A Low Intensity Sampling Method For Assessing Blue Crab Abundance At Aransas National Wildlife Refuge And Preliminary Results On The Relationship Of Blue Crab Abundance To Whooping Crane Winter Mortality, Bruce H. Pugesek, Michael J. Baldwin, Thomas V. Stehn

Proceedings of the North American Crane Workshop

We sampled blue crabs (Callinectes sapidus) in marshes on the Aransas National Wildlife Refuge, Texas from 1997 to 2005 to determine whether whooping crane (Grus americana) mortality was related to the availability of this food source. For four years, 1997 - 2001, we sampled monthly from the fall through the spring. From these data, we developed a reduced sampling effort method that adequately characterized crab abundance and reduced the potential for disturbance to the cranes. Four additional years of data were collected with the reduced sampling effort methods. Yearly variation in crab numbers was high, ranging …

Whooping Crane Collisions With Power Lines: An Issue Paper, Thomas V. Stehn, Tom Wassenich

Proceedings of the North American Crane Workshop

Collision with power lines is the greatest source of mortality for fledged whooping cranes (Grus americana) in the Aransas-Wood Buffalo population (AWBP) that migrate between the Northwest Territories, Canada to the Texas coast. This paper compiles 45 documented whooping crane mortalities from power line strikes in North America and provides known information on crane / power line interactions. A map of the AWBP whooping crane migration corridor was derived with 100 and 200-mile wide corridors delineated showing the location of known mortalities. Recommendations are provided to try to reduce this major threat facing whooping cranes.

A Year-Long Study Of Food Consumption By Captive Whooping Cranes At The International Crane Foundation, Jessica J. Stocking, Michael S. Putnam, Nathanial B. Warning

Proceedings of the North American Crane Workshop

Throughout 2002, we recorded daily food consumption by 12 pairs of captive whooping cranes (Grus americana). For 7 pairs we recorded food consumption throughout the entire year while there were large continuous gaps in measurements of food consumption for 5 pairs that raised chicks that year. Birds received both a maintenance and breeder diet, and for both we converted food consumption to energy intake (Joules/g body mass) using the combined fall weights of female and male. We compared daily energy intake with 6 meteorological variables (involving temperature, wind speed and humidity), photoperiod (natural and artificial) and egg laying …

Resolutions Passed By The North American Crane Working Group, Tenth North American Crane Workshop Zacatecas City, Zacatecas, Mexico, North American Crane Working Group

Proceedings of the North American Crane Workshop

Florida Crane habitat resolution
Florida has the largest population of non-migratory sandhill cranes in the world and winters a significant portion of the eastern population of greater sandhill cranes. And in Florida, efforts are underway to introduce migratory and non-migratory whooping cranes. In order to successfully establish and sustain these populations, appropriate habitat needs to be available. About 40% of Florida’s best crane habitat has been lost between 1973 and 2003, and the amount has increased since then. Because of this, these valuable populations of cranes are finding it more difficult to locate suitable habitat. We the NACWG by this …

Simultaneous Incubation By Two Females And Nestling Provisioning By Four Adults At A Savannah Sparrow Nest, Nathan J. Zalik, Noah G. Perlut

Environmental Studies Faculty Publications

We present the first observations of misdirected parental care by Savannah Sparrows (Passerculus sandwichensis) including a rare occurrence of simultaneous incubation. Two females simultaneously incubated eggs, brooded, and fed nestlings, and two males fed nestlings in one nest. These behaviors may have been prompted by strong parental instincts in combination with a stressful breeding environment mediated by hayfield management, as any genetic benefits were unlikely.

Volatile Compounds From The Integument Of White Leghorn Chickens (Gallus Gallus Domesticus L.): Candidate Attractants Of Ornithophilic Mosquito Species, Ulrich R. Bernier, Sandra A. Allan, Brian Quinn, Daniel Kline, Donald Barnard, Gary Clark

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Candidate kairomones of ornithophilic mosquito species are reported from GC/MS analysis of compounds from the skin on the back, the feet, and feathers from the back of White Leghorn chickens (Gallus gallus domesticus). Hexane and ether extracts of chicken feathers differ significantly in attractiveness of Culex spp. mosquitoes. The active (hexane) extracts contained an abundance of alcohols, ketones, and diones. The inactive (ether) extracts contained aldehydes, which also were in the hexane extracts. Analysis of hexane extracts from chicken feet, skin, and feathers demonstrated the qualitative similarity in the compounds collected with subtle differences observed in the quantitative …

Additions To The Breeding Avifauna Of The Lower Rio Grande Valley Of Texas, Timothy Brush

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

The breeding avifauna of the Lower Rio Grande Valley (LRGV) of Texas has experienced many changes during the 20th century, primarily because of declines in native habitats due to land being converted to agriculture and urban habitats. This paper summarizes changes in breeding avifauna from 2003–2007 in the area. Breeding has been confi rmed for Cooper’s Hawk (Accipiter cooperii), Eurasian Collared-Dove (Streptopelia decaocto), and Mangrove Yellow Warbler (Dendroica petechia oraria) for the fi rst time, and for Gray-crowned Yellowthroat (Geothlypis poliocephala) and Ferruginous Pygmy-Owl (Glaucidium brasilianum) after periods of apparent absence. Short-tailed Hawk (Buteo brachyurus) is a possible breeder, based …

The Birds Of Nebraska, Revised Edition 2007, Paul A. Johnsgard

Papers in Ornithology

Persons living in Nebraska often feel that they are living in a cultural wasteland; its citizenry preoccupied with violent sports such as hunting and football. Yet many are unaware that they are actually residing in one of the prime locations in the entire world for observing and enjoying some of the most aesthetically appealing of all the world's biological attractions. The area around Kingsley Dam and Lake McConaughy, for example, is known to have attracted more than 300 bird species, including 104 breeders (plus 17 probable breeders) making it the third-most species-rich bird location in the entire U.S.A. (after Laguna …

A Guide To The Natural History Of The Central Platte Valley Of Nebraska, Paul A. Johnsgard

Papers in Ornithology

This book has been written in the hope that visitors to the Platte Valley may gain a greater appreciation for it through learning some of its animals and plants in addition to the Platte Valley's star spring attraction, its sandhill cranes. Besides the cranes, we have a world-class migration of geese and ducks, a slightly later migration of shorebirds, including what is probably the buff-breasted sandpiper's most important spring staging area between its South American wintering grounds and its arctic breeding grounds. Nebraska also has what may be the largest surviving population of greater prairie-chickens of any state, and an …

Eurasian Tree Sparrow—A First Record For Nebraska, Mark A. Brogie

Nebraska Bird Review

On Thursday, 01 February 2007, Scott Raasch of rural Madison County called to say he had what he believed to be a Eurasian Tree Sparrow (Passer montanus) coming to a feeder at his house just east of Enola. The bird had been present for about a week, although he had just identified the species upon purchasing a new field guide. He reported that the bird was very wary and only stayed for a short time at the feeder. The bird was most often observed in the early morning or just before dusk.

Dave Heidt and I arrived the …

Fall Field Report, August-November 2007, W. Ross Silcock

Nebraska Bird Review

This was essentially a normal fall season in Nebraska, with no major weather events or significant shifts in breeding or migration ranges, although a possible exception is a first record of Lesser Goldfinch breeding in the state. One observer made the point, though, that the hard freeze in the spring affected seed and fruit crops for fall, most conspicuously resulting in fewer large American Robin flocks. Excellent water conditions in the Rainwater Basin were welcome, but few herons and egrets were present, and no unusual breeding events were reported there.

As winter approached, however, increased numbers of a few finch …

Foraging Behavior And Habitat Use By The Carolina Chickadee (Poecile Carolinensis) In West-Central Indiana, Ihan Chen

All-Inclusive List of Electronic Theses and Dissertations

I studied the effect of environmental conditions on the foraging behavior of Carolina chickadees (Poecile carolinensis) in Kiewig woods, property of Indiana State University, in West Terre Haute in west-central Indiana. My study method uses Optimal Foraging Theory (Brown 1988) to measure the giving up density (GUD) of Chickadees under different environmental conditions ( different resource abundances, different habitat types, different resource types and different seasons). For my experiment, I set up 24 feeding stations in three kinds of habitats ( open area, secondary growth woods and mature woods) within 4 sites and paired trays in each habitat X site. …

Summer Field Report, June-July 2007, W. Ross Silcock

Nebraska Bird Review

This summer was a "something for everyone" season. Ecologists, already excited by the apparent ability of Greater Prairie-Chickens to lek in improbable habitats, such as corn fields and dirt edges of Rainwater Basin playas, will welcome the use by Lark Buntings and Vesper Sparrows of wheat stubble fields with a growing corn crop. The Vesper Sparrows of the east, a different subspecies from those in the north and west, have been at the mercy of full-tillage cropping systems, but now have a reprieve and may even be increasing because of no-till and minimum tillage methods currently in vogue due to …

Fruit Quality And Consumption By Songbirds During Autumn Migration, Susan B. Smith, Kathleen H. Mcpherson, Jeffrey M. Backer, Barbara J. Pierce, David W. Podlesak, Scott R. Mcwilliams

Biology Faculty Publications

Seasonal fruits are an important food resource for small songbirds during autumn migration in southern New England. Therefore, conservation and management of important stopover sites used by migrating birds requires knowledge about nutritional requirements of songbirds and nutritional composition of commonly consumed fruits. We measured nutrient composition and energy density of nine common fruits on Block Island, Rhode Island, and conducted a field experiment to estimate consumption rates of three of these fruits by birds during autumn migration. Most common fruits on Block Island contained primarily carbohydrates (41.3–91.2% dry weight), and little protein (2.6–8.6%) and fat (0.9–3.7%), although three contained …

Lifetime Reproductive Success Of Female Eastern Kingbirds (Tyrannus Tyrannus): Influence Of Lifespan, Nest Predation And Body Size, Michael T. Murphy

Biology Faculty Publications and Presentations

I report on the lifetime reproductive success (LRS) of female Eastern Kingbirds (Tyrannus tyrannus) in central New York. I investigated the major correlates of LRS and specifi cally tested the hypothesis that small body size yields reproductive benefi ts. Lifetime reproductive success varied widely: 15–20% of females failed to fledge young over their life, whereas 50% of young were fledged by 20% of females. Female lifespan varied between one and eight years, and females that died after one breeding season tended to be smaller-bodied than long-lived females (≥2 seasons). I therefore conducted analyses of LRS for the entire sample and …

Spring Field Report, March–May 2007, W. Ross Silcock

Nebraska Bird Review

INTRODUCTION

Extremes of weather conditions and resulting variation in water conditions were noteworthy this spring. The west was very dry, but the Rainwater Basin had ample rains resulting in excellent breeding conditions for various waterbirds, notably Eared Grebe and American Coot. Shorebird numbers were unremarkable, although there was plenty of variation between species. Indeed, Dunlin, with record numbers, and Ruddy Turnstones were numerous. Arrival dates were pushing early but not record early. Species earlier than average were American Golden-Plover, Mountain Plover, Black-necked Stilt, White-rumped Sandpiper, and Stilt Sandpiper.

Increasingly associated with wetlands, albeit unrelated to water levels, Greater Prairie-Chicken continued …

A Preliminary Survey Of Southeast Nebraska Grassland Habitat And Potential Henslow’S Sparrow Habitat, W. Ross Silcock

Nebraska Bird Review

INTRODUCTION

The decline in numbers of Henslow’s Sparrows in North America (Sauer et al. 2001) is generally considered to be due to reduction in the extent of its preferred breeding habitat, “relatively large fields consisting of tall, dense grass, a well-developed litter layer, standing dead vegetation, and sparse or no woody vegetation” (Herkert et al. 2002). Since 1985, however, the Conservation Reserve Program (CRP) has allowed payments to landowners by the United States Department of Agriculture (USDA) through the Farm Service Agency (FSA) to idle croplands and to seed them to various grasses. This has provided habitat that appears to …
