Odocoileus hemionus columbianus
Odocoileus hemionus columbianusAlso known as Columbian Blacktail Deer, Black-tailed Deer, Pacific Blacktail
Columbian black-tailed deer browse through the misty coastal rainforests and brushy woodland edges of the Pacific Northwest. Recognized by their broad black-topped tails and large ears, these adaptable herbivores move silently through dense cover to forage on shrubs, lichens, and fallen acorns. Mothers hide cryptically patterned fawns in deep vegetation during early summer while stags develop velvet-covered antlers for autumn display battles.
