Climate change is making it harder for some animal species to survive as weather patterns become more extreme.
Researchers at UC Davis took 11 years of data to study how spring rainfall and temperatures are affecting songbirds in the Central Valley and their ability to reproduce.
Jason Riggio, UC Davis Museum of Wildlife and Fish Biology post doctorate scholar, co-authored the study. Riggio says, “We’re looking at potentially a 30% reduction in reproductive success in fledglings that reproduce when we’re seeing the hottest temperatures compared to the cooler temperatures. And that’s for birds like tree swallows and western bluebirds that are already near or at their hottest temperatures that
