Nowadays, I'm sure the matching of two pairs and not sure for the another two or three pairs of the Eastern Sarus Crane at Sanambin because some pair, they have to change a partner. For this year, we were released the twelve juvenile cranes add to the Sanambim and found a new problem of some cranes flew away in long distance immediately because they had a short period of acclimation (about one month). This problem is result to the difficult to the monitoring process. The reason of the short acclimation period from the cause of the permit from Department of National Park, Wildlife and Plant Conservation have very delays.
