Ivory-Billed Woodpecker Fact Sheet Ivory-Billed Woodpecker Fact Sheet Common Name: Ivory-Billed Woodpecker Scientific Name: Campephilus principalis Wild Status: Critically Endangered - heavily believed to be extinct Habitat: Pine Forests, thick hardwood swamp areas Country: Southeastern United States, and a subspecies native to Cuba Shelter: Trees Life Span: Unknown - some speculate up to 20 years or more Size: Weighs about 1 pound on average, total length roughly 20 inches, with a typical 30 inch wingspan Details The Ivory-Billed Woodpecker is a very rare bird, native to the Southeast of the United States. They are one of the largest woodpeckers in the world, and noticeable by their distinct black and white pattern and red plumage near their head. Primarily due to habitat loss, as well as hunting to a lesser extent, the Ivory-Billed Woodpecker is classified as critically endangered. However, many associations and biologists believe the species to be functionally extinct, as true sightings and evidence of living specimens has not been published in over 10 years. The Ivory-Billed Woodpecker is believed to mate for life like many birds, and both parents would work together to create a nest for the young. Much of the woodpecker's diet consists of larvae and insects, as well as seeds and fruit. Cool Facts • They are sexually dimorphic - only the males have the red plumage on their head. • Four distinct vocal calls were noted in literature, and two of these calls were recorded in the 1930s. • While many unconfirmed reports still come in, this species was assessed as extinct in 1994. However, this was later altered to critically endangered on the belief that the species might have relocated from their native habitat. • The search for a living specimen has led to a small tourism boost in areas like Arkansas in the woodpeckers native range. There have even been attempts at a woodpecker festival and woodpecker hairstyle to bandwagon off of the animal's mysterious popularity. • Many nicknames have been created for the Ivory-Billed Woodpecker, including "grail bird", "King of the Woodpeckers", and "Elvis in feathers". Taxonomic Breakdown Kingdom: Animalia Phylum: Chordata Class: Aves Order: Piciformes Family: Picidae Genus: Campephilus Species: C. principalis Conservation & Helping Officially, the Ivory Billed Woodpecker is listed as Critically Endangered by the IUCN. However there has been a lot of debate over whether this species is actually extinct or not, as no definitive proof via videos, DNA, feces, or any other specimen has been published in over 10 years. Habitat loss and destruction in their native forests are the biggest reasons why the Ivory Billed Woodpecker has lost most, if not all, of their population.

  • Periodic and Transient Motions of Large Woodpeckers Michael D
    www.nature.com/scientificreports Correction: Publisher Correction OPEN Periodic and transient motions of large woodpeckers Michael D. Collins Two types of periodic and transient motions of large woodpeckers are considered. A drumming Received: 3 July 2017 woodpecker may be modeled as a harmonic oscillator with a periodic forcing function. The transient Accepted: 12 September 2017 behavior that occurs after the forcing is turned of suggests that the double knocks of Campephilus Published: xx xx xxxx woodpeckers may be modeled in terms of a harmonic oscillator with an impulsive forcing, and this hypothesis is consistent with audio and video recordings. Wingbeats are another type of periodic and transient motion of large woodpeckers. A model for the fap rate in cruising fight is applied to the Pileated Woodpecker (Dryocopus pileatus) and the Ivory-billed Woodpecker (Campephilus principalis). During a brief transient just after taking of, the wing motion and fap rate of a large woodpecker may not be the same as in cruising fight. These concepts are relevant to videos that contain evidence for the persistence of the Ivory-billed Woodpecker. Drumming and wingbeats are two types of periodic motion of large woodpeckers. Tis paper discusses these behaviors and related transient motions that occur in evidence for the persistence of the Ivory-billed Woodpecker (Campephilus principalis)1–3. Most woodpeckers signal by drumming, which consists of a rapid series of blows with the bill. Audio S1 contains four drumming events by nearby and distant Pileated Woodpeckers (Dryocopus pileatus). Some members of the Campephilus genus do not engage in this type of drumming but instead signal with double knocks.

  • Anatomical Evidence for Phylogenetic Relationships Among Woodpeckers
    ANATOMICAL EVIDENCE FOR PHYLOGENETIC RELATIONSHIPS AMONG WOODPECKERS WILLIAM R. GOODGE ALT•tOUCr•the functionalanatomy of woodpeckershas long been a subjectof interest,their internal anatomyhas not been usedextensively for determiningprobable phylogeneticrelationships within the family. In part this is probablydue to the reluctanceto use highly adaptivefea- tures in phylogeneticstudies becauseof the likelihood of convergent evolution. Bock (1967) and othershave pointedout that adaptivehess in itself doesnot rule out taxonomicusefulness, and that the highly adaptivefeatures will probablybe the oneshaving conspicuous anatomical modifications,and Bock emphasizesthe need for detailedstudies of func- tion beforeusing featuresin studiesof phylogeny.Although valuable, functionalconclusions are often basedon inferencesnot backed up by experimentaldata. As any similaritybetween species is possiblydue to functionalconvergence, I believewhat is neededmost is detailedstudy of a numberof featuresin order to distinguishbetween similarities re- sultingfrom convergenceand thosebased on phylogenticrelationship. Simplestructures are not necessarilymore primitive and morphological trendsare reversible,as Mayr (1955) has pointedout. Individual varia- tion may occur and various investigatorsmay interpret structuresdif- ferently. Despite these limitations,speculation concerning phylogeny will continuein the future,and I believethat it shouldbe basedon more, rather than fewer anatomical studies.

  • Detailed Species Account from the Threatened Birds of the Americas
    IVORY-BILLED WOODPECKER Campephilus principalis E/Ex4 The North American population of this large, low-density woodpecker is very probably extinct, and the most recent evidence suggests that there is almost as little hope for the Cuban form, which was last reported in 1987 or 1988 with glimpses in 1991, despite much intensive searching in the Sierra de Moa, the area to which it finally retreated in the course of this century; destruction of its virgin forest habitat, of which each pair evidently needed very large amounts, is chiefly to blame for the loss of the species. DISTRIBUTION The Ivory-billed Woodpecker formerly occurred throughout the south-east U.S.A. (nominate principalis) and Cuba (race bairdii; see Remarks 1), but is now virtually or actually extinct in both countries, although evidence for its survival in Cuba is far more recent; for this reason, the following account principally treats the Cuban form, the North American race being judged probably extinct and not to be covered in detail here. U.S.A. Ivory-bills once ranged through the south-east of the country from south-east North Carolina, southern Kentucky, Illinois, Missouri, Arkansas and Oklahoma to the coast of the Gulf of Mexico and the Florida peninsula, with populations disappearing (as a result of forest destruction, but compounded by commercial collecting, which eliminated certain populations) from the northern and western extremities of its range before 1885, from most of Missouri, Arkansas, Mississippi and Alabama between 1885 and 1900, and from most of Florida, eastern Texas and Louisiana by 1930 (King 1978-1979).

  • Dew-Bathing in the Atlantic Forest Endemic Robust Woodpecker Campephilus Robustus (Lichtenstein, 1823) (Aves: Picidae)

An unusual observation of the Atlantic Forest endemic Robust Woodpecker Campephilus robustus dew-bathing socially is reported from Paraguay and discussion of its significance follows. Dew-bathing has been reported for a small number of New World bird families and has often been linked to a shortage of water, but has never been previously reported in New World Picidae. Given the environmental conditions in this humid habitat it is considered that dew-bathing in this family is related to structure and ecological constraints and not to limited access to water. Picids are highly arboreal birds with structural modifications for arboreality that make them awkward and thus potentially vulnerable when on the ground. A propensity for dew-bathing in forest canopies at sunrise may be a factor in the rarity of such observations and contribute to the lack of published reports.

Hill1, Daniel J. Mennill2, Brian W. Rolek1, Tyler L. Hicks1, and Kyle A. Swiston2 ABSTRACT. The Ivory-billed Woodpecker (Campephilus principalis) disappeared from the forests of southeastern North America in the early 20th Century and for more than 50 years has been widely considered extinct. On 21 May 2005, we detected a bird that we identified as an Ivory-billed Woodpecker in the mature swamp forest along the Choctawhatchee River in the panhandle of Florida. During a subsequent year of research, members of our small search team observed birds that we identified as Ivory-billed Woodpeckers on 14 occasions. We heard sounds that matched descriptions of Ivory-billed Woodpecker acoustic signals on 41 occasions. We recorded 99 putative double knocks and 210 putative kent calls. We located cavities in the size range reported for Ivory-billed Woodpeckers and larger than those of Pileated Woodpeckers (Dryocopus pileatus) that have been reported in the literature or that we measured in Alabama. We documented unique foraging signs consistent with the feeding behavior of Ivory-billed Woodpeckers.

Crimson-crested woodpecker, Campephilus melanoleucos. [http://www.oiseaux.net/photos/michel.giraud-audine/pic.de.malherbe.1.html#monde, downloaded 7 November 2012] TRAITS. One of the largest woodpeckers ranging from 33–38 cm in length and 180-285 g in weight (Wikipedia, 2012). This species is easily distinguishable by its bright red crest and sides of the head. Campephilus melanoleucos males and females have all black plumage on their backs. Adult males have a red line tracing from their bills to their throats. Adult females show a UWI The Online Guide to the Animals of Trinidad and Tobago Behaviour black forecrown with broad white stripes across the sides of their heads. White lines run down the sides of the black throats of both sexes and trail along their shoulders to meet in a “V” on their backs. In flight both sexes show white in their wings. Juvenile males are similar in appearance to adult females with the exception of red on the side of the head. Bill colour is dark gray with a paler gray at the base. Tarsi and toes are pale green or brownish gray (Wetmore, 1968, in Kilham, 1972). One account of sexual dimorphism in iris color was documented in Venezuela, 1 female with iris red, 2 males with iris yellow (Willard, et al. 1991, in Neotropical Birds Online, 2012). In both sexes wing length averages 184 mm, tail length averages 109 mm, tarsus length averages 37 mm (Wetmore, 1968, in Kilham, 1972).
