Black-tailed deer (Odocoileus hemionus columbianus) discharge an odor from the metatarsal (MT) gland, located on the hindleg, when disturbed or alarmed. Freely moving, captive deer were exposed to the MT odor by means of a remote-release apparatus. Responses by males and females to MT odor from both sexes were recorded with a coding system and a video camera. When the odor was present, females became more alert and left the site more often than in the presence of control odors, odorless air, or deer urine. It is concluded that the MT secretion provides an alert signal, placing the odor into the class of alarm pheromones. There is no evidence that the closely related white-tailed deer,O. virginianus, possesses this alert (or alarm) odor system to the same degree.
黑尾鹿（Odocoileus hemionus columbianus）在受到干扰或警报时会从后腿的跖腺（MT）分泌出气味。通过远程释放装置，自由活动的圈养鹿会接触到 MT 气味。雄性和雌性对来自两性的 MT 气味的反应通过编码系统和摄像机进行记录。当有气味时，雌性比在有对照气味、无味空气或鹿尿时更加警觉，离开现场的次数也更多。因此可以得出结论，MT 分泌物提供了一种警报信号，将气味归入警报信息素的类别。没有证据表明亲缘关系密切的白尾鹿（O. virginianus）具有同样程度的这种警报（或警报）气味系统。
