Prahar dogs bark to alert each other to the presence of predators, with different cries depending on whether the threat is carried by air or approaching the ground.
But their warnings seem to help the weak herbal bird.
Curlews has discovered that if they are listening to warnings of the American wild dog colonies, they may get jumping on predators coming for them as well, according to the research published on Thursday in The Animal Behavior magazine.
“The Al Barari dogs in the list for every predator can think of the golden wins, red-tail hawks, foxes, budger, even large snakes,” said Andy Boyce, the research environment scientist in Montana at the National Animal Animal Animals Institute at the National Institute of National Animals of National Animals at the National Institute of National Animals for National Animals. Such animals are also a snack with pleasure on birds that nest herbal lands such as long Curlew, so the birds are adapted.
Previous research has shown that birds often listen to other bird types to receive information about food or danger sources.
However, so far, scientists have documented a few cases of birds that listen to mammals.
She said: “This does not necessarily mean that it is rare in the wilderness, as this means that we have not yet studied it.”
Prairie Dogs, a type of ground squirrel, lives in large colonies with a series of burrows that may extend underground miles, especially on the vast American plains. When they hear each other’s bark, they either stand on alert or dive into their burrows.
“This little bark is very high; it can carry a long way,” said Andrew Drillin, co -author of the field of research, who also works with Smithsonian.
Long nest Curlew in short grass and embrace eggs on the ground. When one hears the warning of the wild dog, she responds by pressing her head, beak and abdomen near the ground. Drillin said that in this winning position, “birds” depend on the amazing camouflage of their feathers to become irregularly on the plains.
The researchers created a fake predator by connecting the mummification of a mummification to a distance control, wrapped over the promoter in the north of the center of Montana towards the Curlew nests, sometimes in silence and sometimes while playing the recorded Bairie Dog Barks.
When the bark was played, Curlews retreated to the grass quickly, hiding when the Ghurair was about 160 feet. Without the bark, Al -Ghurair, who controls it, entered a distance about 52 feet of nests before it seems that Curlews feels dangerous.
