Swainson's Spurfowl trekking south

The first year of SABAP2 is nearly finished and I have observed the following range expansion of the Swainson's Spurfowl (Pternistis swainsonii) in my surveys. After Deon du Plessis commented (see post of 25.05.2008) on his observations of this species through the 1990's, I started to look out particulartly for them. On 16.06.2008 I observed 5 birds in a small family covey along the Melkspruit at S30.76249 E26.65912 (in pentad 3045_2635 and QDGC 3026DC). The birds were foraging near the edge of a fallow land – nearer to the taller growth where there were enough protection should the need to hide arise.

This is the most southerly of my own observations thus far – 16,5km more southwest than the spots Deon had mentioned in his comment. It corresponds with Deon's suggestion that the birds expand their range along the rivers and streams – especially with the abundance of food in cultivated lands and where other agricultural activity suiting them occur. Interestingly enough my observations of these birds here on the southwestern border of their range were always in the vicinity of generous water supply – larger farm dams that would have water through the dry season and perennial streams. According to the literature, they normally drink very regularly - in the morning and evening.
