Gambel’s White-crowned Sparrow

On Tuesday, I found sparrows in a large brush pile in Carleton College’s arboretum. Most of the birds were White-crowned Sparrows. This male  can be identified as the Gambel’s race of the species, known by its gray lores. Black-lored birds are the eastern, nominate (first described) subspecies of the bird (which also migrates across Minnesota). In 2009, I blogged about a few of these races and how to tell them apart. I was surpised that eBird flagged Gambel’s White-crowned Sparrows as being rare in Northfield.
