This bright yellow bird is a rare hybrid that was banded at Powdermill Nature Reserve, the museum’s environmental research center, in spring 2017.
This hybridization occurs when a golden-winged warbler mates with a blue-winged warbler. This individual was just the 12th Lawrence’s warbler banded at Powdermill in our 55 years of banding.
Powdermill Nature Reserve’s avian research center is part of Carnegie Museum of Natural History’s biological research station in Rector, Pennsylvania. The research center operates a bird banding station, conducts bioacoustical research, and performs flight tunnel analysis with the goal of reducing window collisions.
