<p>Some animals weep out of sorrow or stress, similar to human baby cries, according to animal behaviour experts.<br /><br /></p>.<p>The question whether animals are capable of crying emotionally has been raised again after media reports last week described a crying newborn elephant calf at Shendiaoshan Wild Animal Nature Reserve in eastern China.<br /><br />The calf reportedly cried inconsolably for five hours after being stomped on by his mother.<br />"Some mammals may cry due to loss of contact comfort," said animal behaviourist Marc Bekoff.<br /><br />"It could be a hard-wired response to not feeling touch," added Bekoff, former professor of ecology and evolutionary biology at the University of Colorado, Boulder.<br /><br />For elephant calves and human infants, crying is probably more out of stress than sorrow, he told 'Discovery News'.<br /><br />He pointed out that scientific studies have proven that chicken, mice and rats display empathy - feeling another's pain - which is an even more complex phenomenon.<br />For crying, the animal would have to be of a social nature, possess eye anatomy similar to ours, and have brain structure for processing emotions.<br /><br />Dogs are among the most social animals, but scientists and owners have yet to report on a depressed dog crying its eyes out.<br /><br />"However, dogs and other animals certainly can suffer and may recognise suffering in others," said Brian Hare, an associate professor of evolutionary anthropology at Duke University who co-founded a dog analysis tool "Dognition".<br /><br />In a questionnaire on the Dognition site, 72 per cent of owners reported that their dog suffers from mild to extreme separation anxiety, likely similar to what the elephant calf felt.<br /><br />"This anxiety is manifested as whimpering, whining and howling when the dog is separated from a loved one. So dogs may not cry with tears, but they certainly can cry with vocalisations to say they are anxious, stressed or lonely," Hare said.</p>
