Název v původním jazyce

Importance of competition for food and nest-sites in aggressive behaviour of Collared Flycatcher Ficedula albicollis

Popis výsledku v původním jazyce

Capsule Using an experimental approach, this study disentangles effects of two important sources on the elicitation of aggressive interspecific behaviour. Aims To investigate experimentally whether competition for nest cavities and/or food can explain aggressive behaviour between competing species.Methods The Collared Flycatcher's Ficedula albicollis responses to mounts of Great Tit Parus major (nest-site and food competitor), Chaffinch Fringillo coelebs (food competitor) and Dunnock Prunella modularis(control species) were tested. Trials were performed near flycatchers' nests during nest building, incubation and care of nestlings.Results The intensity of dive attacks and frequency of contact attacks showed that the aggression of Collared Flycatchersdecreased in the direction: Great Tit > Chaffinch > Dunnock. The difference in aggressiveness was greater between Great Tit and Chaffinch than between Chaffinch and Dunnock. Aggression directed toward Great Tits increased from the nest bu
