Study on vocal behavior of dholes (Cuon alpinus) and training for observation of wild dholes
Date:2010/10/28 - 2010/12/28
The dhole (Cuon alpinus) is a canid species hunting in packs living in India, China and Southeast Asia.
It is classified as an endangered species by IUCN.
Dholes have been reported to produce many types of calls in several situations both in wild and captivity and probably communicate with these calls.
However, the function(s) of the calls is not known yet.
I have studied dholes in Japanese zoos since 2010.
In order to estimate the function(s) of each call types, I plan to observe the behavior of wild and captive dholes in India and analyze relationship between the call types and behavior.
This time, I visited Arignar Anna Zoo in Chennai, Tamil Nadu state, Mudumalai National Park, Tamil Nadu state, in India and Singapore Zoo in Singapore for preliminary research and training for the study of wild dholes.
I video-recorded the behavior and calls of captive dholes at Arignar Anna Zoo and Singapore Zoo.
I also observed and video-recorded wild dholes at Mudumalai National Park.
