“…The Moustached Warbler seems to prefer extensive wetlands, but reed stand edges (Cramp 1998). The Great Reed Warbler nests in pure reed stand edges, even along channels (Cramp 1998, Moskát & Honza 2000, Batáry & Báldi 2005), but often forages in habitats other than reed, which can be even several hundreds meter apart from the nest (Csörgő 1995, Cramp 1998. This may explain its preference for the nonwetland landscape.…”

“…In other words, parasitism is non-random. Such non-randomness has been documented for nest sites of hosts: Alvarez (1993), Øien et al (1996), Clotfelter (1998) and Moskat & Honza (2000) found that host nests closer to potential perches such as trees and those more obvious to a human observer were more likely to be parasitized, and Hauber (2001) showed that Phoebe Sayornis phoebe nests were more likely to be parasitized if located under eaves than under bridges. Hauber et al (2004) showed that this nonrandomness in parasitism can constrain the evolution of host defences because of the heterogeneities in costs associated with brood parasitism.…”

The interactions between brood parasitic birds and their host species provide one of the best model systems for coevolution. Despite being intensively studied, the parasite-host system provides ample opportunities to test new predictions from both coevolutionary theory as well as life-history theory in general. I identify four main areas that might be especially fruitful: cuckoo female gentes as alternative reproductive strategies, non-random and nonlinear risks of brood parasitism for host individuals, host parental quality and targeted brood parasitism, and differences and similarities between predation risk and parasitism risk. Rather than being a rare and intriguing system to study coevolutionary processes, I believe that avian brood parasites and their hosts are much more important as extreme cases in the evolution of life-history strategies. They provide unique examples of trade-offs and situations where constraints are either completely removed or particularly severe.

“…The great reed warbler is a commonly parasitized cuckoo host in Hungary (41-68% parasitism rate) (Moskát et al, 2008b), with parasitism rate mainly dependent on the availability of trees in the close vicinity of the nests, serving as vantage points for the cuckoo (Moskát and Honza, 2000). This host rejects ca.…”

SUMMARYMany avian hosts have evolved antiparasite defence mechanisms, including egg rejection, to reduce the costs of brood parasitism. The two main alternative cognitive mechanisms of egg discrimination are thought to be based on the perceived discordancy of eggs in a clutch or the use of recognition templates by hosts. Our experiments reveal that the great reed warbler (Acrocephalus arundinaceus), a host of the common cuckoo (Cuculus canorus), relies on both mechanisms. In support of the discordancy mechanism, hosts rejected their own eggs (13%) and manipulated ('parasitic') eggs (27%) above control levels in experiments when manipulated eggs were in the majority but when clutches also included a minority of own eggs. Hosts that had the chance to observe the manipulated eggs daily just after laying did not show stronger rejection of manipulated eggs than when the eggs were manipulated at clutch completion. When clutches contained only manipulated eggs, in 33% of the nests hosts showed rejection, also supporting a mechanism of template-based egg discrimination. Rejection using a recognition template might be more advantageous because discordancy-based egg discrimination is increasingly error prone with higher rates of multiple parasitism.
