In South Africa the Long-tailed Widowbird has more grid cells with decreases in reporting rate than cells showing increases, between SABAP1 (1987-1991) and SABAP2 (2007-).

The points below match the points on the map above.

Areas with increases include:
1. Central highveld.

Areas with very large decreases include:
2. Many edges of its range in South Africa show decreases, especially KwaZulu-Natal.
3. Humansdorp area - a small population persists - it has been present historically, and initially must have been joined to the rest of the South African population.

Range changes elsewhere

None known.

In South Africa the Fan-tailed Widowbird has more grid cells with increases in reporting rate than cells showing decreases, between SABAP1 (1987-1991) and SABAP2 (2007-).

The points below match the points on the map above.

Areas with very large increases include:
1. Gauteng, western Mpumalanga and eastern Free State - there has been a range expansion into these areas since SABAP1, probably due to higher rainfall.

Areas with very large decreases include:
2. Northern parts of the Eastern Cape, although the reporting rate here is low.

Areas with small changes include:
3. KwaZulu-Natal - this is the core of its range in South Africa, and its population appears to be fairly stable here.

Range changes elsewhere

Mozambique: increasing on Inhaca Island (de Boer 1999a).

In South Africa the White-winged Widowbird has slightly more grid cells with increases in reporting rate than cells showing decreases, between SABAP1 (1987-1991) and SABAP2 (2007-).

The points below match the points on the map above.

Areas with very large increases include:
1. SW Mpumalanga and much of Free State - there has been a range expansion into these areas since SABAP1 due to higher rainfall.
2. Eastern Cape - scattered records of small wandering flocks.

Areas with very large decreases include:
3. Along the Limpopo River/Botswana border.
4. Most of KwaZulu-Natal.

In South Africa the Red-collared Widowbird has slightly more grid cells with increases in reporting rate than cells showing decreases, between SABAP1 (1987-1991) and SABAP2 (2007-).

The points below match the points on the map above.

1. The core range of this widowbird in South Africa lies from eastern Mpumalanga to southern KwaZulu-Natal, excluding Zululand (this core has high reporting rates in SABAP2)
2. The Eastern Cape overall has slightly more decreases than increases between SABAP1 and SABAP2.

Overall the Red-collared Widowbird shows a fairly stable population between SABAP1 and SABAP2. There are many grids with large or small changes, but these are fairly patchy.

Range changes elsewhere

No major range changes known elsewhere, but it may wander in response to rainfall, eg. recorded 170km west of its known range at Selukwe, Zimbabwe, probably due to rainfall (Donnelly 1973a).
