Survival among Birds of the Understorey in Lowland Rainforest in Papua New Guinea

Recapture rates of birds netted at Brown River, Papua New Guinea are analysed. Newly-banded birds have a much lower recapture rate than birds banded one year or more. Recapture rate of newly-banded birds is lowest in those with high breeding success and large clutches (mostly hole-nesters) and highest in those with low breeding success and small clutches (mostly open-nesters). Nectarivores appear to be as sedentary and longlived as insectivores. Survival rate increases in the second year from banding and drops after the fifth or sixth year. Rate of recruitment is estimated at 10-20% annually. The results are similar to that for other tropical forest areas.
