Little Blue Heron The Little Blue Heron (Egretta caerulea) is a small heron. It breeds in the Gulf States of the US, through Central America and the Caribbean south to Peru and Uruguay. It is a resident breeder in most of its range, but some northern breeders migrate to the Southeastern US or beyond in winter. There is post-breeding dispersal to well north of the nesting range, as far as the Canada–US border.
