what time of year do ravens lay eggs
Common raven In most of their range, egg laying begins in late February. In colder climates, it is later, e.g. April in Greenland and Tibet. In Pakistan, egg-laying takes place in December.[48] Eggs and hatchlings are preyed on, rarely, by large hawks and eagles, large owls, martens and canids. The adults, which are very rarely preyed upon, are often successful in defending their young from these predators, due to their numbers, large size and cunning.[69] They have been observed dropping stones on potential predators that venture close to their nests.[74]
