I've had 2 yard sightings of a Cowbird in the past week:
A female was perched quietly on the corner of my roof, a place I rarely look, and I suspect she was looking for nesting behavior of other birds.
Perhaps the same female a different day was feeding on a neighbor's lawn near an adult Starling. I don't think this was a juvenile Cowbird following a foster parent.
