Birdist Rule #83: Identify Your First Ibis

Beware: We have three species, and two of them can be really confusing.

The first time I ever saw an ibis was in third grade when we were studying the ancient Egyptians. There were all kinds of cool animals depicted as gods in the hieroglyphics: falcons, owls, crocodiles, cats and . . . 听a small-headed, long-billed, bird-type thing that I didn鈥檛 recognize and had a funny name: 鈥淚bis.鈥澨齆ext to those other gods, I thought, this one wasn鈥檛 quite as impressive.

I didn鈥檛 even know we had ibis in this country until I was a birder,听let alone three different species. They are the听White Ibis, Glossy Ibis, and White-faced Ibis, and they range throughout the U.S. Depending where you live, I听recommend you pick one, go find it, and then decide for yourself if they鈥檙e a worthy deity.

No matter听which species you鈥檙e after, the best place to start is a wetland. Related to herons and storks, ibis are aquatic waders that feed by probing mud and soil for little water-based goodies. Their听relatively large size (about that of Snowy Egret or night-heron) and long, thin, down-curved bill is enough to separate an ibis from just about any other bird. (Except maybe a Long-billed Curlew, but they鈥檝e got like reeeallly long, thin bills, and are big and brown in a way that ibis aren鈥檛.)

But once you鈥檝e got an ibis, how do you know which one you鈥檙e looking at? Well, that's why we're here.听Let鈥檚 start with the White Ibis, because it is by far the easiest to identify.

White Ibis are one of those birds in the field guide that are just labeled 鈥渦nmistakeable.鈥 Such proclamations tend to make me nervous (I can usually find a way to screw up an ID), but White Ibis are a pretty safe bet. About the size of a duck on stilts, White Ibis are white (duh) with bright red legs and a bright red bill. Adults have black wing tips that are clearly evident in flight. It鈥檚 a pretty bird.

Juvenile White Ibis are a little trickier, with a brownish back, bill, and neck. But the white underwings and rump are a giveaway that you鈥檙e not looking at anything else.

White Ibis are common in Florida and along the Gulf and Carolina coasts. In fact, White Ibis have elevated to a god-like status in听South Florida. Rather than in hieroglyphics, though, these birds are worshipped on the football field听as the official mascot for the听University of Miami Hurricanes. Apparently, the students听听that the White Ibis is 鈥渒nown for its bravery as a hurricane approaches鈥 and 鈥渦ses its instinct to detect danger,鈥 being the last of the wildlife to take shelter when a storm hits and the first to emerge when it鈥檚 over.

That is . . .听uh . . .听That is all听hooey. White Ibis aren鈥檛 any better or worse than any other species at protecting themselves from hurricanes, and the most definitely aren't, as the University of Miami claims, a bird that 鈥渙ther birds look to for leadership.鈥 Still, I love to see the fighting White Ibis mascot named听听on the sidelines, even if the听costume is听an听.

Our other two ibis species, Glossy and White-faced, aren't as revered as the White Ibis, but they still deserve our听respect鈥攁nd an extra close look. These two听species are听strikingly similar in appearance, and they can be difficult to separate without a thorough听inspection.

Fortunately, mixing the two up is often听easy to avoid because their ranges are mostly separate听(they both breed on the Gulf Coast and wander into the Midwest).听The White-faced Ibis is the more widespread of the two, breeding regularly throughout the West. The Glossy Ibis听is an Atlantic Coast species found from听Maine to Florida听and frequently along the Gulf Coast to Louisiana. That said, you need to be prepared: Wayward individuals of both species regularly show up in each others鈥 ranges, so every birder should know how to tell them apart.

The bodies, as lovely as they are, aren鈥檛 going to help you. Both of these species have shiny green and purple plumage that, like European Starlings, can look kinda dingy until it catches the right light. When it does it鈥檚 stunning, like a little oily rainbow. Appreciate that, and then move on.听

The key to identifying these birds is in the face. You鈥檝e probably pieced together by now that the White-faced Ibis has a white face, but that's not really helpful听because the Glossy Ibis听also听has white in its face. Or, at least, bluish听white. The pale markings on the face can be confusing, so to nail the ID听you have to keep looking.

Both species have bare skin on the face, between the eye and the bill, surrounded by normally feathered areas. Breeding White-faced Ibis have a broad band of white feathers surrounding the bare facial skin, and that skin is bright pink, encircling a red eye. Glossy Ibis have no white on the feathers of the face: instead, the border of the facial skin is a very听pale blue听in breeding season, and the rest of the bare skin is dark gray, encircling a dark eye.

Nonbreeding birds are tougher. The White-faced will lose its rim of white feathers and the bright pink skin will turn dull red, but it will retain a deep red eye. (Two of them, in fact.) Alternatively, Glossy Ibis have dark eyes and gray facial skin in all plumages. First winter birds of both species are a real challenge, and are maybe best left identified as 鈥渋bis species.鈥 No one will mind.听

Since I first discovered the听ibis all those years ago,听听that the ibis-headed deity, named Thoth, was the God of Knowledge, the Moon, Measurement, Wisdom, the Alphabet, Records, Thought, Intelligence, Meditation, the Mind, Logic, Reason, Reading, Hieroglyphics, Magic, Secrets, Scribes, and Writing. My goodness, that鈥檚 a lot of responsibility! American ibis species might听not be quite as powerful as all that, but don't let that stop you from getting out there to find one of these special birds.听
