Flycatchers are members of a big North American bird family, 21 species, many relatives. If they had a reunion some probably would need name tags so they could tell one from another.
Identification for some of them can be challenging.
Minnesota has seven breeding flycatcher species. None are feeder birds, all are habitat-specific.
Great crested flycatchers, our bird of the day, prefer open deciduous woodlands and edges of clearings, according to its account in the "Birds of North America" pamphlet series.
Urban areas with large shade trees qualify, as do parks, cemeteries and perhaps your neighborhood.
If so, this flycatcher needs no name tag. It is particularly on the easy-ID side. You might puzzle a moment or two on plumage, but if you hear it there should be no question.
Great crested flycatchers do not sing. They yell, both sexes. They command attention. This is evident during nesting season, when the birds are looking for a mate — screaming for a mate.
David Allen Sibley is his identification book describes the "song" as queEEEP or KRREEEP, a long, loud, rising note. There are some softer notes, too, as Sibley says, "all often combined into excited series — KREEEP, KRREEP, kwip-kwip-kwip-kwip-kweep, krreep."
