What happened
Researchers have confirmed the existence of a hybrid between blue jays and green jays, marking the first documented case in the wild. The hybrid was spotted in San Antonio, Texas, by a local birder named Donna. Genetic analysis confirmed it was a mix of the two species, which have historically been isolated due to their differing habitats. Climate change has facilitated the northward expansion of green jays, while blue jays have also moved into new areas, often influenced by human settlements. This hybridization highlights the unexpected consequences of climate change on wildlife and ecosystems. Although the hybrid has not been formally named, potential names include 'grue jay' and 'bleen jay.'
