Common cuckoo eggs are more resistant to puncture by the host. [PDF]

Int J Parasitol Parasites Wildl
The puncture resistance hypothesis suggests that thick-shelled eggs of parasitic birds can resist puncture-ejection by the host. However, few experiments have yet been conducted to test this hypothesis in terms of natural host behavior (e.g., pecking at foreign eggs). To explore whether the eggshells of common cuckoos (Cuculus canorus) are resistant to

Population decline is linked to migration route in the Common Cuckoo. [PDF]

Nat Commun, 2016
Migratory species are in rapid decline globally. Although most mortality in long-distance migrant birds is thought to occur during migration, evidence of conditions on migration affecting breeding population sizes has been completely lacking. We addressed this by tracking 42 male Common Cuckoos from the rapidly declining UK population during 56 autumn ...

Egg eviction imposes a recoverable cost of virulence in chicks of a brood parasite. [PDF]

PLoS ONE, 2009
BackgroundChicks of virulent brood parasitic birds eliminate their nestmates and avoid costly competition for foster parental care. Yet, efforts to evict nest contents by the blind and naked common cuckoo Cuculus canorus hatchling are counterintuitive as

Previously unknown behavior in parasitic cuckoo females: male-like vocalization during migratory activity

Avian Research, 2021
Background In the last decade, enigmatic male-like cuckoo calls have been reported several times in East Asia. These calls exhibited a combination of vocal traits of both Oriental Cuckoo (Cuculus optatus) and Common Cuckoo (Cuculus canorus) advertising ...

Importance of cooperation: How host nest defenses effectively prevent brood parasitism from the cuckoos

iScience, 2023
Summary: As the frontline defense against avian brood parasitism, nest defense is important in reducing nest parasitism and increasing host fitness.

Common Hawk-Cuckoo (Hierococcyx varius)

Zoos' Print Journal, 2020
The Indian Hawk-Cuckoo (Hierococcyx varius Vahl.) was found to be a brood parasite on Pale-capped Babbler, Turdoides affinis (Jerdon) in Kerala Agricultural University (KAU) Campus, Thrissur. The chances of babbler nests parasitised by cuckoos is maximum when they build nests on open-crowned and exposed trees at heights more than 5m.

Why should Common Cuckoos Cuculus canorus lay their eggs in host nests? [PDF]

, 2016
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.

Coevolutionary Interactions Between Common Cuckoos and Corn Buntings [PDF]

The Condor, 2006
AbstractAlthough Old World buntings (Emberizinae) may be considered suitable Common Cuckoo (Cuculus canorus) hosts, there is at present no evidence that any of the European species are regularly parasitized. Most historical parasitism records refer to the Yellowhammer (Emberiza citrinella) and Reed Bunting (E. schoeniclus). Both of these species reject

Variation in plasma oxidative status and testosterone level in relation to egg-eviction effort and age of brood-parasitic common cuckoo nestlings [PDF]

, 2012
To avoid competition for parental care, brood-parasitic Common Cuckoo (Cuculus canorus) nestlings evict all of the host's eggs and nestlings within a few days after hatching.
