Black Swan Family
1st image: A Black Swan Family: the male (cobbe), female (pen), and chick (cygnet) were swimming peacefully until another male, from across the lake, invaded their territory and caused a brisk, but brief, fight between himself and the resident cobbe. (Please see next image for the conclusion of the fight). [Blue Lake (Lake Tikitapu), near Rotorua, North Island, New Zealand].
