Coevolution between antagonistic species has produced instances of exquisite mimicry.
Among brood-parasitic cuckoos, host defences have driven the evolution of mimetic eggs …

The analysis of colour pattern geometry is not as well advanced as the analysis of colour,
although this reflects a lack of an analytical framework. The present study proposes an …

Animal camouflage is a longstanding example of adaptation. Much research has tested how
camouflage prevents detection and recognition, largely focusing on changes to an animal's …

Coevolutionary arms races are a powerful force driving evolution, adaptation, and
diversification. They can generate phenotypic polymorphisms that render it harder for a …

Arms races between avian brood parasites and their hosts often result in parasitic mimicry of
host eggs, to evade rejection. Once egg mimicry has evolved, host defences could escalate …

The geometrical properties of eggs–such as volume and surface area–have uses ranging
from ecological, physiological and morphological studies in birds, to predictions of chick …

Camouflage is a widespread phenomenon throughout nature and an important antipredator
tactic in natural selection. Many visual predators have keen color perception, and thus …

Accurate recognition of salient cues is critical for adaptive responses, but the underlying
sensory and cognitive processes are often poorly understood. For example, hosts of avian …

Improved camouflage through ontogenetic colour change confers reduced detection risk in

We reviewed information on nest sanitation (nest cleaning) by passerine birds because the
act of cleaning nests is thought to be associated with egg rejection by hosts of brood …
