Early spring due to warming climate declining birds’ population, study finds
New Delhi, Jul 4 (PTI) Warming climate is making birds produce fewer off springs by advancing spring-like weather, and hence the birds’ breeding season, and the birds not being ready to reproduce, according to new research.
Suggesting that breeding productivity may decrease by about 12 per cent for the average songbird species, the research said that the mismatch between an early spring onset and the birds’ readiness to breed is likely to get worse as the world warms.
Birds produced fewer young if they started breeding too early or late into the season, the research led by scientists at University of California Los Angeles (UCLA) and Michigan State University, US, found.
