Then there is the introduction of alien trees, which has led to the demise of many splendid tracts of fynbos but appears also to have permitted the steady westward encroachment of a number of species more characteristic of the moister, more wooded east. In the past two decades several forest raptors, such as Forest Buzzard and Black Sparrowhawk, have found new breeding habitat here. Thus too have the Acacia Pied Barbet (with its brood parasite, the Lesser Honeyguide, hot on its tail) and Red-eyed Dove been lured to the Atlantic shoreline. The most conspicuous recent arrival has been that of the raucous Hadeda Ibis, almost unknown on the Peninsula just ten years ago but now a familiar sight and sound in Cape Town’s suburbs.
