An example of the good work that Bird Studies Canada is doing at the Long Point Banding Station. Here a bander is holding a Lincoln's Sparrow - the netting is checked every 15min for new birds. Taken at Long Point, Ontario, Canada.
Being out of my element in Vancouver, I could not 100% identify this bird. Although my guess is a Swamp Sparrow, Natl Geographic field guide says it's rare out west. My next guess would have been Lincoln's Sparrow. Any ideas?
