Last Call To Take Our Survey

Invasive, non-native bird species can cause problems in nest boxes; however, there is very little information on the scale of the problem. If you monitor nest boxes, please consider taking our survey by May 1 to help us learn more about this important issue, whether or not you have noticed invasive species at your own boxes. We developed this 10–15 minute survey to gather input from a variety of people who provide nest boxes for birds in the United States and Canada. This study is being administered by NestWatch; however, you don’t need to be a registered NestWatcher in order to participate.

This study has two parts: a spring survey (accessed here), and a follow-up survey after nesting season concludes (about six months from now). As a special “thank you” for participating in both surveys, all entries will be automatically entered to win a pair of Zeiss Terra ED binoculars valued at $400! We greatly appreciate your assistance, and we invite you to share this survey with friends and colleagues in your network. Thank you for helping to document the impacts of invasive species on native cavity-nesting birds. The survey will close May 1.
