ABSTRACT = {One of the most beneficial effects of foraging in group for animals is enhancement of predation avoidance. Habitat type and group size are known to affect foraging and vigilance behaviors of the animals. We video-filmed and analyzed foraging, vigilance and moving behaviors of 127 focal Red Collared Doves (Streptopelia tranquebarica) in the western Taiwan to determine the effects of habitat types (open and obstructed) and group sizes (1 to 27 doves) on the behaviors. The results showed that the total foraging duration (sec) and number of pecking increased with the increase in group size at both habitats, while the total vigilance duration (sec), number of scanning bouts and scan duration were higher at the obstructed habitat than those at the open habitat. The group-size effect on vigilance was found only at the obstructed habitat but not at the open habitat. However, the low potential predation threats and possible use of peripheral vision to detect predators might dismiss the group-size effect. Also, the total moving duration (sec) decreased with the increase in group size, an indication of increasing foraging efficiency and anti-predatory benefits.},
