Orange Beach, Ala. — (OBA) —  The City of Orange Beach reports that Least Terns have entered their active nesting season along local beaches. The small shorebirds are beginning courtship and nesting behaviors that will continue through the summer. Officials say residents and visitors may notice increased activity along the beaches. The birds rely on these habitats to reproduce and raise their young.

The Least Tern, named for its size, is the smallest tern species in North America and one of the smallest worldwide. Weighing just one to two ounces—similar to a mockingbird—it is much smaller than common local species like the Royal or Caspian Tern. In ornithology, "Least" often denotes the smallest member of a bird family or genus.

According to the City of Orange Beach, the nesting cycle begins in early May with courtship behavior known as the “fish dance.” During this stage, male birds present fish to attract a mate. Once paired, the birds prepare nesting sites in the sand.

The birds build shallow nests called scrapes, where eggs are laid and incubated for about 21 days. Both parents share responsibility for keeping the eggs protected and cool. After hatching, the chicks remain flightless and vulnerable for another 21 days.

City officials say the young birds need about three weeks to develop flight feathers and become independent. During this period, chicks are often difficult to spot because of natural camouflage, increasing the risk of accidental disturbance.

The City of Orange Beach has partnered with the National Audubon Society, NOAA Restore Science Program, Virginia Tech Fish and Wildlife Conservation Program, Alabama Audubon, and the Alabama Department of Conservation and Natural Resources for nearly a decade. These partnerships support conservation and educational efforts.

The city’s Coastal Stewardship Coordinator is installing signage throughout public beaches. The signs are designed to inform residents and visitors about nesting activity and how to avoid disturbing birds, eggs, and chicks.

Officials say protecting Least Terns requires cooperation from the community and multiple city departments. Beachgoers are asked to give nesting areas space and to remain alert for marked zones and wildlife activity.

The City of Orange Beach encourages the public to be mindful when visiting the beach during nesting season. Maintaining a safe distance from birds and watching for camouflaged nests can help protect the species during this critical period.
