About These Birds
Common Raven
큰까마귀는 가장 지능적인 조류 중 하나로, 도구 사용, 미래 계획, 복잡한 사회적 행동을 보인다. 전반적으로 광택 있는 검은 깃털을 가지며 북반구 전역의 다양한 서식지에 서식한다.
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
