内容简介
In Helpers at Birds' Nests, renowned naturalist and ornithologist Alexander Skutch provides vivid, detailed accounts of a remarkable aspect of bird behavior -- the aid that one bird gives another who is neither its mate nor its dependent young and who may even belong to a different species.In graceful, clear prose, Skutch makes accessible to amateur bird-watchers examples of cooperation in species as far-flung as the little rifleman of New Zealand, the Laysan albatross in the mid Pacific, and the neotropical birds of Skutch's own Valley of El General in Costa Rica.
