Range Description

Heteromirafra ruddi is an endemic resident of east South Africa. Although records are spread over a large area, its distribution within this area is patchy. The core of its restricted range is centred on south-east Mpumalanga, north-west KwaZulu-Natal and the north-east Free State. Small, isolated populations are found farther north in the Dullstroom-Machadodorp district, farther south at Matatiele in west KwaZulu-Natal, and at Ncora Dam and Molteno in the Eastern Cape. The overall population was not thought to have decreased significantly since the mid-1990s (P. Ryan in litt. 2005), however its absence has been noted at former strongholds, suggesting it is now in decline (D. Maphisa in litt. 2007), and comparison of data in South African Bird Atlas Project 1 and 2 indicates a reduction in area of occupancy of over 50% (D. Maphisa in litt. 2012). Specimens from Warden in the Free State and sight records from the Memel-Vrede-Warden-Harrismith arc suggest that there may be a substantial, previously overlooked, population in the eastern Free State. The global population has been estimated at 1,500-5,000 individuals (Siegfried 1992). A lower limit of 2,500 individuals has been suggested as more realistic (Barnes and Tarboton 1998), but it has been suggested that the lack of new sites and disappearance from former strongholds mean the total population may be much lower (D. Maphisa in litt. 2012).
