay hybrid from Texas! #ornithology

Two days before WaderTales celebrates its 🔟th anniversary.

What an honour to open the 50th @waderstudy.bsky.social conference with a plenary on Spoonbill migration culture on the beautiful stage of DOT in Groningen. The Spoonbill-inspired concerto 'Solanum' by Tjibbe Stelwagen and Caspar Kootstra made for a perfect tandem wt the arts. #ornithology

Obviously, there's bigger news happening right now, but Senate Republicans just voted against releasing the Epstein files. Every Democrat voted to release them. Susan Collins was the deciding vote to protect Trump and others named in the files.

Vagrancy into the North Atlantic must be pretty lethal for European woodland birds.

This is an exceptionally good thread, on the situation with publishing in academic journals. Virtually all of it applies to #ornithology, #ecology & #conservation journals. 👇

The absolute collapse of Willow Warblers in southern Britain doesn't get talked about enough. One of the commonest migrants 30 years ago.

Exogenous xenosurveillance allows us to sample peripheral blood of wildlife hosts using mosquitoes. We can then identify hosts using barcodes and screen for host pathogens.

Just published today! Our group used mosquitoes as flying syringes to conduct surveillance on pathogens of turkeys, white-tailed deer and invasive wild pigs. Not only could we detect DNA and RNA viruses, we could estimate prevalence! 🌎🧪👩‍🔬

Photo of an Amazon Parrot by leeanthonyjeys/Flickr. A speech bubble above the bird says: A man walked into a bar with a parrot on his shoulder. The bartender said, "Does the animal talk?" And the parrot replied, "I don't know."
