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 corone) and its brood parasite, the great spotted cuckoo (Clamator glandarius), given that experimentally and naturally parasitized nests were depredated at a lower rate than non-parasitized nests. This result was interpreted as a consequence of the…

Brood Parasites as Predators: Farming and Mafia Strategies
TLDR
It is suggested that costs of retaliatory behaviours together with phenotypic plasticity of magpie and great spotted cuckoo’s defences and counter-defences are the crucial points explaining these differences in parasitism rates.
Does nest sanitation elicit egg rejection in an open-cup nesting cuckoo host rejecter?
TLDR
This study indicated that nest sanitation behavior of Brown-breasted Bulbuls did not influence their egg recognition and that egg discrimination ability of Brown the Bulbul was not directly related to nest sanitationbehavior.
Predation risk affects egg-ejection but not recognition in blackbirds
TLDR
It is shown that predation risk seems to modulate host defenses against brood parasites in common blackbirds, but depending on the threat posed by predators, external stimuli to brood parasite-host systems can influence egg-rejection decisions.
Evolution of Avian Brood Parasitism and Phylogenetic History of Brood Parasites
TLDR
The study of the evolution of brood parasitism and its phylogenetic history is likely to further advance rapidly in the near future as genomic approaches become feasible in non-model species and phylogenetic analyses techniques are developed at an equally breath-taking rate.
Formal comment to Soler et al.: Great spotted cuckoo nestlings have no antipredatory effect on magpie or carrion crow host nests in southern Spain
TLDR
This paper aims to demonstrate the efforts towards in-situ applicability of ULTIMATE EMMARM, which aims to provide real-time information about the phytochemical properties of woodpecker decline and its consequences.
Defences against brood parasites from a social immunity perspective
TLDR
Here, defences against brood parasitism are considered in the light of social immunity, at different stages of parasite encounter, addressing where conflicts occur and how they might be resolved.

Nest defence by Magpies(Pica pica) and the brood parasitic Great Spotted Cuckoos(Clamator glandarius) in parasitized and unparasitized nests
TLDR
It is found that in a Spanish Magpie population which is heavily parasitized by the brood parasitic Great Spotted Cuckoo, Magpies defend unparasitized more frequently than parasitized nests, and at the end of the nestling period morerequently than in other stages of the breeding cycle.
From Parasitism to Mutualism: Unexpected Interactions Between a Cuckoo and Its Host
TLDR
Overall, in years of high predation pressure, the presence of cuckoos improves the crow's breeding success, but when there are fewer predators around, parasitism reduces crow fitness, and the outcome of these counterbalancing effects fluctuates between parasitism and mutualism each season.
Great Spotted Cuckoo Nestlings but not Magpie Nestlings Starve in Experimental Age‐Matched Broods
TLDR
It is shown that great spotted cuckoo chicks starved in 20.2 per cent of the parasitized magpie nests even in absence of size asymmetries, which is the first record of non-evictor brood parasitic nestlings starving without being smaller than their host nestmates in a frequently used host species.
Eavesdropping cuckoos: further insights on great spotted cuckoo preference by magpie nests and egg colour
TLDR
Results from these two experiments suggest that great spotted cuckoos cue on magpie nest characteristics and the appearance of eggs to decide parasitism, and confirm, for the first time, the ability of cuckoo to distinguish between eggs of different colours within the nest of their hosts.
MAGPIE HOST MANIPULATION BY GREAT SPOTTED CUCKOOS: EVIDENCE FOR AN AVIAN MAFIA?
TLDR
If the egg of the parasitic great spotted cuckoo Clamator glandarius is removed from nests of its magpie Pica pica host, nests suffer significantly higher predation rates than control nests in which parasite eggs have not been removed.
Great spotted cuckoo fledglings are disadvantaged by magpie host parents when reared together with magpie nestlings
TLDR
The results indicate that great spotted cuckoo fledglings reared in mixed broods together with magpie nestlings were disadvantaged by magpie adults with respect to feeding patterns, and imply that the presence of host's own nestlings for comparison may be a crucial clue favouring the evolution of fledgling discrimination.
Change in host rejection behavior mediated by the predatory behavior of its brood parasite
TLDR
In study plots with a high density of cuckoos, the probability for a rejecter magpie nest of being revisited and depredated by a cuckoo is high, particularly for replacement clutches, and, therefore, the cost for magpies of rejecting a cuckedoo egg in a replacement clutch is increased.
Spatiotemporal variation of host use in a brood parasite: the role of the environment
TLDR
It is suggested that the habitat constraints parasitism on magpies in the north, driving cuckoo host choice toward the crows, contributes to the coevolutionary scenario where the pressure that the parasite puts on a host species in a given place critically depends on the environmentally mediated interaction between the same parasite and a different host.
Brood mate eviction or brood mate acceptance by brood parasitic nestlings? An experimental study with the non-evictor great spotted cuckoo and its magpie host
TLDR
It is suggested that chick killing in great spotted cuckoos may not be adaptive mainly because another, less costly strategy, outcompeting host nestmates for food, is efficient for successful parasitism of magpie hosts.
