Rare, chromatic avian crossbreed leaves researchers in awe
In July 2020, a birder named Stephen Gosser made an extraordinary discovery in Lawrence County, Pennsylvania. He stumbled upon a hybrid bird, a result of a unique mating between a rose-breasted grosbeak and a scarlet tanager.
The one-year-old male hybrid bird exhibited a captivating blend of characteristics. It boasted a rose-colored breast and white tummy, traits inherited from its mother, and a long, slender beak, a feature reminiscent of its father. The bird also had brown wings, a speckled chest, and a patch of red feathers on its throat, making it a sight to behold.
The discovery of this hybrid bird raises intriguing questions about the complexity of defining what a species truly is. Hybrids such as this tanager-grosbeak demonstrate the blurred lines between species, as they exhibit characteristics from both parent species.
The mystery bird was identified with the help of Bob Mulvihill, an ornithologist at the National Aviary in Pittsburgh. The results of the genetic test, published in Ecology and Evolution, confirmed the identity of the bird as a hybrid.
This discovery is significant because it has never been seen before in these two highly diverged species, similar to domestic cats and tigers. In fact, hybrids of highly diverged bird species are becoming more common, as stated by Daniel Baldassarre, an assistant professor at SUNY Oswego.
Hybridization, while not common, is not unheard of in the bird world. Only 16% of bird species have been documented hybridizing with other bird species in the wild, suggesting that hybridization may be more widespread than previously thought.
However, finding every bird hybrid that spontaneously appears is a challenging task. With the help of dedicated birders like Stephen Gosser, it may be possible to uncover more of these fascinating findings. The discovery of the hybrid bird serves as an incentive for birders to examine every bird they encounter, as unexpected finds can occur.
Stephen Gosser emphasizes the importance of this approach, stating that he will continue to keep his eyes open. Despite the uncertainty about whether the hybrid bird will be able to reproduce, the discovery is a testament to the wonders of nature and the importance of observant birders in uncovering its secrets.
