In this paper it was explored the escape and nest defence behaviours in Larus cachinnans Pallas, 1811 (Colony of Isola Piana, Sardinia - Italy) reacting to the presence of a human intruder. Each of the six selected subjects (from different nests) was approached by a human intruder (one of the experimenters) six times during each of the two periods (25 days after eggs laied and chicks 3-5 days aged). Alarm, escape from the nest, fly, landing, return to the nest have been mesured. During incubation periods all the animals showed the same behaviour. Aggression and next defence increase during hatching period.

Abstract

In this paper it was explored the escape and nest defence behaviours in Larus cachinnans Pallas, 1811 (Colony of Isola Piana, Sardinia - Italy) reacting to the presence of a human intruder.

Alarm, escape from the nest, fly, landing, return to the nest have been mesured. During incubation periods all the animals showed the same behaviour. Aggression and next defence increase during hatching period.
