I recently noticed an unexpected bird singing in the Lincoln Yards site near the Hideout — a dickcissel. Here's my story about it for @chicagomag.com: www.chicagomag.com/city-life/th...

The Birdbrain Case for Stopping Lincoln Yards Development

The discovery of grassland-loving dickcissels on the site of Sterling Bay's stalled megadevelopment suggests the value of preserving open land.

Piping Plovers move pretty fast. If you don't stop and look around once in a while, you could miss them.

Blue Star will now be known as Ferris. 1/4

Hiya! I'm El.

The El (for Elevated) is Chicago's transit system. Just like our Piping Plover family at Montrose, the El connects the city of Chicago, its surrounding suburbs, and the community it serves. 1/2

In the future definitely call Chicago Bird Collision Monitors: 773-988-1867. Please save their number! All birds who hit windows should be checked out by a wildlife rehabber. Just because they fly away doesn't mean they don't have brain trauma. Thanks for caring!

This is a black bellied whistling duck. They’re normally in Texas and Mexico, so this guy is quite lost. Lots of birders geeking out in Lincoln Park right now, haha. #chicago #bird

Eight-legged Imani?!
During the first weeks after hatching, chicks are unable to maintain their own body temperature. The chicks spend much time tucked in under their parents' wings to stay warm. This is called "brooding."
