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.
