Bears in Oklahoma
April 2010 Bears in Oklahoma Our speaker for the April 19 meeting of the Oklahoma City Audubon Society will be Jeremy Dixon, wildlife biologist at the Wichita Mountains Wildlife Refuge. His presentation is titled “The Strange But True History of Bears in Oklahoma.” For many years Jeremy was a biologist in Florida where he studied the interactions between black bears and humans. His master’s research was on the Conservation Genetics of the Florida Black Bear. Jeremy moved to Lawton in 2009 to experience life out here in the middle of the continent. Our grass prairie and ancient granite mountains are a new living environment for him. However, the black bears are coming back across Oklahoma from the east presenting birders an experience with a new and large predator to which we are unaccustomed. With an education from Jeremy, hopefully we can learn how to watch the birds while not feeding the bears ourselves. Come out for bear-hugging good time at bird club and bring a friend. County Birding: Kingfisher Jimmy Woodard On March 11, the group of 7 birders entered Kingfisher County in the far southeast corner. We located several small lakes with waterfowl: Canada Geese, Gadwall, Mallard, Green- Winged Teal and Ruddy Duck. We also found an adult Bald Eagle, the first of two found during the trip. Driving the back roads, we observed Great Horned Owl, Phoebe, King- fisher, and a bunch of sparrows – Harris, White Crowned, Song, Savannah, & Lincoln’s. We visited fields along the Cimarron River southeast of Dover. Carla Brueggen & her hus- band lease fields in this area. -

Weight and Size Variation in the Gray Catbird
WEIGHT AND SIZE VARIATION IN THE GRAY CATBIRD BY GILBERT S. RAYNOR INTRODUCTION Weights of wild birds fluctuate becauseof various activity patterns governed by either internal or external stimuli. Important short time- scaleactivities include locomotion,feeding, and defecation;those on a longer time-scaleinclude migration, reproduction, and molt. Stimuli controllingthese activitiesinclude day length, temperature, hunger, fright, and many others, someoperating directly and others indirectly. Weight changesin living birds provide cluesto other aspectsof their biology,to environmentalstresses, and to the longer-periodactivities in which the speciesor individualis engaged. Becauseof the many variablesdetermining the instantaneousweight of a bird and the limited number of times a wild bird can be captured and weighed(particularly without inadvertently influencing the weight), usefulinformation on cyclicalor systematicchanges can best be obtained from statisticalanalyses of large numbersof weightstaken throughout the duration of the cycleof interest.This paper presentsan analysisof weightvariation in the Gray Catbird (Dumetellacarolinensis) and relates thesevariations to time of day and year, activitypatterns, age, and sex. In contrastto weight, linear measurementsof individual birds are relativelyconstant after full growth is attained.Some change takes place in wing and tail length by wear betweenmolts but this is typicallyslow and gradual (Blake, 1971). Thus, sizeof the Catbird is documentedby age and sex but related only to season. Many authorshave reported bird weightsand several(Baldwin and Kendeigh, 1938; Becker and Stack, 1944; Wiseman, 1975) have ana- lyzedtheir data by age, sex,time of day or season.Most data were taken from living birds but somefrom tower kills (Graber and Graber, 1962; Tordoff and Mengel, 1956). Causesof weight changesand their signif- icance have been discussedpreviously (Nice, 1938; Blake, 1956). -

Accepted: October 7, 2015 Data deposition: This project has been deposited at GenBank under the accession numbers KC545397-KC545409, KT894672. Abstract Passerines are the largest avian order, and the 6,000 species comprise more than half of all extant bird species. This successful radiation probably had its origin in the Australasian region, but dating this origin has been difficult due to a scarce fossil record and poor biogeographic assumptions. Many of New Zealand’s endemic passerines fall within the deeper branches of the passerine radiation, and a well resolved phylogeny for the modern New Zealand element in the deeper branches of the oscine lineage will help us understand both oscine and passerine biogeography. To this end we present complete mitochondrial genomes representing all families of New Zealand passerines in a phylogenetic framework of over 100 passerine species. -
Songbird Use of Native and Invasive Fruit in the Northeastern USA
Wildlife Society Bulletin 44(3):570–578; 2020; DOI: 10.1002/wsb.1113 Original Article Songbird Use of Native and Invasive Fruit in the Northeastern USA MICHELLE A. LABBÉ, Department of Environmental Conservation, University of Massachusetts, Amherst, MA 01003, USA DAVID I. KING,1 U.S. Department of Agriculture Forest Service Northern Research Station, University of Massachusetts, Amherst, MA 01003, USA ABSTRACT Fruit is consumed by songbirds, yet whether or not it comprises an important component of habitat quality depends on the extent to which it is used by birds. In addition, there is evidence fruits of exotic invasive species may be nutritionally inferior to fruits of native species, so the influence of plant invasion on bird body condition is of interest to managers. Birds that consume invasive fruits may also serve as seed vectors, and consumption of fruits of invasive species may exacerbate invasion. Thus, the extent to which songbirds consume fruits of native versus invasive plant species, influence of plant invasion on bird body condition, and extent to which birds exhibit foraging behaviors that elevate their potential to act as dispersers of invasive species have important implications for habitat management. To understand bird use of native and invasive fruits and the potential role of birds in dispersing invasive plants, we observed bird foraging, measured body condition indices of birds captured in mist nets, measured available fruits of native and invasive plants, and calculated indices of seed dispersal for bird species based on fruit handling and consumption, within 16 shrubland sites in western Massachusetts, USA. Our findings indicate that birds use fruit extensively (57% of foraging events), use varied among species, and frugivorous species at our sites generally chose the fruit of native species, especially Prunus, over fruits of invasive species. -
Bird-Friendly Building Guide
Bird-Friendly Building Design Vassar’s Bridge for Laboratory Sciences, shown here under construction in October 2015. The building is scheduled to open in January 2016. Cover rendering and photos courtesy of Ennead Architects Cover rendering and photo this page: The new Bridge for Laboratory Sciences building at Vassar College, designed by Richard Olcott/Ennead Architects, redefines the identity of the sciences on the College’s historic campus and provides technologically advanced facilities for students, faculty, and researchers. Fundamental to the building’s design is its seamless integration with the natural landscape, scale, and campus aesthetic of the College. In this natural wooded setting, the need for strategies to reduce bird collisions with the building was apparent. In response, the building was designed to comply with LEED Pilot Credit 55: Bird Collision Deterrence. Ennead managing partner Guy Maxwell is a nationally recognized champion of bird-friendly design and has led Ennead’s innovative approach to make the building’s glazing safer for birds, employing patterned glass, screens and sunshades, and Ornilux glass, a specialty glass product that uses a UV coating visible to birds but not humans. By framing and showcasing views of the landscape, the building celebrates and connects students with the surrounding environment, while the overall development of the precinct repurposes an Exterior glass detail Glass detail, showing frit pattern underutilized sector of campus.

The Division of the Major Songbird Radiation Into Passerida and 'Core
TheBlackwell Publishing Ltd division of the major songbird radiation into Passerida and ‘core Corvoidea’ (Aves: Passeriformes) — the species tree vs. gene trees MARTIN IRESTEDT & JAN I. OHLSON Submitted: 19 July 2007 Irestedt, M. & Ohlson, J. I. (2008). The division of the major songbird radiation into Passerida Accepted: 26 November 2007 and ‘core Corvoidea’ (Aves: Passeriformes) — the species tree vs. gene trees. — Zoologica doi:10.1111/j.1463-6409.2007.00321.x Scripta, 37, 305–313. The knowledge of evolutionary relationships among oscine songbirds has been largely improved in recent years by molecular phylogenetic studies. However, current knowledge is still largely based on sequence data from a limited number of loci. In this study, we re-evaluate relationships among basal lineages within the ‘core Corvoidea’ and Passerida radiations, by adding additional loci to previously published data. The trees obtained from the individual genes suggest incongruent topologies. Especially the positions of Callaeatidae (wattlebirds), Cnemophilidae (satinbirds) and Melanocharitidae (longbills and berrypeckers) vary among the trees, but RAG-1 is the only gene that unambiguously suggested a ‘core Corvoidea’ affinity for these taxa. Analyses of various combined data sets show that the phylogenetic positions for Callaeatidae, Cnemophilidae and Melanocharitidae largely depend on which genes that have been combined. As the RAG-1 gene has contributed to a majority of the phylogenetic information in previous studies, it has deeply influenced previous molecular affinities of these taxa. Based on the current data, we found a reasonable support for a Passerida affinity of Callaeatidae and Cnemophilidae, contrary to previous molecular studies. The position of Melanocharitidae is more unstable but a basal position among Passerida is congruent with a deletion observed in the glyceraldehyde-3-phosphodehydrogenase (GAPDH) loci. -
2019 Waterfowl Population Status Survey
U.S. Fish & Wildlife Service Waterfowl Population Status, 2019 Waterfowl Population Status, 2019 August 19, 2019 In the United States the process of establishing hunting regulations for waterfowl is conducted annually. This process involves a number of scheduled meetings in which information regarding the status of waterfowl is presented to individuals within the agencies responsible for setting hunting regulations. In addition, the proposed regulations are published in the Federal Register to allow public comment. This report includes the most current breeding population and production information available for waterfowl in North America and is a result of cooperative eforts by the U.S. Fish and Wildlife Service (USFWS), the Canadian Wildlife Service (CWS), various state and provincial conservation agencies, and private conservation organizations. In addition to providing current information on the status of populations, this report is intended to aid the development of waterfowl harvest regulations in the United States for the 2020–2021 hunting season. i Acknowledgments Waterfowl Population and Habitat Information: The information contained in this report is the result of the eforts of numerous individuals and organizations. Principal contributors include the Canadian Wildlife Service, U.S. Fish and Wildlife Service, state wildlife conservation agencies, provincial conservation agencies from Canada, and Direcci´on General de Conservaci´on Ecol´ogica de los Recursos Naturales, Mexico.

Loss of breeding and Recovery Plan Status: Not Applicable wintering habitat, as well as harvest for the millinery trade, Geographic Coverage: South Florida led to a severe decline of this species. Bachmans warbler was the seventh most common migrant along the lower Suwannee River in earlier times. The last sighting of Bachmans warbler in Florida was reported in 1977. The last confirmed sighting anywhere in the U.S. was in 1988. Description Bachmans warbler is one of the smallest warblers with a total length of 10 to 11 cm. The bill is slender with a slight- ly downward curve. The male is olive-green above with yellow forehead, lores, eye-ring, chin, and underparts, a black throat and crown, and dusky wings and tail. Males also have a yellow shoulder patch and bright rump. The female lacks any black coloration and has olive green upperparts with yellow forehead and underparts. The eye- ring is whiter than in the males, and the crown is grayish. Immature males resemble females. Males are not difficult to distinguish from other warblers, however, the drab col- oration of the females and immatures makes positive iden- tification difficult (Hamel and Gauthreaux 1982, World Wildlife Fund 1990, Curson et al. 1994, Stevenson and Anderson 1994, Hamel 1995, Anderson 1996). -

They are mostly nocturnal and live underground in burrows. At around the size of a domestic chicken, kiwi are by far the smallest living ratites (which also consist of ostriches, emus, rheas, and cassowaries). For their relative body size, they lay the largest egg of any species of bird in the world. There are five recognized species, with several subspecies and variants. All species of Kiwi are included in this Songbird ReMix volume. The model is full featured with layered fur-like feathers, easy-to-use controls for posing and even full use of its tiny wings (which can be revealed from under the layered fur). Overview The set is located within the Animals : Songbird ReMix folder. Here is where you will find a number of folders, such as Bird Library, Manuals and Resources . Let's look at what is contained in these folders: o Bird Library: This folder holds the actual species and poses for the "premade" birds.
