There were 126 General Notes published in The Auk in 1921. Of those, only 23% dealt with something other than distribution. Natural history notes with personal stories often accompanied distributional lists of birds. Otherwise, there were reports of behavior (17), including subjects of song, foraging, nesting, and nest parasitism. There were mentions of elements of natural and anthropogenically driven mortality (3). A few reports concerned nomenclature and systematics (8), and less than a handful directly concerned plumage (4). Overall, reports from East of the Mississippi predominated (83). Twenty-four were from the West, 12 from Canada, and 7 either pertained to or came from overseas.
