Nebraska's Sandhill Crane Population, Past, Present, And Future, Paul A. Johnsgard

Nebraska Bird Review

Although the spring concentrations of Sandhill Cranes in Nebraska's Platte Valley are now an avian phenomenon known nationwide, a general appreciation and inventory of this unique concentration of birds has only been attempted in the last few decades. I am often asked how long this largest of all crane concentrations has been occurring in the Platte Valley, and why it has developed only there. Here I will try to summarize the little-known history of this marvelous assemblage, but not dwell on the ecological reasons for it. The latter are now generally well understood to revolve around abundant spring food supplies …

Fall Field Report, August-November 2002, W. Ross Silcock

Nebraska Bird Review

A few words on documentation of sightings reported is in order. I receive many reports each season of rare or hard-to-identify birds. If they fit a pattern that has developed over the years (see "Birds of Nebraska"), I tend to accept them as correct. However, if they fall outside the range of prior reports, I usually email the observer and ask for some details about the identification and circumstances of the sighting. Everyone has been very nice about this process; observers sometimes take these requests as a questioning of their ability, but I haven't run into this problem with Nebraska …

Immunocontraception In Japanese Quail Using Mammalian Gnrh Compared To Chicken Gnrh-I And Chicken Gnrh-Ii, Marianna Burks

Open Access Master's Theses (through 2010)

Because of increasing numbers in wildlife, immunocontraceptives are being developed to decrease these animals and other birds. This study was conducted in conjunction with the United States Geological Survey Midcontinent Science Center in Fort Collins, Colorado (USGS), to determine whether mammalian GnRH (m-GnRH) can be used as a potential immunocontraceptive to decrease reproductive fertility in mature Japanese quail.

Eighty male and female Japanese quail were injected with either mGnRH, chicken GnRH-I (c-GnRH-I), chicken GnRH-II (c-GnRH-II), or vehicle (controls). Blood samples were analyzed for estrogen (E2) and testosterone (T) levels, in addition to antibody titer (Aby) development against the corresponding conjugated …

Individual, Temporal, And Seasonal Variation In Sperm Concentration In Tree Swallows, Michael P. Lombardo, Armetris N. Forman, Matthew R. Czarnowski, Patrick A. Thorpe

Peer Reviewed Publications

We determined sperm concentrations in Tree Swallows (Tachycineta bicolor) by manually expressing semen samples from males during prelaying, egg-laying, incubation, and nestling periods. Sperm concentrations varied by orders of magnitude (0-10⁹ sperm mL^-1) among males. Sperm concentrations were highest during the incubation period and lowest during the prelaying period. None of the samples collected during the prelaying, egg-laying, and incubation periods were devoid of sperm. In contrast, 45% of samples collected during the nestling period lacked sperm. Sperm concentrations (1) did not vary over the course of the morning during prelaying, egg-laying, and incubation periods …

Hermit Warbler In Knox County: First Accepted Record For Nebraska, Mark A. Brogie

Nebraska Bird Review

The 2002 Nebraska Ornithologists' Union Record Committee has reviewed the following record and accepted it as a Class III. This Knox County sighting constitutes the first confirmed record of Hermit Warbler in Nebraska.

On 15 May, 2002, while birding with Ben Brogie, we stopped at an isolated planting of mixed hardwoods and Ponderosa Pine (Pinus ponderosa) on a high hill 5.5 miles north (Road 530) of Creighton. We noticed several birds moving among the branches along the roadside and upon "spishing" for just a few seconds we attracted a female Cape May Warbler (Dendroica tigrina) and …

The Changing Status Of Sandhill Crane Breeding In The Eastern Rainwater Basin, Joel G. Jorgensen

Nebraska Bird Review

Prior to extirpation as a breeder before 1 900, the Sandhill Crane (Grus canadensis) formerly bred throughout Nebraska (Bruner et al. 1 904; Ducey 1988; Sharpe et al. 2001). During the 1990s, several summer observations of Sandhill Crane in the Eastern Rainwater Basin region of south-central Nebraska suggested the probability of breeding. In 1999, I discovered direct breeding evidence at Harvard Waterfowl Production Area, Clay County. This breeding record, along with another by different observers in the same county during the same season are the first modern breeding records for Nebraska. In this note, I describe my observations, …

Summer Field Report, June-July 2002, W. Ross Silcock

Nebraska Bird Review

The big news this summer was the drought which affected most of southern and western Nebraska. Conditions were particularly severe in the southern Panhandle and in the southwest. As one observer (DP) wryly noted: "The cool, cloudy weather in the sixties this morning was a welcome contrast to the stinkin' hot dirt blowing blast furnace in the low one hundreds that was in south central Nebraska Sunday afternoon [June 3]." Some comments from western Kansas by birder-rancher Scott Seltman are pertinent: "I think there's no question that because of the ongoing drought most farmers delayed their fieldwork this spring" perhaps …

Summer Field Report Last Page September 2002

Nebraska Bird Review

White-winged Crossbill: The remarkable winter influx persisted into the summer period, with one seen in Omaha- the last at the observer's feeders- on 1 June (NR), and a female identified as late as 20 June at a Bassett feeder where none had showed since 9 June (CH). These sightings signify record late spring dates (although there are a few isolated summer records); both locations had hosted significant wintering flocks.

2002 (12th) Report Of The Nou Records Committee, Joel G. Jorgensen

Nebraska Bird Review

The functions and methods of the NOU Records Committee are described in its bylaws (NOU Records Committee 1986). The committee's purpose is to provide a procedure for documenting unusual bird sightings and to establish a list of all documented birds for Nebraska. THE OFFICIAL LIST OF THE BIRDS OF NEBRASKA was first published in 1988 (NOU Records Committee 1988) and has been appended eleven times (Mollhoff 1989, Grenon 1990, Grenon 1991, Gubanyi 1996a, Gubanyi 1996b, Gubanyi 1996c, Brogie 1997, Brogie 1998, Brogie 1999).

Spring Field Report, March-May 2002, W. Ross Silcock

Nebraska Bird Review

A significant feature of this report is the fact that 94 observers provided data! E-mail has certainly provided a simple way to report sightings with ease, obviating for many the tedium of compiling a magnum opus four times a year (although the ultra-dedicated Harding and Randolph still filed their standard 40-pager!).

Interesting banding information was, provided for Red-eyed Vireo, Gray Catbird, and Pine Siskin by Ruth Green. The characteristics of the subspecies of Pine Siskin are not well-known anywhere, let alone in Nebraska.

Waterfowl and raptors had few significant sightings, although harriers were noted nesting at a couple of locations …

"Unnamed"

A yellow and black bird came to the apricot tree
this morning. I'd not seen it
before, in any of the yards here. I expect
to see such birds in the eastern woods,
not in these relatively arid tracts.

I couldn't identify it. Grosbeak? I had
no Guide, only gloomy thoughts
of no specific origin.

The bird stayed for no more than seconds.
It had a chunk of black on its throat,
like a thumbprint. Its wings never
were quiet.

Then it flew off, shrieking,
and the branch it was perched on joined
the swaying of the other …

Physiological Importance Of 1,25(Oh)2D3 Membrane-Initiated And Nuclear Actions In Chickens As A Function Of Growth, And Maturation In Male And Female Chickens, Birgitta Larsson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is well established that l,25(OH)₂D₃ is a major regulator of calcium homeostasis. The steroid exerts its effects on its target organs by two mechanisms, a slow mechanism mediated by nuclear vitamin D receptors (nVDR), and a rapid mechanism mediated by the l,25(OH)₂D₃ membrane-associated rapid response steroid binding protein (l,25D₃-MARRS bp). In this dissertation, the physiological relevance of membrane initiated steroid signaling was investigated by studying the correlation of age in male and female chickens with the magnitude of responses to l,25(OH)₂D₃ in duodena from 7-, 14-, 28-, and …

Rapid Actions Of 1,25-Dihydroxyvitamin D3 On Phosphate Uptake In Isolated Chick Intestinal Cells, Bin Zhao

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

1,25-dihydroxyvitamin D₃ [1,25(OH)₂D₃] has been shown to promote phosphate transport rapidly in the perfused duodenal loop, relative to controls, reaching treated/av basal at T = 40 min = 1.82 ± 0.42 and 1.11 ± 0.21, respectively.

By using isolated chick enterocytes, studies were undertaken to determine whether 1,25(OH)₂D₃ has a direct effect on isolated intestinal cells that is manifested by either enhanced uptake or extrusion of phosphate.

In time course studies, with 4- to 8-wk-old chicks, ³²P uptake in enterocytes at 10 min after addition of test substance was 0%, 130%, …

Winter Field Report, December 2001 To February 2002, W. Ross Silcock

Nebraska Bird Review

This winter was generally mild with most parts of the state at least somewhat dry. The most interesting avian phenomena were a major incursion of White-winged Crossbills and a warm-up in late January which resulted in several waterfowl species putting in very early appearances. Because of the latter, it was difficult to assess the status (wintering or migrant) of birds reported in late January to early February from major reservoirs and waterfowl concentration spots without some information on ice conditions. Thanks to Larry Einemann, I had detailed information about ice conditions at Branched Oak L, but I would appreciate a …

2001-2002 Christmas Bird Counts

A total of 12 counts are recorded on Tables Two and Three, three more than last year's effort. The Beaver Valley and Grand Island counts are run most years, but we sometimes miss receiving data from them. DeSotoBoyer is run every year but does not always get published here, perhaps because the tally is listed as an Iowa count according to the Audubon Society; however, the area covered is partially in Nebraska, and the participants are mostly Nebraska birders.

The counts reported a total of 138 species this year, up from 133 in 1999 and from 117 in 2000. Nearly …

Picturing Nature: Education, Ornithology And Photography In The Life Of Cordelia Stanwood: 1865-1958, Cynthia Watkins Richardson

Electronic Theses and Dissertations

The field of environmental history, with a few exceptions, has neglected gendered analysis; in addition, several women's histories have analyzed a few environmental issues, but disregard environmental scholarship. In the joining of women's and environmental history, this dissertation examines the life of one woman, Cordelia J. Stanwood of Ellsworth, Maine (1865-1958), to determine how a woman could use nature to transcend the social limits of domesticity in the early twentieth century. Research of her correspondence, published writing, photography and forty years of field notes reveals that like many other women, she took advantage of technology and evolving ideas about womanhood …

Organophosphate Toxicosis In Chickens: A Case Report, Robert Hubbard, Judith England, E. Dustan Clark

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Two cases of organophosphate toxicity were diagnosed at the University of Arkansas Poultry Science Department poultry research farm in the Spring of 2002. In both cases the birds were being treated with the organophosphate RaVap® for Northern Fowl Mites (Ornithonyssus sylvarium) infestations. A total of 61 birds died and 13 were treated successfully with atropine sulphate.
