Groups and Breeding
These birds live in pairs or very small groups, however in times of plentiful fruit they can congregate in large groups on the best fruit trees, and occasionally when numerous birds find the same good roosting areas, which are always in the tallest of trees in the area.  The female will lay 2 eggs, occasionally up to 3 which take around 28 days to incubate.
