Habitat of the American Little Tern
Geographic range
The American Little Tern is native to North America and occurs along the coastal areas of the Atlantic Ocean, the Gulf of Mexico and the western coast of the United States.
Preferred habitat
This tern prefers shallow coastal waters, estuaries, marshes and lagoons, where food is readily available and safe nesting sites can be found.
Migratory behavior and breeding areas
During the breeding season, American Dwarf terns seek quiet places on pebble beaches or sandy islands to build their nests, such as the uninhabited island of Klein Curacao. After the breeding season, some populations migrate to wintering grounds in Central and South America.
Threats to habitat
The destruction and disturbance of coastal areas by human activities, such as coastal development, habitat loss and pollution, pose serious threats to the habitat of the American Little Tern.

Life Cycle and Behavior
The behavior
The behavior of the American Little Tern is fascinating. They are known for their spectacular aerial diving flights, deftly grabbing fish from the water. These birds are highly social and form colonies in which they breed and forage together. As a breeding bird, they fiercely defend their territory against intruders and form close pairs.
Breeding season and nest building
The breeding season begins in spring, during which the American Little Tern often forms colonies. They dig shallow pits in the sand and lay their eggs there, usually one to three per clutch. Both parents actively participate in incubating the eggs and feeding the young after they hatch.
Reproductive behavior and mating rituals
They are monogamous birds, meaning they usually choose a single mate each breeding season. Upon arrival in their breeding grounds, they begin performing impressive mating rituals to strengthen the bond between partners. The mating rituals of the American Little Tern are a mesmerizing sight to behold. The male often begins with an exuberant flight in which he performs artful dives while emitting loud cries to attract the female’s attention. Once interested, the female performs a graceful dance, fluttering her wings and moving gracefully through the air. This joint dance helps strengthen the mutual bond and promote a relationship of trust between partners.
Migratory patterns and wintering areas
After the breeding season, some populations leave their breeding grounds and migrate to warmer wintering areas in Central and South America.
