大卫·莱克 (David Lack) 对鸟类繁殖生物学研究的两个最具原创性和最重要的贡献是他对求偶进食重要性的讨论 (Lack, 1940) 和确定窝数 (Lack, 1947)。他最初笼统地认为，通过自然选择的作用，可以调整窝产数，以适应父母可以成功抚养的最大幼崽数量（Lack，1954）。然而，他在后来的著作中同意，在某些物种中，由于雌性在产蛋时可获得的营养储备，每窝产蛋量可能会被限制在这个最佳数量以下（Lack，1963；1966；1968）。如果雌性的营养状况确实受到这种限制，那么求偶进食现象就具有特殊的意义，因为雄性提供的食物可能直接有助于产卵所需的储备（Lack，1966年第23页；1968年第287页）。现在有证据表明，几个物种的求偶进食对产蛋雌性的营养摄入有显着贡献（Royama，1966；Brown，1967；Krebs，1970；Nisbet，1973）。本文报告了对普通燕鸥的求偶进食、产卵数量、蛋大小和产蛋雌性体重之间关系的最新观察。
Two of David Lack’s most original and important contributions to the study of breeding biology in birds were his discussions of the significance of courtship-feeding (Lack, 1940) and the determination of clutch size (Lack, 1947). He originally argued in general terms that clutch size is adjusted, through the action of natural selection, to correspond to the maximum number of young that the parents can raise successfully (Lack, 1954). However, he agreed in his later writings that in some species clutch size may be limited below this optimum number by the nutritional reserves available to the female at the time of laying (Lack, 1963; 1966; 1968). If the nutritional state of the female is indeed limiting in this way, the phenomenon of courtship-feeding takes on special significance, because the food provided by the male may contribute directly to the reserves required for egg laying (Lack, 1966 p. 23; 1968 p. 287). There is now evidence in several species that courtship-feeding contributes significantly to the nutritional intake of the laying female (Royama, 1966; Brown, 1967; Krebs, 1970; Nisbet, 1973). This paper reports recent observations of the relationships between courtship-feeding, clutch size, egg size, and the weight of laying females in Common terns Sterna hirundo.
