The largest native waterfowl in North America, the trumpeter swan, captured mid-migration. Wingspans up to 10 feet, yet they move with incredible precision.

There's a new guest post on the WOS blog! WOS Research Grant recipient Shelby McCahon describes her research into whether agricultural pesticides are impacting migrating shorebirds in the Prairie Pothole region. #ornithology wilsonsociety.org/2025/11/12/g...

The Slender-billed Curlew was declared extinct in October 2025.

At #AEWAMOP9, delegates paid tribute to it, with this rare taxidermied specimen on view.

In an increasingly divided world, how do strangers become friends? Parakeets might have something to teach us! New paper on formation of affiliative relationships, led by Dr. Claire O’Connell doi.org/10.1098/rsbl...
Graphic showing the paper title “Monk parakeets ‘test the waters’ when forming new relationships” in the journal Biology Letters. Also features photos of the co-authors (Claire, Annemarie, Gerry, and Liz) as well as the issue cover photo of two marked monk parakeets from Claire’s work grooming each other. Also shown are some of the main plots of the paper showing how the parakeets escalate their behaviors from low risk/low investment (like proximity) to higher risk/higher investment interactions (like preening/grooming)
