    his is the 20th published report of the ABA Checklist Committee (hereafter, TCLC), covering the period July 2008– July 2009. There were no changes to commit - tee membership since our previous report (Pranty et al. 2008). Kevin Zimmer has been elected to serve his second term (to expire at the end of 2012), and Bill Pranty has been reelected to serve as Chair for a fourth year. During the preceding 13 months, the CLC final - ized votes on five species. Four species were accepted and added to the ABA Checklist , while one species was removed. The number of accepted species on the ABA Checklist is increased to 960. In January 2009, the seventh edition of the ABA Checklist (Pranty et al. 2009) was published. Each species is numbered from 1 (Black-bellied Whistling-Duck) to 957 (Eurasian Tree Sparrow); ancillary numbers will be inserted for all new species, and these numbers will be included in our annual reports. Production of the seventh edi - tion of the ABA Checklist occupied much of Pranty’s and Dunn’s time during the period, and this com - mitment helps to explain the relative paucity of votes during 2008–2009 compared to our other recent an - nual reports.

U.S. Fish and Wildlife Service officials are pleased to announce that the world’s oldest known banded bird in the wild, a Laysan albatross named Wisdom, was sighted on November 19 on Midway Atoll National Wildlife Refuge within Papahānaumokuākea Marine National Monument. Just in time for the special day of giving thanks, Wisdom was spotted with her mate amongst the world’s largest nesting albatross colony. “In the face of dramatic seabird population decreases worldwide –70% drop since the 1950’s when Wisdom was first banded–Wisdom has become a symbol of hope and inspiration,” said Refuge Manager, Dan Clark.” We are a part of the fate of Wisdom and it is gratifying to see her return because of the decades of hard work conducted to manage and protect albatross nesting habitat.” “Wisdom left soon after mating but we expect her back any day now to lay her egg,” noted Deputy Refuge Manager, Bret Wolfe. “It is very humbling to think that she has been visiting Midway for at least 64 years. Navy sailors and their families likely walked by her not knowing she could possibly be rearing a chick over 50 years later.

  • Birds on San Clemente Island, As Part of Our Work Toward the Recovery of the Island’S Endangered Species
    WESTERN BIRDS Volume 36, Number 3, 2005 THE BIRDS OF SAN CLEMENTE ISLAND BRIAN L. SULLIVAN, PRBO Conservation Science, 4990 Shoreline Hwy., Stinson Beach, California 94970-9701 (current address: Cornell Laboratory of Ornithology, 159 Sapsucker Woods Rd., Ithaca, New York 14850) ERIC L. KERSHNER, Institute for Wildlife Studies, 2515 Camino del Rio South, Suite 334, San Diego, California 92108 With contributing authors JONATHAN J. DUNN, ROBB S. A. KALER, SUELLEN LYNN, NICOLE M. MUNKWITZ, and JONATHAN H. PLISSNER ABSTRACT: From 1992 to 2004, we observed birds on San Clemente Island, as part of our work toward the recovery of the island’s endangered species. We increased the island’s bird list to 317 species, by recording many additional vagrants and seabirds. The list includes 20 regular extant breeding species, 6 species extirpated as breeders, 5 nonnative introduced species, and 9 sporadic or newly colonizing breeding species. For decades San Clemente Island had been ravaged by overgrazing, especially by goats, which were removed completely in 1993. Since then, the island’s vegetation has begun recovering, and the island’s avifauna will likely change again as a result. We document here the status of that avifauna during this transitional period of re- growth, between the island’s being largely denuded of vegetation and a more natural state. It is still too early to evaluate the effects of the vegetation’s still partial recovery on birds, but the beginnings of recovery may have enabled the recent colonization of small numbers of Grasshopper Sparrows and Lazuli Buntings. Sponsored by the U. S. Navy, efforts to restore the island’s endangered species continue—among birds these are the Loggerhead Shrike and Sage Sparrow.

We recover and analyze mitochondrial Anatidae genomes of C. lawi and five additional Mergini species, including the extinct Labrador Duck, Camptorhynchus Ancient DNA labradorius. Despite its diving morphology, C. lawi is reconstructed as an ancient relictual lineage basal to the Labrador duck dabbling ducks (tribe Anatini), revealing an additional example of convergent evolution of characters related to Mitochondrial genome feeding behavior among ducks. The Labrador Duck is sister to Steller’s Eider which may provide insights into the California paleontology Duck evolution evolution and ecology of this poorly known extinct species. Our results demonstrate that inclusion of full length mitogenomes, from taxonomically distributed ancient and modern sources can improve phylogeny reconstruc- tion of groups previously assessed with shorter single-gene mitochondrial sequences. 1.

  • Common Birds of the Estero Bay Area
    Common Birds of the Estero Bay Area Jeremy Beaulieu Lisa Andreano Michael Walgren Introduction The following is a guide to the common birds of the Estero Bay Area. Brief descriptions are provided as well as active months and status listings. Photos are primarily courtesy of Greg Smith. Species are arranged by family according to the Sibley Guide to Birds (2000). Gaviidae Red-throated Loon Gavia stellata Occurrence: Common Active Months: November-April Federal Status: None State/Audubon Status: None Description: A small loon seldom seen far from salt water. In the non-breeding season they have a grey face and red throat. They have a long slender dark bill and white speckling on their dark back. Information: These birds are winter residents to the Central Coast. Wintering Red- throated Loons can gather in large numbers in Morro Bay if food is abundant. They are common on salt water of all depths but frequently forage in shallow bays and estuaries rather than far out at sea. Because their legs are located so far back, loons have difficulty walking on land and are rarely found far from water. Most loons must paddle furiously across the surface of the water before becoming airborne, but these small loons can practically spring directly into the air from land, a useful ability on its artic tundra breeding grounds. Pacific Loon Gavia pacifica Occurrence: Common Active Months: November-April Federal Status: None State/Audubon Status: None Description: The Pacific Loon has a shorter neck than the Red-throated Loon. The bill is very straight and the head is very smoothly rounded.

  • Habitat Use of Wintering Bird Communities in Sonora, Mexico: the Importance of Riparian Habitats
    Studies in Avian Biology No. 37:53–68 HABITAT USE OF WINTERING BIRD COMMUNITIES IN SONORA, MEXICO: THE IMPORTANCE OF RIPARIAN HABITATS JOSÉ FERNANDO VILLASEÑOR-GÓMEZ Abstract. Riparian systems are dynamic and diverse despite their limited areal extent. They are espe- cially important for breeding bird communities in southwestern US and are highly used as migra- tory corridors; however, their importance for wintering birds has not been assessed systematically. Information from 1,816 standard 10-min point counts was gathered at 85 locations in the State of Sonora, Mexico from sea level to 2,175 m during January and February 2004–2006. I detected 253 bird species across 14 vegetation types, including nine categories of riparian vegetation. Eighty percent of total species were detected in riparian habitats, and 72% were detected in non-riparian habitats. The mean number of species and individuals detected per count were signifi cantly higher in ripar- ian habitats than in non-riparian habitats for migratory species, but not for residents. A hierarchical classifi cation analysis showed that riparian bird communities are different from those in non-riparian communities, and they contribute 22% of the species that comprise the regional avifauna, which is more than any other habitat type. Key Words: habitat use, Mexico, neotropical migrant birds, riparian, Sonora, wintering. USO DE HABITAT DE COMUNIDADES DE AVES INVERNANTES EN SONORA, MEXICO: IMPORTANCIA DE LOS HABITATS RIPARIOS Resumen. Los sistemas riparios son dinámicos y diversos a pesar de su limitada cobertura espacial. Son especialmente importantes para las comunidades de aves que se reproducen en el Suroeste de los Estados Unidos y son usados extensamente como corredores migratorios; sin embargo, su importancia para las aves invernantes no se ha determinado de forma sistemática.
