Abstract
Summary. Oscine passerine birds learn their songs principally through cultural transmission. However, habitat fragmentation might induce cultural variation in song, leading to restrictions in the transmission of cultural information. In this study, we aim to evaluate individual responsiveness to conspecific vocalisations within and between two nearby bird populations to assess within-species behavioural changes with distance. To do so, we used song playbacks of'Elepaio Chasiempis sandwichensis in a fragmented landscape on the north-east slope of Mauna Loa Volcano (Hawaii Island, USA). We evaluated the response of'Elepaio males to songs recorded in their own populations and to those recorded in another population. We also compared vocalisations between both populations to assess acoustic differentiation. Our results indicate behavioural divergence in song responsiveness over a small spatial scale for this species as well as significant differences in acoustic traits. However, contrary to what was expected,'Elepaio individuals from both populations did not vary in their response pattern to songs depending on their origin. This suggests that acoustic differentiation may not be strong enough to drive behavioural divergence in response of'Elepaio individuals despite the existence of differences in the acoustic traits between both populations.—Oñate-Casado, J., Sebastián-González, E. & Hart, P.J.

期刊介绍:
Ardeola: International Journal of Ornithology is the scientific journal of SEO/BirdLife, the Spanish Ornithological Society. The journal had a regional focus when it was first published, in 1954. Since then, and particular during the past two decades, the journal has expanded its thematic and geographical scope. It is now a fully international forum for research on all aspects of ornithology. We thus welcome studies within the fields of basic biology, ecology, behaviour, conservation and biogeography, especially those arising from hypothesis-based research. Although we have a long publication history of Mediterranean and Neotropical studies, we accept papers on investigations worldwide.
Each volume of Ardeola has two parts, published annually in January and July. The main body of each issue comprises full-length original articles (Papersand Review articles) and shorter notes on methodology or stimulating findings (Short Communications). The publication language is English, with summaries, figure legends and table captions also in Spanish. Ardeolaalso publishes critical Book Reviewsand PhD-Dissertation Summaries; summarising ornithological theses defended in Spain. Finally there are two Spanish-language sections, Ornithological News; summarising significant recent observations of birds in Spain, and Observations of Rare Birds in Spain, the annual reports of the Spanish Rarities Committee.
