摘要：

We report an incident of a Common Raven (Corms corax) taking an egg from an active Common Loon (Gavia immer) nest. and two other possible similar events. The fact that ravens can take whole eggs, leaving no trace of eggs on the nest, could explain a considerable proportion of the missing loon eggs that researchers have documented, particularly on lakes with few humans.
