Winter Microhabitat Foraging Preferences Of Sympatric Boreal And Black-Capped Chickadees In Michigan's Upper Peninsula, Alec R. Lindsay Ph. D., Zach G. Gayk
Winter Microhabitat Foraging Preferences Of Sympatric Boreal And Black-Capped Chickadees In Michigan's Upper Peninsula, Alec R. Lindsay Ph. D., Zach G. Gayk
Faculty Works
We examined differences in microhab- itat use between Boreal (Poecile hudsonicus) and Black- capped chickadees (P. atricapillus) where they co-occur near Marquette, Michigan, USA. Twenty-four Boreal and 37 Black-capped chickadees were followed during 60 hrs of field observation. Boreal Chickadees foraged only in three conifer species, 76% of which were black spruce (Picea mariana), while Black-capped Chickadees foraged widely across six coniferous and three deciduous tree species. Analysis of foraging data categorized by zones within conifer trees indicated high niche overlap (0.676) between Boreal and Black-capped chickadees across all foraging zones. Individual comparisons on a zone-by-zone basis revealed a significant …

Cues Used By The Black Fly, Simulium Annulus, For Attraction To The Common Loon (Gavia Immer), Meggin L. Weinandt, Michael W. Meyer, R. Mac Strand, Alec R. Lindsay Ph. D.
Faculty Works
The parasitic relationship between a black fly, Simulium annulus, and the common loon (Gavia immer) has been considered one of the most exclusive relationships between any host species and a black fly species. To test the host specificity of this blood-feeding insect, we made a series of bird decoy presentations to black flies on loon-inhabited lakes in northern Wisconsin, U.S.A. To examine the importance of chemical and visual cues for black fly detection of and attraction to hosts, we made decoy presentations with and without chemical cues. Flies attracted to the decoys were collected, identified to species, and quantified. Results …

Fall Field Report, August–November 2012, W. Ross Silcock
Nebraska Bird Review
Some of you may be curious about the sources of sightings I use to compile these reports. The primary sources are reports posted to NEBirds, the Nebraska Listserv, along with the full reports (early and late dates, peak counts for all species) sent by a few faithful reporters around the state. The latter reports are very useful overviews of movements in the reporters' regions. Lately, thanks to a suggestion by Clem Klaphake, I have been receiving the eBird daily rarity report for Nebraska which I find to be an excellent check against reports posted to NEBirds, while providing a few …

Notes On A Greater Sage-Grouse Record By Levi L. Mohler, Mark A. Brogie
Notes On A Greater Sage-Grouse Record By Levi L. Mohler, Mark A. Brogie
Nebraska Bird Review
In Nebraska, Greater Sage-Grouse has been considered an uncommon casual winter visitor in the extreme northwest (Sharpe et al. 2001). This species may now be extirpated in Nebraska due to habitat loss. There have been no known Nebraska observations of Greater Sage-Grouse in the last 25 years. The only documented record accepted by the NOURC of Greater Sage-Grouse in Nebraska (Accession #243) is a description of an adult male in September 1987 in extreme northwest Sioux County by Douglas Kapke (Grenon AG. 1990).
In 2002 Wayne Mollhoff received the following record from Levi L. Mohler and submitted it to the …

Winter Ecology Of Sandhill Cranes (Grus Canandensis) In Northern Mexico, Ingrid Barcelo
Winter Ecology Of Sandhill Cranes (Grus Canandensis) In Northern Mexico, Ingrid Barcelo
School of Natural Resources: Dissertations, Theses, and Student Research
Sandhill Cranes (Grus canadensis) are a widespread species in North America and one of the most studied cranes in the world. However, most of the research has focused on the breeding grounds of Canada and Alaska and the staging grounds of Nebraska. Although an important proportion of the Mid-continent Population of Sandhill Cranes winters in northern Mexico, little information exists on distribution, status, and ecology of the species in Mexico. The goal of this dissertation was to provide new information on Sandhill Crane winter ecology from a regional perspective to better understand population trends. I examined the physiological …
Site Selection By Migratory Shorebirds In Oregon Estuaries Over Broad And Fine Spatial Scales, Aileen Kilpatrick Miller
Site Selection By Migratory Shorebirds In Oregon Estuaries Over Broad And Fine Spatial Scales, Aileen Kilpatrick Miller
Dissertations and Theses
Many migratory shorebirds rely on estuaries as stop-over sites to refuel during migration, and the loss of stop-over sites is a primary threat to shorebird populations on the West Coast of the United States (e.g. Calidris alpina pacifica, C. mauri). Conservation and research has focused on the largest of these sites; however, smaller estuaries also host thousands of migratory shorebirds. Furthermore, the reasons for site selection are largely unknown. Estuarine inter-tidal microhabitats are non-uniform and both abiotic and biotic factors may serve as predictors of whether an abundance of shorebirds will use a site. I investigated shorebird site selection on …
Stopover Decisions Of Migratory Shorebirds: An Assessment Of Habitat Use, Food Availability, Behavior And Phenology, Ryan Stutzman
Stopover Decisions Of Migratory Shorebirds: An Assessment Of Habitat Use, Food Availability, Behavior And Phenology, Ryan Stutzman
School of Natural Resources: Dissertations, Theses, and Student Research
Habitat loss and alteration from land use change, species invasion, and more recently, climate change has reduced biodiversity and ecosystem function worldwide. Habitat decisions have important implications to individual fitness as well as population dynamics and community structure. Resource limitation, predation, competition, and unfavorable abiotic conditions all have the potential to influence survival and future reproductive potential. Understanding how changes to ecosystem structure and function impact species and populations of conservation concern is essential for conservation delivery to be effective. Similar to many migratory species, shorebird populations are declining worldwide and declines may be related to the loss of important …

Ring-Necked Pheasant Hens Select Managed Conservation Reserve Program Grasslands For Nesting And Brood-Rearing, Ty W. Matthews, J. Scott Taylor, Larkin A. Powell
School of Natural Resources: Faculty Publications
The Conservation Reserve Program (CRP) has provided critical wildlife habitat for many species since 1985. However, the quality of this habitat for early successional species, such as ring-necked pheasant (Phasianus colchicus), may decrease with field age. Late successional grasslands may lack valuable vegetative and structural diversity needed by pheasants, especially during nesting and brood-rearing stages. Since 2004, the United States Department of Agriculture has required new CRP contracts to include plans for mid-contract management, which could include discing and interseeding. The benefits of such practices have not been assessed, and continuation of current policy could be affected by the lack …

Mccown’S Longspur (Rhynchophanes Mccownii): Species Conservation Assessment, Melissa J. Panella
Mccown’S Longspur (Rhynchophanes Mccownii): Species Conservation Assessment, Melissa J. Panella
Nebraska Game and Parks Commission: Publications
The primary goal in development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the McCown’s Longspur (Rhynchophanes mccownii) as a Tier I at-risk species. Some general management recommendations are made here regarding the McCown’s Longspur (MCLO); however, conservation practitioners will need to use professional judgment to make specific management decisions based on objectives, location, and a multitude of variables. This resource was designed to share available knowledge of MCLO that will aid in the decision-making …
Morph Matters: Aggression Bias In A Polymorphic Sparrow, Brent M. Horton, Mark E. Hauber, Donna L. Maney
Morph Matters: Aggression Bias In A Polymorphic Sparrow, Brent M. Horton, Mark E. Hauber, Donna L. Maney
Publications and Research
In species with discrete morphs exhibiting alternative behavioral strategies, individuals may vary their aggressive behavior in competitive encounters according to the phenotype of their opponent. Such aggression bias has been documented in multiple polymorphic species evolving under negative frequency-dependent selection, but it has not been well-studied under other selection regimes. We investigated this phenomenon in white-throated sparrows (Zonotrichia albicollis), a passerine with plumage polychromatism maintained by disassortative mating. The two distinct color morphs differ with respect to reproductive strategy in that white-striped birds invest more in territorial aggression than tan-striped birds. Whether territorial aggression in this species is biased according …
Review Of Birds Of Southwestern Nebraska: An Annotated Check-List Of Species In The North And South Platte River Valleys And At Lake Mcconaughy. By Mary Bomberger Brown, Stephen J. Dinsmore, And Charles R. Brown., Wayne Mollhoff
Great Plains Research: A Journal of Natural and Social Sciences (through 2013)
Opening with a map of the region under study, Birds of Southwestern Nebraska proceeds, in its introduction, to a summary of the presettlement landscape and a description of the large-scale habitat changes occurring since then, along with avian responses to those changes. While crediting previous avian studies in southwestern Nebraska, often not readily available to the public, the authors note this area initially received little attention from ornithologists, who tended to focus on other biologically unique parts of the state, such as the Sandhills, forests, and Pine Ridge. The body of the book consists of a list of species reported …
Review Of Conspecific Attraction And Area Sensitivity Of Grassland Birds, David R.W. Bruinsma, Nicola Koper
Review Of Conspecific Attraction And Area Sensitivity Of Grassland Birds, David R.W. Bruinsma, Nicola Koper
Great Plains Research: A Journal of Natural and Social Sciences (through 2013)
Many species of grassland birds are area sensitive, which may exacerbate the ecological effects of the extensive loss and fragmentation of grasslands that has taken place across the northern Great Plains. However, the reasons for this area sensitivity are unclear, as vegetation structure, matrix composition, and restriction of movements among patches do not seem to provide viable explanations for species native to grasslands. Con specific attraction, whereby species are behaviorally stimulated to select habitat or establish territories near individuals of the same species, may help explain this area sensitivity. We review and discuss theoretical and empirical research on avian conspecific …

This report provides results and comparisons of two Monitoring Avian Productivity & Survivorship (MAPS) stations operated in central eastern Nebraska. MAPS is a multinational research project managed by the Institute for Bird Populations (IBP) in Point Reyes, CA (http://www.birdpop.org/maps.htm). The project is designed to monitor the population trends and breeding success of breeding birds in North America. Each year, more than 500 participants throughout North America collect data (via the process of bird banding) according to strict protocols and then submit their data to IBP for analysis and interpretation. MAPS began in 1989, and similar studies have subsequently begun on …

Summer Field Report, June–July 2012, W. Ross Silcock
Nebraska Bird Review
This summer most of Nebraska was very dry, with "Exceptional Drought" everywhere but the extreme southeast, according to the United States Department of Agriculture's Drought Monitor (http://droughtmonitor.unl.edu). Although no really striking effects were noted, several bits of evidence attested to the difficult conditions. Wetlands dried up in most cases in the Rainwater Basin, reflected by a lack of Great Egrets, Cattle Egrets, and Black-necked Stilts, and there were no stilt nests reported. However, Yellow-crowned Night-Herons surprisingly staged an incursion, perhaps continuing to disperse northward from their customary haunts in the almost equally dry Kansas and Oklahoma. Cliff Swallow colonies may …

Foraging Ecology Of Fall-Migrating Shorebirds In The Illinois River Valley, Randolph V. Smith, Joshua Stafford, Aaron P. Yetter, Michelle M. Horath, Christopher S. Hine, Jeffery P. Hover
Natural Resource Management Faculty Publications
Populations of many shorebird species appear to be declining in North America, and food resources at stopover habitats may limit migratory bird populations. We investigated body condition of, and foraging habitat and diet selection by 4 species of shorebirds in the central Illinois River valley during fall migrations 2007 and 2008 (Killdeer [Charadrius vociferus], Least Sandpiper [Calidris minutilla], Pectoral Sandpiper [Calidris melanotos], and Lesser Yellowlegs [Tringa flavipes]). All species except Killdeer were in good to excellent condition, based on size-corrected body mass and fat scores. Shorebird diets were dominated by invertebrate taxa from Orders Diptera and Coleoptera. Additionally, Isopoda, Hemiptera, …
Birds In Residential Metropolitan New Orleans Neighborhoods And Their Relationships To The Batture And Yard Vegetation, Ruth A. Guymon
Birds In Residential Metropolitan New Orleans Neighborhoods And Their Relationships To The Batture And Yard Vegetation, Ruth A. Guymon
LSU New Orleans Theses and Dissertations
Metropolitan New Orleans Neighborhoods were surveyed in order to determine how bird populations responded to distance from the batture, percent canopy cover, stem counts, and understory vegetation. Surveys were conducted in the spring and summer of 2010. It was found that batture birds, urban birds, and pooled birds all had greater species richness and abundance in the spring in areas with more canopy cover, higher stem counts, more understory vegetation, and distances closer to the batture. In the summer, batture birds had greater richness and abundance in areas with more canopy cover, higher stem counts, and more understory cover. This …

Evaluation Of The Effects Of September Hunting Seasons On Canada Geese In Nebraska, Scott R. Groepper, Mark P. Vrtiska, Larkin A. Powell, Scott E. Hygnstrom
Evaluation Of The Effects Of September Hunting Seasons On Canada Geese In Nebraska, Scott R. Groepper, Mark P. Vrtiska, Larkin A. Powell, Scott E. Hygnstrom
School of Natural Resources: Faculty Publications
Populations of temperate-nesting Canada geese (Branta canadensis) have increased in Nebraska, USA, resulting in an increased number of nuisance and damage complaints. September hunting seasons were initiated in southeastern Nebraska in 2004 to reduce populations of Canada geese. We analyzed band recoveries from Canada geese banded in southeastern Nebraska during their hatch-year (HY) or after-hatch-year (AHY) to determine whether September hunting seasons affected survival, harvest, and recovery rates. Survival analyses revealed that HY geese had higher survival than AHY geese (SAHY = 0.696, 95% CI = 0.679–0.713; SHY = 0.896, 95% CI = 0.786–0.953) and September seasons did …

Biology Faculty Publications and Presentations
We explored the breeding biology of the Northern Pygmy-Owl (Glaucidium gnoma) from 2007 to 2009 in a forested reserve in Portland, Oregon. Large body size is often assumed to give animals reproductive advantages, and we tested whether body size affected timing of breeding and examined variation in diet, breeding date, clutch size, and reproductive success to explore whether the presumed benefits of large body size are evident in this species. The average size of 13 clutches was 5.8, and nest success was high (92%); 22 successful nests fledged an average of 5.2 young. Dates of first laying varied …

Nutritional Content of Rhinoceros Auklet Bill Loads
Dustin E Taylor
Abstract
An adult Rhinoceros Auklet (Cerorhinca monocerata) can only catch and carry a limited amount of prey to their nestlings after a foraging trip. The auklets therefore must maximize their efficiency by bringing back the most proportionally nutritious prey items to their nestlings. The prey carried back to the nesting sites (known as a ‘bill load’) can contain whole fish, as well as parts, most commonly fish heads. This study is aimed to determine whether returning with just heads to the nestlings was proportionally more nutritious than bringing …

Experimental Evidence For The Interplay Of Exogenous And Endogenous Factors On The Movement Ecology Of A Migrating Songbird, Emily B. Cohen, Frank R. Moore, Richard A. Fischer
Faculty Publications
Movement patterns during songbird migration remain poorly understood despite their expected fitness consequences in terms of survival, energetic condition and timing of migration that will carry over to subsequent phases of the annual cycle. We took an experimental approach to test hypotheses regarding the influence of habitat, energetic condition, time of season and sex on the hour-by-hour, local movement decisions of a songbird during spring stopover. To simulate arrival of nocturnal migrants at unfamiliar stopover sites, we translocated and continuously tracked migratory red-eyed vireos (Vireo olivaceus) throughout spring stopover with and without energetic reserves that were released in two replicates …
