Can migratory birds survive rapid climate change? The answer may be in their genes.
The team, led by University of California Los Angeles biologist Rachael Bay, crowdsourced blood and tissue samples from museum collections and researchers across the yellow warbler’s geographic range.
Their sample included a variety of habitats — marsh, forest, and urban areas — extending from California to northern Canada and Alaska. They analyzed DNA from the birds to see if connections already existed between their genetic traits and their environmental location.
