Effects Of Human Disturbances On The Behavior Of Wintering Ducks, Melissa L. Pease, Robert K. Rose, Mark J. Butler Jan 2005

Effects Of Human Disturbances On The Behavior Of Wintering Ducks, Melissa L. Pease, Robert K. Rose, Mark J. Butler

Biological Sciences Faculty Publications

Human activity causes wintering waterfowl to expend energy to avoid humans at a time in their annual cycle when energy conservation is important to survival, migration, and breeding reserves. Understanding the effects of recreational activities on waterfowl is important to managing natural resource areas where migratory birds depend on wetland habitat for resting and feeding. We investigated responses of 7 species of dabbling ducks to 5 different experimental human activities, (a pedestrian, a bicyclist, a truck traveling at 2 different speeds, and an electric passenger tram). Responses of ducks depended on type of disturbance, species, and distance from disturbances. Most …


Effect Of Dietary Fatty Acid Composition On Depot Fat And Exercise Performance In A Migrating Songbird, The Red-Eyed Vireo, Barbara J. Pierce, Scott R. Mcwilliams, Timothy P. O'Connor, Allen R. Place, Christopher G. Guglielmo Jan 2005

Effect Of Dietary Fatty Acid Composition On Depot Fat And Exercise Performance In A Migrating Songbird, The Red-Eyed Vireo, Barbara J. Pierce, Scott R. Mcwilliams, Timothy P. O'Connor, Allen R. Place, Christopher G. Guglielmo

Biology Faculty Publications

Most migrating birds accumulate lipid stores as their primary source of energy for fueling long distance flights. Lipid stores of birds during migration are composed of mostly unsaturated fatty acids; whether such a fatty acid composition enhances exercise performance of birds is unknown. We tested this hypothesis by measuring metabolic rate at rest and during intense exercise in two groups of red-eyed vireos, a long-distance migratory passerine, fed either a diet containing 82% unsaturated fat (82%U), or one containing 58% unsaturated fat (58%U). Vireos fed the 82%U diet had fat stores containing (77%) unsaturated fatty acids, whereas vireos fed the …


Habitat Patch Occupancy Dynamics Of Glaucous-Winged Gulls (Larus Glaucescens) Ii: A Continuous-Time Model, Smruti P. Damania, Karl W. Phillips, Shandelle M. Henson, James L. Hayward Jan 2005

Habitat Patch Occupancy Dynamics Of Glaucous-Winged Gulls (Larus Glaucescens) Ii: A Continuous-Time Model, Smruti P. Damania, Karl W. Phillips, Shandelle M. Henson, James L. Hayward

Faculty Publications

The diurnal distribution and abundance dynamics of loafing Glaucous-winged Gulls (Larus glaucescens) were examined at Protection Island National Wildlife Refuge, Strait of Juan de Fuca, Washington. Asynchronous movement of gulls among three habitat patches dedicated to loafing was modeled as a function of environmental variables using differential equations. Multiple time scale analysis led to the derivation of algebraic models for habitat patch occupancy dynamics. The models were parameterized with hourly census data collected from each habitat patch, and the resulting model predictions were compared with observed census data. A four-compartment model explained 41% of the variability in the data. Models …

Habitat Patch Occupancy Dynamics Of Glaucous-Winged Gulls (Larus Glaucescens) I: A Discrete-Time Model, Karl W. Phillips, Smruti P. Damania, James L. Hayward, Shandelle M. Henson, Clara J. Logan

Faculty Publications

Diurnal habitat occupancy dynamics of Glaucous-winged Gulls were evaluated in a system of six habitats on and around Protection Island, Washington. Data were collected on the rates of gull movement between habitat patches, and from these data the probabilities of transitions between habitats were estimated as functions of tide height and time of day. A discrete-time matrix model based on the transition probabilities was used to generate habitat occupancy predictions, which were then compared to hourly census data. All model parameters were estimated directly from data rather than through model fitting. The model made reasonable predictions for two of the …

Management Of Cattail (Typha Spp.) Stands With Glyphosate To Disperse Blackbirds, George M. Linz, H. Jeffrey Homan, Ryan L. Wimberly, Philip Mastrangelo, William J. Bleier Oct 2004

Management Of Cattail (Typha Spp.) Stands With Glyphosate To Disperse Blackbirds, George M. Linz, H. Jeffrey Homan, Ryan L. Wimberly, Philip Mastrangelo, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

In the Prairie Pothole Region of North Dakota and South Dakota, blackbirds (Icteridae) gather by the thousands in large premigratory roosts in late summer and early fall. Wetlands dominated by cattails (Typha spp.) provide ideal roosting habitat for these aggregations. Sunflower fields near large roosts can receive substantial damage. To eliminate potential roosting sites, Wildlife Services of the United States Department of Agriculture has implemented a cattail management program that aerially sprays dense cattail stands with the herbicide glyphosate m-(phosphonomethyl) glycine]. The continued viability of the program depends on a positive benefit-cost ratio and minimal environmental impacts. In this …


The Greater Snow Goose (Chen Caerulescens Atlanticus) In Nebraska, W. Ross Silcock Sep 2004

The Greater Snow Goose (Chen Caerulescens Atlanticus) In Nebraska, W. Ross Silcock

Nebraska Bird Review

Recently, Mr. William Lemburg of Cairo, Nebraska, in a letter to the Editor of the Nebraska Bird Review, noted the following: "I have a friend who does quite a bit of goose hunting. He remarked to me that during the spring snow goose season, he occasionally shoots an extra-large Snow. Thinking that maybe a few Greater Snows that winter along the Atlantic Coast may end up in the Central Flyway, I asked him to save the head of one if he bagged one the following season. This is about five years ago. The following season he did get one. …

Annual Meeting At Ogallala [June 2004]

Nebraska Bird Review

The Nebraska Ornithologists' Union 2004 Annual Meeting took place at Ogallala on May 14-16, with field trips centering around Lake McConaughy and Lake Ogallala. A total of 190 species was counted over the weekend. The low water level in Lake McConaughy provided excellent habitat for 21 species of waterfowl, 27 species of shorebirds, including nesting Snowy and Piping Plovers, and a Great Black-backed Gull. More surprising were the 17 warbler species, including Blue-winged, Northern Parula, Black-throated Green, Palm, Bay-breasted, and Kentucky. The meeting also offered participants the chance to study many eastern and western species pairs, including Rose-breasted and Black-headed …

In Explorers' Footsteps: You Can Find Nearly All The Birds Documented By Lewis And Clark In Great Refuges On The Great Plains, Paul A. Johnsgard

Papers in Ornithology

Two hundred years ago this May, Meriwether Lewis and William Clark, together with the three dozen army volunteers and hired hunter-interpreters who made up the Corps of Discovery, departed their winter camp at the mouth of the Missouri River, north of St. Louis, Missouri, and set out to make history. President Thomas Jefferson had charged them with the monumental task of exploring the unknown lands of the Louisiana Territory, purchased from France the year before, and trying to find a navigable route to the Pacific Ocean via the Missouri River. The explorers were also asked to make extensive geological, geographic, …

Juvenile And Adult Survival In The Sociable Weaver (Philetairus Socius), A Southern-Temperate Colonial Cooperative Breeder In Africa, Rita Covas, Charles R. Brown, Mark D. Anderson, Mary Bomberger Brown

School of Biological Sciences: Faculty Publications

We used capture–recapture analyses to describe juvenile and adult survival from 1993 to 2001 in a population of Sociable Weavers (Philetairus socius), a colonial, cooperatively breeding passerine of southern Africa. We examined temporal variation in survival and the role that the breeding season’s length and environmental factors play in determining survival patterns in the population. Annual survival probability (mean ± SE) was 0.66 ± 0.02. In contrast to most passerines, juveniles and adults had similar survival probabilities; survival rates did not vary significantly between years. We found no relationship among temperature, rainfall, and survival. Relatively high survival rates …
