Generalist avian brood parasites vary considerably in their degree of host specialization (e.g., number of hosts); some parasitize the nests of just a few host species, whereas others exploit more than 100 species. Several factors, including habitat

Avian brood parasites such as Cuculus cuckoos are recognized to be affected more severely by the adverse effect of climate change owing to close host-parasite relationships. However, the spatial effect of climate change has rarely been assessed in th
