Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

Insect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Host Detection by Cuckoo Bumblebees: Choice Experiments Reveal Non‐Visual Cues Support Host Detection, but Accuracy Is Low

Entomologia Experimentalis et Applicata, EarlyView.
Female Bombus vestalis cuckoo bumblebees were introduced to a flight arena containing four identical opaque boxes, featuring slits to release volatiles from the bumblebees inside. When only one box contained a developing host colony, the cuckoos were able to locate their hosts among the four boxes with 66.2% accuracy.

Timing pattern of Common Cuckoo parasitism and its relation to host nest attendance

Ibis, EarlyView.
Classical works show the adaptive importance of precise timing of egg‐laying in brood parasitic Common Cuckoos Cuculus canorus to ensure sufficient incubation time and successful hatching. Laying in the late afternoon has been suggested to increase the chance of secretive parasitism and therefore escape the aggressive mobbing by hosts, yet this ...

Can nest design hinder brood parasitism success?

Journal of Avian Biology
Avian nest design varies depending on environmental factors but may also be influenced by between‐species interactions. In the brood parasitism context, hosts may evolve nest architectures that may limit parasite access to the nest cup, reduce parasite ...

The effect of Common Cuckoo parasitism on the annual productivity of a host population

Avian Research
Avian interspecific brood parasitism is an excellent system for studying coevolutionary processes in nature because brood parasites directly affect host reproductive success.

Great spotted cuckoo nestlings have no antipredatory effect on magpie or carrion crow host nests in southern Spain.

PLoS ONE, 2017
Host defences against cuckoo parasitism and cuckoo trickeries to overcome them are a classic example of antagonistic coevolution. Recently it has been reported that this relationship may turn to be mutualistic in the case of the carrion crow (Corvus ...

Continuous variation rather than specialization in the egg phenotypes of cuckoos (Cuculus canorus) parasitizing two sympatric reed warbler species. [PDF]

PLoS ONE, 2014
The evolution of brood parasitism has long attracted considerable attention among behavioural ecologists, especially in the common cuckoo system. Common cuckoos (Cuculus canorus) are obligatory brood parasites, laying eggs in nests of passerines and ...

Diversity of parasitic cuckoos and their hosts in China [PDF]

Chinese Birds, 2012
Abstract In this expose we provide the first review of host use by brood parasitic cuckoos in a multiple-cuckoo system in China, based on our own long-term field data and a compilation of observations obtained from the literature. In total, we found that 11 species of cuckoos utilized altogether 55 host species.

Wild Bee Conservation: Habitat Heterogeneity and Ecological Improvement in Agricultural Land With Open Grassland

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Here, we investigated the effects of different levels of habitat heterogeneity and of ecological improvement of habitat to increase foraging resources on wild bee communities in Austria and Luxembourg. We found that ecological improvement was important in Luxembourg for species richness and abundance but less so in Austria; here, habitat heterogeneity ...

Avian brood parasitism in Italy: another perspective

Avocetta, 2020
We present a quantitative analysis of the data reported in the only published review of parasitism frequency on hosts of Common Cuckoo Cuculus canorus in a Mediterranean area. We first eliminated a bias potentially introduced by the method by which data
