ANGULO PRATOLONGO, Fernando. Dispersal, survival and reproduction of reintroduced white-winged guan Penelope albipennis Taczanowski, 1877 (Cracidae) to its natural habitat. Ecol. apl. [online]. 2004, vol.3, n.1-2, pp.112-117. ISSN 1726-2216.

The White-winged Guan (Penelope albipennis) is a cracid endemic to the Northwestern Peruvian dry forests that is critically endangered due to poaching pressure and habitat loss. In the year 2000, a species reintroduction program was established which consisted in the release of captive born and raised animals from the Barbara D’Achille captive breeding center. The guans were released in areas where the species had disappeared and that were safe for reintroduction and conservation. Between September 2001 and July 2003, 20 White-winged Guans were released at the Chaparrí Private Conservation Area, Lambayeque, Perú. The bird’s adaptation to the area was measured through its dispersion, survival and reproduction. Based on the measured dispersion distance, it has been found that it is actually feasible to link the reintroduced population with the surrounding wild populations. Survival has been established at 55 %, measured two years after the animals were released. With respect to reproduction, 3 wild-born chicks were born from reintroduced parents.
