Vesper Sparrow

Two Wednesday’s ago, John Holden and I found a flock of about a half-dozen Vesper Sparrows. The birds fed along the roadside near Circle Lake here in Rice County. Vesper Sparrows are abundant field birds here in Northfield, and I have posted on the species in this blog. Field marks include the dark cheeks, which contrast with the white eye ring. Especially in flight, the white outer tail feathers are apparent. Not so evident in this photo is the Vesper Sparrow’s chestnut shoulder. Early ornithologists referred to the bird as the Bay-winged Sparrow.
