The effect of Common Cuckoo parasitism on the annual productivity of a host population
Avian interspecific brood parasitism is an excellent system for studying coevolutionary processes in nature because brood parasites directly affect host reproductive success.

Threats to Nature's Contributions to People Provided by Terrestrial Vertebrates Across Europe
ABSTRACT Aim Species and ecosystem processes provide essential benefits to people, known as Nature's Contributions to People (NCP). However, we still lack a comprehensive understanding of NCP provided by terrestrial vertebrates on a macroecological scale, and of the threats they face. To address this, we built a comprehensive dataset that documents the

XI.—Some Reflections on the Breeding‐habits of the Cuckoo (Cuculus canorus) [PDF]
Summary.Having, then, dealt with the main theories and conclusions concerning the breeding‐habits of the Cuckoo, the results I arrive at are as follows, those based on theory being marked with an asterisk:— *The Cuckoo is probably polygamous. The eggs vary more in colour and markings than those of any known species. Their main distinctive features are

Video evidence that cuckoos farm their hosts by ejecting nestlings
When host nests are scarce, avian brood parasites would benefit from behaviours that increase the availability of suitable nests. Several studies reported ejection of host nestlings from nests by brood parasites; however, whether brood parasites do so to

Why should Common Cuckoos Cuculus canorus lay their eggs in host nests? [PDF]
Capsule Brood parasitic Common Cuckoo Cuculus canorus chicks hatch earlier than the nestlings of their Great Reed Warbler Acrocephalus arundinaceus hosts, but hatching priority is less certain when cuckoo eggs are laid after the onset of host incubation.

Because of its parasitic habits, reproduction costs of the common cuckoo (Cuculus canorus) are mostly spent in pre-laying activities. Female costs are limited to searching host nests and laying eggs, whereas, males spend time in performing intense vocal ...

Retention of the Full Visual Opsin Repertoire in Some Australian Cryptozoic Lizards
This study investigates the link between visual evolution and fossorial habits in the endemic Australian skink genus Lerista. We provide evidence for positive site‐specific selection in all 4 cone opsins, as well as relaxed selection specific to LWS. We also provide evidence of selection linked to limb reduction, an indicator of fossorial adaptation ...

First-Time Migration in Juvenile Common Cuckoos Documented by Satellite Tracking.
Being an obligate parasite, juvenile common cuckoos Cuculus canorus are thought to reach their African wintering grounds from Palearctic breeding grounds without guidance from experienced conspecifics but this has not been documented.
