What is the species of this all-white heron?
Yellow-crowned Night Heron
Nope, bill is too thick, eye too big, and Cattle Egret should have black legs
Little Blue Heron (immature)
No, bill is a little too thick, and Little Blue should have greenish-gray legs and bill, not yellow.
Sorry, Great Egret would be much more slender, and have black legs.
Great Blue (Great White) Heron
No, "Great White" Heron would be much more slender, and have drabber grayish legs and bill
Nope, Snowy Egret is more slender and has black or greenish legs, dark bill
Question 1 Explanation:
It's an albino Yellow-crowned Night Heron, identified by size and shape. The lack of melanin has left the bill and legs bright yellow, instead of the usual dark gray, but the eye color is not affected. The thick bill, large orange eye, moderately long and thick neck, and other clues all fit Yellow-crowned and no other heron.
There is 1 question to complete.
