Thanks to Erika and Scott Hutchings at CryBaby Design ([email protected]) for their excellent work on this project. It is the Board’s hope that the new site is easier to navigate as well as more esthetically pleasing. The new Colorado Bird Records Committee website (under beta testing at the moment) will be seamlessly integrated into the CFO home site in very short order. The CFO website is full of useful information about our organization as well as birding in Colorado. Is your membership about to expire? Our most recent accomplishment with the site is a new on-line store where you can join CFO or renew your membership directly through the web (http://cfo-link.org/members/join.php). On the same page you can also make contributions to CFO’s newly created Youth Scholarship Fund, our long established Project Fund, or to COBirds (http:// cfo-link.org/birding/COBirds.php), the premiere listserve for the discussion of Colorado birds. Our on-line store makes membership, shopping, and donations easy. We accept all forms of payment, including credit cards. CFO merchandise for sale (http://cfo-link.org/merchandise/index.php) in- cludes hatpins, decals, a great variety of shirts, and Colorado state field checklists. A very recent publication, an annotated checklist, by the Rocky Mountain Bird Observatory, Birds of Barr Lake and Surrounding Areas 1888-1999, by Robert Andrews, Robert Righter, Michael Carter, Tony Leukering, and Alison Banks is also available for purchase and very worthy of a place on your bookshelf. With the holidays approaching, we have added a new line of bird and butterfly note cards. These make great gifts for everyone on your list. Available right now are beautiful cards by Scott Rashid of Estes Park. There are five different designs (hawks, owls, songbirds, hummingbirds, and butterflies) each in a pack of eight cards. And, we will soon be adding cards created by Radeaux and Sherrie York. Remember, 100% of proceeds go to support our organization. Please stop by and visit the new and improved CFO website. And, as always, your comments are welcome. You can contact me at [email protected]. 142 Vol. 38, No. 4 Colorado Birds October 2004 FIELD T RIPS Understanding and Identifying Juncos Ted Floyd December 11, 2004 Join Ted Floyd, editor of Birding and junco enthusiast, for an outing and workshop. The Dark-eyed Junco (Junco hyemalis) is one of the most common birds in North America. It is also one of our most variable and extraordinary of bird species. Here in the Colorado Front Range region, we are at the epicenter of junco diversity. Six highly distinctive races of the Dark-eyed Junco can be observed in a single morning and, in fact, it is possible to view all six in a single flock. Hybrids are frequent (and fascinating), and there are marked differences between the sexes. Yet it is possible to make sense of all of this remarkable diversity. This workshop has been scheduled for the week before the commencement of the 2004-05 Christmas Bird Count season, and thus is perfectly timed for those wishing to make a concerted effort at sorting out the junco races on their Colorado CBCs this year. There is one “assignment” for this workshop prior to attending, please study the photos and discussion at the following website: http://www.oceanwanderers.com/JuncoID.html. Many of the issues that we will confront in the field are nicely addressed at this website. The field trip will be limited to eighteen participants, and is suitable for birders of all levels of expertise. For reservations, please contact Ted at [email protected] or 303-444-6365. E-mail is preferred. The field trip will be from 8:00 A.M.- noon. We will meet at the Mesa Trail parking lot, in southern Boulder County. The parking area is on the north side of SR 170 (the road into Eldorado Canyon State Park), 1.65 miles west of the intersection of SR 170 and SR 93. Note that the parking lot is directly across the street from the familiar Doudy Draw parking lot. Please dress for the weather, and make sure to have your binoculars! 143 Vol. 38, No. 4 Colorado Birds October 2004 CALL FOR N OMINATIONS FOR R ONALD A. RYDER A WARD On February 25, 1995, the CFO Board of Directors passed a resolution establishing the Ronald A. Ryder Award and presenting the first of these awards to Dr. Ryder. The award was presented to Dr. Ryder for distinguished service to the Colorado Field Ornithologists organization and goals, for scholarly contribution to Colorado field ornithology, and for sharing knowledge of Colorado field ornithology with the people of the state. These criteria were established as those which would govern presentation of the award to others in the future. Recipients of the Ronald A. Ryder award are presented a plaque at the annual CFO convention and are granted a life-time membership in the organization. Members of CFO are encouraged to submit nominations for the award. Nominations may be submitted to Tom McConnell, Awards Committee Chair, by U.S. mail or e-mail [email protected], no later than February 1. Nominations should include a full description of the nominee’s contributions to the Colorado Field Ornithologists and to Colorado field ornithology. Tom McConnell Awards Committee Chair 66 Casa Del Monte Ct. Glenwood Springs, CO 81601 CFO WEBSITE We invite you to browse the Colorado Field Ornithologists’ website.

GRAY has been approved for the Department of Biological Sciences and the College of Arts and Sciences by Donald B. Miles Professor of Biological Sciences Florenz Plassmann Dean, College of Arts and Sciences 3 ABSTRACT GRAY, BRANDAN L., Ph.D., August 2019, Biological Sciences Ecology, Morphology, and Behavior in the New World Wood Warblers Director of Dissertation: Donald B. Miles In a rapidly changing world, species are faced with habitat alteration, changing climate and weather patterns, changing community interactions, novel resources, novel dangers, and a host of other natural and anthropogenic challenges. Conservationists endeavor to understand how changing ecology will impact local populations and local communities so efforts and funds can be allocated to those taxa/ecosystems exhibiting the greatest need. Ecological morphological and functional morphological research form the foundation of our understanding of selection-driven morphological evolution. Studies which identify and describe ecomorphological or functional morphological relationships will improve our fundamental understanding of how taxa respond to ecological selective pressures and will improve our ability to identify and conserve those aspects of nature unable to cope with rapid change. The New World wood warblers (family Parulidae) exhibit extensive taxonomic, behavioral, ecological, and morphological variation.

NATURAL HISTORY Taxonomy: Virginia’s Warbler, along with five other wood warbler species in the genus Verminorva, were recently placed in the genus Oreothlypis 1. Virginia’s Warbler is a close relative of Nashville Warbler (O. ruficapilla), but the species have different plumage and breeding habitat requirements 2. Description: Virginia’s Warbler is a small gray warbler with a bold white eye-ring, rufous-crown patch (not always obvious), yellow-green rump, and long tail that almost constantly pumps. It has a variable sized yellow patch on the breast, pale gray belly, and bright yellow undertail coverts. Sexes are similar, but males tend to have more rufous on the crown and more yellow on the breast 3. Similar species in Wyoming include Nashville Warbler, Tennessee Warbler (O. peregrina), and Orange-crowned Warbler (O. celata). However, unlike Virginia’s Warbler, Nashville Warbler has a yellow belly, Tennessee Warbler has white undertail covert’s, and Orange-crowned Warbler has a broken white eye-ring 4. Distribution & Range: Virginia’s Warbler reaches the northern extent of its core North American range in southwestern Wyoming 5, 6.

  • BIRDS of the TRANS-PECOS a Field Checklist
    TEXAS PARKS AND WILDLIFE BIRDS of the TRANS-PECOS a field checklist Black-throated Sparrow by Kelly B. Bryan Birds of the Trans-Pecos: a field checklist the chihuahuan desert Traditionally thought of as a treeless desert wasteland, a land of nothing more than cacti, tumbleweeds, jackrabbits and rattlesnakes – West Texas is far from it. The Chihuahuan Desert region of the state, better known as the Trans-Pecos of Texas (Fig. 1), is arguably the most diverse region in Texas. A variety of habitats ranging from, but not limited to, sanddunes, desert-scrub, arid canyons, oak-juniper woodlands, lush riparian woodlands, plateau grasslands, cienegas (desert springs), pinyon-juniper woodlands, pine-oak woodlands and montane evergreen forests contribute to a diverse and complex avifauna. As much as any other factor, elevation influences and dictates habitat and thus, bird occurrence. Elevations range from the highest point in Texas at 8,749 ft. (Guadalupe Peak) to under 1,000 ft. (below Del Rio). Amazingly, 106 peaks in the region are over 7,000 ft. in elevation; 20 are over 8,000 ft. high. These montane islands contain some of the most unique components of Texas’ avifauna. As a rule, human population in the region is relatively low and habitat quality remains good to excellent; habitat types that have been altered the most in modern times include riparian corridors and cienegas. Figure 1: Coverage area is indicated by the shaded area. This checklist covers all of the area west of the Pecos River and a corridor to the east of the Pecos River that contains areas of Chihuahuan Desert habitat types.

    FRONTISPIECE. Three-striped Warblers (Basileuterus tristriatus) were studied in the northern Andes of Venezuela. Temperate and tropical parulids differ strongly in life histories. Three-striped Warblers have smaller clutches, longer incubation periods, lower nest attentiveness, longer off-bouts, and slower nestling growth rates than most temperate species.

ANDREW COX1,3 AND THOMAS E. MARTIN2 ABSTRACT.—We document reproductive life history traits of the Three-striped Warbler (Basileuterus tristriatus) from 146 nests in Venezuela and compare our results to data from the literature for other tropical and temperate parulid species. Mean (6 SE) clutch size was 1.96 6 0.03 eggs (n 5 96) and fresh egg mass was 2.09 6 0.02 g. The incubation period was 15.8 6 0.2 days (n 5 23) and the nestling period was 10.5 6 0.3 days (n 5 12). Males did not incubate and rarely provided food for females during incubation. Females had 57 6 2% (n 5 49) nest attentiveness (% of time on the nest incubating), which caused egg temperature to commonly become cold relative to development. Both adults fed nestlings and feeding rates increased with nestling age. The growth rate constant for nestlings based on mass was K 5 0.490, which is slower than for north temperate warblers.

  • New Hampshire Wildlife and Habitats at Risk
    CHAPTER TWO New Hampshire Wildlife and Habitats at Risk Abstract All wildlife species native to New Hampshire were eligible for identification as Species of Greatest Conservation Need (SGCN), including game species, non-game species, fish and marine animals. A number of species prioritization lists and expert review processes were used to determine which species should be included as SGCN. A total of 169 species are identified as SGCN in the 2015 Wildlife Action Plan, of which 27 species are listed as state endangered and 14 listed as state threatened. In the 2005 Wildlife Action Plan 118 species were listed as SGCN, and all but 13 of the 2005 SGCN are included in the 2015 revision. The Wildlife Action Plan also identifies 27 distinct habitats that support both common species and species of greatest conservation need. By identifying and protecting high quality examples of all of New Hampshire’s natural communities, all of the state’s native wildlife species will have access to intact habitats. Overview New Hampshire is home to over 500 vertebrate species and thousands of invertebrates. Many of these are common species that thrive in the state’s diverse landscapes and provide enjoyment through wildlife observation, hunting, fishing, and trapping. This chapter describes the process of determining which species are in trouble – declining in numbers, squeezed into smaller patches of habitat, and threatened by a host of issues. These species are designated as Species of Greatest Conservation Need (SGCN). They include not only species on the NH Endangered Species list, but also those that are not yet seriously threatened.
