Weaver Wednesday 3: range changes in S Africa
Scaly-feathered Finch Sporopipes squamifrons
Range changes in SA
Range change summary
In South Africa the Scaly-feathered Finch has more grid cells with increases in reporting rate than cells showing decreases, between SABAP1 (1987-1991) and SABAP2 (2007-), although this is reversed when using 30 checklists for the analysis. The points below match the points on the map above.
Areas with very large increases include:
1. range expansion towards Pafuri (KNP), and breeding
2. range increases around Burgersfort
3. Northern Cape and western Free State show large or very large increases
4. Western parts of the Eastern Cape areas show large or very large increases
Large decreases appear to have occurred:
5. In Gauteng it has a very low reporting rate, probably due to decreases in size of suitable habitat patches
6. Large or very large decreases appear to have occurred over large areas of northern South Africa, probably related to habitat changes.
Range changes elsewhere
Angola: range extends further than mapped in (Fry 2004a) (in prep.).
Zimbabwe: range increasing around Bulawayo (Dean 1963a).
