We documented movement of a long-distant migrant (Swainson's Thrush Catharus ustulatus) and two understory resident species (Chestnut-capped Brush-finch Buarremon brunneinuchus and Streak-capped Treehunter Thripadectes virgaticeps) in a fragmented landscape dominated by a pasture matrix in a SubAndean region of central Colombia. Swainson's Thrush had no detectable difficulties traversing a pasture matrix and returning to the capture site. Chestnut-capped Brush-finch and Streak-capped Treehunter (understory resident species) avoided making lengthy flights and used stepping-stones and nearby corridors to ease their movement. Providing stepping stones such as live fences and isolated trees and maintaining corridors can enhance functional connectivity in regions with fragmented forests, aiding the conservation of bird species.Key words: Colombia, forest fragmentation, landscape matrix, land-use change, radio-telemetry Resumen Documentamos el movimiento de un migrante de larga distancia (Catharus ustulatus) y dos especies residentes de sotobosque (Buarremon brunneinuchus y Thripadectes virgaticeps) en un paisaje fragmentado dominado por una matriz de pastos en la región subandina del centro de Colombia. Catharus ustulatus no tuvo ninguna dificultad detectable en atravesar la matriz de pastos y regresó al sitio de captura. Por otro lado, B. brunneinuchus y T. virgaticeps (las especies residentes de sotobosque) evitaron hacer vuelos prolongados y utilizaron árboles aislados y corredores cercanos para facilitar su movimiento. Implementación de pasaderas como cercas vivas y árboles aislados, y el mantenimiento de corredores puede contribuir a la conservación de aves mediante la mejora de la conectividad funcional en regiones con bosques fragmentados.Palabras clave: Colombia, fragmentación de bosque, matriz del paisaje, uso de suelo, radio-telemetría Mongabay
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
