Food And Energy Intake Rates Of Wintering Whooping Cranes Foraging On Two Selected Food Items, Felipe Chavez-Ramirez, Jay T. Nelson, R. Douglas Slack

Proceedings of the North American Crane Workshop

Number, mass, and potential energy of food items consumed by wintering whooping cranes (Grus americana) foraging on blue crab (Callinectes sapidus) and woltberry (Lycium carolinianum) fruit were estimated and compared between 2 consecutive winter periods. Mass consumed was determined through field observations by quantifying the number of items taken per unit time and the average, or modal, weight of each food item determined from collections. Gross energy intake was determined by calculating the product of mass consumed times gross energy (kJ/g) of each food item. Potential energy retained was calculated by determining metabolizable energy …

Semen Collection And Fertility In Naturally Fertile Sandhill Cranes, Guojun Chen, George F. Gee, Jane M. Nicolich, Joanna A. Taylor

Proceedings of the North American Crane Workshop

Aviculturists often ask if semen collection will interfere with fertility in naturally fertile pairs of cranes. We used 12 naturally fertile Florida sandhill crane (Grus canadensis pratensis) pairs for this study, 6 control and 6 experimental. All pairs had produced fertile eggs in previous years and were in out-of-doors pens scattered throughout different pen complexes, within auditory range but physically isolated. Semen was collected on Tuesday mornings and Friday afternoons from 26 February 1993 to 4 June 1993. We used standard artificial insemination methods to collect and to evaluate the semen and spermatozoa. Semen collection did not affect semen quality …

Results Of Eight Years Of Predator Control To Enhance Sandhill Crane Production On Malheur National Wildlife Refuge, Oregon, Gary L. Ivey

Proceedings of the North American Crane Workshop

Because of a 21 % decline in breeding pairs of greater sandhill cranes (Grus canadensis tabida) on Malheur National Wildlife Refuge from 1971 to 1985, a predator control program was initiated in 1986 to enhance production. The primary cause for the decline was low recruitment of young due to high predation by ravens (Corvus corax). raccoons (Procyon lotor), and coyotes (Canis latrans), On average, predators destroyed 46% of all crane nests and 90% of the prefledged colts. Mink (Mustela vison) were added to the program in 1993 after a study …

Long Bone Fracture Management In A Sandhill Crane: A Case Report, Patrice N. Klein, Dorothy Thompson

Proceedings of the North American Crane Workshop

A 65-day-old, juvenile Mississippi sandhill crane (Grus canadensis pulla) sustained an oblique fracture of the right middiaphyseal femur. Internal fixation by use of an intramedullary pin and full cerclage wire was performed to stabilize the fracture site. Post-operative medical management of these fractures is often unsuccessful due to secondary complications associated with long-term restraint. This report describes the successful recovery of an endangered sandhill crane with a long bone fracture of the pelvic limb through a program of incremental physical therapy beginning 2 weeks post-femoral fracture repair. Sling support, assisted walking, and hydrotherapy were methods effective in preventing …

Resolutions Passed By The North American Crane Working Group

Proceedings of the North American Crane Workshop

RECOGNITION OF THE CONTRIBUTIONS OF TOM TACHA TO CRANE RESEARCH

Participants of the Seventh North American Crane Workshop wish to recognize Tom Tacha's many contributions to the understanding of Mid-continent sandhill crane behavior, ecology, and taxonomy. Tom published 30 papers on cranes between 1979 and 1995 and was chief editor of Migratory Shore and Upland Game Bird Management in North America, published shortly before his death. Tom's Ph.D. work and other morphological and behavioral studies strongly influenced our notions of the boundaries among, and validity of. the 3 migratory sandhill crane subspecies. He set new standards for quantitative analysis of …

Effects Of Two (Diptera: Culicidae) Mosquito Control Agents On Growth And Reproduction Of Red-Winged Blackbirds (Agelaius Phoeniceus), Joann M. Hanowski, Gerald J. Niemi, Ann R. Lima, Ronald R. Regal

Journal of the Minnesota Academy of Science

We compared red-winged blackbird (Agelaius phoeniceus) reproductive success and nestling growth in 1988 in 10 wetland site treated with methoprene and 10 sites treated with Bacillus thuringiensis israelensis (Bti) to 30 sites that had never received any mosquito (Diptera: culicidae) control treatment. No differences were detected between reference and treatment sites for clutch size, egg volume, growth rates, or fledge weight. The probability that an egg survived to the nestling stage was greater in methoprene-treated than reference sites. No other differences were detected among sites for reproductive success estimated using the Mayfield method. We conclude that treatment of the wetlands …

The Foraging Ecology And Habitat Selection Of The Yellow-Plumed Honeyeater (Lichenostomus Ornatus) At Dryandra Woodland, Western Australia, Kellie Wilson

Theses : Honours

The foraging ecology and habitat selection of the Yellow-plumed Honeyeater was examined using observations and vegetation surveys at Dryandra Woodland, Western Australia. Foraging ecology data was collected over three seasons (autumn, winter and spring) in 1997 at three sites within Dryandra. Habitat selection studies involved 156 sites being surveyed for the presence or absence of the Yellow-plumed Honeyeater. The vegetation characteristics of the site were measured. Yellow-plumed Honeyeaters foraged by gleaning foliage most of the time. Bark and aerial foraging were also common. Birds clearly selected for tree height, preferring to forage on larger (older) trees which may be because …

The Birds Of Perth's Urban Parks : Factors Influencing Their Distribution And Community Attitudes Towards Them, Jodi S. Mansell

Theses : Honours

Knowledge of the general responses of bird populations to urbanisation and an understanding of their habitat requirements is necessary to ensure the continuation of bird life in urban areas. Most of the literature on urban birds around the world has concentrated on birds in streets and remnant patches. Urban parks provide much potential habitat for birds, although there are few publications addressing this issue. The aims of this project were to determine the terrestrial avifauna of Perth's northern suburban parks, investigate physical factors that might influence the distribution of birds, and determine the attitudes of park users towards birds in …

Some Aspects Of The Ecology Of An Urban Corvid : The Australian Raven (Corvus Coronoides) In Metropolitan Perth, P. J. Stewart

Theses : Honours

The relatively recent and noticeable increase in abundance and distribution of the Australian Raven (Corvus coronoides) in the Perth metropolitan area, has led to an increase in the amount of problems associated with the bird resulting in a need to quantify its ecology in an urban context. This research documented the abundance and distribution of the raven, possible reasons for its increase, the basic nesting characteristics, peoples attitudes, basic morphology, food items and problems associated with the bird in Perth and Kings Park. These aims were achieved by using observational field data, culled birds, a newspaper questionnaire and Geographic Information …

Whooping Crane Sightings, August-December 1996, Steven Anschutz

Nebraska Bird Review

Based on observations of the breeding grounds during the summer of 1996, about 170 Whooping Cranes were expected to arrive at the Aransas National Wildlife Refuge in Texas during the fall. The first arrival (two birds) was confirmed on 23 October. A total of 158 birds (143 adults/subadults and 15 young) were wintering at Aransas 1996-97. As of 16 January 1997, six adults and eight subadults, of the number anticipated, had not arrived at the refuge.

The first recorded dates for confirmed observations of migrating Whooping Cranes were 2 August in Canada and 22 September in the United States. The …

Fall Field Report, August-November 1996, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

This fall we received numerous excellent reports from which to compile this summary. Most parts of the state are covered, except the southwest and north central, although many observers at least pass through those areas. A note about details on unusual observations. The new NOU Field Card, which can be ordered by sending a stamped, self-addressed envelope to the NOU Librarian, Univ of Nebraska State Museum, Lincoln, NE 68588-0514, indicates species that need complete documentations, mostly casual and accidental species. However, we realize that information about early and late migration dates, and rarity in the west or east is not …

A Re-Evaluation Of Hotspot Settlement In Lekking Sage Grouse, Robert M. Gibson

School of Biological Sciences: Faculty Publications

Recent analyses of avian leks have come to conflicting conclusions concerning the role of male settlement on female traffic hotspots. This issue was re-examined in the sage grouse, Centrocercus urophasianus, using data on prenesting movements of radio-tagged females and the dispersion of lekking males collected during a 10-year field study. As expected with hotspot settlement, leks were preferentially located in areas through which females traveled between wintering and nesting ranges before mating. In addition, the distribution of males among leks was related proximately to variation in numbers of females visiting each lek during the mating period and ultimately to …

Brown-Headed Cowbird (Molothrus Ater) Range Expansion Into The Southeast: Effects On The Passerine Populations Using North American Breeding Bird Survey Data, Elizabeth Pruitt Henderson

Biological Sciences Theses & Dissertations

North American Breeding Bird Survey data that were collected from 1971-1992 in Virginia, North Carolina, south Carolina, Georgia, Florida, Alabama and Tennessee were used in this analysis of the impact of Brown-headed Cowbird range expansion on four warbler and four vireo host species.

Maps of mean cowbird abundances were produced using kriging for the periods 1971-1975, 1976-1980, 1981-1985, 1986-1990 and 1991-1992. These maps illustrated a complex invasion of the southeastern United States by Brown-headed Cowbird.

Linear regression analyses of host and cowbird abundances within physiographic strata, showed no species to be in decline or increasing in abundance over the entire …

Collision Course: The Hazards Of Lighted Structures And Windows To Migrating Birds, Lesley J. Evans Ogden

Fatal Light Awareness Program (FLAP)

The collision of migrating birds with human-built structures and windows is a world-wide problem that results in the mortality of millions of birds each year in North America alone. Birds killed or injured at such structures are due to two main factors. The first of these is the lighting of structures at night, which “traps” many species of nocturnal migrants. The second factor contributing to the hazard is the presence of windows, which birds in flight either cannot detect, or misinterpret. In combination, these two factors result in a high level of direct anthropogenic (human-caused) mortality. Bird mortality at human-built …

A Late Baird's Sandpiper In Keith County, Stephen J. Dinsmore

Nebraska Bird Review

On 23 December 1994, Gordon Brown and I were walking the North Platte River below Keystone Dam as part of the Lake McConaughy Christmas Bird Count (CBC). At approximately 8:30 a.m. MST, about 0.5 mi below the dam, we observed a group of 8 Killdeer and a smaller shorebird, which we immediately recognized as a "peep." We studied the bird for about 30 minutes at distances as close as 40 feet and then returned in the afternoon to photograph it. The size and black legs immediately eliminated Least Sandpiper, and the dark rump eliminated White-rumped Sandpiper. The remaining possibilities were …

A Review Of The Status Of Limnodromus Griseus, The Short-Billed Dowitcher, In Nebraska, Joel Jorgensen

Nebraska Bird Review

The two North American dowitchers are notoriously difficult to distinguish from each other. This is not only true of field observations, but there are several instances where a specimen identified as one species was found to be the other upon review. Limnodromus scolopaceus, the Long-billed Dowitcher, has always been considered the common dowitcher in Nebraska, while Limnodromus griseus, the Short-billed Dowitcher, is less common. Confusion about identification and the lack of consistent, well-documented records have caused the status of L. griseus in Nebraska to be a matter of speculation.

Taxonomy of dowitchers was for some time confused. Studies …

Another Common Crane In Nebraska With A Summary Of North American Records, Gary Lingle

Nebraska Bird Review

On 30 March 1996 around 1000 h CST, Bob Janssen and Jim Williams of Minnetonka, Minnesota, discovered a Common Crane (Grus grus) feeding in corn stubble with a flock of Sandhill Cranes (Grus canadensis) in Section 34 T9R10 Hall County, Nebraska. The Commom Crane associated with the Sandhill Cranes, which were at peak numbers in the Platte River valley. Later that day, several observers, including myself, witnessed the bird in section 32 about 500 yards away, where it mingled with a few hundred Sandhill Cranes. The difficulty in seeing this bird was illustrated by the fact …

Female Choice In Sage Grouse: The Roles Of Attraction And Active Comparison, Robert M. Gibson

School of Biological Sciences: Faculty Publications

Previous studies of female choice in sage grouse Centrocercus urophasianus have implicated both the acoustic quality and repetition rate of the stereotyped strut display as putative cues for female choice. Stages in the choice process at which specific components of male courtship display influence female decisions were investigated using field observations of female premating behavior. Females visited a subset of territorial males and then actively chose one of these as a mate. The order in which males were visited suggested that females searched until an acceptable mate was found, rather than employing a “best-of-n” tactic. Numbers of females visiting a …

Whooping Crane Sightings During March-May 1996 Migration, Steven Anschutz

Nebraska Bird Review

A peak population of 158 whooping cranes (130 adult/subadult and 28 juvenile) was reported at the Aransas National wildlife Refuge in Texas during the winter of 1995-96. One juvenile was believed to have died between March 17 and 20, so 157 cranes began the spring migration, an increase of 24 birds over 133 in spring, 1995. By April 4, about 82 cranes had begun to migrate, and by April 25, only 9 cranes remained at Aransas. All but 2 of these had migrated by May 3. One of the two cranes migrated sometime after May 22, but the other bird …
