Black & Common Terns at El Guayabo Wetlands

During an April 9, 2011 visit to the El Guayabo wetlands north of Granada, Manfred Bienert observed half a dozen Black Terns (Chlidonias niger) and 30-40 Common Terns (Sterna hirundo).

Manfred also reports seeing several large groups of Pectoral Sandpiper (Calidris melanotos), including one pair that appeared to be engaging in a courtship ritual, which Manfred believes could be evidence that this species is forming mating pairs here in Nicaragua before migrating north to its breeding grounds.
