For over a decade people like you have helped scientists by collecting valuable data on the successes and failures of nesting birds.
Why do birds hang out in nest boxes in the winter? They’re basically looking for a cozy place to sleep—alone or in groups!
It’s not too late to enter light pollution data for those participating in our Barn Swallow light pollution study.
Now when you filter your nest sites by groups, your group filter will stay active until you change it. Enter your data now to get counted!
The Cornell Lab of Ornithology will be closed December 25–January 4, for winter break. We’ll see you back here on January 5th.
