Post-Fledgling Survival of the Cooperatively Breeding Puff-Throated Bulbul (Alophoixus Pallidus)

摘要: Abstract. In the tropics, passerines are expected to have survival rates higher than those in temperate zones, though their post-fledging has rarely been quantified. Furthermore, because of increased care by adults, cooperative breeding species should even juvenile survival, but few data available on such also. Over three seasons we examined factors relating cooperatively Puff-throated Bulbul (Alophoixus pallidus) an evergreen forest northeastern Thailand. These included presence helpers, fledgling age, sex, body mass prior fledging, date fledging within a year, and variation year. The probability surviving 8-week period dependency was 0.61 ± 0.09 (SE), most reports from zone. Survival strongly associated with age not helpers. Weekly lowest during first week (0.73 0.08), wh...
