- ... Avian hosts of brood parasites can evolve anti‐parasitic defenses to recognize and reject foreign eggs from their nests. Theory predicts that higher inter‐clutch and lower intra‐clutch variation in egg appearance facilitates hosts to detect parasitic eggs as egg‐rejection mainly depends on the appearance of the egg. Therefore, we predict that egg patterns and rejection rates will differ when hosts ...

- ... Parasites may, in multi-parasite systems, block the defenses of their hosts and thus thwart host recognition of parasites by frequency-dependent selection. Nest defenses as frontline may block or promote the subsequent stage of defenses such as egg recognition. We conducted comparative studies of the defensive strategies of a host of the Oriental cuckoo Cuculus optatus, the yellow-bellied prinia P ...

- ... Different populations of a host species subject to variable patterns of selection due to cuckoo parasitism provide an optimal situation for studying natural selection and coevolution in action. We compared egg appearance and egg-rejection behavior of 2 common cuckoo ( Cuculus canorus ) hosts, the ashy-throated parrotbill ( Paradoxornis alphonsianus ) and the vinous-throated parrotbill ( Paradoxorn ...
