Many animals use vision to detect, discriminate, or recognize important objects such as prey,
predators, homes, or mates. These objects may differ in color and brightness—having …

The coevolutionary interactions between avian brood parasites and their hosts provide a
powerful system for investigating the diversity of animal coloration. Specifically, reciprocal …

The Southern Hemisphere differs from the Northern Hemisphere in many aspects. However,
most ecological and evolutionary research is conducted in the Northern Hemisphere and its …

Brood parasitic cuckoos lay their eggs in other birds' nests, whereafter the young cuckoo
hatches, ejects its nest-mates and monopolizes the care of the host parents. Theory predicts …

Despite a recent explosion of research on pattern recognition, in both neuroscience and
computer vision, we lack a basic understanding of how most animals perceive and respond …

Coevolution between interacting species is thought to increase biodiversity, but evidence
linking microevolutionary processes to macroevolutionary patterns is scarce. We leveraged …

Obligate avian brood parasites depend entirely on heterospecific hosts for rearing their
offspring. From hatching until independence, the young parasites must deal with the …

In contrast to the thoroughly studied incubation and nestling periods, the postfledging period
of the Common Cuckoo (Cuculus canorus) remains virtually unknown. Here, we report …

Decades of research have shown that the coevolutionary arms race between avian brood
parasites and their hosts can promote phenotypic diversification in hosts and brood …

Obligate brood parasites lay their eggs in nests of other species, with host parents bearing
the cost of raising their offspring. These costs imposed on hosts select for the evolution of …
