Are both notes of the common cuckoo’s call necessary for familiarity recognition?

Behavioural Processes, 2018
Common cuckoos (Cuculus canorus) are best known for their simple two-note calls ("cu-coo"), which are uttered only by males during the breeding season. A previous playback study revealed that territorial males were more tolerant toward playbacks of the calls of familiar, neighbouring individuals than toward unfamiliar, stranger simulated intruders ...

Genetic evidence for female host-specific races of the common cuckoo

Nature, 2000
The common cuckoo Cuculus canorus is divided into host-specific races (gentes). Females of each race lay a distinctive egg type that tends to match the host's eggs, for instance, brown and spotted for meadow pipit hosts or plain blue for redstart hosts. The puzzle is how these gentes remain distinct.

Adaptations of bramblings and chaffinches towards parasitism by the common cuckoo

Animal Behaviour, 1992
Abstract A coevolutionary arms-race between the common cuckoo, Cuculus canorus, and its hosts includes adaptations such as mimetic cuckoo eggs and counter-adaptations such as rejection of the parasitic eggs and aggression towards the parasite by the host.

Signals of need in parent–offspring communication and their exploitation by the common cuckoo

Nature, 1999
Nestling birds present vivid gapes and produce loud calls as they solicit food, but the complexity of the display is poorly understood. Here we explain the function of reed warbler begging signals and show how they are exploited by the common cuckoo, Cuculus canorus, a brood parasite.

Common cuckoo female host selection is not determined by host quality but can affect cuckoo nestling growth when parasitising Common redstarts

ABSTRACT Common cuckoo ( Cuculus canorus ) females lay their eggs in the nests of other avian hosts, relying on parental care provided by parasitised hosts. Therefore, it would benefit cuckoo females to target high-quality individual hosts, able to provide optimal parental care ...

Egg colour influences egg removal by common cuckoos (Cuculus canorus)

Behavioural Processes
Brood parasitic cuckoos usually remove one host egg before laying their own. The purpose of this behaviour is still not fully understood. Recent studies that investigated cognitive mechanisms underlying egg removal found that cuckoos preferentially remove brighter eggs because darker eggs may be more cryptic. However, the role of chromatic differences (
