Hard to believe I’m watching snow fall now after a day like yesterday. Beautiful walk full of amazing nature encounters in the oldest migratory bird sanctuary in North America. Saw a few snow geese 😂. I’ll share more after I get through the photos! 🌿 #birds #prairie
Large buffalo rubbing stone in the foreground of a wide landscape shot of prairie and blue sky. Thousands of snow geese on a prairie lake. Tall metal cut-out sign in front of a wooden rail fence with brown prairie and blue sky behind. Sign marks the head of the Grasslands Nature Trail in Last Mountain Lake National Wildlife Area. Brown grass stretches to the horizon under a blue sky with wispy clouds. There is a fence on the horizon.

Substantial losses of #Arctic sea ice concentration are found in October. The largest declining trends extend from parts of the East Siberian Sea to the Chukchi Sea.

Sea ice concentration = fraction of ice-cover. More info on recent Arctic climate: doi.org/10.1175/BAMS...
Graphic showing a polar stereographic map of October 2024 Arctic sea ice concentration anomalies with anomalies from -50% in red shading to +50% in blue shading. More areas are below normal than above normal.

We have a new paper out, in which we use brute force to identify combinations of land use/management changes which navigate the triple challenge of climate change, biodiversity conservation and food production: www.nature.com/articles/s41... #ConservationScience 🌍 @rspbscience.bsky.social 1/

Are you interested in the calls that waders/shorebirds make?
@waderstudy.bsky.social have kindly made a 'Perspectives' article available as 'open access'.

#MusicChallenge folks! Please join me starting tomorrow for a new #BirdSongs challenge featuring our feathered friends, birds! 🪶🐦🦉

Below, I'll post photos of #birds along with vital info for you to use as inspiration in selecting your song (not theirs!) for the challenge. Have fun! #MusicSky #Music
An infographic that has three watercolor painted birds, one blue and orange bluebird with the words hosted by Dani Shaw dot me at the top. A black-capped chickadee with a black back, yellow belly and white face sits on the BirdSongs hashtag. The words below state "Celebrating birds and music. Use birds posted in this thread as inspiration for your tunes." A green and yellow bird sits on the MusicChallenge hashtag. The background is a light blue and purple watercolor.

Deep breath checkpoint! If you're doomscrolling, unclench your jaw and take a few deep breaths as you enjoy this Brown Creeper creepin'

Shoddy camerawork and urban park audio, but the bird is too cute not to share

A week on from #StormAmy 🌬️ data from our tagged Whooper Swans show both storm assistance & storm displacement. Some birds made rapid migrations, others battled the elements – some out at sea for 55 hrs! As North Atlantic storms grow more frequent, understanding their impact is vital. 🦢 #Ornithology

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.

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