On friday, we heard prairie warblers at a couple of spots in the Edge preserve. While they have been reported elsewhere, these were the first that I had heard this spring. Chris Bedel reported hearing an oven bird last week. A walk in the rain this morning revealed that few more of the migrant bird species have arrived! A singing hooded warbler, black and white warbler, and yellow throated vireo were the "new" birds for this spring. Oven birds were abundant.
