Herons
Color changes with age; proportion, legs, and behavior usually last longer.
Reviewed:Not every white heron is the same.
Wetlands, mangroves, salt flats, channels, and coasts gather several herons. Compare height, neck, bill, and legs with vegetation or other birds before chasing color.
Juvenile Little Blue Heron is white and young night-herons are streaked. Date, posture, and feeding technique prevent reliance on one mark.

01
White herons: size, bill, and feet
Great Egret is tall with a yellow bill; Snowy Egret is smaller with dark bill and yellow feet; Cattle Egret has a short neck and often uses pasture.
White juvenile Little Blue Heron shows a two-toned bill and greenish legs. Follow behavior for several minutes to add evidence.
02
Night-herons and active hunters
Adult Black-crowned Night-Heron has a dark crown; Yellow-crowned has a stronger face. Juveniles require bill, proportion, spots, and habitat, or must remain night-heron.
Reddish Egret runs and shades water with its wings; Tricolored is slim with a pale belly. Repeated behavior is worth more than one pose.
