Describing the range of avian egg shapes quantitatively has long been recognized as
difficult. A variety of approaches has been adopted, some of which aim to capture the shape …

Why are avian eggs ovoid, while the eggs of most other vertebrates are symmetrical? The
interaction between an egg and its environment likely drives selection that will shape eggs …

Often considered a textbook example of coevolution, common cuckoo (Cuculus canorus)
eggs are among the best-studied eggs in the world. Female cuckoos belong to genetically …

The existence of substantial variation in the accuracy of resemblance of mimics to their
models remains a fundamental evolutionary question, and the ability to quantify mimetic …

A fundamental question in biology is how diversity evolves and why some clades are more
diverse than others. Phenotypic diversity has often been shown to result from morphological …

Many hosts of obligate brood‐parasitic birds use variation in the coloration and pattern of
eggshells to identify and reject foreign eggs from their nests. However, egg‐rejection …

The mutually antagonistic processes producing adaptations and counter-adaptations in
avian brood parasites and their hosts provide a model system for the study of coevolution; …

Simple Summary Most birds build nests for laying eggs and rearing their offspring. They
frequently clean their nests by removing foreign objects, such as leaves, small branches …

This paper proposes a new methodology to quantify patterns of egg shape variation using
geometric morphometrics of three-dimensional landmarks captured on digitally …

Hosts may evolve more than one egg type within a population (egg polymorphism) to make
mimicry of any one individual more difficult. This process of co-evolution between cuckoos …
