Adjustment of incubation according to the threat posed: a further signal of enemy recognition in the Blackcap Sylvia atricapilla?

Original language description

Here we address the question of whether Blackcaps change their incubation behaviour in response to various nest intruders and whether this matches the intensity of mobbing. Near focal nests, we successively exposed a dummy of a brood parasite, nest predator and a control. After the parents had responded, we removed the dummy and filmed their incubation. The most aggressive response towards the Cuckoo and high nest attendance after its disappearance indicated recognition of the brood parasite. Low-intensity response to the Jay, together with reduced subsequent parental care, suggested that Blackcaps perceived it either as less deleterious at the egg stage than the Cuckoo or as a danger to themselves. Almost no aggression towards the Turtle Dove and theresumption of incubation after its removal, implied that Blackcaps recognised it as harmless. Our results demonstrate that the issue of enemy recognition may be viewed as a complex of both aggressive and postpresentation behaviours.
