迟滞可能会被鸟类传播，但鸟类与迟滞之间的相互作用程度几乎是未知的。我们在智利纳瓦里诺岛安第斯高原冻土带采集的白腹燕麦(Attag Is Malouinus)粪便中发现了9种迟缓虫。其中八个迟滞样本一旦重新水化就开始移动。2个标本属于Adropion属(Hypsibiidae)，1个属于MacroBiotus(MacroBiotidae)，5个标本无法鉴定。第九个标本是一种处于胚胎卵状状态的异尖线虫。这些迟滞可能在偶然摄入后通过禽类的消化道，或者在排便后进入粪便中，以粪便中存在的微生物和未消化的植物物质为食。据我们所知，这是首次在鸟类粪便中发现迟滞，如果鸟类内源性运输迟滞，可能会对迟滞的分布产生影响。
Tardigrades are potentially dispersed by birds, but the extent of the interactions between birds and tardigrades is virtually unknown. We discovered nine tardigrades within feces of White-bellied Seedsnipe (Attagis malouinus) collected from high Andean tundra on Navarino Island, Chile. Eight of the tardigrade specimens began moving once rehydrated. Two specimens belonged to the genus Adropion (Hypsibiidae), one to the Macrobiotus (Macrobiotidae), and five could not be identified. A ninth specimen was a species of Isohypsibius in an embryonic egg state. These tardigrades could have passed through the avian digestive tract after incidental ingestion or burrowed into the feces post-defecation to feed on microorganisms and undigested plant matter present in the feces. To our knowledge, this is the first discovery of tardigrades in bird feces and may have implications for tardigrade distributions if birds transport tardigrades endogenously.
