Brown Thrasher

On Monday we banded a young Brown Thrasher at our Dundas station. This event was somewhat surprising, since this year we had no visual evidence of thrashers. The black background of this photo is due to using a flash in the very early morning.

These thrashers usually nests in low trees of shrubs, and occasionally on the ground.  Both sexes tend to the eggs and young.  The hatchlings leave the nest quickly, sometimes within nine days. Brown Thrashers are the most common host for Brown-headed Cowbirds, despite often rejecting cowbird eggs (Cavit and Hass 2000).
