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. -

Blue-Winged and Green-Winged Teals, Are the Marshes, Swamps, and Ponds of Zero to Low Water Movement
BirdWalk Newsletter 1.29.2017 Walk Conducted by: Perry Nugent Newsletter Written by: Jayne J. Matney Photo right by Cary McDonald Blue-winged Teal male with duckweed beak and chest followed by female partner Photo below by Chuck Fuhrman Two Green-winged Teal males This week will be the first in a series of articles covering the ducks of Magnolia Plantation. Most of our duck population is not of permanent residences. Instead, they migrate in for wintering and migrate out for breeding. The males are called “drakes” and the females are called “hens”. Some of these ducks are considered “dabblers”, which means they eat primarily along the surface of the water chewing or filtering from the surface and rarely dive, while others are the “divers”, which do just that-they dive head first into the water for feeding. Dabbling ducks will occasionally dive for food or to escape predators. Photo above left by Chuck Fuhrman Blue-winged Teal Photo above right by Perry Nugent Green-winged Teal The Blue-winged Teal, Anas discors, (above left) and the Green-winged Teal, Anas crecca, (above right) will be discussed this week. They are in the category of dabblers; both species primarily feed off of aquatic plants and seeds from the surface of the water and small larvae, insects, and crustaceans that may be found there as well. Apparently, egg laying females may feed mostly on animal rather than plant during those special times. Both species are small comparatively to other types of ducks, rest out of the water on stumps, rocks and broken branches, and are fast in flight. -

irds find Maine attractive for many of the same reasons we do—the state offers a unique blend of landscapes spanning from mountains to the sea, with forests, grasslands, rivers, marshes, and long coastlines in between. B Where we find beautiful places to hike and kayak, camp and relax, birds find the habitat they need for their survival. But while Maine’s diverse habitats serve an important role for over IBAs 400 bird species—some threatened, endangered, or of regional conservation in concern—the state’s not immune to a growing list of threats that puts these birds at further risk. Habitat loss, degradation, and fragmentation due to development, toxins such as mercury and lead, oil spills on the coast and Maine inland waters, and climate change are top among them. BY ANDREW COLVIN In the face of these threats, a crucial step in conserving Maine’s birds is to identify the areas of the state that are most important for breeding, wintering, and migration. After several years of working toward that goal, Maine Audubon Lists Maine Audubon has recently completed the first phase of its Important 22 of the Most Important Bird Areas (IBA) program, identifying 22 areas across Maine that are vital Places in Maine for Vulnerable Birds to state—and even global—bird populations.
