The gradual loss and episodic creation of Palm Cockatoo ( Probosciger aterrimus ) nest-trees in a fire- and cyclone-prone habitat
We present information regarding the rate of loss of nest-hollows over a long period in the tropics, and a dramatic episode of nest-hollow creation following two tropical cyclones. We followed the fate of 61 Palm Cockatoo (Probosciger aterrimus) nest-trees over a period of 6 years (1999 to 2005). On average, 48 trees were monitored each year. During this time 16 (26.2%) were rendered unusable for Palm Cockatoos; their final cause of loss was fire (n = 10; 62.5%), wind (n = 4; 25%), and intense...[Show more]
