Bat Watching News Shinshu

NAZOKOE visit cherry blossom watching.

NAZOKOE is unknown bat in Japan. Maybe it is Tadarida insignis. We can hear the cruising pulse on our ear. Because its echolocation pulse is 10-20KHZ. NAZO means mystery, and KO-E is voice. This mysterious voice is heard at the ruins of Takato castle which is very famous for spring cherry blossom.
