鸟类家族之间的卵形有显著的差异，这种差异可能反映了对不同选择压力的适应。在Guillemot Uria aalge的经典案例中，TsCHANTz et al .（1969）已经表明，有标记的梨形减少了鸡蛋从用于繁殖的悬崖上掉下来的风险。在大多数其他情况下，蛋的形状仍然无法解释，LACK（1968）指出，“几乎没有研究已经进行了他们的意义”。最近的一个例外是VON HAARTMAN（1971）对长/宽比随蛋大小增加的趋势的研究。涉禽类（主要是斑科和鹬科）的卵明显偏离球形，至少在ANDERSSON，M。1978年：最佳蛋形的涉禽。Ornis Fennica 55：105-109 .
There is a remarkable variation in egg shape among bird families, a variation which probably reflects adaptations to different selective pressures. In the classical case of the Guillemot Uria aalge, TsCHANTz et al . (1969) have shown that the marked pear-shape reduces the risk that the egg will fall off the cliff-ledge used for breeding . In most other cases the egg shapes have remained unexplained, and LACK (1968) noted that "virtually no research has been carried out on their significance". A recent exception is VON HAARTMAN'S (1971) study of the trend in the length/width ratio with increasing egg size . The eggs of waders (mainly Charadriidae and Scolopacidae) deviate markedly from the spherical form, which should be optimal in at least ANDERSSON, M. 1978 : Optimal egg shape in waders .
