Sternula balaenarum
The Damara Tern (*Sternula balaenarum*) is a diminutive and elegant seabird, measuring approximately 20-23 cm in length with a wingspan of 45-50 cm and weighing a mere 40-60 grams, making it one of Africa's smallest terns. Its breeding plumage features a striking black cap extending below the eye, pale grey upperparts, pristine white underparts, a short black bill, and black legs, with a distinctive dark wedge visible on its outer primaries during flight. Non-breeding adults exhibit a white f...
This species primarily inhabits arid coastal environments, favoring exposed sandy beaches, shell-covered flats, salt pans, rocky islets, and the margins of estuaries and lagoons for breeding. It is strictly a sea-level bird, rarely found far from the immediate coastline.
The Damara Tern's diet consists almost exclusively of small pelagic fish, such as anchovies and sardines, which it procures through agile plunge-diving close to the water's surface. Occasionally, it may also consume marine invertebrates.
Damara Terns are diurnal birds, spending their days actively foraging and roosting communally on sandbanks or sheltered beaches during non-breeding periods. Their primary foraging strategy involves short, shallow plunge-dives from a low hover, snatching small fish from just below the water's surf...
