Researchers: When mates are rare, birds help their parents raise more offspring
Male birds are more likely to do so: After a five-year experiment, researchers from Florida State University and the Tallahassee-based Tall Timbers Research Station found that when fewer mates were available for brown-headed nuthatches, these small pine-forest birds opted to stay home and help their parents or other adults raise their offspring… Associate Professor of Biological Science Emily DuVal and Jim Cox, a vertebrate ecologist from Tall Timbers and a courtesy faculty member at FSU, had long been interested in how these tiny birds showed cooperation—that is often having non-breeding young adults hang out and help raise chicks. After all, bypassing the chance to reproduce is not typically how nature works… This was the first large-scale, experimental evidence that the Read More ›
