Laying Plasticity in an Avian Brood Parasite [PDF]

The Auk, 2005
Abstract Females of some bird species “steal“ the parental care of other breeding individuals by laying eggs parasitically in their nests. In most populations, conspecific brood parasites lay parasitically before laying in their own nests. By contrast, in a young and expanding Common Moorhen (Gallinula chloropus) population, 17.4% (n =

Dataset from Host density predicts the probability of parasitism by avian brood parasites

, 2019
The spatial distribution of hosts can be a determining factor in the reproductive success of parasites. Highly aggregated hosts may offer more opportunities for reproduction but can have better defences than isolated hosts.

Loss of graded enemy recognition in a Whitehead population allopatric with brood-parasitic Long-tailed Cuckoos

Avocetta, 2020
Many avian hosts of brood parasitic birds discriminate between various types of threats at the nest and may respond with categorically different, specifically anti-predatory or anti-parasitic behaviors. Alternatively, hosts may adjust their responses to

The frontline of avian brood parasite–host coevolution

Animal Behaviour, 2012
The interactions between avian interspecific brood parasites and their hosts provide tractable and informative systems for investigating coevolution. Generally, these investigations have emphasized the egg and chick stages of the coevolutionary arms race; however, recent studies demonstrate that coevolution operates at all stages of the host nesting ...

Did extreme nest predation favor the evolution of obligate brood parasitism in a duck? [PDF]

, 2022
Obligate brood parasites depend entirely on other species to raise their offspring. Most avian obligate brood parasites have altricial offspring that require enormous amounts of posthatching parental care, and the large fecundity boost that comes with ...

Experimental shifts in intraclutch egg color variation do not affect egg rejection in a host of a non-egg-mimetic avian brood parasite.

PLoS ONE, 2015
Avian brood parasites lay their eggs in the nests of other birds, and impose the costs associated with rearing parasitic young onto these hosts. Many hosts of brood parasites defend against parasitism by removing foreign eggs from the nest.

Model eggs fail to detect egg recognition in host populations after brood parasitism is relaxed

Frontiers in Zoology, 2020
Background Obligate brood parasites exert strong selective pressure on target hosts. In response, hosts typically evolve anti-parasitism strategies, of which egg recognition is one of the most efficient.

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.
