“…In our study, the first individuals were observed on 1 May and the first egg was recorded on 3 May. On the other hand, the first individuals in Japan were observed on 25-30 April and the laying period started on 19-25 May (Dyrcz and Nagata, 2002). In spite of being a European country, Poland showed more similarity with Japan in terms of first laying and hatching dates (Dyrcz, 1995;Ezaki and Urano, 1995).…”

“…As soon as the birds arrived in the area of study at Poyrazlar Lake (Turkey), the breeding period started. In Japan and Poland, it started 20 days after the initial arrival (Dyrcz and Nagata, 2002). Poland is much closer to Turkey than to Japan, yet the breeding ecology of the Great Reed Warbler in Poland is more similar to that of Japan than that of Turkey.…”

“…All of the nests in Poland and Switzerland were built on reeds in water, as were the ones at Poyrazlar Lake (Turkey), but in Japan more than half of the nests were found in unflooded dry reed beds (Dyrcz and Nagata, 2002). The height of the nests from the water surface was higher in Japan (Kasumigaura Lake, 125.2 ± 27.2 cm) than in Turkey (Poyrazlar Lake 47.80 ± 3.93 cm) and Poland (Milicz Lake, 50.4 ± 18.5 cm).…”

Interactions between avian brood parasites, such as common cuckoos (Cuculus canorus), and their hosts are one of the best-studied examples of the coevolutionary arms race. Different stages of this arms race can be seen in different races of common cuckoos and their hosts across their range. However, little is known whether selected populations of two closely related but geographically distant species with probably different coevolutionary histories with the common cuckoo are also at different stages of the arms race. In this study, we tested this prediction experimentally using the same non-mimetic model eggs and three-dimensional (3D) printed models of the gray adult common cuckoo (Cuculus canorus). We examined egg recognition and egg rejection and aggression against the common cuckoo in the great reed warbler (Acrocephalus arundinaceus) and Oriental reed warbler (Acrocephalus orientalis), in Slovakia of Europe and northeast China of Asia. The results showed that the great reed warbler exhibited stronger responses to experimental model eggs and 3D models of the common cuckoo than the Oriental reed warbler. We conclude that both the great reed warbler and Oriental reed warbler have well-developed antiparasitic behaviors against common cuckoos in the studied populations, but with different levels of defense intensity, which may be due to local differences in parasitic pressure and the risk of parasitism.This provides an opportunity to study coevolutionary processes between the brood parasite and its hosts together in both species at large geographical scales.

Keeping eggs warm: thermal and developmental advantages for parasitic cuckoos of laying unusually thick-shelled eggs

Obligate brood parasites have evolved unusually thick-shelled eggs, which are hypothesized to possess a variety of functions such as resistance to puncture ejection by their hosts. In this study, we tested the hypothesis that obligate brood parasites lay unusually thick-shelled eggs to retain more heat for the developing embryo and thus contribute to early hatching of parasite eggs. By doing so, we used an infrared thermal imaging system as a non-invasive method to quantify the temperature of eggshells of common cuckoos (Cuculus canorus) and their Oriental reed warbler (Acrocephalus orientalis) hosts in an experiment that artificially altered the duration of incubation. Our results showed that cuckoo eggshells had higher temperature than host eggs during incubation, but also less fluctuations in temperature during incubation disturbance. Therefore, there was a thermal and hence a developmental advantage for brood parasitic cuckoos of laying thick-shelled eggs, providing another possible explanation for the unusually thick-shelled eggs of obligate brood parasites and earlier hatching of cuckoo eggs compared to those of the host.
