horizontal deployment, mist nets, canopy, understory, migrating neotropical songbirds, North America
A useful method is reported for deploying mist nets horizontally from canopy platforms. In a preliminary study of migrant birds in a central Massachusetts forest, more individual birds were netted in the canopy than in the understory during the autumn migration, and the species captured also differed by height. In a previous study without nets, some winter residents also showed height preferences for high vs. low bird feeders. The mist netting technique allows direct comparison of bird abundance in vertical strata with minimal disturbance to vegetation.
