Non-Migrant: Yes. At least some populations of this species do not make significant seasonal migrations. Juvenile dispersal is not considered a migration.
Locally Migrant: Yes. At least some populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: Yes. At least some populations of this species make annual migrations of over 200 km.
Many stay close to nesting areas in winter. A portion of the eastern subspecies migrates to Florida, the Caribbean coasts of Colombia and Venezuela, and the Greater Antilles for winter. During cold winters, some Texas breeders winter along the Gulf Coast of Mexico. Individuals from breeding areas north of Florida winter mainly in Florida and Cuba; young and adults from Florida breeding colonies are more sedentary (young generally do not disperse more than 250 km from natal areas, adults may move up to 450-575 km from colony during the nonbreeding season) (Johnsgard 1993).
