Abstract:Territories of the chaffinch (Fringilla coelebs) and great tit (Parus major) overlap on the mainland of Scotland but are mutually exclusive on adjacent islands. Birds on the mainland responded only to playbacks of conspecific song. On the island both species responded to conspecific song and non-conspecific song, but not to the song of the willow warbler. On the island, great tits responded significantly more strongly to songs than did the chaffinches. When chaffinches were removed from part of the island woodland, great tits rapidly expanded into the vacated areas. It is suggested that on the island there is a limit to the co-existence of these two species because they forage in a similar manner and that this has resulted in interspecific territoriality, not seen on the richer mainland environment.
