AVIAN BROOD PARASITISM


Cowbirds use a breeding system known as Brood Parasitism. The female Cowbird lays her eggs in the nests of other birds.
The nest owners, called hosts, will become responsible for the parasite's egg and young.
Cowbirds never build a nest and depend solely on the nests of other species.

While it is a fairly common sight to see many backyard birds feeding and parenting young cowbirds,
I was a bit surprised and amused when I came upon this male Scarlet Tanager hosting a cowbird chick.
"Dad" seems to be offering a beetle to Junior, but Junior is more interested in playing with a Harvestman.
