Local movements and translocation experiments of resident and migratory birds in southern Veracruz, Mexico
Published online by Cambridge University Press: 11 May 2010
Summary
A total of 114 individuals of 17 resident and 10 migrant species captured at a rainforest study site in the Tuxtla Mountains of southern Veracruz, Mexico, were displaced to a second rainforest site 2.5 km distant. Return rates to point of capture were high for both groups (73% for resident species versus 74% for migrants). These comparable rates, when considered with evidence that residents can accumulate large fat reserves, indicate that resident species possess key adaptations necessary for migratory movement.
Un total de 114 individuos pertenecientes a 17 especies residentes y 10 migradoras capturados en un enclave de selva húmeda en las montañas de Tuxtla al sur de Veracruz, México, fueron trasladados a un segundo enclave de selva humeda situado a 2.5 km de distancia. Las tasas de retorno al punto de captura fueron altas para los dos grupos (73% para las especies residentes y 74% para las migradoras). Teniendo en cuenta que los residentes pueden acumular grandes reservas de grasa, la similitud de estos resultados indica que estas especies poseen las adaptaciones necesarias para el movimiento migfatorio.
