The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds.

  • Notes on Some Argentine Anatids
    NOTESON SOME ARGENTINEANATIDS' MILTON W. WELLER ROM mid-August, 1964, until late July, 1965, I was engaged in field work F in Argentina studying waterfowl. Although special emphasis was placed on the Black-headed Duck (Heteronetta atricapilla) , 28 species of anatids were observed in various parts of Argentina. Because so little is known of these species, some general observations are summarized and discussed in the hope that it will point out gaps in our knowledge and encourage additional work on this interesting group. Field work was financed by Grant GB-1067 from the National Science Foundation. Studies of museum specimens in the United States were financed by a Chapman Grant of the American Museum of Natural History, and aided materially in appraising the significance of plumage sequences in Neotropical ducks. AQUATIC HABITATS Although the distribution of Argentine birds was considered by Dabbene (1910) and by Olrog (19591, little comment has been made on the distribution of water types and their influence on waterfowl distribution. Some helpful botanical comments are given by Cabrera (1953) for the Buenos Aires region and, Wetmores’ (1926) observations on both botany and ornithology are excellent. Although time did not permit detailed botanical work during this study, some obvious differences in life-form of marsh vegetation were recorded in the areas visited (Fig. 1) in relation to the species composi- tion of waterbirds. The most extensive zone of freshwater and semipermanent marshes is found in an area roughly bordered by the cities of Venado Tuerto (Santa Fe), Buenos Aires, General Lavalle, Mar de1 Plats and Azul (Buenos Aires).

  • Nesting Biology. Social Patterns and Displays of the Mandarin Duck, a Ix Galericulata
    pi)' NESTING BIOLOGY. SOCIAL PATTERNS AND DISPLAYS OF THE MANDARIN DUCK, A_IX GALERICULATA Richard L. Bruggers A Dissertation Submitted to the Graduate School of Bowling Green State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY December 1974 ' __ U J 591913 W A'W .'X55’ ABSTRACT A study of pinioned, free-ranging Mandarin ducks (Aix galericulata) was conducted from 1971-1974 at a 25-acre estate. The purposes 'were to 1) document breeding biology and behaviors, nesting phenology, and time budgets; 2) describe displays associated with copulatory behavior, pair-formation and maintenance, and social encounters; and 3) determine the female's role in male social display and pair formation. The intensive observations (in excess of 400 h) included several full-day and all-night periods. Display patterns were recorded (partially with movies) arid analyzed. The female's role in social display was examined through a series of male and female introductions into yearling and adult male "display parties." Mandarins formed strong seasonal pair bonds, which re-formed in successive years if both individuals lived. Clutches averaged 9.5 eggs and were begun by yearling females earlier and with less fertility (78%) than adult females (90%). Incubation averaged 28-30 days. Duckling development was rapid and sexual dimorphism evident. 9 Adults and yearlings of both sexes could be separated on the basis of primary feather length; females, on secondary feather pigmentation. Mandarin daily activity patterns consisted of repetitious feeding, preening, and loafing, but the duration and patterns of each activity varied with the social periods.

  • The Ruddy Shelduck in Britain a Review Andrew H
    The Ruddy Shelduck in Britain A review Andrew H. J. Harrop* Dan Powell ABSTRACT The BOU Records Committee has reviewed early British records of Ruddy Shelduck Tadorna ferruginea, including those up to 1892, and post-1950 sightings, in particular those relating to the 1994 influx. None of the pre-1892 records was accepted, but those which occurred in 1892 were considered to justify the species’ retention in Category B of the British List. None of the post-1950 records was accepted.The probability that records of this species relate to individuals of feral or captive origin is very high, yet vagrancy remains possible and is perhaps most likely to involve males in their second calendar-year. * On behalf of the British Ornithologists’ Union Records © British Birds 95 • March 2002 • 123-128 123 The Ruddy Shelduck in Britain he position of any species on the British four weeks between mid July and September List ultimately rests on the unequivocally (Cramp & Simmons 1977).

I have not observed Preening-behind-the- wing, but W. von de Wall (pers. comm.) has observed a male per- form it toward a female. Finally, Wing-flapping appears to be used as a display by males, and it is especially conspicuous because each sequence of it is ended by a rapid stretching of both wings over the back in a posture that makes visible the white axillary feathers, which contrast sharply with the black underwing surface. Copulatory behavior. Precopulatory behavior consists of the male swimming up to the female, his neck stretched and his crest de- pressed, and making occasional Bill-dipping movements. He then suddenly begins to perform more vigorous Head-dipping movements, and the female, if receptive, performs similar Bill-dipping or Head- dipping movements.

The form that occurs in the NACC area is nominate pacificus, so the current species account would remain unchanged except for the distributional statement and notes. Background: The Fork-tailed Swift Apus pacificus was until recently (e.g., Chantler 1999, 2000) considered to consist of four subspecies: pacificus, kanoi, cooki, and leuconyx. Nominate pacificus is highly migratory, breeding from Siberia south to northern China and Japan, and wintering in Australia, Indonesia, and Malaysia. The other subspecies are either residents or short distance migrants: kanoi, which breeds from Taiwan west to SE Tibet and appears to winter as far south as southeast Asia.
