Supplementary Material Tadorna tadorna (Common Shelduck) European Red List of Birds Supplementary Material The European Union (EU27) Red List assessments were based principally on the official data reported by EU Member States to the European Commission under Article 12 of the Birds Directive in 2013-14. For the European Red List assessments, similar data were sourced from BirdLife Partners and other collaborating experts in other European countries and territories. For more information, see BirdLife International (2015).

  • 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).

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.

Had it not been for the almost singlehanded effort of Mr. Peter Scott in organizing and directing this superb collection of birds, it would have required a lifetime of effort, un- limited funds, and constant traveling to obtain the observations I was able to make in a relatively short time.

  • A Molecular Phylogeny of Anseriformes Based on Mitochondrial DNA Analysis
    MOLECULAR PHYLOGENETICS AND EVOLUTION Molecular Phylogenetics and Evolution 23 (2002) 339–356 www.academicpress.com A molecular phylogeny of anseriformes based on mitochondrial DNA analysis Carole Donne-Goussee,a Vincent Laudet,b and Catherine Haanni€ a,* a CNRS UMR 5534, Centre de Genetique Moleculaire et Cellulaire, Universite Claude Bernard Lyon 1, 16 rue Raphael Dubois, Ba^t. Mendel, 69622 Villeurbanne Cedex, France b CNRS UMR 5665, Laboratoire de Biologie Moleculaire et Cellulaire, Ecole Normale Superieure de Lyon, 45 Allee d’Italie, 69364 Lyon Cedex 07, France Received 5 June 2001; received in revised form 4 December 2001 Abstract To study the phylogenetic relationships among Anseriformes, sequences for the complete mitochondrial control region (CR) were determined from 45 waterfowl representing 24 genera, i.e., half of the existing genera. To confirm the results based on CR analysis we also analyzed representative species based on two mitochondrial protein-coding genes, cytochrome b (cytb) and NADH dehydrogenase subunit 2 (ND2). These data allowed us to construct a robust phylogeny of the Anseriformes and to compare it with existing phylogenies based on morphological or molecular data. Chauna and Dendrocygna were identified as early offshoots of the Anseriformes. All the remaining taxa fell into two clades that correspond to the two subfamilies Anatinae and Anserinae. Within Anserinae Branta and Anser cluster together, whereas Coscoroba, Cygnus, and Cereopsis form a relatively weak clade with Cygnus diverging first. Five clades are clearly recognizable among Anatinae: (i) the Anatini with Anas and Lophonetta; (ii) the Aythyini with Aythya and Netta; (iii) the Cairinini with Cairina and Aix; (iv) the Mergini with Mergus, Bucephala, Melanitta, Callonetta, So- materia, and Clangula, and (v) the Tadornini with Tadorna, Chloephaga, and Alopochen.

It extends down to Chilka Lake, Odisha, and has been reported from northern Maharashtra (Rasmussen et al. 2012). Malkhed Reservoir (20º84’33”N, 77º91’89”E), is located in Pohara Malkhed Reserve Forest in Amravati District, Maharashtra, and is 25 km from Amravati city. We visited the reservoir on 09 January 2011 for a casual birding trip. While observing a flock of Ruddy Shelduck T. ferruginea, one differently coloured individual caught our attention. We took a photograph for the record, and carefully resumed observation through binoculars. The bird was about the size of a Ruddy Shelduck, but was coloured white with 197. Common Shelduck Tadorna tadorna in flight at Malkhed Reservoir.

    Tadorna tadorna -- (Linnaeus, 1758) ANIMALIA -- CHORDATA -- AVES -- ANSERIFORMES -- ANATIDAE Common names: Common Shelduck; Shelduck; Tadorne de Belon European Red List Assessment European Red List Status LC -- Least Concern, (IUCN version 3.1) Assessment Information Year published: 2015 Date assessed: 2015-03-31 Assessor(s): BirdLife International Reviewer(s): Symes, A. Compiler(s): Ashpole, J., Burfield, I., Ieronymidou, C., Pople, R., Wheatley, H. & Wright, L. Assessment Rationale European regional assessment: Least Concern (LC) EU27 regional assessment: Least Concern (LC) In Europe this species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 10% in ten years or three generations, or with a specified population structure). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern in Europe. Within the EU27 this species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 10% in ten years or three generations, or with a specified population structure). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern in the EU27.

JOHNSGARD : BEHAVIOURAL ANALYSIS OF ANATIDAl! 71 THE TAXONOMY OF THE ANATIDAE-A BEHAVIOURAL ANALYSIS P. A. JOHNSGARD Received on 14 May 1960 Delacour & Mayr's (1945) classic revision of the Anatidae took waterfowl behaviour into account to a much larger degree than had any previous classifications of the group. However, their utilization of behavi~>ur was primarily at the tribal and generic levels, and no real attempt was made to :use behaviour for det!!rmining intrageneric relationships. Thus far only Lorenz (1941, 1951-1953) has seriously attempteq this with waterfowl, and his analysis of the relatiOnShips within the genus Anas (sensu De1acour & Mayr) has provided a remarkable insight into the evolution of this group.
