    Heat tolerance of Southern Pied Babblers in the Kalahari Desert : how will they respond to climate change?
    (2011) Du Plessis, Katherine; Hockey, Phil A R; Ridley, Amanda; Martin, Rowan; Cunningham, Susan
    An increasing incidence of mass mortalities of birds in hot deserts suggests that birds may be appropriate candidates for assessing how natural selection, under the influence of climate change, drives adaptation. ... The effects of ambient temperature on daily weight gain, foraging effort and efficiency and the presence of heat-dissipation behaviours were assessed to determine the mechanisms by which increased temperature affect babbler body condition.
