Scientists say they have captured photographs of one of the most mysterious known animals:bush dogs.


科学家说他们已经拍摄到了已知最神秘的动物之一:丛林狗的照片。


Bush dogs live in Central and South America.They are a rarely seen and threatened species.But the photos suggest they may be more common than scientists thought.


丛林犬生活在中美洲和南美洲。它们是一种罕见的濒危物种。但这些照片显示,它们可能比科学家们想象的更常见。


Scientists used cameras that take photos in the forest when an animal passes by.Photos of the bush dogs were taken in wild areas of Panama.The traps can be found across the country from its Costa Rican border to its border with Colombia.


科学家们使用照相机在动物经过森林时拍摄照片。这些丛林犬的照片是在巴拿马的野生地区拍摄的。从哥斯达黎加边境到哥伦比亚边境,这些陷阱遍布全国各地。

Ricardo Moreno is a research associate for the Smithsonian Institution.He and a team of biologists from Yaguará,Panama are studying large,wild mammals in that country.He says,"The bush dog is one of the rarest species that we photograph."


里卡多·莫雷诺是史密森学会的研究助理。他和一组来自巴拿马雅古拉的生物学家正在该国研究大型野生哺乳动物。他说:“丛林狗是我们拍摄的最稀有的物种之一。”


The researchers describe the animals as"short-legged and stubby,standing only about a foot(30cm)tall at the shoulder."


研究人员将这些动物描述为“短腿,矮胖,肩高只有一英尺(30厘米)”


Like other dogs,bush dogs hunt in packs of up to 10.They are known to communicate to each other using"high-pitched whines."They eat mostly large forest rodents.


和其他狗一样,丛林狗也会成群结队地猎食多达10只。众所周知,它们用“尖锐的呜咽声”相互交流。它们主要吃大型森林啮齿动物。


The bush dog is so elusive that photos of the animal were made only 11 times over 32,000 camera days.That is the number of cameras multiplied by the days in operation.


这只丛林犬非常难以捉摸,以至于在32000个拍摄日里,这只动物的照片只拍了11次。这是摄像机的数量乘以运行的天数。


The International Union for Conservation of Nature says bush dog populations have dropped by up to 25 percent over the past 12 years.It is considered a"near-threatened"species.


国际自然保护联盟说,在过去的12年里,丛林狗的数量下降了25%。它被认为是“濒临威胁”的物种。


Humans do not hunt or directly threaten bush dogs.But,habitat loss is affecting their numbers.They live mainly in rainforests.Scientists think the animals may require large forest spaces to survive.It is estimated that Panama lost 15 percent of its rainforest from 1990 to 2010.


人类不会捕猎或直接威胁丛林犬。但是,栖息地的丧失正在影响它们的数量。他们主要生活在雨林中。科学家认为这些动物可能需要大的森林空间才能生存。据估计,从1990年到2010年,巴拿马失去了15%的雨林。
