摘要在绝大多数动物类群中，雄性不参与父母照顾，但大量的父亲照顾是常见的鸟类物种。我们研究了男性和女性的孵化贡献家雀（Passer arteriticus），量化的孵化行为的自由生活，个别色带的父母在47个筑巢周期。我们还测量了男性和女性孵化表面的相对温暖。雌性花更多的时间孵化比他们的男性合作伙伴，和女性的孵化时间担任孵化成功的最佳单一预测。单独考虑，男性孵化时间与孵化成功率呈负相关，但这种影响是无效的女性孵化时，考虑到。女性比男性有更温暖的卵囊，这种差异可能反映了更大的发展育雏补丁和孵化的有效性，在该性别。在这里，男性徽章的大小是没有明显相关的男性或女性孵化模式或孵化成功。劳动部门：通过家庭旅客的产前护理进行孵化和引导
Abstract In the great majority of animal taxa, males do not participate in parental care, but substantial paternal care is common across avian species. We examined male and female incubation contributions in House Sparrows (Passer domesticus), quantifying the incubation behavior of free-living, individually color-banded parents during 47 nesting cycles. We also measured the relative warmth of male and female incubation surfaces. Females spent more time incubating than their male partners, and female time incubating served as the best single predictor for hatching success. Considered alone, male time incubating correlated negatively with hatching success, but that effect was nullified when female incubation was taken into account. Females had warmer abdomens than males, a difference that may reflect greater development of brood patch and effectiveness of incubation in that sex. Here, male badge size was not demonstrably associated with either male or female incubation patterns or hatching success.
