| contents | Efficiency of playback for assessing the occurrence of five bird species in Brazilian Atlantic Forest fragments Danilo Boscolo Jean Paul Metzger Jacques M.E. Vielliard Multidisciplinaria (Ciencias Naturales y Exactas) birds playback Atlantic forest São Paulo State forest fragments Playback of bird songs is a useful technique for species detection; however, this method is usually not standardized.We tested playback efficiency for five Atlantic Forest birds (White-browed Warbler Basileuterusleucoblepharus, Giant Antshrike Batara cinerea, Swallow-tailed Manakin Chiroxiphia caudata, WhiteshoulderedFire-eye Pyriglena leucoptera and Surucua Trogon Trogon surrucura) for different time of theday, season of the year and species abundance at the Morro Grande Forest Reserve (South-eastern Brazil)and at thirteen forest fragments in a nearby landscape. Vocalizations were broadcasted monthly at sunrise,noon and sunset, during one year. For B. leucoblepharus, C. caudata and T. surrucura, sunrise and noonwere more efficient than sunset. Batara cinerea presented higher efficiency from July to October. Playbackexpanded the favourable period for avifaunal surveys in tropical forest, usually restricted to early morning inthe breeding season. The playback was efficient in detecting the presence of all species when the abundancewas not too low. But only B. leucoblepharus and T. surrucura showed abundance values significantly relatedto this efficiency. The present study provided a precise indication of the best daily and seasonal periods anda confidence interval to maximize the efficiency of playback to detect the occurrence of these forest species. 2006 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32778403 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.4 Vol.78 |
