| Descripción: | The expansion of human settlements has produced significant changes in natural ecosystems by fragmenting and reducing their area. Those changes influence the availability of natural and artificial sites used to build nests by birds. Some species nest on perches built by humans, but the characteristics of the perches that are selected are unknown. Our goal was to analyze how characteristics of utility poles and their proximity to human buildings and forest patches influence the presence of Great Kiskadee (Pitangus sulphuratus) nests. We count-ed and described all the poles present along 30 km of gravel and asphalt roads in Rincón de Osa, Costa Rica. We classified each pole accord-ing to the number of metal plates, electrical transformers, and lights. We also recorded whether the pole had a Great Kiskadee nest. We measured the distance of each pole with a nest to the nearest human building and forest patch. Nests were more frequent on poles far from forests and near buildings. The characteristics of the poles also influenced the presence of Great Kiskadee nests, possibly due to the lower risk of predation that the structure provides, because there was a greater probability of finding nests on poles with an electric transformer than on poles with wires only. We found that both, perch structure and distance to buildings and forest patches, influence where the Great Kiskadee builds its nests. |
