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. -
Catbird, Gray
Mockingbirds and Thrashers — Family Mimidae 449 Mockingbirds and Thrashers — Family Mimidae Gray Catbird Dumetella carolinensis Though the Gray Catbird breeds west almost to the coast of British Columbia, it is only a rare vagrant to California—the bulk of the population migrates east of the Rocky Mountains. But the species is on the increase: of 107 reports accepted by the California Bird Records Committee 1884–1999, one third were in just the last four years of this interval. Similarly, of the 20 records of the Gray Catbird in San Diego County, 10 have come since initiation of the field work for this atlas in 1997. Migration: Half of San Diego County’s known cat- Photo by Anthony Mercieca birds have been fall migrants, occurring as early as 24 September (1976, one at Point Loma, S7, K. van Vuren, Cabrillo National Monument, Point Loma 11–17 July 1988 Luther et al. 1979). Besides eight fall records from Point (B. and I. Mazin, Pyle and McCaskie 1992) certainly was.

Visual Displays and Their Context in the Painted Bunting
Wilson Bull., 96(3), 1984, pp. 396-407 VISUAL DISPLAYS AND THEIR CONTEXT IN THE PAINTED BUNTING SCOTT M. LANYON AND CHARLES F. THOMPSON The 12 species in the bunting genus Passerina have proved to be a popular source of material for studies of vocalizations (Rice and Thomp- son 1968; Thompson 1968, 1970, 1972; Shiovitz and Thompson 1970; Forsythe 1974; Payne 1982) migration (Emlen 1967a, b; Emlen et al. 1976) systematics (Sibley and Short 1959; Emlen et al. 1975), and mating systems (Carey and Nolan 1979, Carey 1982). Despite this interest, few detailed descriptions of the behavior of any member of this genus have been published. In this paper we describe aspects of courtship and ter- ritorial behavior of the Painted Bunting (Passerina ciris). STUDY AREA AND METHODS The study was conducted on St. Catherines Island, a barrier island approximately 50 km south of Savannah, Georgia. The 90-ha study area (“Briar Field” Thomas et al. [1978: Fig. 41) on the western side of the island borders extensive salt marshes dominated by cordgrasses (Spartina spp.). The tracts’ evergreen oak forest (Braun 1964:303) consists primarily of oaks (Quercus spp.) and pines (Pinus spp.), with scattered hickories (Carya spp.) and palmettos (Sabal spp. and Serenoe repens) also present. Undergrowth was scanty so that buntings were readily visible when on the ground. As part of a study of mating systems, more than 1800 h were devoted to watching buntings during daily fieldwork in the 1976-1979 breeding seasons. In 1976 and 1977 observations commenced the third week of May, after breeding had begun, and continued until breeding ended in early August. -

EFFECTS OF MANAGEMENT PRACTICES ON GRASSLAND BIRDS: LOGGERHEAD SHRIKE Grasslands Ecosystem Initiative Northern Prairie Wildlife Research Center U.S. Geological Survey Jamestown, North Dakota 58401 This report is one in a series of literature syntheses on North American grassland birds. The need for these reports was identified by the Prairie Pothole Joint Venture (PPJV), a part of the North American Waterfowl Management Plan. The PPJV recently adopted a new goal, to stabilize or increase populations of declining grassland- and wetland-associated wildlife species in the Prairie Pothole Region. To further that objective, it is essential to understand the habitat needs of birds other than waterfowl, and how management practices affect their habitats. The focus of these reports is on management of breeding habitat, particularly in the northern Great Plains. Suggested citation: Dechant, J. A., M. L. Sondreal, D. H. Johnson, L. D. Igl, C. M.

Here in North America, birds that live on or near the ground. The sparrows are divided into 13 genera, which also cryptic blend of gray, white, black, and brown includes the towhees (genus Pipilo), longspurs hues which comprise a typical sparrow’s color (genus Calcarius), juncos (genus Junco), and pattern is the result of tens of thousands of Lark Bunting (genus Calamospiza) – all of sparrow generations living in grassland and which are technically sparrows. Emberizidae is brushland habitats. The triangular or cone- a large family, containing well over 300 species shaped bills inherent to most all sparrow species are perfectly adapted for a life of granivory – of crushing and husking seeds. “Of Louisiana’s 33 recorded sparrows, Sparrows possess well-developed claws on their toes, the evolutionary result of so much time spent on the ground, scratching for seeds only seven species breed here...” through leaf litter and other duff.

Gray August 2019 © 2019 Brandan L. Gray. All Rights Reserved. 2 This dissertation titled Ecology, Morphology, and Behavior in the New World Wood Warblers by BRANDAN L. 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.
