Parents are always warning their kids about something or another; but do they warn them differently when danger is near? When researches played sounds of baby birds, the mother birds chirped in response and approached with various greetings. When a taxidermy predator was placed nearby, however, the parents approached the nest with a shrill buzz of alarm. Researchers have done behavioral testing like this before, but only primates. They suggest if this behavior exists in a bird species as well, it may be widespread, but further testing will be needed to confirm.
