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 …

Spring Field Report, March 2012 To May 2012, W. Ross Silcock
Nebraska Bird Review
This spring was a definite mixed bag ornithologically, in large part due to the mixed bag of weather conditions. Spring Beauty flowers bloomed 10–14 days early at Fontenelle Forest (RBa). Observers were decidedly mixed in their assessments of the season; veteran observers commenting on the passerine migration noted “poorest spring for passerines that I can recall” (LE) and “the sheer numbers of birds seemed ridiculously high for this early date of May 3rd” (JR). It should be noted that the 3 May date saw record counts of a few passerine species at Fontenelle Forest: 65 American Redstarts, 60 Blackpoll Warblers, …

Nebraska Bird Review
The Snowy Owl (Bubo scandiacus) is an Arctic breeder that regularly migrates to and winters in southern Canada and the northern United States (Parmalee 1992). The number of Snowy Owls moving south and the extent and timing of southward movements in any one year are believed to be dependent on interactions between populations of Snowy Owls and lemmings, the owls’ principal food resource (Parmalee 1992). Infrequently, relatively large numbers of Snowy Owls are observed in areas or regions where few are typically observed, and individuals are observed well south of the normal winter range. These occurrences are often …

Nest And Brood Site Selection And Survival Of Greater Prairie-Chickens In The Eastern Sandhills Of Nebraska, Lars Anderson
Nest And Brood Site Selection And Survival Of Greater Prairie-Chickens In The Eastern Sandhills Of Nebraska, Lars Anderson
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Greater prairie-chickens (Tympanuchus cupido pinnata) are a grassland bird species of conservation concern. Although greater prairie-chickens have declined over much of their range, the Nebraska Sandhills has the largest population in North America. However, the responses of nest and brood site selection and survival to vegetation characteristics are unknown. I studied prairie-chickens on private rangelands in Rock and Brown Counties from 2009-2011. I fitted 139 females with radio collars to locate nest and brood sites and to determine nest and brood survival rates. Females were trapped on leks during the breeding season and I monitored them throughout the …
Channel Width And Least Tern And Piping Plover Nesting Incidence On The Lower Platte River, Nebraska, Joel G. Jorgensen, Mary Bomberger Brown, Andrew J. Tyre
Channel Width And Least Tern And Piping Plover Nesting Incidence On The Lower Platte River, Nebraska, Joel G. Jorgensen, Mary Bomberger Brown, Andrew J. Tyre
Great Plains Research: A Journal of Natural and Social Sciences (through 2013)
Endangered interior least terns (Sternula antillarum athalassos) and threatened northern Great Plains piping plovers (Charadrius melodus) nest together on midstream sandbars in large rivers in the interior of North America. We investigated the relationship between river channel width and tern and plover nesting incidence on the lower Platte River, Nebraska, using a model-based logistic regression analysis. Multiple channel width measurements and a long-term nesting data set were used in the analysis. Nesting incidence was positively associated with increasing river channel width proximal to the nesting site. At a greater distance, up to 802 m away from …
Wetland Hydrodynamics And Long-Term Use Of Spring Migration Areas By Lesser Scaup In Eastern South Dakota, Sharon N. Kahara, Steven R. Chipps
Wetland Hydrodynamics And Long-Term Use Of Spring Migration Areas By Lesser Scaup In Eastern South Dakota, Sharon N. Kahara, Steven R. Chipps
Great Plains Research: A Journal of Natural and Social Sciences (through 2013)
Lesser scaup (Aythya affinis [Eyton]) populations remain below their long-term average despite improved habitat conditions along spring migration routes and at breeding grounds. Scaup are typically associated with large, semipermanent wetlands and exhibit regional preferences along migration routes. Identifying consistently used habitats for conservation and restoration is complicated by irregular wetland availability due to the dynamic climate. We modeled long-term wetland use by lesser scaup in eastern South Dakota based on surveys conducted during below-average (1987-1989) and above-average (1993-2002) water condition years. Wetland permanence, longitude, and physiographic region were all significant determinants of use (P < 0.01). Long-term use was best described by a quadratic equation including wetland surface area variability, an index of wetland hydrodynamics that is linked to productivity, biodiversity, and value to waterfowl. Contrary to previous findings, our study shows that over the long term, lesser scaup are more than twice as likely to use permanent wetlands as they are semipermanent wetlands. The northern region of South Dakota's Prairie Coteau, which holds the highest density of hydrologically dynamic permanent wetlands, should be considered an area of conservation concern for lesser scaup. The criteria we identified may be used to identify important lesser scaup habitats in other regions of the Prairie Pothole Region.

Fifteen counts, one more than last year, were held during the period, and a total of 139 species, 10 fewer than last year, were found. This was a count season of record totals for the state for a number of species. Factors contributing to this include the number of counts, the number of participants and the weather. More counts (15) were run than in any previous year, and several counts (Lake McConaughy in particular) had a much greater than average number of participants. The weather prior to the count period was mild, and most of the circles had unusually warm …

Report Of A Nesting Sora (Porzana Carolina), William M. Lemburg, Wayne J. Mollhoff
Nebraska Bird Review
During the summer of 2008, long-time NOU member and former NOU Treasurer William (Bill) Lemburg of Cairo, Howard Co., Nebraska, discovered the nest of a Sora (Porzana carolina). On 29 July 2008, while using a small flat-bottomed boat to gather duckweed (Spirodela polyrhiza) on a small pond near his bird pens to feed the exotic waterfowl he raises, he noted a pair of Sora walking about, foraging atop the dense growth of duckweed. The pair ignored his presence even though, as he later discovered, he was within 10 feet of their nest. The following evening, 30 …

Winter Field Report, December 2011 To February 2012, W. Ross Silcock
Nebraska Bird Review
The most obvious feature of this winter’s avian movements was the number of Snowy Owls, unprecedented in living memory, that invaded the state. A tally maintained by Joel Jorgensen and Lauren Dinan of Nebraska Game and Parks indicated that over 200 snowies were found in the state, and most were documented. Not as popular with the public, but perhaps of greater scientific interest were the mid-winter reports of species normally rare at this time of year. Most notable in this respect were waterfowl, grebes, cranes, and sparrows. A read-through of these species suggests the very mild winter experienced over most …

Mid-Contract Management Of Conservation Reserve Program Grasslands Provides Benefits For Ring-Necked Pheasant Nest And Brood Survival, Ty W. Matthews, J. Scott Taylor, Larkin A. Powell
School of Natural Resources: Faculty Publications
Conservation Reserve Program (CRP) fields may provide good habitat for nesting and brood-rearing ring-necked pheasants (Phasianus colchicus) during early stages of succession. But, the success of hens in early successional CRP, relative to late successional CRP and other grassland habitats, has yet to be evaluated. The reproductive period is especially critical for populations of pheasants, and CRP’s benefits to hens and chicks may decrease as fields age because of loss of vegetative diversity, decrease in vegetation density, and accumulation of residual litter. During 2005– 2006, we evaluated spatial and temporal variation in nest and brood survival for radio-marked hen pheasants …

Patterns Of Incubation Behavior In Northern Bobwhites (Colinus Virginianus), Jonathan S. Burnam, Gretchen Turner, Susan Ellis-Felege, William E. Palmer, D. Clay Sisson, John P. Carroll
School of Natural Resources: Faculty Publications
Patterns of incubation and nesting behavior for many species of birds, especially those with cryptic nests, have been difficult to obtain due to logistical and technological limitations. As a result, little is known about the daily attendance rhythms and behavioral patterns of many species, including the Northern Bobwhite (Colinus virginianus), despite this species being one of the most studied birds in the world. Incubation represents parental investment in offspring, and a multitude of factors may affect investment behaviors, including reproductive ecology, sex and age of parent, habitat quality, clutch age, and timing in the nesting season. Most Northern Bobwhite nests …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
The quality and size of nestling food of the Desert Wheatear Oenanthe deserti ssp. atrogularis were investigated in the spring of 2001 in the Dzungarian Gobi in Mongolia. Data are based on observations of nine pairs. Nestling food consisted of several taxa caught on the ground and in the air. Diptera, Coleoptera larvae, and Hymenoptera were the most frequent prey, that is, they contributed 17 to 30% of all food items each. The food composition changed with nestling age and season.
Food item size decreased with date. A higher proportion of multiple prey loadings were brought to nestlings in the …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
Introduction
A common inhabitant of East Siberian larch forests, the Siberian or black-billed capercaillie (Tetrao urogalloides) ranges south to the limits of the boreal forests in the northern Mongolian mountains and east to the very coast of the Asian continent (KLAUS et al. 1989). Tetrao urogalloides MIDDENDORF (1851) has priority over T. parvirostris BONAPARTE (1856). Therefore, we prefer the T. urogalloides.
The subspecies T.u. stegmanni was first described on the basis of morphological differences by POTAPOV (1985) using specimens collected during Russian expeditions by KOZLOVA (1930). This description was based on 18 males in the collection at …

What-where-when (WWW) memory during cache recovery was investigated in six Clark’s nutcrackers. During caching, both red- and blue-colored pine seeds were cached by the birds in holes filled with sand. Either a short (3 day) retention interval (RI) or a long (9 day) RI was followed by a recovery session during which caches were replaced with either a single seed or wooden bead depending upon the color of the cache and length of the retention interval. Knowledge of what was in the cache (seed or bead), where it was located, and when the cache had been made (3 or 9 …

School of Natural Resources: Faculty Publications
The variation in breeding colony size seen in populations of most colonial birds may reflect heritable choices made by individuals that are phenotypically specialized for particular social environments. Although a few studies have reported evidence for genetically based choice of group sizes in birds, we know relatively little about the extent to which animals potentially rely on experience versus innate preferences in deciding how many conspecifics to settle with at different times of their lives. We conducted a cross-fostering experiment in 1997–1998 on cliff swallows, Petrochelidon pyrrhonota, in southwestern Nebraska, USA, in which some individuals were reared in colonies …
