Research suggests that high temperatures over a few days or weeks can have negative effects on foraging and body mass. In the Kalahari, air temperatures have already risen more than 2°C in a few decades. Desert temperatures and breeding birdsFirst we examined air temperature and rainfall data from the South African Weather Service for the Kalahari region between 1960 and 2020. The frequency and severity of drought have not changed but spring and summer average daily maximum air temperatures have been increasing. We found that breeding output was negatively correlated with increasing air temperatures and the occurrence of drought within the breeding season.
