Figure 1: Eggs laid by hosts of the brood parasitic common cuckoo. Thus, SIFT evaluates patterns in a way that is neurobiologically plausible, not just for primates but also for birds, providing a ...

European cuckoos lay very different eggs depending on the host species. Genetic analyses have revealed how this adaptation is inherited without leading to speciation. Subscribe to our newsletter for ...

New research reveals how biological arms races between cuckoos and host birds can escalate into a competition between the host evolving new, unique egg patterns (or "signatures") and the parasite new ...
