WOAH BABY, these ducks are chilly!!! When the temperature is super low, water vapor can’t integrate into the air, so we instead get beautiful steamy plumes that make waterfowl look MAJESTIC! Stay warm out there, folks! 🦆

If you, like me, have spent all month looking at birds instead of planning your Halloween costume - fear not!! We have your back. Here are three quick and easy outfits for tonight!!

#coolbugalert I found at least 6 of these Yellow garden spiders on the Wild Mile! @urbanrivers.bsky.social put my hand behind the web to show you scale! 🤯 #homeriverbioblitz

I realize I’ve posted almost exclusively about our wildlife cameras on this account. If you’ve enjoyed that, great news - you can help me out! Here’s acclaimed actor Nick Wesley explaining how!

“let’s put out cameras to study wildlife behavior!” The behaviors:

Do you like beer? Awesome - come to our Block Party on July 13th! (It’s 3-8pm at 905 W Eastman Street)

For the second year in a row, we celebrated solstice w/ a Polish accent on Chicago’s #WildMile w/ @urbanrivers.bsky.social. We hope that you can join us next time 🌺

“Chicago is so dangerous!” The crime in Chicago:

At the height of the Chicago River’s pollution, there were only 5 fish species that could be found in the river. Now, there are 77! Here are four of them.

Do you enjoy needless loitering, drama, and making a ton of noise in public? Then you’d get along just fine with a Canada Goose! It’s deranged unprovoked aggression season (aka nesting season) - remember to keep a healthy distance from these heathens!

We’re excited to announce our newest project: The CyberReef! The result of an incredible cross-sector collaboration, this initiative repurposes Cybertrucks to create artificial freshwater reefs. For more information about the CyberReef, please email [email protected]

Chicago loves a critter! The newest one, a "Remarkably Rotund" beaver, now has a name, thanks to @urbanrivers.bsky.social. New shirts online now! Sales benefit our friends at Urban Rivers! #raygun #urbanrivers #chicagoriver #idabeavwells www.raygunsite.com/products/ida...

I am absolutely DELIGHTED to announce that a name has been selected (through a democratic process) for our beloved South Branch Beaver. Meet Ida Beav Wells! Her presumed kits, frequently sighted alongside her, shall be named Plumpton Sinclair and Chewy Garcia.

A "remarkably rotund" beaver is making a splash on the South Side — and she needs a name. 🦫

Timeline cleanse: There is a very hefty beaver living and thriving on the Chicago River and I personally think that the city should name her Sigourney Beaver but my fellow citizens have come up with some other good suggestions 🦫💚 blockclubchicago.org/2025/02/18/a...

Happy Valentines Day to those who celebrate! If this post gets more than ten likes I’ll post all the NSFW versions.

Once again, I spent all year taking bird pictures on company time. And once again, I found a way to justify it. Please enjoy our 2024 annual report! urbanriv.org/annual-reports

Kayaking the Chicago River has become one of my favorite activities. I’m so grateful to organizations like @urbanrivers.bsky.social for their work restoring this important ecosystem www.youtube.com/watch?v=VIin...

Don’t miss the hottest event of the winter! Join us on Friday for Piggies on the River: the Royal Chicago Pigs-in-a-Blanket Festival! Malört, coffee, pigs in a blanket… you name it, we got it! More information below, and on our website. urban-rivers.ticketleap.com/piggies-on-the-river/

When our volunteers discovered this cursed painting in the river last summer, I thought we’d never find anything creepier. Today I was proven wrong (by the same volunteers).

I’m declaring 2025 Year of the Heron. Look at these creepos.
