Fall Field Report, August - November 2017, W. Ross Silcock Dec 2017

Fall Field Report, August - November 2017, W. Ross Silcock

Nebraska Bird Review

This fall season will be remembered as the fall with the mega-rarities. There were five, one of which, Pacific Wren, is a first Nebraska record. Based on occurrence dates, Hurricane Irma appears to have influenced the appearance of two of the megas, Black Vulture and Magnificent Frigatebird, neither of which provided opportunities for observers to view them, but both well-documented with photographs. There were an extraordinary TWO sightings of Harris’s Hawk, which together with the presence as of this writing (December 19) of one in northeast Kansas and a view of the species map in eBird strongly suggest a single …

Ogallala Fall Field Days, Sept. 15 - 17, 2017, Janis Paseka

Nebraska Bird Review

The 2017 NOU Fall Field Days took place in and around Ogallala on Sept. 15 - 17 with 55 in attendance. The weather on Friday was hot and windy, making finding birds a challenge. Overnight a cold front came through causing birders to shiver on Saturday and Sunday mornings, but the payoff was easier birding and some interesting species. Field trips were led by William Flack, Clem Klaphake, Wayne Mollhoff, Don Paseka, Ross Silcock and T. J. Walker. Locations included Cedar Point Biological Station, Lake Ogallala SRA, various beaches along the shore of Lake McConaughy SRA, Ash Hollow State Historical …


Effectiveness Of Chain Link Turtle Fence And Culverts In Reducing Turtle Mortality And Providing Connectivity Along U.S. Hwy 83, Valentine National Wildlife Refuge, Nebraska, Usa, Marcel P. Huijser, Kari E. Gunson, Elizabeth R. Fairbank Dec 2017

Effectiveness Of Chain Link Turtle Fence And Culverts In Reducing Turtle Mortality And Providing Connectivity Along U.S. Hwy 83, Valentine National Wildlife Refuge, Nebraska, Usa, Marcel P. Huijser, Kari E. Gunson, Elizabeth R. Fairbank

Nebraska Department of Transportation: Research Reports

We evaluated the effectiveness of existing turtle fences through collecting and analyzing turtle mortality data along U.S. Hwy 83, in and around Valentine National Wildlife Refuge, Nebraska, USA. We also investigated the level of connectivity for turtles provided through the culverts that were originally designed to pass water through a capture-mark-recapture experiment. While fenced valley sections had 33.1% fewer turtle observations than unfenced valley sections, the difference was not significant. However, we think that the effectiveness of the fence can be improved through fence repairs, other modifications of the fences, vegetation maintenance, and extending the length of the fences. Four …


The North American Quails, Partridges, And Pheasants, Paul A. Johnsgard Oct 2017

The North American Quails, Partridges, And Pheasants, Paul A. Johnsgard

Zea E-Books Collection

This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel’s, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly …


European Starlings, H. Jeffrey Homan, Ron J. Johnson, James R. Thiele, George M. Linz Sep 2017

European Starlings, H. Jeffrey Homan, Ron J. Johnson, James R. Thiele, George M. Linz

Wildlife Damage Management Technical Series

European starlings (Sturnus vulgaris, Figure 1) are an invasive species in the United States. The first recorded release of the birds was in 1890 in New York City’s Central Park. Because starlings easily adapt to a variety of habitats, nest sites and food sources, the birds spread quickly across the country. Today, there are about 150 million starlings in North America. Conflicts between people and starlings occur mostly in agricultural settings. Conflicts can occur during winter in urban and suburban environments, especially in business districts.

Starlings damage apples, blueberries, cherries, figs, grapes, peaches, and strawberries. Besides causing direct losses from …

Summer Field Report, June - July 2017, W. Ross Silcock

Nebraska Bird Review

Changes in breeding ranges and numbers of Nebraska breeding birds are the primary focus of a Summer Seasonal Report. Every year there are changes to be noted; this year is no exception. Although most of the phenomena listed below are examples of dispersing individuals without breeding evidence, these often indicate breeding range expansion. White-winged Doves are becoming numerous in southern and western Nebraska, although breeding in far eastern Nebraska was only the 5th report for the state. Chuckwill’s- widow continues to creep westward in the south; the westernmost report to date was of one that crossed the 100-mile gap from …


Diet And Habitat Analysis Of Barn Owls (Tyto Alba) Nesting At Ponca State Park, Ann Spilker, Joseph A. Gubanyi Sep 2017

Diet And Habitat Analysis Of Barn Owls (Tyto Alba) Nesting At Ponca State Park, Ann Spilker, Joseph A. Gubanyi

Nebraska Bird Review

In 2015 Barn Owls (Tyto alba) nested on the floor of a grain bin in Ponca State Park, Dixon County. Seven nestlings were observed (Figure 1). It is believed that 6 fledged (one carcass was found on the floor of the bin September 26). Barn Owls were not observed the following spring (Jan Johnson, personal communication). Because there are few records of Barn Owls in the region, we collected data to better understand the Barn Owl nesting in Ponca State Park. Barn Owl prey and their importance to reproductive success has been well documented (Marti et al. 2005; Gubanyi et …

Herons And Egrets, Michael D. Hoy Aug 2017

Herons And Egrets, Michael D. Hoy

Wildlife Damage Management Technical Series

Human-Wildlife Conflicts

Landscapes -- Herons and egrets commonly cause damage at aquaculture facilities and recreational fishing waters where fish are held at high densities. In one study, on average wading birds consumed from 4 to 24 golden shiners per day at minnow production facilities in Arkansas. Great blue herons and great egrets commonly feed at catfish production facilities in Mississippi. The tendency for herons and egrets to congregate in large feeding flocks often leads to extensive loss of fish at aquaculture facilities. Fish-eating birds also can have an impact on intensively managed sport fisheries. Damage occurs when herons and egrets …


Nou Spring Field Days And Annual Meeting, Auburn, May 19-21, 2017, Janis Paseka Jun 2017

Nou Spring Field Days And Annual Meeting, Auburn, May 19-21, 2017, Janis Paseka

Nebraska Bird Review

The annual meeting of the Nebraska Ornithologists’ Union was held at the Senior Center in Auburn on May 19-21, 2017, and was organized by Robin Harding and Don and Janis Paseka. About 70 birders attended on a weekend that began wet but finished with more birder-friendly conditions. Our Friday evening program was a presentation by Kevin Holliday, Superintendent of Indian Cave State Park. He mentioned the park’s features including the cave and petroglyphs, St. Deroin cemetery, 22 miles of trails, Missouri River overlook and reconstructed town. He also highlighted the many events held in the park during the year, including …


Greater Sandhill Crane (Antigone Canadensis Tabida) Copulation Detected Along The Big Bend Of The Platte River, South-Central Nebraska, Andrew J. Caven, Emma M. Brinley Buckley Jun 2017

Greater Sandhill Crane (Antigone Canadensis Tabida) Copulation Detected Along The Big Bend Of The Platte River, South-Central Nebraska, Andrew J. Caven, Emma M. Brinley Buckley

Nebraska Bird Review

On 9 March 2017 at 0805 hrs, two A. canadensis tabida were observed copulating on a sandy island within the south channel of the Platte River, Hall County, Nebraska (40.790982°N, -98.404635°W, WGS84; 581 m elev.). Two biologists witnessed the copulation at a distance of about 175 m looking to the south from within an overnight viewing blind on the north bank of the south channel of the Platte River, utilizing an 80 mm spotting scope (20x60x magnification). The sequence of events previous to the copulation followed very closely the observations reported by Tacha (1988). The copulation was proceeded by the …

Spring Field Report, March-May 2017, W. Ross Silcock

Nebraska Bird Review

In general, this was a routine spring, except for remarkable numbers reported of several species, and a notable paucity of most species of wood-warblers. A huge Snow Goose flock in the east was estimated to contain 500,000- 1,000,000 birds; other notable numbers were 2000 Tree Swallows and 5000 Cliff Swallows, both record counts, 44 Black-capped Chickadees, 300 House Wrens, 62 Fox and 76 Song Sparrows on the same day at a single location, 168 Dark-eyed (Slate-colored) Juncos, and 10,000 Common Grackles. Perhaps the most notable phenomenon this spring was the dearth of migrant wood-warblers. Joel Jorgensen constructed graphics based on …


The North American Whistling-Ducks, Pochards, And Stifftails, Paul A. Johnsgard Mar 2017

The North American Whistling-Ducks, Pochards, And Stifftails, Paul A. Johnsgard

Zea E-Books Collection

Although the 12 species representing three waterfowl tribes described in this volume are not closely related, they fortuitously provide an instructive example of adaptive evolutionary radiation within the much larger waterfowl lineage (the family Anatidae), especially as to their divergent morphologies, life histories, and social behaviors.

The whistling-ducks (Dendrocygna), with three known North American species, are notable for their permanent pair-bonds, extended biparental family care, and strong social cohesion. In contrast, males of the five typical pochards of North American diving ducks (Aythya) establish monogamous pair-bonds that are maintained only long enough to assure that the female’s eggs are fertilized. …


Hitching A Ride: First Record Of A Least Chipmunk (Tamias Minimus) In Eastern Nebraska, Keith Geluso, Michael L. Forsberg Mar 2017

Hitching A Ride: First Record Of A Least Chipmunk (Tamias Minimus) In Eastern Nebraska, Keith Geluso, Michael L. Forsberg

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

On 10 October 2016, a Least Chipmunk (Tamias minimus) was discovered in a residential area of Lincoln, Lancaster County, Nebraska. The closest populations of Least Chipmunks reside > 640 km to the west in northwestern Nebraska and southeastern Wyoming. The most parsimonious explanation for this unusual observation is that the chipmunk was transported to the city by humans. A likely scenario is that the chipmunk hitched a ride to Lincoln in a motor vehicle on 2 October 2016, when one of us drove 1500 km in a single day from Jackson, Teton County, Wyoming, after residing in that area …


Biotic And Abiotic Factors Predicting The Global Distribution And Population Density Of An Invasive Large Mammal, Jesse S. Lewis, Mathew L. Farnsworth, Christopher L. Burdett, David M. Theobald, Miranda Gray, Ryan S. Miller Mar 2017

Biotic And Abiotic Factors Predicting The Global Distribution And Population Density Of An Invasive Large Mammal, Jesse S. Lewis, Mathew L. Farnsworth, Christopher L. Burdett, David M. Theobald, Miranda Gray, Ryan S. Miller

Other Publications in Wildlife Management

Biotic and abiotic factors are increasingly acknowledged to synergistically shape broad-scale species distributions. However, the relative importance of biotic and abiotic factors in predicting species distributions is unclear. In particular, biotic factors, such as predation and vegetation, including those resulting from anthropogenic land-use change, are underrepresented in species distribution modeling, but could improve model predictions. Using generalized linear models and model selection techniques, we used 129 estimates of population density of wild pigs (Sus scrofa) from 5 continents to evaluate the relative importance, magnitude, and direction of biotic and abiotic factors in predicting population density of an invasive large mammal …


Beavers, Jimmy D. Taylor, Greg K. Yarrow, James E. Miller Mar 2017

Beavers, Jimmy D. Taylor, Greg K. Yarrow, James E. Miller

Wildlife Damage Management Technical Series

The American beaver (Castor canadensis) (Figure 1) is known as an “ecosystem engineer” because of the benefits their dams provide to biological diversity and ecosystem function. It also is considered a “keystone species” because of its ability to transform its environment, creating new habitats upon which other species depend. Despite the many positive benefits beavers provide through foraging and dam building, beavers also create conflict with people when their activities cause damage. The authors of this publication acknowledge and appreciate the many positive benefits that beavers provide; however, the focus of this publication is to provide basic information on beaver …


2016 Christmas Bird Counts, Don Paseka Mar 2017

2016 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Fourteen Nebraska counts were held during the 2016 CBC season, which is one less than last year. The Harrison and Crawford counts were cancelled this year, but in the opposite corner of the state, a new count was started that includes Indian Cave State Park. An unusually mild November and a seasonable start to December were followed by a modest cold snap during the second week of the month. The Harlan County count was run early in the period on the 15th with ample open water, and it produced a record number of species (90) for that circle. But in …


Brambling In Bellevue, Sarpy County, Loren Padelford, Babs Padelford Mar 2017

Brambling In Bellevue, Sarpy County, Loren Padelford, Babs Padelford

Nebraska Bird Review

As we were having breakfast on January 8, 2017, we spotted an unusuallooking bird with House Sparrows in the tree above our deck. After consulting the National Geographic field guide, we determined it was a Brambling. Soon it was feeding on the deck where we were able to get some photos. It was first spotted at 9:25 a.m. and again at 10:30. We put the information on NEBirds and by late morning birders began to arrive.The first group saw the bird at 12:02. By early afternoon we had standing room only in our family room. The bird appeared again at …

Winter Field Report, December 2016 To February 2017, W. Ross Silcock Mar 2017

Winter Field Report, December 2016 To February 2017, W. Ross Silcock

Nebraska Bird Review

This was an interesting winter from several standpoints. The trend of unexpected winter occurrences and earlier arrivals in “spring” continued. Mid-winter records of several species were notable: Rock Wren, Marsh Wren, American Pipit, Pine Warbler, and Chipping Sparrow. Rarities (see below) that could be considered in this category as well were Golden-crowned Sparrow and Lesser Goldfinch. For earlier arrivals, there was a noticeable influx 14-18 Feb of various species that provided rather early dates for those species. In this group were Blue-winged Teal, Ruddy Duck, Double-crested Cormorant, American White Pelican, and Turkey Vulture.

Some amazing numbers were reported, including a …


Geographic Distribution: Acrantophis Dumerili (Duméril’S Madagascan Ground Boa). Usa. Florida., Louis A. Somma, Kenneth L. Krysko, Laurence L. Conner Jan 2017

Geographic Distribution: Acrantophis Dumerili (Duméril’S Madagascan Ground Boa). Usa. Florida., Louis A. Somma, Kenneth L. Krysko, Laurence L. Conner

Papers in Herpetology

The geographic distribution of Acrantophis dumerili, a nonindigenous introduced species in Florida, with new records, is presented.

Acrantophis dumerili is indigenous to southern and southwestern Madagascar. We provide the first vouchers for Miami-Dade and Bay counties, which were likely escaped or released pets. Florida already has three established species of booid snakes (one boa, two pythons), all introduced through the pet trade pathway. Although there is no clear evidence for an established population of A. dumerili in Florida at this time, the Bay County individuals in a rural area in the Florida panhandle are a particular concern given that two …


Sandhill And Whooping Cranes, Jeb Barzen, Ken Ballinger Jan 2017

Sandhill And Whooping Cranes, Jeb Barzen, Ken Ballinger

Wildlife Damage Management Technical Series

As sandhill crane populations continue to grow in the United States, so too does crop damage, property damage to homeowners, and the risk of crane collisions with aircraft. Whooping crane populations also continue to grow, but with a global population of about 500 individuals (as of 2017), damage is rare and problems often require different solutions due to the species’ endangered status. The behavioral characteristics and habitat needs of sandhill and whooping cranes set the stage for conflict between these birds and people. Recognizing behavioral differences between territorial and non-territorial cranes greatly improves the effectiveness of any management effort.

Wildlife At Airports, Travis L. Devault, Bradley F. Blackwell, Jerrold L. Belant, Michael J. Begier Jan 2017

Wildlife At Airports, Travis L. Devault, Bradley F. Blackwell, Jerrold L. Belant, Michael J. Begier

Wildlife Damage Management Technical Series

Collisions between aircraft and wildlife (wildlife strikes) are common occurrences across the developed world. Wildlife strikes are not only numerous, but also costly. Estimates suggest that wildlife strikes cost the civil aviation industry in the U.S. up to $625 million annually, and nearly 500 people have been killed in wildlife strikes worldwide. Most wildlife strikes occur in the airport environment: 72 percent of all strikes occur when the aircraft is ≤500 ft (152 m) above ground level, and 41 percent of strikes occur when the aircraft is on the ground during landing or takeoff. Thus, management efforts to reduce wildlife …


Biotic Interchange Has Structured Western Hemisphere Mammal Communities, Danielle Fraser, S. Kathleen Lyons Jan 2017

Biotic Interchange Has Structured Western Hemisphere Mammal Communities, Danielle Fraser, S. Kathleen Lyons

School of Biological Sciences: Faculty Publications

Aim.— Many hypotheses posit that species-rich tropical communities are dominated by speciesspecies interactions, apparent as competitive exclusion or character displacement, whereas species-poor temperate communities are dominated by species-environment interactions. Recent studies demonstrate a strong influence of macroevolutionary and biogeographic factors. We simultaneously test for the effects of species interactions, climate, and biotic interchange on Western Hemisphere mammal communities using a phylogenetic and functional diversity approach.

Location.— Western Hemisphere.

Time period.— Modern

Major taxa studied.— Mammalia

Methods.— Using Western Hemisphere mammal distributional and body mass data, we calculate body mass dispersion, phylogenetic diversity (Net Relatedness Index), and assemblage-averaged rates of co-occurrence …


Assessment Of A Channel Catfish Population In A Large Open River System, A. J. Blank, M. J. Hamel, Jonathan J. Spurgeon, Mark A. Pegg Jan 2017

Assessment Of A Channel Catfish Population In A Large Open River System, A. J. Blank, M. J. Hamel, Jonathan J. Spurgeon, Mark A. Pegg

School of Natural Resources: Faculty Publications

Estimates of dynamic rate functions for riverine channel catfish, Ictalurus punctatus (Rafinesque), populations are limited. The open nature and inherent difficulty in sampling riverine environments and the propensity for dispersal of channel catfish impede estimation of population variables. However, contemporary population models (i.e. robust design models) can incorporate the open nature of these systems. The purpose of this study was to determine channel catfish population abundance, survival and size structure and to characterize growth in the lower Platte River, Nebraska, USA. Annual survival estimates of adult channel catfish were 13%–49%, and channel catfish abundance estimates ranged from 8,281 to 24,261 …
