Cuckoos, Cowbirds and Other Cheats
This book discusses the co-evolution of host defences and Common Cuckoo trickery, as well as one hundred species of brood parasitic birds and some puzzles.

AN EXPERIMENTAL STUDY OF CO-EVOLUTION BETWEEN THE CUCKOO, CUCULUS CANORUS, AND ITS HOSTS. II. HOST EGG MARKINGS, CHICK DISCRIMINATION AND GENERAL DISCUSSION
The variation in rejection of unlike eggs among different species of suitable cuckoo hosts is not related to the current costs or benefits of rejecting cuckoos, and it is suggested that the variation represents snap shots in evolutionary time of different stages of a species.
An introduction to behavioural ecology
This chapter discusses natural selection, Ecology and Behaviour Testing Hypotheses in Behavioural Ecology, and the design of Signals in Ecology and Evolution.
AN EXPERIMENTAL STUDY OF CO-EVOLUTION BETWEEN THE CUCKOO, CUCULUS CANORUS, AND ITS HOSTS. I. HOST EGG DISCRIMINATION
Three results suggest that the egg discrimination by suitable hosts has evolved in response to cuckoo parasitism, and Species unsuitable as hosts mainly showed little if any rejection of model eggs unlike their own.
Egg mimicry by cuckoos Cuculus canorus in relation to discrimination by hosts
It is shown by experiment that host discrimination against badly matching eggs is a selective force in gens maintenance and that cuckoos lay a better mimetic egg where the host species is apparently more discriminating.
Nestling cuckoos, Cuculus canorus, exploit hosts with begging calls that mimic a brood
It is suggested that the cuckoo needs vocal trickery to stimulate adequate care to compensate for the fact that it presents a visual stimulus of just one gape.
How selfish is a cuckoo chick?
Rapid calling reflects the way the cuckoo exploits the provisioning rules that hosts use to feed their own young, and whether cuckoos are likely to have gens-specific begging displays is discussed.
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 evolution of cuckoo parasitism: a comparative analysis
The results suggest that the evolution of cuckoo brood parasitism reflects selection from both ecological pressures and host defences, indicating that egg size is an adaptive trait in host–parasite coevolution.
