Wing; patches of white, which develops after one year of the duck’s life (Dye and Stai, 2004). Plumage (arrangement of feathers) brownish, almost black. Feathers are water proof because of an oil produced by a special gland on its’ tail.

Wetland habitat has declined substantially since European settlement. Although no waterbird species have gone extinct as a result some are now listed as endangered. Reedbeds are taken as an example of how wetlands can be managed. Chapter 2.9 — Freshwater birds: identification, rehabilitation and management• 194 Introduction such as farm dams and ponds.

Phylogeny and Comparative Ecology of Stiff-Tailed Ducks (Anatidae: Oxyurini)
Wilson Bull., 107(2), 1995, pp. 214-234 PHYLOGENY AND COMPARATIVE ECOLOGY OF STIFF-TAILED DUCKS (ANATIDAE: OXYURINI) BRADLEY C. LIVEZEY’ ABSTRACT.-A cladistic analysis of the stiff-tailed ducks (Anatidae: Oxyurini) was con- ducted using 92 morphological characters. The analysis produced one minimum-length, completely dichotomous phylogenetic tree of high consistency (consistency index for infor- mative characters, 0.74). Monophyly of the tribe was supported by 17 unambiguous syna- pomorphies. Within the tribe, Heteronetta (1 species) is the sister-group of other members; within the latter clade (supported by 2 1 unambiguous synapomorphies), Nomonyx (1 species) is the sister-group of Oxyura (6 species) + Biziura (I species). The latter clade is supported by 10 unambiguous synapomorphies. Monophyly of Oxyuru proper is supported by three unambiguous synapomorphies. All branches in the shortest tree except that uniting Oxyuva, exclusive of jumaicensis, were conserved in a majority-rule consensus tree of 1000 boot- strapped replicates. Biziuru and (to a lesser extent) Heteronetta were highly autapomorphic. Modest evolutionary patterns in body mass, reproductive parameters, and sexual dimorphism are evident, with the most marked, correlated changes occurring in Heteronetta and (es- pecially) Biziura. The implications of these evolutionary trends for reproductive ecology and biogeographic patterns are discussed, and a phylogenetic classification of the tribe is presented. Received 27 April 1994, accepted 10 Nov. 1994. The stiff-tailed ducks (Anatidae: Oxyurini) include some of the most distinctive species of waterfowl; among its members are the only obligate nest-parasite (Black-headed Duck; Heteronetta atricapilla) and the spe- cies showing the greatest sexual size dimorphism (Musk Duck; Biziuru lob&z) in the order Anseriformes (Delacour 1959; Johnsgard 1962, 1978; Weller 1968; Livezey 1986). -
A Partial Classification of Waterfowl (Anatidae) Based on Single-Copy Dna
A PARTIAL CLASSIFICATION OF WATERFOWL (ANATIDAE) BASED ON SINGLE-COPY DNA CORT S. MADSEN, KEVIN P. MCHUGH, AND SIWO R. DE KLOET Instituteof MolecularBiophysics, The Florida State University, Tallahassee, Florida 32306 USA ABSTR^CT.--Single-copyDNA-DNA hybridizationwas used to establishphylogenetic re- lationshipsamong 13 speciesof waterfowl (Anatidae) chosenfrom 10 tribes. On the basisof UPGMA clusteringof ATtodistances, we suggestthat the tribes Anatini, Aythyini, Tadornini, Mergini, and Cairinini diverged more recently than the Anserini, Stictonettini,Oxyurini, Dendrocygnini,and Anseranatini.The FreckledDuck (Stictonettanaevosa, tribe Stictonettini) is only distantlyrelated to the other Anatidae.Presumably the lineage divergedvery early. The sheldgeese(tribe Tadornini) and the true geese(Anserini) are only remotely related. The Oxyurini, consideredto be in the subfamilyAnatinae, is remotely related to the other Anatidae. The Dendrocygnini form an isolatedtribe with no closerelationship to the swans and geese(subfamily Anserinae). We found that the screamers(Anhimidae) are distantly related to the Anatidae.

Notes on subfossil Anatidae from New Zealand, including a new species of pink-eared duck Malacorhynchus. Emu 77: 132-135. A new species of pink-eared duck, Malacorhynchus scarletti, is described from subfossil deposits at Pyra- mid Valley, South Island, NZ, and is characterized by larger size. Preliminary observations indicate that subfossil specimens of Biziura from New Zealand are larger and differ qualitatively from B. lobata; for the present, the name Biziura delautouri Forbes, 1892, ought to be retained for the New Zealand form. An erroneous record of Mergus australis is corrected. INTRODUCTION Locality.

Blue-Billed Duck (Oxyura Australis)
Action Statement Flora and Fauna Guarantee Act 1988 No. 174 Blue-billed Duck Oxyura australis Description and Distribution The Blue-billed Duck Oxyura australis, also called Stiff-tail or Diving Duck, is a small, compact duck with a large round head and a short neck (Marchant & Higgins 1990). It is about 40 cm in length and has a weight of about 850 g. Blue-billed Ducks are in the tribe of stiff-tailed ducks whose tail feathers are spiny in appearance and capable of erection (Frith 1977) which includes the Musk Duck Biziura lobata. It is the only member of the genus Oxyura in Australia. This genus is cosmopolitan and contains six species, four of which (including the Blue-billed Duck) are under some threat. There are two populations of the Blue-billed Duck, one in south-east and the other in south-west Blue-billed Duck Oxyura australis Australia. These appear to be isolated from each (Photo: DSE/McCann) other; however, no subspecies are recognised (Blakers et al. 1984, Marchant & Higgins 1990). Male and female Blue-billed Ducks have different plumages. The adult breeding male has a black head with a chestnut to brown body and wings and a distinctive blue bill. Its non-breeding, or eclipse, plumage is similar to that of the adult female. The adult female is medium grey in colour with lighter barring to the head and body feathers, with the breast being lighter in colour. It has a dark bill. Immature birds are generally indistinguishable from the adult female. Species similar in appearance are the Musk Duck, Hardhead Aythya australis and Eurasian Coot Fulica atra. -

EMAIL: [email protected] 3 THIS COPY: PAGE PROOFS ONLY (Figures are low resolution) Odors and Chemical Signaling Julie C. Hagelin 3.1 I NTRODUCTI ON Ornithologists rarely consider the role of chemosensory information in avian reproduction. Yet, every bird that has been examined has a functional olfac- tory system (Bang and W enzel 1985; Roper 1999). L ike other vertebrates, birds detect and respond adaptively to odors in their environment while foraging (e.g. N evitt et al. 1995, 2004; reviewed in Roper 1999), homing over long and short distances (e.g. Bonadonna and Bretagnolle 2002; N evitt and Bonadonna 2005a,b; W allraff 2004, 2005), and perhaps even avoiding predators (Fluck et al. 1996). There is also evidence that some avian species monitor the chemical environment of nests (Petit et al. 2002). H owever, compared to other organisms, information on the production or social use of self-produced odor compounds in birds has been largely neglected (Roper 1999). The chemosensory abilities of birds stand as a promising means of understanding avian biology, because it challenges traditional views that birds respond to their world primarily through visual and auditory signals. L ike other sensory systems, studies of the chemical senses are inherently interdisciplinary, as they involve responses at the molecular, physiological, developmental and behavioral levels. In particular, studies of avian-derived odors have the potential to fundamentally alter how we interpret social behavior. -
