BIRD POPULATIONS (ISSN 1074-1755) is an entirely electronic journal published annually by The Institute for Bird Populations. Copyright 2007 by The Institute for Bird Populations. BIRD POPULATIONS can be accessed free of charge at www.birdpop.org. All material in this journal may be copied for the non-commercial purpose of educational or scientific advancement without the need to seek specific permission Bird Populations is an annual journal of dynamic global avian demography and biogeography that publishes original research and review papers dealing with changes in the numbers, distributions, and ecological relationships of birds. Papers providing documentation of quantitative changes in bird populations or distributions are preferred, but papers providing baseline population or distribution information are also acceptable. Papers describing or evaluating field techniques or analytical methods for assessing population and distribution changes are also welcome. Contributions are encouraged from throughout the world from both well-known and little-studied avifaunas. Bird Populations is published in English with abstracts in Spanish, French, and German. Authors should submit three complete double-spaced copies of each manuscript, in English, to: David G. Ainley, Editor, Bird Populations, H.T. Harvey and Associates, 983 University Avenue, Bldg D, Los Gatos, CA 95032; [email protected]. Guidelines for preparing and submitting papers to Bird Populations, including the format for literature citations, are similar to those of The Condor and Studies in Avian Biology. Authors are urged to examine a recent issue of Bird Populations and follow the niceties of the journal’s style. All research papers and review articles submitted to Bird Populations are subject to peer review. Submission of accepted papers on computer-readable magnetic media (MS-Word, or WordPerfect files in MS-DOS or Macintosh format) is encouraged strongly and will be appreciated greatly. Bird Populations also prints or reprints annual reports of major avian monitoring programs from around the world. These annual reports are an important focus of the journal which is intended to serve as a yearbook on the status of the Earth’s birdlife by bringing together, under a single cover, information from many widespread localities on the annual changes in the abundance and distribution of birds. We believe that the printing or reprinting of these annual reports will draw attention, in a timely manner, to short-term population fluctuations that may turn out to be geographically widespread or that may signal the beginnings of longer-term trends. We hope that the publication of these reports will provide ornithologists with a global informational network for addressing avian population changes, will encourage an integrative global approach to avian monitoring studies, will stimulate the establishment of additional avian monitoring programs, particularly in the developing nations, and ultimately will aid in the conservation of global avian diversity. Any agency or organization from anywhere in the world conducting a long-term, relatively large-scale, standardized, avian monitoring program is invited to submit the annual (or biennial) report of that program to Bird Populations for printing or reprinting. Annual reports submitted for original printing will undergo peer review; please submit three copies of such reports. Already published annual reports submitted for reprinting will not be peer reviewed, but will be screened by the Editor when first submitted with regard to the scope and scientific merit of the monitoring program and the appropriateness of the methods and analyses; please submit one copy of such reports. Annual reports of programs included for publication will be printed or reprinted without page charges. Submission of reports on computer-readable magnetic media is encouraged and will be appreciated.

    TheCondor97:174-196 0 The Cooper Ornithological Society 1995 PHYLOGENETIC REANALYSIS OF STRAUCH’S OSTEOLOGICAL DATA SET FOR THE CHARADRIIFORMES PHILIP c. CHU Department of Biology and Museum of Zoology The University of Michigan, Ann Arbor, MI 48109 Abstract. Strauch’s (1978) compatibility analysisof relationshipsamong the shorebirds (Charadriifonnes) was the first study to examine the full range of charadriifonn taxa in a reproducibleway. SubsequentlyMickevich and Parenti (1980) leveled seriouscharges against Strauch’s characters,method of phylogenetic inference, and results. To account for these charges,Strauch ’s characterswere re-examined and recoded, and parsimony analyseswere performed on the revised matrix. A parsimony analysison 74 taxa from the revised matrix yielded 855 shortesttrees, each length = 286 and consistencyindex = 0.385. In each shortest tree there were two major lineages,a lineageof sandpiper-likebirds and a lineageof plover- like birds; the two formed a monophyletic group, with the auks (Alcidae) being that group’s sister taxon. The shortest trees were then compared with other estimates of shorebird re- lationships, comparison suggestingthat the chargesagainst Strauch’s results may have re- sulted from the Mickevich and Parenti decisions to exclude much of Strauch’s character evidence. Key words: Charadrilformes; phylogeny; compatibility analysis: parsimony analysis; tax- onomic congruence.

  • Waterbirds of Namdapha Tiger Reserve, Arunachal Pradesh with Special Reference to White-Bellied Heron Ardea Insignis
    Rec. zool. Surv. India: l08(Part-3) : 109-118, 2008 WATERBIRDS OF NAMDAPHA TIGER RESERVE, ARUNACHAL PRADESH WITH SPECIAL REFERENCE TO WHITE-BELLIED HERON ARDEA INSIGNIS GOPINATHAN MAHESW ARAN* Zoological Survey of India, M-Block, New Alipore, Kolkata-700 053, India INTRODUCTION Namdapha Tiger Reserve has a rich aquatic bird fauna, mostly because of many freshwater lakes/ponds located at higher altitudes as well as within the evergreen forest patches and the complex river system it has. While surveys were carried out by the research team of the Zoological Survey of India (Ghosh, 1987) from March 1981 to March 1987, the following prominent waterbirds were recorded from Namdapha : Goliath Heron Ardea goliath, Large Egret Casmerodius albus, Chinese Pond Heron Ardeola bacchus, Little Egret Egretta garzetta, Common Merganser Mergus Inerganser, Eastern Marsh Harrier Circus spilonotus, and at least seven species of kingfishers, beside the migrant Common Teal Anas crecca. However, the team did not record any White-bellied Heron. Interestingly, I did not record Goliath Heron during my surveys in two years, which the team did so. The White-bellied Heron Ardea insignis (Family : Ardeidae) is a little known species occurring in swamps, marshes and forests from Nepal through Sikkim, Bhutan and northeast Assam in India to Bangladesh, Arakan and north Bunna (Walters 1976). According to Ali and Ripley (1987), it is a highly endangered species and restricted to undisturbed reed ~eds and marshes in eastern Nepal and the Sikkim terai, Bihar (north of the Ganges river), Bhutan duars to northern Assam, Bangladesh, Arakan and north Burma (= Myanmar). In Assam, it has been reported from Kaziranga National Park (Barua and Sharma 1999), Jamjing and Bordoloni of Dhemaji district (Choudhury 1990, 1992, 1994), Dibru-Saikhowa Wildlife Sanctuary and Biosphere Reserve (Choudhury 1994), Pobitara Wildlife Sanctuary (Choudhury 1996a, Baruah et al.

Recording more than 22,000 waterbirds on a 140 km river stretch though as in 2019 is almost unheard of and unique in the world. The middle reaches of the Ayeyarwady River between Myitkyina and Bagan hosted in 2019 more than 40,000 waterbirds, more than half of these were recorded on the river between Sagaing and Bagan only, qualifying this river stretch for Ramsar under criterion 5! Yet these numbers are only a small fraction of what used to winter regularly on the river only 20 years ago. Fortunately we have the accounts of J. van der Ven, Simba Chan and others who surveyed the river almost 20 years ago and recorded more than double those numbers and many more species that sadly have not been seen over the past three years. Spot-billed Pelicans, Black-necked Storks and Cotton Pygmy Goose all have dis- appeared and several other species like the River Tern and Black-bellied Tern are on the brink of local extinction. The latter globally endangered species might not just disappear from the Ayeyarwady River but from the entire planet if no conservation action is taken.
