Widely Distributed Breeding Populations of Canada Warbler (Cardellina Canadensis) Converge on Migration Through Central America A
Roberto-Charron et al. BMC Zoology (2020) 5:10 https://doi.org/10.1186/s40850-020-00056-4 BMC Zoology RESEARCH ARTICLE Open Access Widely distributed breeding populations of Canada warbler (Cardellina canadensis) converge on migration through Central America A. Roberto-Charron1* , J. Kennedy2, L. Reitsma3, J. A. Tremblay4,5, R. Krikun6, K. A. Hobson7, J. Ibarzabal5 and K. C. Fraser1 Abstract Background: To effectively conserve migratory species, the entire range encompassed by their annual life cycle needs to be considered. Most research on Nearctic-Neotropical migratory birds has focused on the breeding grounds resulting in a general lack of knowledge regarding the wintering and migratory periods. The Canada Warbler (Cardellina canadensis) has declined by 71% from 1970 to 2012, at a rate of 2.9% per year, and is listed as Threatened in Canada. As with most Nearctic-Neotropical migrants, conservation efforts outside the breeding range are limited by a poor understanding of migration routes and the connectivity between specific breeding and wintering populations. Results: To determine migratory routes of multiple breeding populations of Canada Warblers, we directly-tracked individuals using light-level geolocators deployed at four sites across the breeding range, spanning approximately 43 degrees in longitude (Alberta, Manitoba and Québec, Canada, and New Hampshire, USA). Twenty-five geolocators with usable data were recovered from three sites and were analyzed using FlightR to determine fall migration routes (n = 18) and individual wintering sites (n = 25). Individuals from all breeding populations took a western fall migration route at the Gulf of Mexico; with 77.8% of birds funnelling into a narrow geographic space along the western side of the Gulf of Mexico (97°W-99°W). -
Red-Breasted Nuthatch and Golden-Crowned Kinglet
Red-breasted Nuthatch and Golden-crowned Kinglet: The First Nests for South Carolina and Other Chattooga Records Frank Renfrow 611 South O’Fallon Avenue, Bellevue, KY 41073 [email protected] Introduction The Chattooga Recreation Area (referred to as CRA for purposes of this article), located adjacent to the Walhalla National Fish Hatchery (780 m) within Sumter National Forest, Oconee Co., South Carolina, has long been noted as a unique natural area within the state. The picnic area in particular, situated along the East Fork of the Chattooga River, contains an old-growth stand of White Pine (Pinus strobus) and Canada Hemlock (Tsuga canadensis) with state records for both species as well as an impressive understory of Mountain Laurel (Kalmia latifolia) and Great Laurel (Rhododendron maximum) (Gaddy 2000). Nesting birds at CRA not found outside of the northwestern corner of the state include Black-throated Blue Warbler (Dendroica caerulescens) and Dark-eyed Junco (Junco hyemalis). Breeding evidence of two other species of northern affinities, Red-breasted Nuthatch (Sitta canadensis) and Golden-crowned Kinglet (Regulus satrapa) has previously been documented at this location (Post and Gauthreaux 1989, Oberle and Forsythe 1995). However, nest records of these two species have not been documented prior to this study. The summer occurrence of two other northern species on the South Carolina side of the Chattooga River, Brown Creeper (Certhia americana) and Winter Wren (Troglodytes troglodytes) has not been previously recorded. Only a few summer records of the Blackburnian Warbler (Dendroica fusca) have been noted for the state. Extensive field observations were made by the author in the Chattooga River area of Georgia and South Carolina during the breeding seasons of 2000, 2002 and 2003 in order to verify breeding of bird species of northern affinities. -

Disaggregation of Bird Families Listed on Cms Appendix Ii
Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1.

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. -

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. -
Thick-Billed Warbler (Iduna Aedon) at Gambell, Alaska: First Record for North America Gary H

LEHMAN, 11192 Portobelo Dr., San Diego, California 92124; [email protected] AARON J. LANG, 40208 Alpenglow Circle, Homer, Alaska 99603; [email protected] VICTOR AND RUBEN STOLL, 899 Miller Rd., Centerville, Tennessee 37033; [email protected] In the evening on 8 September 2017, in the “far boneyard” at Gambell, St. Law- rence Island, Alaska (63.78° N, 171.74° W), Victor and Ruben Stoll flushed a pas- serine they could not immediately identify. The “boneyards” are large pits excavated by the resident Yupik Natives seeking buried ivory and artifacts, a result of several thousand years of sea-mammal hunting from this island’s Northwest Cape. Working these pits turns the soil, which has resulted in the growth of relatively lush vegetation consisting of two species of Artemisia, known locally as “wormwood.” The combina- tion of lush vegetation (reaching 0.5–1 m in height) and deep depressions that offer protection from the wind is attractive to migrant and vagrant landbirds in the otherwise flat, gravelly landscape. Soon thereafter, we, along with Greg Scyphers, Monte Taylor, and other birders then at Gambell, converged at the far boneyard in search of the bird. It was soon relocated and seen on the ground briefly by Lang, who suggested it was a Thick-billed Warbler (Iduna aedon), a bird he was familiar with from southeastern Asia and a species not previously recorded in Alaska or North America. -
