Black-throated Blue Warbler (Setophaga caerulescens)

Posted on Oct 3, 2015

For those of you that guessed Black-throated Blue Warbler for our confusing fall warbler question, you would be correct! As you may have noticed both the prior photo and this photo of the Black-throated Blue Warbler features them in-hand after receiving a small silver band on one of their legs. While the birds migrate from the northeast, upon their return and possible recapture, ornithologists can gather a great deal of data as to where the birds may have traveled to, whether they return to the same breeding grounds year after year as well as what their overall state of health appears to be. Information gathered through banding can help preserve critical habitats and resources for these birds as well as many other species that utilize the same habitats as well.
