Another work trip, this time to Minnesota, gave me a chance to do some birding on a glorious Sunday. Quite a lot had gone south already, but there were hundreds of American Robins and Myrtle Warblers passing through, with flocks of Cedar Waxwings and Ruby-crowned Kinglets everywhere.
A Red-bellied Woodpecker was my 4000th world species, and back at the swamp by the hotel in the evening, I came across three Eastern Bluebirds, still hanging around in the north to add another lifer.
