Red winged blackbirds seen at Coventry Lake

The redwing blackbird is a common sight at PA waterways.  The blackbird is black with a reddish orange blotch on them.  The reddish orange blotch has a yellow patch surrounding it.  The male blackbird's social status depends on how much red he has on his wings.  The one with the most red has the most power in their social network.  They are often seen perching on cattails or on trees in the water.  The picture of the blackbird is courtesy of google images.
