• Resumen

  • Parental feeding patterns and the interactions among nestlings are of great importance in any study of the parent-offspring relationship in altricial birds. Video-recording provides a useful tool for recording this behaviour at the nest. Here, we describe a bracket for holding a video- recorder, successfully used in a study with the Azure-winged Magpie Cyanopica cyanus nesting in trees. The bracket did not seem to have any negative effects on the birds, as no differences were detected in chick development or predation rates between nests in which the device was, or was not, used.
