A maneuverable canopy net for capturing large tropical birds

Abstract

Capturing birds of tropical rainforest canopies is important for answering many questions in ecology, evolution, and conservation, but canopy birds are often out of reach when using conventional mist-netting methods. Some methods exist to mist-net canopy birds, but modifications needed for target-capturing large frugivores are not well documented. Here, we describe a canopy netting method for capturing large, fruit-eating birds in rainforests. The methods presented here emphasize a large net area, maneuverability of netting, and collapsibility for safely preventing the escape of captured birds. During three different projects in the rainforests of Cameroon, this technique has resulted in the successful capture of hornbills (Bucerotidae), turacos (Musophagidae), and fruit pigeons (Columbidae). We recommend this technique for canopy bird research and encourage documentation of any modifications.
