  • 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.

  • Wildland Fire in Ecosystems: Effects of Fire on Fauna
    United States Department of Agriculture Wildland Fire in Forest Service Rocky Mountain Ecosystems Research Station General Technical Report RMRS-GTR-42- volume 1 Effects of Fire on Fauna January 2000 Abstract _____________________________________ Smith, Jane Kapler, ed. 2000. Wildland fire in ecosystems: effects of fire on fauna. Gen. Tech. Rep. RMRS-GTR-42-vol. 1. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 83 p. Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals’ ability to thrive in the altered, often simplified, structure of the postfire environment. The extent of fire effects on animal communities generally depends on the extent of change in habitat structure and species composition caused by fire. Stand-replacement fires usually cause greater changes in the faunal communities of forests than in those of grasslands. Within forests, stand- replacement fires usually alter the animal community more dramatically than understory fires. Animal species are adapted to survive the pattern of fire frequency, season, size, severity, and uniformity that characterized their habitat in presettlement times. When fire frequency increases or decreases substantially or fire severity changes from presettlement patterns, habitat for many animal species declines. Keywords: fire effects, fire management, fire regime, habitat, succession, wildlife The volumes in “The Rainbow Series” will be published during the year 2000.

  • GRAY CATBIRDS by Mike Scully
    GRAY CATBIRDS By Mike Scully (This article first appeared in the August 2010 SAAS newsletter.) It is interesting how different cultures can evolve quite different perceptions of the same bird. The Gray Catbird (Dumetella carolinensis), for example, is seemingly one of our more descriptively named species. Their common call does indeed bring to mind the mewing of a domestic cat, but only to those familiar with cats. Arthur C. Bent, in his epochal work, “Life Histories of North American Birds,” states that the Chippewa people of the American Midwest called this species “the bird that cries with grief.” Bent puzzled in print how the Chippewa could find the pleasant song of the catbird mournful. I believe they were referring not to the song, but to the distinctive call. It can come as a minor paradigm shift when one realizes that the plaintive call of this species does indeed possess a dirge-like quality. Gray Catbird perched on American Beautyberry. Photo by Lora Reynolds. Certainly the catbird was familiar to many of the original inhabitants of North America, much as it remains today; an attractive gray bird, slipping low between brush tangles, the frequency of its songs and calls belying any impression of secrecy. The Gray Catbird possesses two attributes that doubtless help it succeed in human-altered landscapes; it prefers dense edge and early successional habitats, and it possesses a faculty for recognizing and rejecting the eggs of the Brown-headed Cowbird. The present breeding range includes the majority of North America, but they are absent from the Far North, the Florida Peninsula, much of the Southwest, the Great Basin and our Pacific Coast.

  • Pre-Lesson Plan
    Pre-Lesson Plan Prior to taking part in the Winged Migration program at Tommy Thompson Park it is recommended that you complete the following lessons to familiarize your students with some of the birds they might see and some of the concepts they will learn during their field trip. The lessons can easily be integrated into your Science, Language Arts, Social Studies and Physical Education programs. Part 1: Amazing Birds As a class, read the provided “Wanted” posters. The posters depict a very small sampling of some of the amazing feats and features of birds. To complement these readings, display the following websites so that students can see some of these birds “up close.” Common Loon http://www.schollphoto.com/gallery/thumbnails.php?album=1 Black-Capped Chickadee http://sdakotabirds.com/species_photos/black_capped_chickadee.htm Ruby-Throated Hummingbird http://www.surfbirds.com/cgi-bin/gallery/search2.cgi?species=Ruby- throated%20Hummingbird Downy Woodpecker http://www.pbase.com/billko/downy_woodpecker Great Horned Owl www.owling.com/Great_Horned.htm When you visit Tommy Thompson Park, you may see chickadees, hummingbirds, and woodpeckers. These birds all breed in southern Ontario. However, you probably will not see a Great Horned Owl, because this specific bird is usually flying around at night. Below is a list of some other birds students might see when they visit Tommy Thompson Park. Have them chose one bird each and write a “Wanted” poster for it, focusing on a cool fact about that bird.

  • Gray Catbird, Northern Mockingbird and Brown Thrasher
    Wildlife Note — 51 LDR0103 Gray Catbird, Northern Mockingbird and Brown Thrasher by Chuck Fergus Gray Catbird These three species are among the most vocal of our birds. All belong to Family Mimidae, the “mimic thrushes,” or “mimids,” and they often imitate the calls of other spe- cies, stringing these remembered vocalizations into long, variable songs. Family Mimidae has more than 30 spe- cies, which are found only in the New World, with most inhabiting the tropics. The mimids have long tails and short, rounded wings. The three species in the Northeast are solitary (living singly, in pairs and in family groups rather than in flocks), feed mainly on the ground and in shrubs, and generally eat insects in summer and fruits in winter. The sexes look alike. Adults are preyed upon by owls, hawks, foxes and house cats, and their nests may be raided by snakes, blue jays, crows, grackles, raccoons, opossums and squirrels.

Major factors affecting feeding were nestling age and brood size. The averagenumber of food deliveries.brood-•. h-• increasedlinearly with the log of nestlingage for both male and femaleparents. Also, volumeof food delivered/feedingtrip increasedlinearly with nestling age. As brood size increased,feeding frequencies/brood increasedbut food deliveries/nestlingdecreased. Brooding and shadingwere affectedmainly by nestlingage and ambient temperature.Time spent brooding decreasedsubstantially as nestlingsgrew older. Shading was important when the sun shone directly on the nest.
