Stomach Content Analysis Of Recent Snowy Owl (Bubo Scandiacus) Specimens From Nebraska, Rachel L. Valenziano, Thomas E. Labedz

Nebraska Bird Review

The Snowy Owl (Bubo scandiacus) is a circumpolar bird of prey that breeds in extreme northern latitudes, including Canadian and Alaskan tundra. During winter months, some immature and non-breeding birds disperse south. North American birds may travel to southern Canada and northern parts of the United States, and in some extreme cases as far south as Oklahoma and Texas (Parmelee 1992). Although not fully understood, these irruptive events may be caused by the abundance of prey in northern Canada and Alaska (Parmelee 1992).

Prey typical of Snowy Owls are small mammals (e.g., lemmings and hares) of their home range and …

Across-Year Social Stability Shapes Network Structure In Wintering Migrant Sparrows, Daizaburo Shizuka, Alexis S. Chaine, Jennifer Anderson, Oscar Johnson, Inger Marie Laursen, Bruce E. Lyon

School of Biological Sciences: Faculty Publications

Migratory birds often form flocks on their wintering grounds, but important details of social structure such as the patterns of association between individuals are virtually unknown. We analysed networks of co-membership in short-term flocks for wintering golden-crowned sparrows (Zonotrichia atricapilla) across three years and discovered social complexity unsuspected for migratory songbirds. The population was consistently clustered into distinct social communities within a relatively small area (~ 7 ha). Birds returned to the same community across years, with mortality and recruitment leading to some degree of turnover in membership. These spatiotemporal patterns were explained by the combination of space …

Assessing Landscape Constraints On Species Abundance: Does The Neighborhood Limit Species Response To Local Habitat Conservation Programs?, Christopher F. Jorgensen, Larkin A. Powell, Jeffrey J. Lusk, Andrew A. Bishop, Joseph J. Fontaine

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Landscapes in agricultural systems continue to undergo significant change, and the loss of biodiversity is an ever-increasing threat. Although habitat restoration is beneficial, management actions do not always result in the desired outcome. Managers must understand why management actions fail; yet, past studies have focused on assessing habitat attributes at a single spatial scale, and often fail to consider the importance of ecological mechanisms that act across spatial scales. We located survey sites across southern Nebraska, USA and conducted point counts to estimate Ring-necked Pheasant abundance, an economically important species to the region, while simultaneously quantifying landscape effects using a …

Double-Crested Cormorant And American White Pelican Abundance At Sandhills Lakes During Fall Migration, Lauren R. Dinan, Joel G. Jorgensen

Nebraska Bird Review

Double-crested Cormorants (DCCO, Phalacrocorax auritus) and American White Pelicans (AWPE, Pelecanus erythrorhynchos) are migratory piscivorous birds that breed in North America. Both species are abundant spring and fall migrants in Nebraska. DCCOs are also common, albeit local, breeders in northwestern Nebraska (Sharpe et al. 2001 ). DCCO and AWPE numbers have increased throughout their range in recent decades (U.S. Fish and Wildlife Service [USFWS] 2003, Sauer et al. 2013). Both species, but primarily DCCOs, have become increasingly controversial because of increased numbers and also because their principal food source is fish, a resource humans value. Concentrations of DCCOs, and to …

2014 Nou/Iou Joint Meeting In Bellevue, Clem Klaphake

Nebraska Bird Review

The May 16–18 combined meeting of the Nebraska Ornithologists' Union and the Iowa Ornithologists' Union at Fontenelle Forest Nature Center in Bellevue, Nebraska, was a gigantic success. Over 160 birders from Nebraska, Iowa, and 6 other states attended the 3 day event. Everyone I talked to, from novice to expert, was more than delighted with all of the activities scheduled for this event.

Our Friday evening speaker, Ty Smedes, had some wonderful photos, especially of warblers, and I heard nothing but positive comments about his program from the attendees. On Saturday afternoon Jerry Toll talked about his experiences banding Red-tailed …

Spring Field Report, March 2014 To May 2014, W. Ross Silcock

Nebraska Bird Review

This spring period was generally uneventful for most species groups, but there were two major influxes in the east that were likely unprecedented in the memories of most Nebraska ornithologists. First was a major influx of gulls of 10 species at Carter Lake and N.P. Dodge Park in Omaha, including good numbers of California and Thayer's Gulls, as well as Iceland, and most surprisingly, a Glaucous-winged Gull. A bit later in the season was a strong influx of the rarer migrant warblers, such as Golden-winged, Blue-winged, Hooded, Cape May, Bay-breasted, and Black-throated Blue. For spice there was a Worm-eating Warbler …

What Are Blue Ross's Geese?, Paul A. Johnsgard

Nebraska Bird Review

The existence of blue morph ("phase") Ross's Geese (Chen rossii) was first well documented by McLandress & McLandress (1979). They reported on several blue-morph birds seen and collected in California and Canada that morphologically appeared to be pure Ross's Geese and on others with intermediate traits that appeared to be hybrids with Lesser Snow Geese (Chen caerulescens caerulescens). They also noted that in the California wintering grounds counts held during 1976–77 there were only 3 blue morphs (0.008 percent) among the 38,825 Ross's Geese counted. At that time, only 0.02 percent of the Lesser Snow Geese …

New Species Records And Changes In Abundance Of Waterfowl In Northwest Greenland, K. K. Burnham, D. R. Sinnett, J. A. Johnson, J. L. Burnham, J. A. Baroch

United States Department of Agriculture Wildlife Services: Staff Publications

Breeding populations of Nearctic and Palearctic waterfowl have undergone significant changes in abundance and distribution over the past 50 years. The Avanersuaq District in northwest Greenland is home to an assemblage of waterfowl from both geographic areas; however, minimal historic or current information is available on species abundance. In 2008 and 2009, we conducted field surveys in Greenland from 76.00_ to 77.35_N for breeding and non-breeding waterfowl and have collected anecdotal field notes of avian observations over a 20-year period (1993–2012). During these periods, we documented the first observation of a Ross’s goose (Chen rossii) and the first confirmed breeding …

Effects Of Conventional And Alternative Curing Methods On Processed Turkey Quality Traits, Amy Lynn Redfield

Department of Animal Science: Dissertations, Theses, and Student Research

This study compared physicochemical and sensory qualities of deli-style turkey breast produced pre-converted celery juice powder (CP; for alternative curing) or sodium nitrite (SN; for conventional curing). Formulas were designed to include 0, 50, 100, 150, and 200 ppm ingoing sodium nitrite or the equivalent from CP or SN, and 3 replicates of products were manufactured. Turkey and curing brines were tumbled, stuffed, and cooked to an internal temperature of 73.9^oC. Products were stabilized and sliced into 12 mm slices (physicochemical trait analysis) and 2 mm slices (sensory trait analysis). Physicochemical traits measured only on d 0 were …

The Effects Of Feed Additives, Housing Systems, And Stress On Salmonella Shedding In Single Comb White And Brown Laying Hens, Dana L. Hahn

Department of Animal Science: Dissertations, Theses, and Student Research

A series of studies were conducted examining feed additives, housing systems and stress on Salmonella shedding. Alternative feed additives such as prebiotics, probiotics and essential oils have been shown to reduce pathogenic bacteria colonization. Furthermore, stressors such as movement have been shown to increase Salmonella shedding. The goal of the studies was to examine if alternative ingredients reduce Salmonella shedding in alternative housing systems and through movement stress. Study 1 examined cage and cage-free housing with mannan oligosaccharide (MOS) supplementation. Treatments were arranged in a 2x2 factorial design: cage or cage free; MOS (0% or 0.08%). There was no effect …

Fear Effects On Pheasant Reproductive Ecology And A Curriculum To Teach Wildlife Habitat Selection, Jessica Laskowski

School of Natural Resources: Dissertations, Theses, and Student Research

Predation risk is an important source of selection that shapes prey density, distribution and abundance. The immediate impacts of predator consumption on prey populations are widespread and well-studied, and a growing body of research demonstrates immediate impacts of predator-induced fear (independent of prey mortality) on prey behavior, physiology and life-history expression. However, predation risk is often seasonally variable and while it is clear that consumption effects often carry over to influence prey population demography for years after predators have disappeared, the temporal carry-over effects of fear on prey populations remain largely unexplored. We assessed effects of fall hunting activity by …

Winter Field Report, December 2013 To February 2014, W. Ross Silcock

Nebraska Bird Review

This was a low-key winter season in terms of reportable phenomena of any significance, although three species provided food for thought: high numbers of Rough-legged Hawks, the possibility of breeding Northern Saw-whet Owls in the cedar canyons of Lincoln Co, and the possible impending demise of Black-billed Magpie over most of the state. Also noteworthy is the continuing increase in midwinter reports of a wide range of species that previously have accounted for very few such records. Notable in this respect are waterfowl, mimids, non-oriole icterids, and sparrows; a Say's Phoebe in December was the most surprising record in this …

Breeding Season Observations Of Sandhill Cranes On The Niobrara River In Nebraska, Mark Czaplewski, Jim Jenniges, Mark Peyton

Nebraska Bird Review

Central Platte Natural Resources District (CPNRD), Nebraska Public Power District (NPPD), and the Central Nebraska Public Power and Irrigation District (Central) have been involved in the monitoring of Interior Least Terns (Sternula antillarum athalassos) and Piping Plovers (Charadrius melodus) along portions on the lower Niobrara River in northeast Nebraska since 2005. On two occasions, we observed a pair of adult Sandhill Cranes (Grus canadensis) during the breeding season.

A pair of adult cranes was observed on June 8, 2011, on the Niobrara River approximately 7.8 km below the U.S. Route 137 bridge in Holt …

2013 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Fifteen counts were held during the 2013–2014 season. Following a cold snap in early December, the weather was seasonable and mostly dry, but with very limited open water in most circles. An example of the consequences of this can be seen in the Branched Oak–Seward count tally. Although this count has a history of being very productive for water-related birds in most years, only 3 species were found this year: Canada Goose (16), Mallard (2) and Belted Kingfisher (1). The total species count in all the counts was 135, four less than the past two years and historically ranking sixth …

Environmental Salmonella In Agricultural Fair Poultry Exhibits In Colorado, K. L. Pabilonia, K. J. Cadmus, T. M. Lingus, D. S. Bolte, M. M. Russell, D. C. Van Metre, M. M. Erdman

United States Department of Agriculture Wildlife Services: Staff Publications

Salmonella enterica is a common zoonotic pathogen in humans. Transmission typically occurs through consumption of contaminated food products or contact with infected animals, including poultry or their environment. The objective of this study was to estimate the frequency of Salmonella contamination in the environment in poultry exhibits at agricultural fairs. Samples were collected from cages, feed, floors and tables in the exhibit and cultured for Salmonella. At least one environmental sample was positive for Salmonella in 10 of 11 fairs (91%), and Salmonella was isolated from 28 of 55 environmental samples (50.9%). Eleven different serotypes were detected. Results of …

First Documented Record Of Hooded Oriole (Icterus Cucullatus) In Nebraska, Joseph Gubanyi

Nebraska Bird Review

During May 2013 a very cooperative Hooded Oriole (Icterus cucullatus) provided lots of excitement for Nebraska birders, becoming the first documented record for the species in Nebraska. The bird was first observed 25 May 2013 by Susie and Bill Daro at their residence in Garrison (Butler County). The Daros have several oriole feeders, and Baltimore and Orchard Orioles are common visitors. On the morning of May 25 they noted an unusual oriole visiting their feeders and, after checking the National Geographic Field Guide to the Birds of North America, concluded it was a Hooded Oriole. They found …

Hayden, Tristram, And A Pigeon From “Nebraska”, Rick Wright

Nebraska Bird Review

A passenger pigeon skin in the World Museum in Liverpool, England, was collected during an expedition to Nebraska and Dakota led by Gouverneur K. Warren between 1855 and 1857 and later cataloged by geologist and naturalist Ferdinand V. Hayden. For a time it was in the collection of Henry Baker Tristram, a famous naturalist and a founder of the British Ornithologists’ Union. Passenger pigeons were once “quite abundant” along the Missouri River.

Fall Field Report, August–November 2013, W. Ross Silcock

Nebraska Bird Review

In most ways, this was a routine fall season. Most interesting from an ongoing point of view were quite a large number of sightings of passerines at rather late dates, notably Empidonax flycatchers, wood warblers, native sparrows, tanagers, towhees, grosbeaks, and buntings. A similar phenomenon was noted among a few cold-sensitive non-passerines, such as Black and Common Terns.

One of the more significant ongoing trends is the proliferation of western and southern hummingbirds and the alteration of traditional migration and summer ranges; no fewer than 6 species were found. Calliope and Rufous Hummingbirds were seemingly more numerous in the east …
