Not only can we confirm this bird as a juvenile Magnolia Warbler by the tail pattern, but the extent of white in the tail allows us to sex it as a male. Note also the dull grayish-brown edging to the primaries; and, although the mark is not visible in this image, juvenile and older Magnolia Warblers have yellow soles to the feet.

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.

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.

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.

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.

Currently there is concernabout the diminishingnumbers of some North American migrants to the neotropics(Keast and Morton 1980, Rappole et al. 1983, Robbinset al. 1986, Terborgh 1989). To address this problem, numerousauthors call for more detailedobservations of nearcftcmigrants on their wintering grounds(see Hagan and Johnston 1992). Most North American passefinemigrants to the neotropicsare found in forestedhabitats (Rappole et al. 1983), but Leck (1985) in Mexico, Karr (1976) in Panama, and Robinson et al. (1986) in Peru, reportedthat high numbersare alsofound in edge,scrub and secondary habitats.

Established in 1931, the refuge contains about 68,000 acres of salt and brackish marshes, hardwood swamps, pine flatwoods, and pine-oak uplands; parts of which are in Taylor, Jefferson, and Wakulla Counties. An additional 31,700 acres of water in Apalachee Bay are included as part of the refuge through a Presidential Proclamation.
