Bar chart not displayed for this species; pond herons are only identifiable when they are in breeding plumage, so a bar chart would not offer a proper representation of this species's abundance at different times of the year.
This species can only be separated from Chinese and Indian Pond Herons when they are in breeding plumage, usually in April and May.
