In our recent paper, led by Madeleine Wheeler, we continue our examination of the effects of extreme heat on zebra finches. We have previously found that when young are raised in hot temperatures they end up being smaller as adults, and this could be explained either the direct effect of hot weather on their physiology, or perhaps on the ability of their parents to provision them with food during such hot conditions. Here we analysed nest visitation rates over a range of temperatures and demonstrated that, indeed, when temperatures became extremely hot, parents reduced the rate at which they visited nestlings. This result is consistent with our earlier findings that adults are unable to forage in such conditions (Funghi et al 2019) and that desert birds generally avoid breeding in the hottest times of the year (Englert Duursma et al 2017, 2019).
