Survival and site fidelity study of rehabilitated and released black and white laughingthrushes (Garrulax bicolor) within In-situ conservation program

By Tomáš Bušina


Indonesia, as many other equatorial tropic countries, is facing massive deforestation and environment degradation owing to the intense agricultural development during last decades. Habitat loss and widespread illegal animal trade are major causes of population decline of a number of animal species, primarily birds nowadays. According to BirdLife International, Indonesia ranks second place among the countries with the highest number of globally threatened bird species, with a total number of 132 species. On the other hand, new conservation activities and programs that use reintroduction tools are arising there. The success of such programs however, depends on bionomics knowledge of target species followed by suitably adjusted program management. One of these threatened but poorly known bird species of Indonesian avifauna is Sumatran laughingthrsuh (Garrulax bicolor), endemic to Sumatra Island. There are only two established programs engaged in its protection throughout Indonesia. Unfortunately, due to the lack of biological and ecological data of target species, no reintroduction plan was developed yet. Therefore, this study aims at enhancing current knowledge on Sumatran laughingthruses by examining mortality of rehabilitated and experimentally released individual birds by using radio-telemetry method. Furthermore, assess their post-release behaviour, mainly pair bond strength and release site fidelity. This study also includes long-term bird market monitoring, which will enable to estimate an amount of harvested birds and its impact on remaining wild populations. All gained results should allow to suggest appropriate conservation plan for target species and in addition supplement missing information in literature
