Possible Double-Brooding In Scissor-Tailed Flycatcher (Tyrannus Forficatus), Wayne Mollhoff Sep 2018

Possible Double-Brooding In Scissor-Tailed Flycatcher (Tyrannus Forficatus), Wayne Mollhoff

Nebraska Bird Review

In a follow-up visit to the site near Alexandria, Thayer Co., where I documented a Scissor-tailed Flycatcher nest with eggs in 2017, I found a pair present at the same site on 8 June 2018. After some searching, I found that their nest, with 4 eggs, was built in the same upright crotch of the same branch where it was located the year before. I knew it was a completely new nest, since the previous nest had been removed after the nesting season the year before. On a second visit on 13 August 2018, to see if the birds and/or …

Summer Field Report, June-July 2018, W. Ross Silcock

Nebraska Bird Review

This was a rather lackluster summer season, notably among waterfowl, shorebirds, and gulls. However, the discovery of a couple of amazing rarities spiced things up. Not only were there a few reports of the increasing Black-bellied Whistling- Duck, but the Fulvous Whistling-Ducks in Lancaster Co were a first state record, albeit a bit overdue. Another major rarity was a Reddish Egret, Nebraska’s third, in Hall Co, seen by almost as many folks as the Fulvous Whistling-Ducks. Close behind were the 6th and 7th Nebraska records of Black-chinned Hummingbird, probably on its way to regular occurrence in the next few years. …

Common Loons Respond Adaptively To A Black Fly That Reduces Nesting Success, Walter H. Piper, Keren B. Tischler, Andrew Reinke Jun 2018

Common Loons Respond Adaptively To A Black Fly That Reduces Nesting Success, Walter H. Piper, Keren B. Tischler, Andrew Reinke

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Nesting birds must often cope with harassment from biting insects, but it is difficult to ascertain what effect such pests might have on breeding success and population dynamics. We tested the hypothesis that a black fly (Simulium annulus) that feeds on the blood of nesting Common Loons (Gavia immer) causes nest abandonment in this charismatic diving bird. In addition, we measured effects of fly-induced abandonment on a loon population, and examined potential predictors of fly abundance and nest abandonment. We also tested a second hypothesis, which holds that loon pairs that abandon a nest owing to …

Nou Spring Field Days And Annual Meeting, Ft. Robinson, May 18-20, 2018, Janis Paseka

Nebraska Bird Review

The NOU Annual Meeting and Spring Field Days, organized by Robin Harding, Jan Johnson and Ruth Stearns, was held at Ft. Robinson State Park in Dawes and Sioux Counties on May 18-20, 2018, with 82 in attendance. Our lodgings and meeting room were in reconstructed buildings of the old Fort. The weather was perfect on Friday and Sunday but perfectly awful on Saturday, with rain all day and a high of 44°F. Finding birds and driving on unpaved roads was challenging on Friday, but the total species list for the meeting is 180. Field trips were led by Kathy DeLara, …

Spring Field Report, March - May 2018, W. Ross Silcock

Nebraska Bird Review

This spring will be remembered for Nebraska’s first unequivocal record of Swainson’s Warbler, unfortunately a “one day wonder”, but well-photographed. Another mega was a Band-tailed Pigeon, Nebraska’s fourth. The old sports saying “wait until next year” was applicable in spades to woodwarblers; last year was noted for its paucity of most species of wood-warblers, but this year, incredible record numbers occurred for several migrant species: Magnolia, Baybreasted, Chestnut-sided, Blackpoll, and Palm. Other amazing numbers were the 598,000 Sandhill Cranes counted at peak migration in the Central Platte Valley and the 598 Great Egrets reported within the amazing 414 reports. Several …


First Record Of Fulvous Whistling-Duck (Dendrocygna Bicolor) For Nebraska, Matthew T. Haugen Jun 2018

First Record Of Fulvous Whistling-Duck (Dendrocygna Bicolor) For Nebraska, Matthew T. Haugen

Nebraska Bird Review

On the afternoon of 5 June 2018, I was scouting local Salt Valley lakes to get an estimate of goose numbers for annual Canada Goose (Branta canadensis) banding operations. At approximately 2:30 p.m. I was tallying my goose counts in the northwest corner of Wagon Train Wildlife Management Area in Lancaster County, when I noticed four ducks on a nearby vegetated mud flat. After closer examination, I recognized the ducks as Fulvous Whistling-Ducks (Dendrocygna bicolor). I spent a few years working in Louisiana in that state’s waterfowl program, and I am familiar with the species and its identification. I was …

Winter Field Report, December 2017 To February 2018, W. Ross Silcock

Nebraska Bird Review

This was not a spectacular fall by most measures, but, as usual, there was much to chew on. Continuing the trend seen in recent falls, lingering has become the norm; this phenomenon is across the board, involving, for example, Baird’s Sandpiper, Greater Yellowlegs, Mourning Dove, American White Pelican, Barn Owl, Lesser Goldfinch, several native sparrow species, Palm and Orange-crowned Warblers, and even rearof- the-order Dickcissel. Apparent range expansion is occurring with Red-shouldered Hawk and Barred Owl, the former northward and the latter westward. A couple of taxonomic notes relate to the subspecies Buteo jamaicensis abieticola of Red-tailed Hawk and subspecies …

2017-2018 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Sixteen counts were held during the 2017-18 Christmas Bird Count season, which is one more than has ever been done in the past. Although the Crawford count was not done this season, the new Lower Platte River count, centered at the junction of Platteview Road and 204th St. south of Gretna, was added. A total 236 observers took part in at least one count, 26 did two counts, four did three counts, five did four counts and four persons did six counts. However, special recognition goes to Gary Roberts, who did eight counts this season. I am not aware of …

Ms Environmental Biology Capstone Project, Taylor Readyhough

Regis University Student Publications (comprehensive collection)

Life in a zoo brings a score of stressors into the lives of captive animals, including artificial light, crowds of visitors, and increased noise levels. Stress especially impacts captive birds, and continued exposure to these stressors can negatively affect birds’ reproductive success and overall well-being. Staff at the Denver Zoo noticed increased aggression between a male and female pair of great Indian hornbills during the winter of 2016. This behavioral shift coincided with Zoo Lights, a holiday event that results in the hornbills’ exhibit remaining open to the public for approximately four extra hours through the entire month of December. …


Ainsworth Fall Field Days, Janis Paseka Jan 2018

Ainsworth Fall Field Days, Janis Paseka

Nebraska Bird Review

The 2018 NOU Fall Field Days took place in and around Ainsworth on Sep. 14 – 16, with 48 in attendance. It was a hot and windy weekend, but 137 species were located. Two Sandhill Cranes in the Niobrara River at the Carns Bridge attracted birders, especially since the two cooperatively moved from one side of the river to the other, allowing county listers to count them in both. The bird of the weekend, however, was the Red-naped Sapsucker at Plum Creek Valley WMA. It was a county bird for everyone, a state bird for many and a life bird …


Do Avian Blood Parasites Influence Hypoxia Physiology In A High Elevation Environment?, Farah Ishtiaq, Sahas Barve Jan 2018

Do Avian Blood Parasites Influence Hypoxia Physiology In A High Elevation Environment?, Farah Ishtiaq, Sahas Barve

Biological Sciences Faculty Publications

BACKGROUND: Montane birds which engage in elevational movements have evolved to cope with fluctuations in environmental hypoxia, through changes in physiological parameters associated with blood oxygen-carrying capacity such as haemoglobin concentration (Hb) and haematocrit (Hct). In particular, elevational migrants which winter at low elevations, encounter varying intensities of avian haemosporidian parasites as they traverse heterogeneous environments. Whilst high intensity parasite infections lead to anaemia, one can expect that the ability to cope with haemosporidian infections should be a key trait for elevational migrants that must be balanced against reducing the oxygen-carrying capacity of blood in response to high elevation. In …

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 …

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 …


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 …


Predation On Artificial Turkey Nests At Radford Army Ammunition Plant In Western Virginia, Shane Brandes, Karen E. Powers, Len L. Diioia Jr. Oct 2017

Predation On Artificial Turkey Nests At Radford Army Ammunition Plant In Western Virginia, Shane Brandes, Karen E. Powers, Len L. Diioia Jr.

Virginia Journal of Science

Because ground-nesting wild turkeys (Meleagris gallopavo) may sustain high incidences of nest predation in western Virginia, determining their predators is essential to understanding risk and managing the birds.  Our study investigated potential predators of wild turkey nests at the Radford Army Ammunition Plant, New River Unit (RFAAP; Pulaski Co., in western Virginia). Here, we established 8 artificial nests during the breeding season for wild turkey (March-April, 2017), and documented predators via game cameras.  Thirty-one species of mammals and birds visited the nests over the 31-day study. Nest predation was verified 56 times across 6 species, including coyotes ( …


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 …

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 …

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 …
