Brown Pelican
118 Pelicans — Family Pelecanidae Brown Pelican Pelecanus occidentalis The failure of Brown Pelican nesting in southern California in the late 1960s and early 1970s, and its link to DDT, was a key case alerting the world to the unintended ill effects of persistent pesticides. Happily, once the release of DDT in the United States was banned, the pelicans recovered quickly. By the 1990s Brown Pelican was again common along San Diego County’s coast, numbers peaking in late summer and early fall. Nevertheless, the popu- lation remains fragile, and in California the Brown Pelican is still formally listed as an endangered spe- cies. The nesting colony nearest San Diego County is on Los Coronados Islands off Tijuana. Winter: The Brown Pelican is common all along San Diego County’s coast, as well as over the nearby ocean.

Predation by Gray Catbird on Brown Thrasher Eggs
March 2004 Notes 101 PREDATION BY GRAY CATBIRD ON BROWN THRASHER EGGS JAMES W. RIVERS* AND BRETT K. SANDERCOCK Kansas Cooperative Fish and Wildlife Research Unit, Division of Biology, Kansas State University, Manhattan, KS 66506 (JWR) Division of Biology, Kansas State University, Manhattan, KS 66506 (BKS) Present address of JWR: Department of Ecology, Evolution, and Marine Biology, University of California, Santa Barbara, CA 93106 *Correspondent: [email protected] ABSTRACT The gray catbird (Dumetella carolinensis) has been documented visiting and breaking the eggs of arti®cial nests, but the implications of such observations are unclear because there is little cost in depredating an undefended nest. During the summer of 2001 at Konza Prairie Bio- logical Station, Kansas, we videotaped a gray catbird that broke and consumed at least 1 egg in a brown thrasher (Toxostoma rufum) nest. Our observation was consistent with egg predation because the catbird consumed the contents of the damaged egg after breaking it. The large difference in body mass suggests that a catbird (37 g) destroying eggs in a thrasher (69 g) nest might risk injury if caught in the act of predation and might explain why egg predation by catbirds has been poorly documented. Our observation indicated that the catbird should be considered as an egg predator of natural nests and that single-egg predation of songbird nests should not be attributed to egg removal by female brown-headed cowbirds (Molothrus ater) without additional evidence. RESUMEN El paÂjaro gato gris (Dumetella carolinensis) ha sido documentado visitando y rompien- do los huevos de nidos arti®ciales, pero las implicaciones de dichas observaciones no son claras porque hay poco costo por depredar un nido sin defensa. -
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. -

Brief Description of Project
Detailed Background on Existing Resource Conditions in Project/Study Area Giacomini Wetland Restoration Project Golden Gate National Recreation Area/ Point Reyes National Seashore Land Use: The Giacomini Ranch has been used for dairy farming since 1917. The Giacominis established their operation in the 1940s with diking of what is now referred to as the East and West Pastures and are still farming the ranch currently. The National Park Service’s reservation of use agreement with the Giacominis ends in 2007 at which the dairy operation will cease, and the entire 563 acres will be under the National Park Service (Park Service) ownership and management. Olema Marsh, which is directly south of the Giacomini Ranch in the Olema Valley, has been owned by the non-profit organization, Audubon Canyon Ranch. The marsh is primarily used by the public for walking, birding, and sightseeing opportunities. The West Marin area, including Point Reyes National Seashore (Seashore) and north district of Golden Gate National Recreation Area (GGNRA), is largely rural and comprised of agricultural operations and small residential communities. The dominant type of agriculture within the region is dairy and beef cattle operations. South of Olema Marsh lies pasturelands that are owned by the Park Service and grazed under lease by beef cattle. Leased beef cattle grazing also occurs near Park Service land at Railroad Point northeast of the Giacomini Ranch. Otherwise, most of the Giacomini Ranch and Olema Marsh is surrounded by the towns of Point Reyes Station and Inverness Park, which consist largely of residential homes and small businesses. To the north of Giacomini Ranch lies undiked marshlands that are owned by the State Lands Commission. -
Patterns of Co-Occurrence in Woodpeckers and Nocturnal Cavity-Nesting Owls Within an Idaho Forest

Research Paper Patterns of co-occurrence in woodpeckers and nocturnal cavity- nesting owls within an Idaho forest Micah N. Scholer 1, Matthias Leu 2 and James R. Belthoff 1 1Department of Biological Sciences and Raptor Research Center, Boise State University, Boise, Idaho, USA, 2Biology Department, College of William and Mary, Williamsburg, Virginia, USA ABSTRACT. Few studies have examined the patterns of co-occurrence between diurnal birds such as woodpeckers and nocturnal birds such as owls, which they may facilitate. Flammulated Owls (Psiloscops flammeolus) and Northern Saw-whet Owls (Aegolius acadicus) are nocturnal, secondary cavity-nesting birds that inhabit forests. For nesting and roosting, both species require natural cavities or, more commonly, those that woodpeckers create. Using day and nighttime broadcast surveys (n = 150 locations) in the Rocky Mountain biogeographic region of Idaho, USA, we surveyed for owls and woodpeckers to assess patterns of co-occurrence and evaluated the hypothesis that forest owls and woodpeckers co-occurred more frequently than expected by chance because of the facilitative nature of their biological interaction. We also examined co-occurrence patterns between owl species to understand their possible competitive interactions. Finally, to assess whether co-occurrence patterns arose because of species interactions or selection of similar habitat types, we used canonical correspondence analysis (CCA) to examine habitat associations within this cavity-nesting bird community. -
Factors Affecting Feeding and Brooding of Brown Thrasher Nestlings.-The Nest- Ling Period Is a Particularly Stressful Time in the Lives of Birds
GENERAL NOTES 297 wind. An adult California Gull (Larus c&ornicus) was flying east 5 m above the water, 50 m from the shore, close to 150 Barn Swallows (Hirundo rustica) that were foraging low over the water. One swallow, heading west, passed 1 m below the gull, which dropped suddenly and caught the swallow with its bill, glided for a few meters and settled on the water. The gull proceeded to manipulate the swallow in its bill for 30 set before swallowing the still moving bird head first. The gull sat on the water for 20 min, then continued its flight to the east. Most reports of adult birds being taken by gulls have occurred while the prey were on land or water, e.g., Manx Shearwater (Puffi nus &&us) and Common Puffins (Fratercula arctica) in nesting colonies as they go to and from their burrows (Harris 1965), sick or injured birds up to the size of geese (Witherby 1948), Rock Doves (Columba &via) (Jyrkkanen 1975) and Eurasian Starlings (Sturnus vulgaris) (Drost 1958) at grain piles and ground-dwelling birds which associate with gulls (e.g., Witherby 1948). Gull predation of adult birds on water is much rarer but does occur (Hafft, Condor 73:253, 1971). Attacks and capture of avian prey on the wing has rarely been reported and generally occurs over sea on migration (Drost 1958). Bannerman (1962) reports Herring Gulls (L. argentatus) capturing and eating Redwings (Turdus musicus) and Eurasian Blackbirds (2.’ merula) as they migrate over water by knocking the weary birds into the water. -
