Raptor of the Week: Merlin

Falco columbarius

The midsize merlin is a rare migrant and a rare winter resident, first occurring during migration in late March and again in late August. A few very old nesting records exist. Two subspecies of this falcon occur in Iowa: the taiga merlin and the Richardson's or prairie merlin, a pale form.
