Examples Nocturnal
1. Belize March 26, 2001 (MO). "Wseew" call from perched bird with Spot-breasted Wren singing in the background.
Similar species "Wseew" call very similar to some variations of Acadian Flycatcher's "pseet" but is typically higher, less rising, and less emphatic. May be some overlap. See Vermilion Flycatcher.
Behavior Primarily a nocturnal migrant but engages in redetermined migration. Gives "wseew" call commonly on the wintering grounds but less frequently at other seasons. Not known to call in nocturnal migration but presumed to do so occasionally based on the behavior of Least Flycatcher.
