Those who arrived in daylight had time to explore the phenomenal gardens, despite a rain storm. Day 1 - January 30 Optional day-trip to Carara National Park Guides Vernon and Frank offered an optional day trip to Carara National Park before the tour officially began and all tour participants took advantage of this special opportunity. As such, we are including the sightings from this day trip in the overall tour report. We departed the Hotel at 05:40 for the drive to the National Park. En route we stopped along the road to view a beautiful Turquoise-browed Motmot. -

Olive Warbler (Peucedramus Taeniatus)
Olive Warbler (Peucedramus taeniatus) NMPIF level: Biodiversity Conservation Concern, Level 2 (BC2) NMPIF assessment score: 14 National PIF status: No special status New Mexico BCRs: 34 Primary breeding habitat(s): Mixed Conifer Forest, Ponderosa Pine Forest, primarily above 7,000 feet (both habitats in BCR 34 only) Summary of Concern Olive Warbler is a coniferous forest species of highland Mexico and Central America. At the northern limit of its distribution in southern New Mexico, it requires open stands of mature pine and mixed conifer forest. Associated Species Greater Pewee (BC2), Hutton's Vireo, Mexican Chickadee (BC2), Pygmy Nuthatch (SC2), Western Bluebird (SC2), Yellow-rumped Warbler, Grace's Warbler (SC1), Red-faced Warbler (SC1), Chipping Sparrow, Dark-eyed Junco, Red Crossbill Distribution Olive Warbler is a pine-associated species primarily of highland Central America and Mexico. Its breeding range extends north to east-central Arizona and southwestern New Mexico. Populations in the United States and northern Mexico are at least partially migratory, although winter records exist in New Mexico and Arizona. In New Mexico, Olive Warblers breed across the southern Mogollon Rim and associated isolated mountains, from the Mogollon, Magdalena, and Black ranges south (Lowther and Nocedal 1997, Parmeter et al. 2002). Ecology and Habitat Requirements Olive Warbler occupies both pine forest and pine-oak woodlands in Mexico and Central America. In the southwest, the species occurs mostly in ponderosa pine and mixed conifer forest which contain a component of oak understory. Nests are located high (30-70 feet) in conifers and far from the trunk, in the terminal needles of pine or fir boughs. -

Its use as a meaningful taxonomic indicator has been defunct for well over a century, as the “warblers” encompass hundreds of thin-billed, insectivorous passerines across more than a dozen families worldwide. This is not itself an issue, as many other passerine names (flycatcher, tanager, sparrow, etc.) share this common name “polyphyly”, and conventions or modifiers are widely used to designate and separate families that include multiple groups. -

Powers Introduction Rivoli's Hummingbird was named in honor of the Duke of Rivoli when the species was described by René Lesson in 1829 (1). Even when it became known that William Swainson had written an earlier description of this species in 1827, the common name Rivoli's Hummingbird remained until the early 1980s, when it was changed to Magnificent Hummingbird. In 2017, however, the name was restored to Rivoli's Hummingbird when the American Ornithological Society officially recognized Eugenes fulgens as a distinct species from E. spectabilis, the Talamanca Hummingbird, of the highlands of Costa Rica and western Panama (2).

Production and Survival of the Verdin
PRODUCTION AND SURVIVAL OF THE VERDIN GEORGE T. AUSTIN A review of avian demography (Ricklefs 1973) demonstrates the dearth of knowledge on this subject. Although certain demographic parameters are relatively well known for a wide variety of species, data are generally lacking for their seasonal, annual, and geographic variability. These, including population densities, nesting season, clutch size, and nesting success, are straight forward and can be obtained with relative ease. Survival and annual recruitment are also of interest, but are difficult to determine under field conditions. If first year individuals (I) can be distinguished from adults (A), the ratio of the 2 can be used to calculate annual mortality and recruitment of first year birds into the breeding population given the assumptions of constant population size and no collecting bias. In many species, the first prebasic molt is incomplete (e.g., Dwight 1900)) providing a basis of distinguishing first year birds from adults. Although it has long been recognized that I/A ratios can be used to determine annual survival (Emlen 1940, Snow 1956)) this method has not been widely used. The Verdin (Auriparus fhiceps) is an ideal species for a demographic study as first year birds can be distinguished from adults through at least March (Austin and Rea 1971), the species is nonmigratory and relatively sedentary, and general aspects of its life history are known (Moore 1965, Taylor 1967, 1971, Austin 1976). In this paper, I will analyze the demo- graphic data available for the Verdin from the literature and my own studies in Arizona and Nevada. Geographical and/or seasonal trends will be exam- ined and estimates of mortality and annual recruitment will be presented. -

Ecology, Morphology, and Behavior in the New World Wood Warblers A dissertation presented to the faculty of the College of Arts and Sciences of Ohio University In partial fulfillment of the requirements for the degree Doctor of Philosophy Brandan L. Gray August 2019 © 2019 Brandan L. Gray. All Rights Reserved. 2 This dissertation titled Ecology, Morphology, and Behavior in the New World Wood Warblers by BRANDAN L. 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.
