‘Mum! I’m hungry!’ Hungry chicks have unique calls to their parents

26 01 2011

Scientists studying Jackson’s Golden-Backed Weaver birds have discovered that not only can the parent birds identify their own chicks by the unique sound of their calls, but they can also tell if their chick is hungry, and how hungry.

A press release that I wrote for BioMed Central, following a study published in BMC Ecology, reveals that the more hungry a baby bird is, the more frenetic and unique the call becomes, so that parent birds not only know that they need to gather food for their young, but also how much.
