Onychognathus nabouroup, a near endemic to Southern Africa, live in rocky hills or valleys, where they roost and breed. They enter towns for food, but generally avoid man- modified areas (Craig, Hulley 1992, reference in Hockey et al. 2005).

Starlings are more used to human presence and even feed regularily on human food at the campsites, the birds in our area are completely wild and very shy, if investigative.

When we are ringing birds we quite often can observe a couple or a small group of Pale-winged Starlings land on the trees at the waterholes, but rarely they get caught in the nets, they just observe, discuss and fly away, as also Rosy-faced Lovebirds

As far as I know, a nest in a tree has not been described, although it might have been well observed. Tarboton (2001) says, the Pale winged Starling "breeds in semi-arid and arid shrubland (Karoo) and savanna, either associated with cliffs and other rocky habitats (especially mountainous country) or, less often with cities, towns and villages. The nest is typically placed in a deep crevice (usually at least 1 m deep) in a vertical rock face."(ibid.), "rarely on building other site" (Fry et al. 2000, p. 593).

"The nest is a bulky, open-cupped bowl, its base made with coarse plant material (grass, twigs, roots, leaves, etc.); occasionally hum debris (rags, etc.) is used." (Tarboton, 2001).

"Our" bird had used for the basis of the nest the long, dry leaves of the quiver tree, the nest itself consists of grass, some few twigs, feathers from the Rüppel's Korhaan and some strings of our mop.

As "both sexes build or refurbish the nest, and it may be

successive broods and the site re-occupied in successive years"

(Tarboton 2001), we hope that the starlings have taken up the nest after we left and maybe we see them again in the next breeding season?
