Abstract
Various factors, including, weather, time, vegetation, and playback are known to affect bird capture efficiency using mist-net. Factors affecting bird capture were analyzed using capture data from the Japan-Russia Bird Banding Expedition in Sakhalin Island (1999～2003). Playback was effective for Rufous-tailed Robin, Siberian Rubythroat, and Black-faced Bunting. At least 80% of the banded birds of Siberian Rubythroat and Rufous-tailed Robin were captured before 6:00 AM. Both species were very active just before dawn. Black-faced Bunting was mainly captured after 5:00 AM. Large numbers of birds were captured when the rain stopped and the weather had changed for the better.
