It's prime owling season and like clockwork, the hunt for these charismatic birds has ruffled some feathers. It's important to respect an owl's space when observing. We are often asked how close is too close. We can't tell you (there's no simple answer) but the owls will.

Join the celebration! Next week we're gathering virtually to look back at what we accomplished last year and get excited about plans for this one. Be among the first to see what's in store for Chicago birding! chicagobirder.org/events/2023/1/…

Migration is starting! This Northern Waterthrush and his kin have shown up in our area. These are one of our earliest migrant warblers in the fall. It's a good reminder to get the bird tape on your windows and save the CBCM hotline # to your phone: 773-988-1867. (📷Jeff Bilsky)
