NestWatch is a nationwide nest-monitoring program designed to track status and trends in the reproductive biology of birds. Participating in NestWatch is easy and anyone can do it.
Observations will be added to those of thousands of other NestWatchers in a continually growing database used by researchers to understand and study birds.
For four days, February 17- 20, 2023, we’re calling on all bird lovers to do what you do best…watch birds and count every bird you see! Every count submitted helps researchers learn more about bird populations, such as where some species are thriving and where others may be on the decline.
