Description: We studied the intra- and interspecific responses to playback of pre-recorded calls by five tropical humid forest owl species at La Selva preserve in northeastern Costa Rica from April to September 1995. Response to conspecific broadcast calls differed among species (X² = 24.4; df = 1; P < 0.001): Vermiculated Screech-owls (Otus guatemalae) responded to 47.6 per cent of broadcasts, followed by Crested Owls (Lophostrix cristata, 45 percent), Mottled Owls (Ciccaba virgata, 18.3 per cent), and Black-and-white Owls (C. nigrolineata, 9 percent). Crested Owls (x = 16.37, sd = 2.6), Mottled Owls (x = 11.7, sd = 7.1), and Vermiculated Screech-owls (x = 10.9, sd = 0.9) responded to interspecific playback more than did Black-and-white Owls (x = 2.04, sd = 2) (H = 10.6; P = 0.01). Spectacled Owls (Pulsatrix perspicilata) did not respond at all during our broadcasting period. Both types of response showed some monthly variation. Response to the calling of other owls also depended on ecological variables such as habitat selection, population density, and resource use. Our data suggest that the development of relationships within the tropical owl community at La Selva may have been mediated in part by intra- and interspecific calling.
