Print Version of the State of the Birds 2009 THE ST A T E OF T HE BIRD S United States of America 2009 Birds are a priceless part of America’s heritage. They are beautiful, they are economically important—and they reflect the health of our environment. This State of the Birds report reveals troubling declines of bird populations during the past 40 years—a warning signal of the failing health of our ecosystems. At the same time, we see heartening evidence that strategic land management and conservation action can reverse declines of birds. This report calls attention to the collective efforts needed to protect nature’s resources for the benefit of people and wildlife. Contents Foreword . 3.

Hawaiian birds and ocean birds appear most at risk, with populations in danger of collapse if immediate conservation measures are not imple- mented. Bird populations in grassland and aridland habitats show the most rapid declines over the past 40 years. Birds that depend on forests are also declining. In contrast, wetland species, wintering coastal birds, and hunted waterfowl show increasing populations during the past 40 years, reflecting a strong focus during this period on wetlands conservation and management.

  • Disaggregation of Bird Families Listed on Cms Appendix Ii
    Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. 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. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1.

  • 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.

We studied the ecology of the endangeredHawaiian Hawk (Buteo solitarius) Downloaded from https://academic.oup.com/condor/article/100/4/654/5126040 by guest on 30 September 2021 on the island of Hawaii for three breeding seasons.Their breeding strategy is a prime example of a K-selected speciescharacteristic of many birds in tropical environments:clutch size was one and brood-rearing was among the longest reported for any diurnal raptor. Twenty-eight nests were found in a variety of native and exotic habitats. Incubation lasted 38 days, nestlingsfledged after 59-63 days, and parentscared for fledglings for an average of 30.2 weeks, which was 2.5 to 10 times longer than similar-size temperate zone raptors. Males assisted females with incubation, but only females brooded young. Radio-tagged juveniles remained within 0.63 km of their nests for the first two months after fledging, after which dispersal distances expanded gradually. Avian (45%) and mammalian (54%) prey dominated the diet of nestlings. There was no evidence that avian malaria, introduced predators, or environmental contaminantswere affecting their population. Based upon es- timates of population size, the availability of suitable nesting habitat, and reproductivesuc- cess, we suggestthe speciesbe consideredfor downlisting from endangeredto threatened status.

Hawks are small to medium-sized diurnal birds of prey, widely distributed around the world and varying greatly in size. This volume contains hawks from the “new world” (the Americas and parts of Oceania). It is a bookend to Volume II of the series, which contains hawks from the “old world” (Eurasia, Africa and Australia). Hawks are divided into two groups; buteonine hawks and accipitrine hawks. The term "true" hawk is sometimes used for the accipitrine hawks. Generally they take birds as their primary prey. The term "buzzard" is preferred for the buteonine hawks.

  • Predators in Flight in This Program, We Explore the Majestic World of Birds of Prey, Including Eagles, Falcons, Vultures, Ospreys, Hawks, and More
    Men’s Programs Predators in Flight In this program, we explore the majestic world of birds of prey, including eagles, falcons, vultures, ospreys, hawks, and more. Birds of prey are also called raptors. Together, we learn more about these fierce, predatory birds from their habits to their habitats, as well as their role in legends, folklore, history, and superstition. Preparation & How-To’s • This is a copy of the complete activity. • Print photos of birds of prey for participants to view or display them on a TV screen. • Print a large-print copy of this discussion activity for participants to follow along and take with them for further study. • Read the article aloud and encourage participants to ask questions. • Use Discussion Starters to encourage conversation about this topic. • Read the Birds of Prey Trivia Q & A and solicit answers from participants. • Check out the Additional Activity for more information about this topic. Predators in Flight Introduction Birds of prey, also known as raptors, include many species of avian predators that rule the skies. Found on every continent on Earth except Antarctica, these powerful birds possess enhanced senses and phenomenal speed. Raptor and human history have been intertwined for centuries, with some birds of prey considered evil or magical, while others are thought of as pests. In contrast, they have also been celebrated as sacred or served as human hunting partners. What Makes a Raptor Most birds of prey are members of the order Accipitriformes, which is made up of 250 species. The birds are divided into diurnal and nocturnal raptors.

  • The Rufous-Faced Crake (Laterallus Xenopterus) and Its Paraguayan Congeners
    THE WILSON BULLETIN A QUARTERLYMAGAZINE OF ORNITHOLOGY Published by the Wilson Ornithological Society VOL. 93, No. 2 JUNE 1981 PAGES 137-300 Wilson Bull., 93(2), 1981, pp. 137-144 THE RUFOUS-FACED CRAKE (LATERALLUS XENOPTERUS) AND ITS PARAGUAYAN CONGENERS ROBERT W. STORER The Black Rail (Laterullus jamaicensis) and other crakes of the genus Luterallus are among the least known American birds, and Ripley (1977:192) points out that “of all the rail family, this group of species collectively is the least studied.” This is not surprising because they are secretive birds living in dense grassy places. But one relatively tame species, the Galapagos Rail (L. spilonotus) has been well studied in the field (Franklin et al. 1979). A second species, the Red-and-White Crake (L. leucopyrrhus) is commonly kept in aviaries where some of its habits have been reported (Meise 1934, Everitt 1962, Levi 1966). Museum spec- imens of Luterullus are few, hence their distribution and status are poorly known; anatomical material is even scarcer. The least known species of the group, the Rufous-faced Crake (L. xen- opterus), was first taken in Paraguay in 1933 and described the following year (Conover 1934). It was not found again until Philip Myers rediscov- ered it in 1976 and Rick Hansen in 1978 (Myers and Hansen 1980). The species has not been illustrated previously, probably because the tail was missing from the type specimen and information on the color of the soft parts was not available. In 1979, I spent 5 weeks in Paraguay with a field party from the Uni- versity of Michigan Museum of Zoology led by Philip Myers, III.
