บทคัดย่อ
Survival of tropical passerines is thought to be higher than those in northern temperate regions, but relatively few tropical studies have addressed this issue, particularly in tropical Asia. We examined factors that may have influenced the survival rate of a cooperatively breeding bird, the puff-throated bulbul (Alophoixus pallidus), in an evergreen forest in northeastern Thailand. These factors included year, season (breeding and non-breeding), sex, and presence of helper(s) in a family group. We present evidence of breeding season-dependent survival in a tropical passerine using an information theoretic approach based on both mark-recapture and resighting data collected during 6 years of study. Based on colour-banded adults the annual survival rate did not vary significantly among years (average = 0.85 ฑ 0.02 SE). The mean lifespan (MLS) for the population was 6.22 ฑ 4.38 SE years. Survivorship was lower during the breeding season (0.89 ฑ 0.02 SE) than during the non-breeding season (0.96 ฑ 0.02 SE). The MLS of males and females was 6.70 ฑ 7.73 SE and 5.87 ฑ 4.88 SE years, respectively. The annual survival rate we observed was high compared to the estimates of other tropical and temperate passerines, possibly due to the relatively stable climatic conditions in tropical latitudes and puff-throated bulbuls being generalists that exploit a wide range of food resources both in space and time. ฉ 2011 The Ecological Society of Japan.
