Introduction
INTRODUCTION UC-Stallcup TEXT.indd 1 1/23/14 11:30 AM This contribution to the California Natural History Guide Series of the University of California Press follows a long tradi- tion of books that explain, explore, and celebrate the natural riches of California and beyond. Our intent is to tell beginning birders, or curious naturalists, the how, what, when, where, and why of birding. Because birds are so mobile, some individuals of most spe- cies can wander far from their natal homes and appear any- where. Here we have tried to include only those species most likely to be seen along the coast, from Big Sur to the Oregon border. This is not a field guide to bird identification, but a field guide to the birds themselves. Birding is a word that encompasses many concepts. For some, the activity of searching for and observing birds is a clear window into the natural world, an affirmation of its beauty and its peacefulness. To others, birding is a delightful diversion from the hectic or perhaps boring daily routine of the mod- ern world— providing calm amid the chaos. Birds are nature’s ambassadors, connecting us through their ancient lineage to evolution’s astonishing creativity and offering us some guid- ance, through our study of their habitat needs, in our steward- ship of the Earth. Some people have found the wonders of birds to be the perfect antidote to sadness or loneliness, or a path to comradeship with kindred spirits; others consider the complex- ities of identification or behavior an intellectual challenge. -
Wood Warblers of Lake County (Field Guide)
Wood of Lake County An educational wildlife pamphlet provided by the Lake County Public Resources Department Parks & Trails Division 2 The Lake County Public Resources Department, Parks & Trails Division, manages more than three dozen parks, preserves and boat ramps. Lake County park rangers lead regularly scheduled nature in some of these parks. In partnership with the Lake County hikes, bird and butterfly surveys and other outdoor adventures Water Authority, Parks & Trails also schedules guided paddling adventures. For a listing of Lake County parks and events, call 352-253-4950, email [email protected] or visit Forwww.lakecountyfl.gov/parks. more information about birds that can be seen in Lake County, or bookstores. Information on birds is also available online at the check out a field guide to birds available at many local libraries Cornell Laboratory of Ornithology, www.birds.cornell.edu. Bird watchers in Florida tend to bring a little more on their trips than their Northern peers. While the average temperature in Lake County is a mild 72°F, the summer months in Central Florida can be steamy. Outside enthusiasts are always encouraged to carry sunscreen to protect skin from sunburn, insect repellent to ward off mosquitoes and plenty of water to avoid dehydration. Sunscreen should be 15 SPF or higher and applied 20 minutes before. 3 Park rangers recommend these six popular comprehensive guides: • A Field Guide to the Birds, Eastern and Central North America (Fourth Edition, 1980, Roger Tory Peterson) • Stokes Field Guide to Birds, Eastern Region (First Edition, 1996, Donald and Lillian Stokes) • All the Birds of North America (First Edition, 1997, The American Bird Conservancy) • Field Guide to the Birds of North America (Fourth Edition, 2002, The National Geographic Society) • Focus Guide to the Birds of North America (First Edition, 2000, Kenn Kaufman) • The Sibley Guide to Birds (First Edition, 2000, David Allen Sibley) Insect repellent should contain DEET. -

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. -

Wood Warblers Wildlife Note
hooded warbler 47. Wood Warblers Like jewels strewn through the woods, Pennsylvania’s native warblers appear in early spring, the males arrayed in gleaming colors. Twenty-seven warbler species breed commonly in Pennsylvania, another four are rare breeders, and seven migrate through Penn’s Woods headed for breeding grounds farther north. In central Pennsylvania, the first species begin arriving in late March and early April. Louisiana waterthrush (Parkesia motacilla) and black and white warbler (Mniotilta varia) are among the earliest. The great mass of warblers passes through around mid-May, and then the migration trickles off until it ends in late May by which time the trees have leafed out, making it tough to spot canopy-dwelling species. In southern Pennsylvania, look for the migration to begin and end a few days to a week earlier; in northern Pennsylvania, it is somewhat later. As summer progresses and males stop singing on territory, warblers appear less often, making the onset of fall migration difficult to detect. Some species begin moving south as early as mid and late July. In August the majority specific habitat types and show a preference for specific of warblers start moving south again, with migration characteristics within a breeding habitat. They forage from peaking in September and ending in October, although ground level to the treetops and eat mainly small insects stragglers may still come through into November.

Mercury Contamination in the Common Yellowthroat (Geothlypis
EFFECTS OF MERCURY CONTAMINATION ON INDIVIDUAL QUALITY AND CONDITION OF COMMON YELLOWTHROATS (GEOTHLYPIS TRICHAS) A University Thesis Presented to the Faculty of California State University, East Bay In Partial Fulfillment of the Requirements for the Degree Master of Science in Biology By Deanna de Castro June, 2014 Deanna de Castro © 2014 ii ABSTRACT Historic mines in New Almaden, CA such as the New Almaden Quicksilver Mine (NAQM), are a source of mercury contamination throughout South San Francisco Bay, California. Mines in this area drain into the Coyote Creek (CC) and Guadalupe River (GR). Water quality and sediment assessments for mercury show increasing levels with increasing proximity to the New Almaden. Tellingly, birds captured at upper GR and CC had some of the highest reported concentrations of mercury in the feathers and blood within the United States. Thus, organisms living within the riparian habitats along the CC, GR, and their tributaries may be affected by local environmental mercury. This study investigates of the feather mercury from Common Yellowthroats (Geothlypis trichas) caught at varying distances from NAQM and the relationship between feather mercury and of body condition and individual quality. Birds in upper GR and CC and at Llagas Creek had higher mass, primary wear, and rectrice wear compared to birds in lower CC and GR. Bib size and fluctuating asymmetry of barbule density in rectrices was greater in birds located in CC and GR. Hue of bib feathers was significantly greater in birds caught at lower GR and CC and upper CC. Total mercury concentrations in rectrices were highest in birds caught in upper GR. -

Pre-Lesson Plan
Pre-Lesson Plan Prior to taking part in the Winged Migration program at Tommy Thompson Park it is recommended that you complete the following lessons to familiarize your students with some of the birds they might see and some of the concepts they will learn during their field trip. The lessons can easily be integrated into your Science, Language Arts, Social Studies and Physical Education programs. Part 1: Amazing Birds As a class, read the provided “Wanted” posters. The posters depict a very small sampling of some of the amazing feats and features of birds. To complement these readings, display the following websites so that students can see some of these birds “up close.” Common Loon http://www.schollphoto.com/gallery/thumbnails.php?album=1 Black-Capped Chickadee http://sdakotabirds.com/species_photos/black_capped_chickadee.htm Ruby-Throated Hummingbird http://www.surfbirds.com/cgi-bin/gallery/search2.cgi?species=Ruby- throated%20Hummingbird Downy Woodpecker http://www.pbase.com/billko/downy_woodpecker Great Horned Owl www.owling.com/Great_Horned.htm When you visit Tommy Thompson Park, you may see chickadees, hummingbirds, and woodpeckers. These birds all breed in southern Ontario. However, you probably will not see a Great Horned Owl, because this specific bird is usually flying around at night. Below is a list of some other birds students might see when they visit Tommy Thompson Park. Have them chose one bird each and write a “Wanted” poster for it, focusing on a cool fact about that bird. Some web sites that will help them get started -

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. -
ON VACA KEY, FLORIDA Florida Keys Mosquito Control
Florida Field Naturalist 48(3):102–104, 2020. INTRIGUING PLUMICOLES FROM THE COMMON YELLOWTHROAT (AVES: PASSERIFORMES) ON VACA KEY, FLORIDA LAWRENCE J. HRIBAR Florida Keys Mosquito Control District, 503 107th Street, Marathon, FL 33050 The organisms that live on the outer surface of birds (ectofauna) can be divided into three broad categories: plumicoles inhabit the surface of feathers, dermicoles inhabit the skin, and syringicoles inhabit the inner calamus of feathers (Proctor 2003). Within the past decade, a number of new records of ectofauna from birds have been reported from Vaca Key, Monroe County (Hribar and Miller 2011; Hribar 2013a, 2013b, 2014, 2019). These mainly have been mites and lice, although a fly and a thrips have been reported. In all cases, specimens have been recovered after a dead bird had been washed in a weak detergent solution and the solution had been passed through filter paper to recover specimens (Hribar and Miller 2011). In May of 2020, two Common Yellowthroats (Geothlypis trichas) were found dead outside of a building in the City of Marathon on Vaca Key, Florida (24.729984, −81.039438). Apparent cause of death for both birds was collision with a window. A male was found on 1 May 2020 and a female was found on 3 May 2020 underneath the same window, both apparently having died early in the morning of the day they were found. I handled the specimens and collected ectofauna as previously described (Hribar and Miller 2011). I recovered two species of mites from the birds. Both birds were hosts for large numbers of the feather mite Amerodectes hribari Mironov and Chandler; this mite has also been identified on Common Yellowthroats in Arkansas, Georgia, and Pennsylvania (Mironov and Chandler 2017, Matthews et al. -

Comments on the Peninsular Y Ellowthroat
38 Comments on the Peninsular Y ellowthroat KENN KAUFMAN Although its range is small and its taxonomic fu ture is clouded, this bird still deserves better treatment than it receives in the field guides. Of the several endemic bird taxa harbored by the peninsula of Baja California, Mexico, only three are currently regarded as full species by the Committee on Taxonomy and Nomenclature of the American Ornithologists' Union: the Black fronted or Xantus' Hummingbird Hy locharis xantusii, Gray Thrasher To xostoma cinereum, and Peninsular or Belding's Yellowthroat Geothlypis beldingi. Some of the endemic forms now regarded as subspecies (e.g., "San Lucas" Robin Turdus migratorius confinis, "Baird's" Junco Junco phaeonotus bairdi) are also very distinctive, and well worth the attention of the visiting birder. Hopefully the reader will not immediately lose interest in the Peninsular Yellowthroat when I predict that it is almost certain to join the ranks of the distinctive subspecies here by being "lumped" with the Common Yellowthroat Geothlyp is trichas. My purpose in this note, however, is not to make any taxonomic recommendations (I have not studied the situation in enough depth for that), but rather to clarify a couple of points for the observer who seeks acquaintance with this localized bird. DISTRIBUTION AND HABITATS It is possible that there are two disjunct populations of Peninsular Yellowthroats, one in southern and one in central Baja California. The latter has been designated a distinct subspecies, Geothlypisbe/dingi goldmani, by Oberholser ( 1917). The validity of this second race has been disputed, for reasons to be discussed later.
