One Species Caring for Another

Written by Conor Gearin

This is BirdNote. 

In North America, the European Starling has gained a bad reputation for competing with native bird species for nest cavities. They’re not known as good neighbors, to say the least.

But researchers in Ontario, Canada, were surprised to see three Hairy Woodpecker nestlings receiving care from both a female Hairy Woodpecker and a European Starling — a stunning example of a bird caring for another species’ young.

While the Hairy Woodpecker fed the chicks more times per hour than the starling, the starling made an effort to clean the nest cavity of waste, which the woodpecker did not do.

The researchers aren’t certain why the starling began caring for the woodpecker nestlings. Possibly, the woodpecker’s mate died and the starling’s strong parental instincts led the bird to start bringing food to the unrelated chicks. 

So begging calls from nestlings seem to work beyond a birds’ own species. While one species caring for another is rare among birds, the fact that it does sometimes happen shows just how powerful the sound of a begging chick is to an adult bird.
