Do Palm Cockatoos (Probosciger aterrimus) have long enough lifespans to support their low reproductive success?
Heinsohn, Robert; Zeriga, Tanya; Murphy, Stephen; Igag, P.; Legge, Sarah; Mack, Andrew L.
As an order, Parrots (Psittaciformes) are both the longest lived birds and among the most endangered. Palm Cockatoos (Probosciger aterrimus) have an extremely slow life history, including one of the lowest rates of breeding success reported for parrots. Here we use population viability analysis (PVA) to examine whether populations of Palm Cockatoos are viable in the long term with such low rates of reproduction. We built PVA models for two field sites with robust data on reproductive success...[Show more]
