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.

Simple Summary: Cages preventing access to birds were used to measure the rate of predation by birds in a spruce budworm population during the decline of an outbreak. Three species of budworm-feeding warblers were involved in this predation on larvae and pupae. It was found that bird predation is a very important source of mortality in declining spruce budworm populations, and that bird foraging behavior changes as budworm prey become rare at the end of the outbreak. Abstract: The impact of avian predation on a declining population of the spruce budworm, Cho- ristoneura fumifereana (Clem.), was measured using single-tree exclosure cages in a mature stand of balsam fir, Abies balsamea (L.), and white spruce, Picea glauca (Moench.)

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.
