Currently, rose-breasted grosbeaks are passing through Georgia on their spring migration home to their breeding grounds. During this special time of the year, we are treated with the opportunity to see what is perhaps the most beautiful bird that graces our feeders—the male rose-breasted grosbeak.
The bird is adorned with bold black and white plumage. The undersides of its wings are rose pink. If that isn’t enough to dazzle your eyes, he also sports a brilliant red triangle emblazoned on its white breast.
At first glance, all adult male rose-breasted grosbeaks appear to be identical. However, if you look more closely, you will realize that you can actually tell one from another.
In order to accomplish this seemingly impossible task, focus your attention on the red triangle emblazoned on the breast of each male. It will quickly become apparent that each marking varies in size, shape, and brightness.
This will enable you to determine how many males are using your backyard as well as how long individual birds linger before resuming their migration.
