This is my contribution to the A Photo a Week Challenge: Brown.
This is a male Brown-headed Cowbird feeding on the South Bruce Peninsula, Ontario in the spring.
The common English name for the species comes from the male who has an iridescent black body and a brown head and for the species habit of foraging on the ground following grazing species such as cattle. The grazing animals disturb insects which are caught by the birds.
The species is a brood parasite, the females lay their eggs in the nests of other species. These species can be as wide ranging as Hummingbirds to Raptors.
