Visual camouflage evolution in animals depends on both light’s interaction with its surroundings and the limits of what the natural observers of the camouflage can see. Changes in lighting – such as t...

Abstract. Recognizing one’s own eggs is crucial for birds, especially for hosts of brood parasites that must identify and reject different-looking parasiti

Hybrid photoreceptors in larval deep-sea fish reveal evolution of an alternative developmental trajectory for vertebrate vision.

The nest parasites get a bad rap for making other birds raise their young, but study by study, Mark Hauber and his “Cowbird Lab” have revealed a species worthy of respect.

The exquisite eggshell mimicry found in many cuckoo-host systems has been the textbook example of a coevolutionary arms race [1]. In this system, cuckoos lay their eggs in their hosts' nests leaving t...

Often, as the magnitude of a stimulus increases, it becomes harder to detect small changes in this stimulus (termed the magnitude effect). We investigated
