灰旱獭(Marmota baibacina)是严格家族群居昼间活动的大型啮齿动物,多数情况下都不离开自已的领地,对构成威胁的因素大都采取躲避方式。据多年观察,旱獭一般喜欢晒太阳,在洞外食草喜耍,未发现过早獭与异种动物争斗。我们在鼠疫监测工作中,却发现了旱獭的两个有趣的生态行为。 Marmota baibacina is a large rodent living strictly during the daytime and does not leave its own territory in most cases. Most of the factors that pose a threat are evasion methods. It has been observed for many years that marmots generally like to sunbathe and enjoy grass grazing outside the cave. No marmot has been found to fight heterosexuals. During the plague surveillance, we found two interesting ecological behaviors of marmots.
