What is the largest woodpecker?
The PileatedThe Pileated is our largest woodpecker. This is a black-and-white, crow-sized bird with a red crest. Males also have a red “mustache” stripe. You will recognize this bird at a distance due to its loud, harsh cry (“cuk-cuk-cuk”), large size, and undulating flight pattern as it flaps and swoops, flaps and swoops.
Why is the ivory billed woodpecker scarce?
The Ivory-billed Woodpecker was never a common bird, since it depended upon enormous, unbroken expanses of southern swamps providing the space and food it needed to thrive. Once its habitat began to disappear due to uncontrolled logging, the woodpecker became increasingly scarce. It was frequently shot by hunters and collectors, which likely contributed to its disappearance.

In 1935, Cornell professor Arthur A. Allen organized an expedition to the spot. The team included James Tanner, a graduate student, and bird artist George M. Sutton, an ornithologist and curator of the Cornell bird collection. After three days in the swamp, the team found an Ivory-billed Woodpecker nest. They set up camp and captured motion picture ...
What is the name of the woodpecker that has a long, barbed tongue?
Like all woodpeckers, the Ivory-billed had a strong, straight bill with a long, barbed tongue. An important feature of this bill was its tip, which was flattened laterally like a beveled wood chisel. The Ivory-billed Woodpecker used its strong bill to peel the bark off dead trees in search of insects, particularly the large wood-boring beetle grubs it favored. Its genus name, Campephilus, means "lover of grubs," alluding to its preferred diet.
What bird disappeared from the forest?

What is the color of the ivory billed woodpecker?
The plumage of the ivory-billed woodpecker is predominated by a shiny black or purple tint. There are white lines extending from the cheeks down the neck, meeting on the back. The ends of the inner primary feathers are white, as well as the whole of the outer secondary feathers. This creates extensive white on the trailing edge of both the upper- and underwing. The underwing is also white along its forward edge, resulting in a black line running along the middle of the underwing, expanding to more extensive black at the wingtip. Some birds have been recorded with more extensive amounts of white on the primary feathers. Ivory-bills have a prominent crest, although in juveniles it is ragged. The bird is somewhat sexually dimorphic, as seen in the picture to the right, as the crest is black along its forward edge, changing abruptly to red on the side and rear in males, but solid black in females, as well as juvenile males. When perched with the wings folded, birds of both sexes present a large patch of white on the lower back, roughly triangular in shape. Like all woodpeckers, the ivory-billed woodpecker has a strong and straight bill and a long, mobile, hard-tipped, barbed tongue. In adults, the bill is ivory in color, while it is chalky white in juveniles. Among North American woodpeckers, the ivory-billed woodpecker is unique in having a bill whose tip is quite flattened laterally, shaped much like a beveled wood chisel. Its flight is strong and direct, and has been likened to that of a duck.

What are ivory billed body parts?
Ivory-billed body parts, particularly bills, were sometimes used for trade, ceremonies, and decoration by various Native American groups from the western Great Lakes and Great Plains regions. For instance, bills marked with red pigment were found among grave goods in burials at Ton won Tonga, a village of the Omaha people. The bills may have been part of Wawaⁿ Pipes. Ivory-billed woodpecker bills and scalps were commonly incorporated into ceremonial pipes by the Iowa people, another Siouan-speaking people. The Sauk people and Meskwaki used ivory-billed body parts in amulets, headbands, and sacred bundles. In many cases, the bills were likely acquired through trade; for instance, Ton won Tonga was located roughly 300 miles from the farthest reported range of the ivory-billed woodpecker, and the bills were only found in the graves of wealthy adult men, and one bill was found in a grave in Johnstown, Colorado. The bills were quite valuable, with Catesby reporting a north–south trade where bills were exchanged outside the bird's range for two or three deerskins. European settlers in the United States also used ivory-bills' remains for adornment, often securing dried heads to their shot pouches, or employing them as watch fobs.
When did the ivory billed woodpecker return to nest?
Female ivory-billed woodpecker returning to nest, April 1935 , from the Singer tract expedition of Allen, Kellogg, Tanner, & Sutton. This bird was a member of the last universally accepted population of ivory-billed woodpeckers to be living in the United States.
How big are woodpeckers?
The ivory-billed woodpecker is one of the largest woodpeckers in the world at roughly 51 centimetres (20 in; 1.67 ft) long and 76 centimetres (30 in; 2.49 ft) in wingspan; it is the largest woodpecker in its range. The closely related imperial woodpecker ( C. imperialis) of western Mexico is the largest woodpecker in the world. The ivory-billed woodpecker has a total length of 48 to 53 cm (19 to 21 in), and based on scant information, weighs about 450 to 570 g (0.99 to 1.26 lb). Its wingspan is typically 76 cm (30 in). Standard measurements obtained include a wing chord length of 23.5–26.5 cm (9.3–10.4 in), a tail length of 14–17 cm (5.5–6.7 in), a bill length of 5.8–7.3 cm (2.3–2.9 in), and a tarsus length of 4–4.6 cm (1.6–1.8 in).

What is the kent call for ivory billed woodpeckers?
The typical call of the Ivory-billed Woodpecker is usually transliterated as a “kent.” In 1935, an expedition by the Cornell Laboratory of Ornithology to Louisiana’s Singer Tract (now the Tensas National Wildlife Refuge and the location of North America’s last undisputed Ivorybill sighting) captured the only universally accepted audio recordings of Ivory-billed Woodpecker vocalizations. This is a sonogram showing kent calls from the 1935 recordings.
What sounds are similar to ivorybill?
The harmonic structure of the Ivorybill call is similar to a wide variety of other sounds, both natural and mechanical. This complicates the process of distinguishing suspected Ivorybill vocalizations from potential confusion notes: squirrels, Blue Jays, nuthatches, and tree squeaks are among the most challenging. The challenges exist whether the reviewer is human (using mixed visual and auditory cues) or automated (using a visual pattern recognition algorithm), but we think we have been able to overcome some of them. The challenge is even greater when it comes to the Ivorybill’s “double knock” (equivalent to other woodpeckers’ drumming, see below), since anything from gunshots to raindrops can mimic the sounds’ visual pattern, and there are no undisputed recordings of Ivorybill double knocks. The remotely recorded sounds discussed in this post were found through a mixed visual and auditory review, with promising sounds first identified by sight.
Why do Ivorybills have double knocks?
We have also heard and recorded possible Ivorybill double knocks in response to anthropogenic double knocks (ADKs). Searchers perform ADKs in the field in hopes of generating a response or an attraction. Such events are rare because birds both have to be in earshot and be sufficiently stimulated to react or fly in. In other Campephilus woodpeckers, the double knock functions as a territorial display, so ADKs are an effective attraction tool. Since the available evidence suggests that even breeding Ivorybills do not defend their territories from other Ivorybills, the function of the double knock may be quite different when compared to South and Central American Campephilus woodpeckers. Thus, making inferences from the behavior of congeners is problematic, and ADKs may be less effective at generating a response or attracting a bird.
Where were ivorybill calls recorded?
In the early 2000s, apparent Ivorybill calls were recorded by Cornell Lab in Arkansas and by Auburn University and the University of Windsor in Florida.
Where was the last ivory bill sighting?

Who studied ivorybills?
James Tanner, the Cornell Lab researcher who studied Ivorybills in the 1930s and whose opinions had immense influence, did not find Reynard’s double knock recording convincing. He would have based this assessment on 30 year-old memories.
Do ivorybills drum?
Unlike most other woodpeckers, Ivorybills and others in the genus Campephilu s do not “drum” (although a few accounts in the literature suggest Ivorybills do). Instead of drumming, they communicate with “double knocks” (sometimes described as “double taps” or “double raps.”) Other than the recent searches, there is only one recording of a claimed Ivorybill double knock. This recording, which was associated with a sighting, was made by ornithologist George Reynard, in late 1960s in Texas.
