在巢箱中繁殖的二次腔巢鸟进行了一些关于配偶选择、繁殖性能和生活史策略的研究。虽然已经认识到需要进行比较研究，但在巢箱中繁殖的种群往往没有与在自然腔中繁殖的种群进行比较。我们比较了在巢箱和自然腔中繁殖的树燕的生态学，以确定树燕的巢箱种群是否是自然种群的准确模型。两种筑巢环境的巢址特征——巢址分布和巢腔高度相似。自然洞穴入口面积的增大导致自然种群种间竞争加剧，竞争对手更大，物种更多，每种物种的丰度更高。与巢箱相比，自然腔中的卵蛋数量更小，可能是因为自然腔中的地板面积更小。初出茅庐的成功没有什么不同……
Several studies concerned with mate choice, reproductive performance, and life history strategies have been conducted with secondary cavity nesting birds breeding in nest boxes. Although the need for comparative studies has been recognized, populations breeding in nest boxes often have not been compared with those breeding in natural cavities. We compared the ecology of Tree Swallows breeding in nest boxes and natural cavities to determine if nest box populations of Tree Swallows are accurate models of natural populations. Two nest site characteristics, nest site dispersion and cavity height, were similar for birds in both nesting environments. Greater cavity entrance area at natural cavities resulted in increased interspecific competition in natural populations, involving larger competitors, more species, and a greater abundance of each species. Clutch size was smaller in natural cavities compared with nest boxes, likely because floor area was smaller in natural cavities. Fledging success did not differ ...
