    The latest research paper to include NestWatch data is not your average avian study. Your data contributions were recently put to use in an examination of gray ratsnake climbing behavior. The study authors were interested in which factors correlate with ratsnake climbing forays, and they wondered if the timing of nests (and thus a seasonal abundance of eggs and nestlings) was an influence.

  • Where can I download construction plans for predator guards?

    Recent research using NestWatch data suggests that, on average, nests in boxes with predator guards had success rates 6.7% higher than nests in boxes without guards. And while all types of guards were correlated with improved nesting success, birds nesting in…

  • Insects are in my box! What should I do?

    In most cases, nothing.

    Ants are commonly found in nest boxes, but if you specifically have fire ants (most common in the southern US) then we have tips to discourage them on our Dealing with Predators page.

  • Predator Guards Carry Their Weight

    It took just four years to answer the decades-old question of “Are predator guards on nest boxes actually helpful?” With the power of citizen science, NestWatchers helped us use the best science available in a national study of cavity-nesting birds.
