- Most bird chicks need parental care to survive. In biparental species the chicks have greater chances of success if both parents participate in this task, especially under hostile situations. An international team of scientists has revealed that when temperatures rise, males and females in pairs of plovers shift incubation more frequently….The paper…analysed the behaviour of 36 populations of 12 plover species. Its results reveal that male plovers assist the females during daytime incubation. “Males’ participation in daytime incubation increases both with ambient temperature and with as the variability of maximum temperatures during the incubation period,” the expert stresses. The research demonstrates that a rise in temperature changes these bird pairs’ behaviour and their daily routine in terms of nest attendance….The conclusion of this new paper is that climate variations strongly influence parental cooperation.
