No.139 Black-crowned Night Heron Nycticorax nycticorax L=57cm Rank : 3
Resident

 Resident in small numbers.  Although we have recorded observations of more than ten birds at one time during our regular bird counts in downstream of Asakawa River in 1990s, only several birds have recently been recorded in a year. As its English name gNight Heronh suggests, the species is usually active at night, but we sometimes see the species flying during daytime. Juvenile: Dark brown, spotted and streaked with buff; called gHoshi Goih in Japanese meaning gStar-spangled Night Heron.h
