Systematic Relationships and Biogeography of the Tracheophone Suboscines (Aves: Passeriformes)
MOLECULAR PHYLOGENETICS AND EVOLUTION Molecular Phylogenetics and Evolution 23 (2002) 499–512 www.academicpress.com Systematic relationships and biogeography of the tracheophone suboscines (Aves: Passeriformes) Martin Irestedt,a,b,* Jon Fjeldsaa,c Ulf S. Johansson,a,b and Per G.P. Ericsona a Department of Vertebrate Zoology and Molecular Systematics Laboratory, Swedish Museum of Natural History, P.O. Box 50007, SE-104 05 Stockholm, Sweden b Department of Zoology, University of Stockholm, SE-106 91 Stockholm, Sweden c Zoological Museum, University of Copenhagen, Copenhagen, Denmark Received 29 August 2001; received in revised form 17 January 2002 Abstract Based on their highly specialized ‘‘tracheophone’’ syrinx, the avian families Furnariidae (ovenbirds), Dendrocolaptidae (woodcreepers), Formicariidae (ground antbirds), Thamnophilidae (typical antbirds), Rhinocryptidae (tapaculos), and Conop- ophagidae (gnateaters) have long been recognized to constitute a monophyletic group of suboscine passerines. However, the monophyly of these families have been contested and their interrelationships are poorly understood, and this constrains the pos- sibilities for interpreting adaptive tendencies in this very diverse group. In this study we present a higher-level phylogeny and classification for the tracheophone birds based on phylogenetic analyses of sequence data obtained from 32 ingroup taxa. Both mitochondrial (cytochrome b) and nuclear genes (c-myc, RAG-1, and myoglobin) have been sequenced, and more than 3000 bp were subjected to parsimony and maximum-likelihood analyses. The phylogenetic signals in the mitochondrial and nuclear genes were compared and found to be very similar. The results from the analysis of the combined dataset (all genes, but with transitions at third codon positions in the cytochrome b excluded) partly corroborate previous phylogenetic hypotheses, but several novel arrangements were also suggested. -
American Redstarts
San Antonio Audubon Society May/June 2021 Newsletter American Redstarts By Mike Scully At the time of this writing (early April), the glorious annual spring migration of songbirds through our area is picking up. Every spring I keep a special eye out for one of my favorite migrants, the American Redstart (Setophaga ruticilla). These beautiful warblers flutter actively through the foliage, tail spread, wings drooped, older males clad in black and orange, females and second year males in shades of gray, olive green and yellow. For years, the American Redstart was the only species remaining in the genus Setophaga, until a comprehensive genetic analysis of the Family Parulidae resulted in this genus being grouped with more than 32 species formerly placed in the genus Dendroica and Wilsonia. The name Setophaga was applied to the whole by virtue of seniority. Though now grouped in a large genus, the American Redstart remains an outlier, possessing proportionately large wings, a long tail, and prominent rictal bristles at the base of the relatively wide flat beak, all adaptations to a flycatching mode of foraging. Relatively heavy thigh musculature and long central front toes are apparently adaptations to springing into the air after flying insects. The foraging strategy of redstarts differs from that of typical flycatchers. Redstarts employ a more warbler-like maneuver, actively moving through the foliage, making typically short sallies after flying insect prey, and opportunistically gleaning insects from twigs and leaves while hovering or perched. The wings are frequently drooped and the colorful tail spread wide in order to flush insect prey. -

The awe-inspiring seasonal migrations of birds between breeding and wintering grounds has long attracted the interest of casual naturalists and professional ornithologists alike. Although new technologies improve our ability to follow individual migrants throughout their annual cycle, the scale and detail provided by banding records remain incredibly valuable. The focus of avian migration studies is often the most physiologically challenging migratory feats that sometimes leaves certain species or seasons relatively understudied. The Blackpoll Warbler (Setophaga striata) is well-known for its transoceanic migratory flight during fall migration, the season in which it is best studied, yet the details of its spring migration are not well known, at least not at a continental scale. -
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. -

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. -

Ne:Otropigalmigr:Ant Landbird Monitoring Program for Maineand..New' Brunswick: Assessing Coastal Importance and Management Strategies
NE:OTROPIGALMIGR:ANT LANDBIRD MONITORING PROGRAM FOR MAINEAND..NEW' BRUNSWICK: ASSESSING COASTAL IMPORTANCE AND MANAGEMENT STRATEGIES Norman Famous, Wildlife Ecologist PROJECT SUMMARY Populations of many Neotropical migrant landbirds and shorebirds have shown both long and short-term declines in the Northeastern U.S. and adjacent Canada. The causes of these declines are not entirely understood and vary among species. A cooperative initiative linking Federal and Provincial agencies, private landowners, conservation organizations, industry and field ornithologists was implemented in 1993 to monitor breeding and migratory bird populations in structurally stable boreal forests, pine-spruce woodlands, bogs and fens in the Bay of Fundy ecological zone in Maine and coastal New Brunswick, as well as the Acadian Peninsula in NW New Brunswick. Careful selection of monitoring sites and control of observer expertise are being exercised. Most sites are relatively free from future habitat fragmentation, large changes in habitat structure, human disturbances and insect infestations. The distribution of birds and vegetation characteristics are being mapped within fixed diameter point count circles along 25 new census routes located within 0.5 km of the coast or on larger islands. Birds were censused and mapped along 13 BBS routes in the region. Twenty-two boreal bogs and fens were surveyed. Habitat use by birds and habitat changes over time will be evaluated in addition to long term population trends in both new routes and BBS routes. Breeding season bird use and vegetation change in nine mined peatlands undergoing natural and human-induced restoration are being monitored in Maine and New Brunswick. (Comment, the habitat work was not completed during subsequent years due to insufficient funds.) Seventy-eight fall migration fixed-diameter area-search point count circles were censused every ten days from August through October at six coastal sites. -
Macgillivrays Warbler
Wyoming Species Account MacGillivray’s Warbler Geothlypis tolmiei REGULATORY STATUS USFWS: Migratory Bird USFS R2: No special status USFS R4: No special status Wyoming BLM: No special status State of Wyoming: Protected Bird CONSERVATION RANKS USFWS: No special status WGFD: NSS4 (Bc), Tier II WYNDD: G5, S4 Wyoming Contribution: LOW IUCN: Least Concern PIF Continental Concern Score: 11 STATUS AND RANK COMMENTS MacGillivray’s Warbler (Geothlypis tolmiei) does not have any additional regulatory status or conservation rank considerations beyond those listed above. NATURAL HISTORY Taxonomy: Two subspecies of MacGillivray’s Warbler are recognized and known to breed in the United States: G. t. tolmiei and G. t. monticola 1. In Wyoming, G. t. monticola is the known subspecies; it breeds east of the Pacific slope, in the Rocky Mountains and Great Basin, and winters in higher elevations of central and southern Mexico, occasionally in southern California 2, 3. Two additional subspecies of G. tolmiei are not recognized by the American Ornithologists’ Union (AOU): G. t. intermedia and G. t. austinsmithi. The distinguishing characteristic is reported to be a shorter tail length in G. t. austinsmithi and there are specimens of said subspecies from western Wyoming 1, 4. Recent molecular phylogeny efforts concluded that MacGillivray’s Warbler is more closely related to the genus Geothlypis 5. The AOU approved the genus change in 2011 6. Prior to this, the species was placed in the genus Oporornis. Description: The species is a small wood-warbler in the Parulidae Family. MacGillivray’s Warbler is identifiable in the field during the breeding season. Male upperparts are olive green and underparts are yellow.
