Story summary

A hybrid jay was found in a San Antonio backyard, from a green jay mother and a blue jay father.
The finding is the first observed vertebrate hybridization linked to climate-driven range expansions.
Researchers from The University of Texas at Austin confirmed the lineage through genetic analysis.
The study, published in Ecology and Evolution, shows climate change can create new biological interactions and reshape communities.
