Great spotted cuckoos show dynamic patterns of host selection during the breeding season. The importance of laying stage and parasitism status of magpie nests
It is detected that cuckoos preferred to parasitize magpie nests at the laying stage but, mainly, those that already harbored one or two cuckoo eggs, which may seem counterintuitive, implies that brood parasite–host interaction is dynamic depending on phenology.
Socially Acquired Host-Specific Mimicry and the Evolution of Host Races in Horsfield'S Bronze-Cuckoo Chalcites Basalis
It is suggested that plasticity in the development of host-specific traits after parasitism is likely to reduce selection for host race formation.
Factors influencing host nest use by the brood parasitic Asian Koel (Eudynamys scolopacea)
Investigation of patterns of nest use among three commonly used host species of the Asian Koel in Bangladesh indicates that brood parasites in general use many similar cues when selecting host nests, and indicate that brood parasite–host systems correspond well with findings from other brood parasite-host systems.
"Jack-of-all-trades" egg mimicry in the brood parasitic Horsfield’s bronze-cuckoo?
The analyses support the idea that the Horsfield’s bronze-cuckoo egg is a jack-of-all-trades mimic, lying in an intermediate position in avian visual space between the eggs of its various hosts, suggesting that jack- of- all-trading mimicry may be favored among brood parasites that parasitize hosts with a narrow range of egg phenotypes and where individual female brood parasites exploit multiple host species.
Differential reproductive success favours strong host preference in a highly specialized brood parasite
The results indicate that screaming cowbirds have the potential to colonize novel hosts, but higher reproductive success in the current host may favour host fidelity, and coevolutionary theory predicts increasing host specificity the longer the parasite interacts with a particular avian community.
Do cuckoos imprint on hosts, micro-habitats, or nest sites? Parasitism preferences in the common cuckoo (Cuculus canorus)
Diverse nest-building behaviors used for constructing delicate and diverse kinds of nests constitute one of the most impressive and typical traits for birds. However, some bird species do not possess


Brood parasitism by Horsfield's Bronze-Cuckoo in a fragmented agricultural landscape in Western Australia
Parasitism by Horsfield's Bronze-Cuckoos did not appear to have a negative effect on the persistence of their major host, the Blue-breasted Fairy-wren, Malurus pulcherrimus, in this area.
Cuckoo females preferentially use specific habitats when searching for host nests
Results indicate that cuckoo females show habitat preference when searching for suitable host nests, but owing to the habitat specificity of hosts the data cannot disprove a potential role of host specificity in cuckoos females.
Does the great spotted cuckoo choose magpie hosts according to their parenting ability?
The probability of survival of the parasite chicks increased if cuckoo eggs were laid in the nests of high-quality hosts originally chosen by the parasite.
How do cuckoos find their hosts? The role of habitat imprinting
This work proposes 'habitat imprinting' as an alternative mechanism for host selection and provides evidence that cuckoos are able to remember acquired information about a familiar habitat and proposes that host specificity would be strengthened if cuckoo use a sequence of several mechanisms, rather than just one, to find their hosts.
Parentage and host preference in the common cuckoo Cuculus canorus
The maternal relationships were used to record each cuckoo female's host choice and the results supported the Host Preference Hypothesis since no female was recorded to have parasitised more than one of four congeneric host species breeding in the area.
Acceptance by the splendid fairy-wren of parasitism by Horsfield's bronze-cuckoo: further evidence for evolutionary equilibrium in brood parasitism
It is suggested that a long coevolutionary history of brood parasitism and nest predation has favored adjustment to the host's life-history pattern, to the point where total acceptance of the cuckoo egg is now an evolutionarily stable strategy.
The evolution of egg rejection by cuckoo hosts in Australia and Europe
It is suggested that parasitism is always sufficiently costly to select for host defenses and that the evolution of defenses may be limited by proximate constraints such as visibility within the nest.
The comparative breeding behaviour of two sympatric cuckoos, Horsfield's Bronze-Cuckoo Chrysococcyx basalts and the Shining Bronze-Cuckoo C. lucidus, in Western Australia: a new model for the evolution of egg morphology and host specificity in avian brood
Field observations and experiments with egg models indicated that neither of the major hosts, nor the secondary host in common, discriminate against foreign eggs, and the adaptive significance of competition between cuckoos as a selective agent for cuckoo egg morphology and host specificity is discussed.
Host species affects the growth rate of cuckoo (Cuculus canorus) chicks
It is found that cuckoo nestlings raised by the larger host species, the great reed warbler, grew significantly faster and became statistically significantly larger at fledging than nestlingsraised by the smaller host, the reing warbler.
