    The Four Keys to ID

    • Size & Shape

      Black-crowned Night-Herons are small herons with rather squat, thick proportions. They have thick necks, large, flat heads, and heavy, pointed bills. The legs are short and, in flight, barely reach the end of the tail. The wings are broad and rounded.
