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

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...

#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.
