Agitated Black-crowned Night Herons

“I was at Sugei Tampines in Pasir Ris on 5th June 2010 at 9am when I saw a group of Black-crowned Night Herons (Nycticorax nycticorax) perched on the same tree in the open which is very strange because normally they are quite solitary birds and prefer to perch hidden in the bushes.

“Some distance away, a huge flock of crows were chasing a few Grey Herons (Ardea cinerea) and this might have agitated the night herons. Several times, lots of night herons will suddenly start flying around when the crows start provoking the Grey Herons which in turn will agitate the night herons. I estimated spotting about 12 night herons at one time, some flying and some perching.”
