Did you know? Mourning Doves raise up to six broods a year! Each clutch typically consists of two eggs, and after two weeks of incubation they hatch into chicks that only need another two weeks in the nest before they're ready to fledge! Are Mourning Doves nesting near you this spring?

Happy June! The weather is looking up and lots of folks are spending time outside. But before you dig out that equipment for summer fun, make sure you check it over for nests! Some birds love to nest on things like boat moorings, tailgates, tires, and other similar spots. If you find a nest, it's best to leave it alone while the nest finishes up and shift to a different activity in the meantime.

Nestlings are fledging from nests and making their way into the world. Most will stick around their parents while they learn how to fly more strongly and forage for themselves. What birds have been fledging in your neighborhood? 🦉

Have you ever seen a piece of a plastic woven into a bird's nest? This summer, we’re asking all NestWatch participants who find the nest of an American Robin, Gray Catbird, or Northern Mockingbird to photograph that nest from the top and from the side, and then upload the images when reporting data to NestWatch. We’re looking for both nests with plastic as well as plastic-free nests! Learn more about how you can help: https://nestwatch.org/blog/join-our-new-study-on-plastics-in-bird-nests/

We get lots of questions about how nesting birds deal with high heat this time of year. It's normal for birds to breathe with an open beak when temperatures climb, and most nest boxes are sufficient shelter from the heat, but if you want to do more for your birds, follow our suggestions here:
