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. -
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. -
Amphibian Identification Guide
Amphibian Migrations & Road Crossings Amphibian Identification Guide The NYSDEC Hudson River Estuary Program and Cornell University are working with communities to conserve forests, woodland pools, and the wildlife that depend on these critical habitats. This guide is designed to help volunteers of the Amphibian Migrations & Road Crossings Project identify species they observe during spring migrations, when many salamanders and frogs move from forest habitat to woodland pools for breeding.

Red-Spotted Newt Fact Sheet
WILDLIFE IN CONNECTICUT WILDLIFE FACT SHEET DENNIS QUINN Eastern Red-spotted Newt Notophthalmus v. viridescens Background and Range The red-spotted newt (also commonly referred to as the eastern newt) is widespread and familiar in many areas of Connecticut. Newts have four distinct life stages: egg, aquatic larvae, terrestrial juvenial (or “eft”), and aquatic adult. Their life cycle is one of the most complex of all the salamanders; starting as an egg, hatching into a larvae with external gills, then migrating to terrestrial habitats as juveniles where gills are replaced with lungs, and returning a few years later to their aquatic habitats as adults which retain their lungs. In Connecticut, the newt is found statewide, but more prominently west of the Connecticut River. The red-spotted newt has many subspecies and an extensive range throughout the United States. Description The adult red-spotted newt has smooth skin that is overall greenish in color, with small black dots scattered on the back and a row of several black-bordered reddish-orange spots on each side of the back. Male newts have black rough patches on the inside of their thighs and on the bottom tip of their hind toes during the breeding season. Adult newts are usually 3 to 5 inches in length. The juvenile, or eft, stage of the red-spotted newt is bright orange in color with small black dots scattered on the back and a row of larger, black-bordered orange spots on each side of the back. The skin is rough and dry compared to the moist and smooth skin of adults and larvae. -

Chemical Defense of the Eastern Newt (Notophthalmus Viridescens): Variation in Efficiency Against Different Consumers and in Different Habitats
Chemical Defense of the Eastern Newt (Notophthalmus viridescens): Variation in Efficiency against Different Consumers and in Different Habitats Zachary H. Marion1,2, Mark E. Hay1* 1 School of Biology, Georgia Institute of Technology, Atlanta, Georgia, United States of America, 2 Department of Ecology and Evolutionary Biology, University of Tennessee, Knoxville, Tennessee, United States of America Abstract Amphibian secondary metabolites are well known chemically, but their ecological functions are poorly understood—even for well-studied species. For example, the eastern newt (Notophthalmus viridescens) is a well known secretor of tetrodotoxin (TTX), with this compound hypothesized to facilitate this salamander’s coexistence with a variety of aquatic consumers across the eastern United States. However, this assumption of chemical defense is primarily based on observational data with low replication against only a few predator types. Therefore, we tested the hypothesis that N. viridescens is chemically defended against co-occurring fishes, invertebrates, and amphibian generalist predators and that this defense confers high survivorship when newts are transplanted into both fish-containing and fishless habitats. We found that adult eastern newts were unpalatable to predatory fishes (Micropterus salmoides, Lepomis macrochirus) and a crayfish (Procambarus clarkii), but were readily consumed by bullfrogs (Lithobates catesbeianus). The eggs and neonate larvae were also unpalatable to fish (L. macrochirus). Bioassay-guided fractionation confirmed that deterrence is chemical and that ecologically relevant concentrations of TTX would deter feeding. Despite predatory fishes rejecting eastern newts in laboratory assays, field experiments demonstrated that tethered newts suffered high rates of predation in fish-containing ponds. We suggest that this may be due to predation by amphibians (frogs) and reptiles (turtles) that co-occur with fishes rather than from fishes directly. -
A-231 Forested Peatland Management in Southeast
15TH INTERNATIONAL PEAT CONGRESS 2016 Abstract No: A-231 FORESTED PEATLAND MANAGEMENT IN SOUTHEAST VIRGINIA AND NORTHEAST NORTH CAROLINA, USA Frederic C. Wurster1, Sara Ward2, and Christine Pickens3 1 U.S. Fish and Wildlife Service, Great Dismal Swamp National Wildlife Refuge, Suffolk, VA, USA 2 U.S. Fish and Wildlife Service, Raleigh Field Office, Raleigh, NC, USA 3 The Nature Conservancy, Kill Devil Hills, NC, USA *Corresponding author: [email protected] SUMMARY The U.S. Fish and Wildlife Service manage 130,000 ha of forested peatlands in southeast Virginia and northeast North Carolina, U.S.A. at three national wildlife refuges: Pocosin Lakes, Alligator River, and Great Dismal Swamp. The refuges contain extensive networks of roads and drainage canals; the legacy of past logging and farming activities. Canals have contributed to peat subsidence and facilitated the conversion of wetland forest communities to upland forest communities. During drought periods, drained peat is prone to wildfires that can burn for several months and pose health risks to neighboring communities. Refuge managers are working to restore historic forest communities and stop peat loss through hydrologic restoration, forest management, and fire management. Following four separate severe peat fires on refuges in 2008 and 2011, emphasis has been placed on improving water control capability to support habitat restoration and fire suppression activities. Keywords: Pocosin, forested peatland, peatland restoration, controlled drainage, national wildlife refuge INTRODUCTION The South Atlantic Coastal plain of the United States is home to extensive forested wetlands on peat soils known as pocosins (Richardson, 1991). Also described as evergreen (or southeastern) shrub bogs, the pocosin vegetation community consists of an open-pine canopy underlain by a dense shrub layer. -
