| Summary: | Based on the database of 1986-2000 provided by the Wild Bird Federation Taiwan and a field assessment survey conducted between 1998 and 2000, four exotic species of cockatoos, belonging to the genus Cacatua (Psittacidae), were found in Taiwan. The Goffin’s Cockatoo (C. Goffini) and the Sulphur-crested Cockatoo (C. galerita) are more common than the White Cockatoo (C. Alba) and the Lesser Sulphur-crested Cockatoo (C. sulphurea). Most of the sightings were in single or small flocks occurring in or near metropolitan areas of western Taiwan. The birds built permanent roosting sites that were occupied by one to three species. The feral populations of the cockatoos in Taiwan have remained low but fairly stable, since they were introduced more than 20 years ago. Overall, they are not successful invaders. |
