Field Identification of the Field Identification of the Field
TOPICS IN IDENTIFICATION he Solitary Eagle ( Harpyhaliaetus solitarius ) is a large raptor that is closely related and similar in adult and immature plum- Tages to the black-hawks in the genus Buteogallus (Lerner and Mindell 2005). It is a rare and very local resident in a variety of wet and dry forested hills and highlands from northern Argentina to northern Mexico (del Hoyo et al. 1994, Ferguson-Lees and Christie 2001). The species has been collected in Mexico not far from the Texas border (see Discussion, pp. 72 –73), so it is possible that it has occurred in the ABA Area. The handful of specimens and nest records of this eagle are from 700 to 2,000 meters above sea level (Brown and Amadon 1968).

Reproduction and Behaviour of the Long-Legged Buzzard (.Buteo Rufinus) in North-Eastern Greece
© Deutschen Ornithologen-Gesellschaft und Partner; download www.do-g.de; www.zobodat.at Die Vogelwarte 39, 1998: 176-182 Reproduction and behaviour of the Long-legged Buzzard (.Buteo rufinus) in North-eastern Greece By Haralambos Alivizatos, Vassilis Goutner and Michael G. Karandinos Abstract: Alivizatos , H., V. Goutner & M. G. Karandinos (1998): Reproduction and behaviour of the Long- legged Buzzard ( Buteo rufinus) in North-eastern Greece. Vogelwarte 39: 176-182. The breeding biology of the Long-legged Buzzard ( Buteo rufinus) was studied in the Evros area, north-eastern Greece in 1989, 1990, 1992 and 1993. The mean number of young fledged per pair per year was similar between years with an overall average of 0.93 (1.58 per successful pair). Of ten home range variables examined, the num ber of alternative nest sites and the extent of forest free areas in home ranges were significant predictors of nest ling productivity. Aggressive interactions were observed with 18 bird species (of which 12 were raptors), most commonly with the Buzzard {Buteo buteo). Such interactions declined during the course of the season. Prey pro visioning to nestlings was greatest in the morning and late in the afternoon declining in the intermediate period. Key words: Buteo rufinus, reproduction, behaviour, Greece.

Species List for Svalbard Birds and Mammals
Falkland Islands Circumnavigation – A South Atlantic bird & wildlife spectacle Falkland Islands There is no other groups of islands in the entire Atlantic Ocean which allows fairly easy access to such a diversity of spectacular bird species under such a mild climate and with such a variety of marine mammals thrown in. The Falkland Islands are known to most people today more for their recent political history than their natural history. And even to many nature lovers, the Falklands are often seen as secondary compared to the neighbouring Antarctica and South Georgia. This voyage aims to set the record straight: The Falkland Islands are worth every minute of a two-week circumnavigation, and they will provide us with a long string of wonderful encounters with penguins (4-5 species), albatrosses, cormorants, ducks and geese, raptors, shore birds, song birds and more – as well as seals and sea lions, whales and dolphins. We will see a variety of the islands’ unique landscapes of rolling hills, stone runs, rugged shorelines, pristine white beaches and lush giant kelp beds. We will see the endemic bird species and several near-endemic ones as well, and we intend to visit the southern hemisphere’s largest albatross colony on Steeple Jason. There will be time enough to allow for prolonged visits to the most magnificent of the sites during the best of the weather conditions. The group will be small enough to allow for great flexibility and individual attention. Tour Description Dates: December 3 - 17, 2016. Price: Starting at US$ 8.500,- Group size: Minimum 8, maximum 11. -
The Morphology of the Bill Apparatus in the Steller's Sea Eagle
First Symposium on Steller’s and White-tailed Sea Eagles in East Asia pp. 1-10, 2000 UETA, M. & MCGRADY, M.J. (eds) Wild Bird Society of Japan, Tokyo Japan The morphology of the bill apparatus in the Steller’s Sea Eagle Alexander Ladyguin Moscow State University, Science Park, Educational-Research Center "Ecosoil", 119899, Moscow, Russia. e-mail: [email protected] INTRODUCTION The osteology of birds has been more thoroughly investigated than any other anatomical system in that group of animals. Being made up of many individual parts, each with numerous details, the skeleton offers more evident possibilities for study than other systems. Bones also make up most of the fossil evidence. The avian skull and mandible have featured largely in systematic accounts (e.g. Huxley 1867, Pycraft 1898, Barnikol 1952, Fisher 1944), and have attracted much attention as to function (e.g. Lakjer 1926, Hofer 1950, Bock 1970, Dzerdjinskiy 1972, 1986, Hertel 1994). Study of the avian skull rests in part on research during developmental stages, as in the adult few suture lines are retained. Some phases of development have been investigated by Parker 1890, Marinelly 1936, Jollie 1957, Sushkin 1899, 1902. Some species of Falconiformes were investigated by Parker 1873, Sushkin 1899, Fisher 1944, Jollie 1977, Hertel 1994, Ladygin 1994. No detailed investigation of the skull of sea eagles has been undertaken. MATERIAL AND METHODS Twenty-one skulls of Steller’s Sea Eagle Haliaeetus pelagicus, 12 skulls of White-tailed Sea Eagle H. albicilla and 18 skulls of Bald Eagle H. leucocephalus were examined. Five adult, 4 subadult and 3 eaglet (4 weeks old) skulls were included in the myology study. -
Estimations Relative to Birds of Prey in Captivity in the United States of America
ESTIMATIONS RELATIVE TO BIRDS OF PREY IN CAPTIVITY IN THE UNITED STATES OF AMERICA by Roger Thacker Department of Animal Laboratories The Ohio State University Columbus, Ohio 43210 Introduction. Counts relating to birds of prey in captivity have been accomplished in some European countries; how- ever, to the knowledge of this author no such information is available in the United States of America. The following paper consistsof data related to this subject collected during 1969-1970 from surveys carried out in many different direc- tions within this country. Methods. In an attempt to obtain as clear a picture as pos- sible, counts were divided into specific areas: Research, Zoo- logical, Falconry, and Pet Holders. It became obvious as the project advanced that in some casesthere was overlap from one area to another; an example of this being a falconer working with a bird both for falconry and research purposes. In some instances such as this, the author has used his own judgment in placing birds in specific categories; in other in- stances received information has been used for this purpose. It has also become clear during this project that a count of "pets" is very difficult to obtain. Lack of interest, non-coop- eration, or no available information from animal sales firms makes the task very difficult, as unfortunately, to obtain a clear dispersal picture it is from such sourcesthat informa- tion must be gleaned. However, data related to the importa- tion of birds' of prey as recorded by the Bureau of Sport Fisheries and Wildlife is included, and it is felt some observa- tions can be made from these figures. -

Intelligent animals in captivity have a higher likelihood of participating in selfharm activities compared to their wild counterparts. Feather picking in birds is one such adverse behavior characterized by the individual breaking or removing feathers and, in severe cases, excision of the skin. This behavior increases the susceptibility to sickness and infection. In this study, a feather-picking captive Black Vulture (Coragyps atratus) was observed preening, resting, and displaying self-mutilating behavior. -
Mexican Eagles by Susan Heath Have You Seen a Mexican Eagle? If You Live Along the Texas Coast Chances Are You Have, Even If
Mexican Eagles By Susan Heath Have you seen a Mexican Eagle? If you live along the Texas coast chances are you have, even if you didn’t realize it. “Mexican Eagle” is a colloquial name for the Crested Caracara, which is a common bird along the coast and the south Texas brush country. They are less common in oaks and prairies area of the state, and not present at all in the west or panhandle. Their range is mostly in Mexico and Central America so we are lucky to have them here in Texas. The only other U.S. states with caracaras are Arizona and Florida. Caracaras look like hawks with a sharp bill and talons but they behave more like a vulture by feasting on carrion. In fact, they are actually a tropical falcon as their range implies. Although they are most easily seen eating roadkill with vultures, they will also take live prey. They are quite omnivorous in their diet and will wade in shallow water to catch fish, dig up turtle eggs with their strong feet, or follow farm tractors catching escaping animals. Often they fall back on following vultures to carcasses. They can’t open up a carcass by themselves though and must wait for a vulture or other raptor to do that for them. The Caracara’s body and wings are black but they are easy to recognize with a black cap and orange face set off by a white neck. Their legs are orange too and they are quite a handsome bird if you take the time to notice. -

Crested Caracara in Arizona: Background & Recent Expansion
Arizona Birds - Journal of Arizona Field Ornithologists Volume 2015 CRESTED CARACARA IN ARIZONA: BACKGROUND & RECENT EXPANSION DOUG JENNESS, 4375 E. Rollins Rd., Tucson, AZ 85739, [email protected] ABSTRACT: This paper reviews the research history on the Crested Caracara (Caracara cheriway) in Arizona and summarizes the current knowledge of caracara distribution, which shows that caracaras are expanding in the state. I show that part of this expansion is reflected by new field observations and data documenting nesting northeast of its previously known breeding territory, as well as the extent of nonbreeding caracaras to wander and socially forage in the state. The Crested Caracara (Caracara cheriway; Fig 1), a unique member of the falconidae, is found in the southern United States, parts of Mexico and Central America, northern South America, and Cuba (Ferguson-Lees and Christie 2001). In the United States it breeds in central Florida, the southwestern corner of Louisiana, southern Texas, and southern Arizona (Morrison and Dwyer 2012, Wheeler 2003). Caracaras in Louisiana, Texas, and Arizona are contiguous with breeding populations in Mexico. The Florida population is isolated and has been classified as threatened by state and federal governments since 1987 (Morrison and Dwyer 2012). In 1986, the Arizona Game and Fish Department (AZGFD) contracted Levy to conduct a “status survey” of the Crested Caracara in Arizona with funds from Section 6 of the Endangered Species Act (fide R. Glinski). This three- Figure 1: Adult Crested Caracara at Santa Cruz Flats, year study, conducted on the Tohono O’odham Nation, Pinal Co., Arizona, 29 November 2013.
