Birding Angola BREAKING NEW GROUND n the decade since the civil war in Angola came to an end, the face of the country has changed unrecognisably. now the Ilargest oil extractor in Africa, the nation is experiencing great wealth and unimaginable infrastructure developments to feed this insatiable industry. The focus is on much-needed economic growth, and environment issues have, understandably, taken a back seat. But this may be changing: Angola’s reserve network has been reviewed in recent months and plans for its expansion approved. There is still a long way to go before all the country’s birds are adequately protected, but at least the importance of doing so is now being recognised.

However, the steeply rising scarp trapped moisture the mountains and scarp in the west, from the nearby Atlantic Ocean, allowing pockets of dry forest to persist on it even which together form the core of the when, at the driest times, the surrounding areas were covered in arid savanna. Western Angola Endemic Bird Area With hundreds of kilometres separat- ing the pockets of scarp forest from the nearest similar vegetation, some resident birds evolved in isolation, slowly chang- ing into unique, endemic species. As the area has become moister in recent times, these dry forests and thickets appear to have spread into adjacent areas along the coastal plain, with the result that species that may have evolved in them, such as Red-backed Mousebird, Pale-billed Fire- finch, White-fronted Wattle-eye, Angola Batis, Golden-backed Bishop and Pale- olive Greenbul, are now more wide- spread. Among the true forest endemics are the striking Red-crested Turaco, the secretive Grey-striped Francolin, the un- obtrusive Gabela Akalat, two dull forest warblers (Pulitzer’s Longbill and Hartert’s Camaroptera) and a quartet of impressive bush- and helmet-shrikes (Gabela, Braun’s and Monteiro’s bush-shrikes and Gabela Helmet-Shrike).
