Invasive Species in Nest Boxes

In 2018, NestWatch sent out an online survey to investigate how many people had experience with non-native birds in their nest boxes. The survey explored peoples’ knowledge of House Sparrows and European Starlings, both non-native species in the United States and Canada, where the survey took place. We were interested in peoples’ attitudes towards managing non-native species, especially if people encountered them in their monitored nest boxes.

We are grateful to the many people who took time to fill out our survey. Because of you, we have a better understanding of the impact of nest usurpation, and how people are playing a role in reducing the number of nests that fail due to usurpation by non-native species. Find out what we learned in our latest blog post.
