Yellow-crowned vs Black-crowned Night Heron: How to Tell Them Apart

Adults are easy: a Yellow-crowned Night Heron is gray all over with a black-and-white face, while a Black-crowned Night Heron has a black cap and back, gray wings and a white face and underparts. Young birds are the hard part. Both are brown and spotted, so look first at the spots: small on a young Yellow-crowned, large on a young Black-crowned. The bill helps too, mostly dark and heavy on the Yellow-crowned, thinner and partly yellow on the Black-crowned, but it is often muddy. In flight, look at the feet.

An adult Yellow-crowned Night Heron is gray all over, underparts included, with a glossy black head, a large white cheek patch and a white crown, washed pale yellow at the front. The back has a scaled pattern of black-centered feathers with pale gray edges. Its eyes are scarlet to orange-red, and long white plumes trail from the back of its head.

An adult Black-crowned Night Heron has a black cap, upper back and shoulders, gray wings, rump and tail, a white face and neck, and white to pale gray underparts, with red eyes and a stout black bill. Its white head plumes grow in the breeding season.

The two are about the same size: Yellow-crowned 21.6 to 27.6 inches (55-70 cm) long, Black-crowned 23 to 26 inches (58-66 cm). Both are shorter and stockier than most herons.¹

Juveniles of both species are brown above with pale spots and streaked below, and they are often confused. Four things help:

• The spots. A young Black-crowned has large pale spots on the back, shoulders and wing coverts. A young Yellow-crowned has smaller spots, especially on the wing coverts, and its brown has a grayer cast.² Its pale feather edges run into the small spots, giving a more mottled look.¹
• The bill. A young Yellow-crowned has a heavier, mostly dark bill; a young Black-crowned has a longer, thinner bill that is partly yellow. Don't rely on the bill alone: young birds' bills are often caked in mud.¹
• The legs and stance. A young Yellow-crowned has longer legs and stands more upright; the Black-crowned has a relatively short neck and legs.
• The streaks. The Yellow-crowned is more finely streaked below.

Both take three to four years to reach full adult plumage. In between, second-year Black-crowned look like dusky, darker adults, and second-year Yellow-crowned like dull, brownish adults with a muted head pattern.

Look at the feet. A flying Yellow-crowned Night Heron trails its feet and part of its legs well beyond the tail, and its wingbeats are slower. A Black-crowned shows only a short foot projection.³ This works on young birds too.

Both give a loud quawk. The Black-crowned's is guttural, often heard at night as birds fly over or when a colony is disturbed. The Yellow-crowned's is higher pitched, and it often calls a few seconds after taking off.

The Yellow-crowned is a crustacean specialist: crabs on the coast, crayfish inland. The Black-crowned is an opportunist whose diet is mainly fish and other water animals, but it takes almost anything, from insects and frogs to small mammals and refuse.

Timing differs too. The Black-crowned feeds mainly from evening to early morning, and by day when food demand is high, as in the breeding season. The Yellow-crowned feeds by day and by night.

No heron is more widespread than the Black-crowned, which breeds on all continents but Antarctica and Australia. The Yellow-crowned lives only in the Americas. In the lower 48 states, Black-crowned Night Herons live all year on both coasts and breed widely across the country, while the Yellow-crowned is found all year only in Florida and parts of the Southeast and breeds farther north in summer.^{1, 3} The Black-crowned uses almost any wetland, fresh, brackish or salt, including weedy pond margins, rice fields and canals; the Yellow-crowned keeps more to crab-rich coasts and crayfish streams.

They nest differently. Black-crowned Night Herons nest in tighter colonies, often under 10 feet (3 m) between nests, and tend to avoid nesting close to houses. Yellow-crowned Night Herons often nest alone or in loose groups, and many choose wooded neighborhoods.³

Which is more common?

The Black-crowned. Partners in Flight estimates about 3,000,000 Black-crowned Night Herons against about 400,000 Yellow-crowned.⁴

Can they hybridize?

Yes: the two have hybridized in the wild, even though they belong to different genera and are less closely related than once thought.³

What else looks like a young night heron?

An American Bittern. It has a long, dark mark down the side of the neck and lacks the large pale spots.
