- 摘要：
- e typically limited, clutch size and egg mass are expected to be constrained, and this putative trade-off between offspring number and size is at the core

- 摘要：
- The mass of a bird’s egg is a critical attribute of the species’ life history and represents a fundamental component of reproductive effort

- 摘要：
- for seabirds. Food availability is a known driver of body mass and reproductive investment in birds, but these traits may also depend on individual effects
Data from: Two eggs, two different constraints: a potential explanation for the puzzling intra-clutch egg size dimorphism in Eudyptes penguins

- 摘要：
- two-egg clutch size of Eudyptes penguins has recently been proposed to be a unique example of a maladaptive phenotypic stability, while their egg mass

- 摘要：
- Background: Oviparous females have three main options to increase their reproductive success: investing into egg number, egg mass and/or egg care
Data from: Pelvis morphology suggests that early Mesozoic birds were too heavy to contact incubate their eggs
