Song / call of Black-headed Gull Bird

Black Headed Gull Bird 2

Black-headed bird is very vocal, particularly around breeding colonies, where the noise can be deafening and often continues through the night. It has a variety of rather unattractive harsh calls, the common call being a slurred screech, "krreearr" or "kaa'aarrr". It gives a harsher and insistent "raaargh!" or "gaaarhh!" when reacting anxiously to the presence of intruders, but also has a softer and less urgent "aaarrrr", an "akh'akh'akh" and singles and multiples of "kik", delivered in a more conversational tone. A longer and more elaborate call, "kre-kre-kreh'kraaa'kraaaa'kraaaa'kraaaa", is given in various social contexts.
