My birdwatching note in Yokohama, other parts of Japan, Bhutan, Thailand and Asia.
Birdwatching in Shinjuku Gyoen (22 December 2013)
A pair of Baikal Teal was easily found in one of the ponds. According to local birdwatchers, they keep resting in the same place but sometimes come closer. Besides the teal, no other interesting bird was seen.
