January 22, 2017 – Grey-headed Gull or Grey-hooded Gull (Larus cirrocephalus)
These gulls are found in parts of South America and sub-Saharan Africa. They eat mostly fish and invertebrates and scavenge dead fish and the eggs of flamingos, cormorants, and herons. Nesting in colonies of several pairs to hundreds of birds, they build shallow bowl-shaped nests on the ground from grass, twigs, and weeds, or floating platform nests from sedges and lily leaves. Both parents incubate the eggs and aggressively defend the chicks, which can run within a day of hatching.
