Constraints on egg discrimination and cuckoo-host co-evolution
Article Abstract:
A study has been conducted to understand the mechanism of egg discrimination and rejection behaviour between the cuckoo, Cuculus canorus, and the great reed warblers, Acrocephalus arundinaceus. The results revealed a 61.5% rejection rate of cuckoo eggs by the warblers. They also showed that hosts highly reject non-mimetic eggs and eggs that look different from their own. The most common way of rejecting eggs was through egg ejection. A hypothesis explaining the mechanism of egg rejection and ejection is discussed.

Significance of social parameters on differential nutrient investment in guira cuckoo, Guira guira, eggs
Article Abstract:
A study is conducted to investigate how different facets of guira cuckoo sociality influence reproductive investment in eggs. The findings reveal that chicks that are smaller and lighter at hatching are victimized by infanticide significantly more than chicks that are heavier and bigger at hatching.

Differences in the nestling begging calls of hosts and host-races of the common cuckoo, Cuculus canorus
Article Abstract:
Comparisons were made between the nestling begging calls of four hosts and the host-races of the common cuckoo. Research has determined how differences in cuckoo begging could happen.
