The thing about parrots...

Abstract: Poaching for the pet bird trade is one of the main threats to wild parrots. Parrots in urban areas might be exempt from poaching because nests are likely inaccessible in the urban mosaic of public and private lands where the public and authorities keep more effective vigilance than in natural habitats. We report on the demographics and fate of a small population of exotic Scarlet Macaws (Ara macao) introduced into the urban area of Haarlem in The Netherlands in the 1970’s, which has a temperate, maritime climate, quite unlike the natural breeding area of the species. One breeding pair was reported, with successful breeding attempts in at least eight years between 1980 and 2009. A series of poaching events between 2005 and 2009 likely lead to the demise of the local nesting population of Scarlet Macaws.
