Celebrate July 4th with Our All-“American” Slideshow
There are 19 bird species in the U.S. and Canada that have “American” in their common name. We took a deep dive into our Macaulay Library and Birdshare archives to create this beautiful slideshow that features every single one. Happy 4th of July!
Oh, Canada? In honor of Canada Day (July 1), let’s take a moment to celebrate news that the Gray Jay has been officially renamed the Canada Jay. (eBird and All About Birds will update to the new name in August.)
