Winged Undertakers Digest the Deceased STORY and PHOTOS by LOWELL WASHBURN
nderrated and nappreciated Winged Undertakers Digest the Deceased STORY AND PHOTOS BY LOWELL WASHBURN 28 Iowa outdoors • JULY / AUGUST 2008 Although no one can for sure say why, turkey vultures have become increasingly common during the past two decades. Often referred to as “TVs” by birding enthusiasts, turkey vultures derive their name from the featherless, red heads of adults. And there’s no denying that, at least from a distance, a roosted vulture does somewhat resemble a male wild turkey. There’s good reason for the vulture’s distinctive, though ugly, bare head. As an avid consumer of carrion, TVs routinely forage in some pretty nasty places. The complete lack of head and neck feathers aids in maintaining cleanliness. Contrary to popular belief, vultures are among the cleanest of birds, spending up to four hours per day bathing and preening—more time than is documented for any other Iowa bird.

Turkey Vulture AKA: Turkey Buzzard, Buzzard, Vulture, Carrion Crow, Carrion Buzzard, Etc
Turkey Vulture AKA: Turkey Buzzard, Buzzard, Vulture, Carrion Crow, Carrion Buzzard, etc. Scientific Classification: Animalia, Chordata, Aves, Incertae sedis (disputed), Cathartidae; Cathartes; C. aura. Bird Size & Markings: Adult Turkey Vultures can be 32” long, stand 30” high and have 6 foot wingspans. Males and females have brownish-black body plum- age, silvery-gray flight feathers, bare red heads and a short yellow hooked bill. Turkey Vultures have very limited vocalization; it can only hiss or grunt. Habitat: The Turkey Vulture is the most abundant vulture in the Americas. It is commonly found in open and semi-open areas throughout the Americas from southern Canada to Cape Horn. It is a permanent resident in southern US States, though northern birds may migrate as far as South America. It prefers to roost on tall dead trees or high bare cliffs. It will roost on man-made structures such as water towers, skyscrapers, billboards and other structures of sufficient height. Nesting/Dens: There is little or no construction of a nest; eggs are laid on bare surfaces in protected locations such as a cliff, cave, burrow or inside a hollow A Turkey Vulture’s primary method of defence tree.

This deters most attackers (No doubt!). Food: Turkey Vultures prefer to feed on fresh carrion ranging in size from small mammals and dead fish to dead cattle and other grazers. They prefer fresh car- rion and avoid rotting carcasses. -

Temperature Regulation in Turkey Vultures

BERNSTEIN Department of Biology,New Mexico State University,Las Cruces,NM 88003 Abstract. Temperature regulation by six Turkey Vultures (Cathartesaura) was studied at ambient temperatures (T,) from 11 to 40°C in a metabolic chamber. Within this range body temperature varied little, averaging 39.7”C, and the ratio of CO, production to 0, consumption averaged 0.76. The thermal-neutral zone (TNZ) extended from 26 to 40°C. Below 26°C evaporative water loss and the heat-transfercoefficient were minimal, reflecting maximum insulation, and breathing and heart rates remained nearly constantat 10 and 142 min-I, respectively. Oxygen consumption increased by 12 ~1 0, STPD/(g hr) per “C of decreasein T, below 26°C so the percentageof metabolic heat lost by evaporation decreased from 22 to 13%. Within the TNZ 0, consumption was minimal, averaging 0.73 ml STPD/(g hr), but evaporation increased exponentially, dissipating metabolic heat to a maximum of about 90% at 40°C. Insulation decreasedexponentially within the TNZ. Despite this, however, the birds underwent rapid hyperthermia above 40°C. The likely explanation for this is that under the present experimental conditions the Turkey Vultures could not make use of important behavioral components of their thermoregulatoryrepertoire, including neck ex- tension, wing spreading,and urination on the legs. Were this not so they likely would have exhibited areater reduction in insulation and tolerated higher T.. The thermal relations of Turkey Viltures were similar to those calculated from allomeiric relations and to those measured previously in the closely related, partially sympatric Black Vulture (Coragyps atratus). -
The Reintroduction of Eurasian Griffon Monachus Vultures to France
Chancellor, R. D. & B.-U. Meyburg eds. 2004 Raptors Worldwide WWGBP/MME A Success Story: The Reintroduction of Eurasian Griffon Gyps fulvus and Black Aegypius monachus Vultures to France Michel Terrasse, François Sarrazin, Jean-Pierre Choisy, Céline Clémente, Sylvain Henriquet, Philippe Lécuyer, Jean Louis Pinna, and Christian Tessier ABSTRACT By the end of the 1960s, the future of vultures in France appeared bleak. Apart from the western half of the Pyrenees, with residual populations of Eurasian Griffon Gyps fulvus and Bearded Vultures Gypaetus barbatus, and Corsica with a few Bearded Vultures, most of France had lost its large vultures including the Black Vulture Aegypius monachus. Within the scope of a national conservation campaign, a process to restore raptor communities began. Concerning vultures, this was completed through reintroduction programmes. After the success of the Griffon Vulture reintroduction, started in 1968 in the Grands Causses of the Massif Central, other programmes followed in the 90s: Black Vultures in the Massif Central and then Griffon Vultures in the Southern Alps. In 2003 a viable population of Griffon Vultures in the Massif Central contained around 110 pairs. The same situation occurred in the Alps with about 50 breeding pairs of Griffon Vultures. Ten years after the beginning of the Black Vulture releases, the free ranging population included 11 breeding pairs. Accurate monitoring during the reintroduction period allowed us to estimate demographic parameters such as survival and breeding rates, evolution of breeding and foraging territories, main threats, movements between reintroduced populations and those from neighbouring countries, acceptance by people and the beneficial part played by vultures in what is called sustainable development. -

Competitive Interactions Within and Between Species in a Guild of Avian Scavengers
COMPETITIVE INTERACTIONS WITHIN AND BETWEEN SPECIES IN A GUILD OF AVIAN SCAVENGERS MICHAEL P. WALLACE AND STANLEY A. TEMPLE Departmentof WildlifeEcology, University of Wisconsin,Madison, Wisconsin 53706 USA ABSTRACT.--Weobserved Andean Condors(Vultur gryphus),King Vultures (Sarcoramphus papa),Black Vultures (Coragypsatratus), Turkey Vultures (Cathartesaura), and CrestedCara- caras(Polyborus plancus) interacting at 217 animal carcassesat two sitesin northern Peru. At 53 carcassesfor which we knew order of arrival, Turkey Vulturesusually arrived first, Black Vulturessecond, and condorsthird. On the basisof our observationsof 8,066 aggressive encountersbetween birds, we constructeddominance hierarchies by calculatingthe propor- tion of encounterswon by an individualof one species,sex, or age during encounterswith an individual of another species,sex, or age. Within each speciesthere was a positive rela- tionship between a bird's dominanceand its age. In condors,males dominatedfemales of the sameage.

Our partners were instrumental both in ensuring that we used the best available science to craft our analyses and recommendations in this 5-year review and in providing individual feedback that was used to refine this document. Photo Credit: Unless otherwise indicated, all photos, charts, and graphs are products of the U.S. Fish and Wildlife Service Page | 2 5-YEAR REVIEW California condor (Gymnogyps californianus) I. GENERAL INFORMATION Purpose of 5-Year Reviews: The U.S. Fish and Wildlife Service (Service) is required by section 4(c)(2) of the Endangered Species Act of 1973, as amended (Act) to conduct a status review of each listed species at least once every 5 years. The purpose of a 5-year review is to evaluate whether or not the species’ status has changed since it was listed (or since the most recent 5-year review). Based on the 5- year review, we recommend whether the species should be removed from the Lists of Endangered and Threatened Wildlife, changed in status from endangered to threatened, or changed in status from threatened to endangered. Our original listing as endangered or threatened is based on the species’ status considering the five threat factors described in section 4(a)(1) of the Act. These same five factors are considered in any subsequent reclassification or delisting decisions. -

Is the Black Vulture Migratory?
IS THE BLACK VULTURE MIGRATORY? EUGENE EISENMANN N a recent visit to Panama, while engaged in other studies, I observed 0 during many days in November 1962, groups of Black Vultures (Coragyps atratus) moving eastward, seemingly toward South America. These movements occurred both morning and late afternoon in the same direction, and the manner of flight was that characteristic of migrating rap- tars-high soaring in upward spirals alternating with long glides. I have failed to find any published report of observed group migration in this species. In most of the current literature the Black Vulture is stated, without qualification, to be “resident” within its vast breeding range from southern United States to Argentina and Chile (1957. A.O.U. Check-list of North American Birds; 1950. Friedmann et al., Pac. Coast Avif., 29:47). This is in contrast to the Turkey Vulture (Cathartes aura), which, although much less gregarious than the Black Vulture during the breeding season, is known to migrate in large flocks. C. W. Townsend (in Bent, 1937. U.S. Natl. Mus. Bull. 167:28) character- ized the Black Vulture as “a resident throughout its breeding range, except in the extreme northern parts,” adding that “a marked spring migration does not occur.” This might seem to imply autumnal migration, but the account failed to include any information as to migration, fall or spring. Most publications relating to eastern United States near the northern limit of the breeding range indicate that Black Vultures are present all the year, e.g., Maryland (Stewart and Robbins, 1958. N. Amer. Fauna, 62:106-107)) Ohio (Thomas, 1928. -
