蓝地鸠(Claravis pretiosa)是一种体长18-21厘米的小型鸠鸟；雄鸟淡蓝灰色，具深色翅斑；雌鸟暖褐色，具紫栗色翅斑。分布于从墨西哥到玻利维亚和巴西的湿润低地，以种子为食，栖息于竹林和茂密植被中。
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.
