oa Madoqua - Seasonal effects on nutrition, reproduction and aspects of thermoregulation in the Namaqua sandgrouse (Pterocles namaqua)



On the basis of both field observations of nestine birds and detailed chemical and morphological studies on 10 birds (5 male and 5 female) per month, it would appear as if P. namaqua favours the cooler winter months for breeding in the Namib Desert Park. In view of the simple nature of the nest scrape and studies on the thermoregulatory behaviour of this species, we have concluded that soil-surface temperatures play a critical role in determining the success of breeding.
