2022 (34th) Report Of The Nou Records Committee, Mark A. Brogie

Nebraska Bird Review

The functions and methods of the Nebraska Ornithologists’ Union Records Committee (NOURC) are described in its bylaws (NOURC 2010). The committee’s purpose is to provide a procedure for documenting unusual bird sightings and to establish a list of all documented birds for Nebraska. Species for which the NOURC seeks documentation (NOURC Review List) can be found at the NOU website www.NOUbirds.org. Starting in 2020, the NOURC decided to deal mainly with those species deemed as Accidental on the “Official List of the Birds of Nebraska.” Casual species and out-of-range species are now summarized in the “Seasonal Reports” of the …

2023 Limpkin At Crystal Cove Park, Dakota County, Ne, Bill Huser

Nebraska Bird Review

On the morning of October 7, 2023, I observed Nebraska’s second Limpkin (Aramus guarauna) at Crystal Cove Park in South Sioux City, and the bird was subsequently seen by several other observers throughout that afternoon. Photo and video records were obtained (https://ebird.org/checklist/S151656716). The summer and fall of 2023 brought fourteen sightings to Iowa, though it is impossible to determine how many birds were involved (eBird, 2023). One of those sightings occurred in the northwestern part of the state at Bacon Creek Park in Sioux City when a single Limpkin was independently reported by two observers on …

Summer Field Report, June–July 2023, W. Ross Silcock

Nebraska Bird Review

There were no new species for Nebraska. This was also a lean season for records of species with few Nebraska records. Probably most significant were continuing Common Ravens in two Sioux Co locations, and possibly the first summer records of Baird’s Sparrow, a recording of the latter currently under NOURC review.

Within-state breeders nesting at new locations. There were several instances of nesting reported away from known breeding areas. These include documented records of first nesting Black-necked Stilts in Cherry Co, Least Terns off river at Offutt Base Lake in Sarpy Co, Mississippi Kite in Adams Co, Yellow-throated Vireo in …

Spring Field Report, March - May 2023, W. Ross Silcock

Nebraska Bird Review

First off, I want to reiterate that reports compiled for this Spring Seasonal Report are evaluated against current knowledge as presented in Birds of Nebraska-Online (“BONO”; https://birds.outdoornebraska.gov/). Species whose reports do not add new information on distribution, early or late dates, etc., are listed as having “Routine reports”. Please let me know at silcock@rosssilcock.com if you have information that is not in BONO, or if you have additions and/or corrections of information in BONO. Another reminder: if evidence of breeding is observed, please enter the appropriate descriptor in your eBird checklist under “Breeding and Behavior Code”. These descriptors can be …

Rethinking The Status And Temporal Occurrence Of The American Woodcock In Nebraska Because Of Its Unusual Life History, Joel G. Jorgensen, Stephen J. Brenner

Nebraska Bird Review

Historical distribution and range expansion -- We reviewed existing information to evaluate conclusions by previous authors (e.g., Sharpe et al. 2001, Silcock and Jorgensen 2023) that woodcock have expanded their range west since settlement of Nebraska by Euro-Americans. We also provide additional context about the species’ distribution over time using regional resources.

Temporal occurrence and abundance -- We used data from woodcock outfitted with satellite transmitters 2021-2022 and compared it with occurrence data from two sources, eBird (eBird.org 2023) from all years through 2022 and the SFRs in the Nebraska Bird Review 1994–2019. We chose not to use SFR data …

2022-2023 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Sixteen counts were run in the 2022-2023 CBC season. Because of weather and rescheduling issues, the Crawford, Harrison, and Harlan County counts were cancelled. Eight of the counts were completed during the first week of the count period and the other eight were scattered throughout the remainder of the count period. An early December cold snap seemed to drive many of the birds south, but the weather on actual count days was fairly benign: mostly dry with an average high of 34˚F and an average low of 19˚F and with three circles reporting light snow. The total number of species …

Winter Field Report, Dec. 2022 - Feb. 2023, W. Ross Silcock

Nebraska Bird Review

Since this is a Winter Seasonal Report, it seems appropriate to lead off with notable reports of occurrences that might be considered unexpected for midwinter, of which there were several. A range of species was involved, suggesting an encompassing cause such as climate change. Of interest were northerly wintering groups of waterfowl including Gadwall, Green-winged Teal, Canvasback, Ringnecked Duck, and Hooded Merganser. Reports of wintering Tundra Swans, Whitewinged Doves, and Lesser Goldfinches continue to increase, and numerous Redwinged Blackbirds in the northeast in midwinter were unexpected. Also quite unexpected were two Sandhill Cranes wintering in the east, the state’s first …

Schramm Park Fall Field Days, Janis Paseka

Nebraska Bird Review

The 2022 NOU Fall Field Days were held at Schramm Park State Recreation Area, south of Gretna in Sarpy County, on September 21-23, with approximately 60 in attendance. The meeting had been scheduled and cancelled twice in the two previous years due to coronavirus concerns. The total species count was 119, including a Sandhill Crane, Prairie Falcon (early for away from breeding area), Winter Wren, and early Snow Bunting. A Limpkin, which had been found in late June at Wehrspann Wetlands mitigation pond in Sarpy County and was still seen through late November in the Wehrspann Lake area, was not …

Remembering Clem Klaphake, Don Paseka

Nebraska Bird Review

Clement (Clem) Klaphake passed away on December 30, 2022, from complications of Parkinson’s disease, which he struggled with for several years. He was born in Melrose, Minnesota, in 1943 and grew up working on his parents’ dairy farm, which included the usual menagerie of other farm animals typical of that time. Perhaps it was the routine of milking twice a day, seven days a week, or the impressive scar on his leg from a boar tusk, but Clem was destined to leave the farm and become a life-long educator. ... After getting his degree in 1971, Clem was hired to …

Fall Field Report, August-November 2022, W. Ross Silcock

Nebraska Bird Review

All in all, this was a fairly uneventful fall season, although even uneventful seasons have their share of oddities and variations from the norm. A noteworthy event was a fire that took out much of the brushy habitat in Carter Canyon, Scotts Bluff Co (see photo on following page). It will be interesting to read upcoming spring reports to see what effect the fire might have had on numbers of birds that frequent brushy areas, like towhees and buntings. Optimistically, fires have attracted rare woodpeckers, with first to arrive Black-backed, which would be a first documented Nebraska record, and typically …

Summer Field Report, June-July 2022, W. Ross Silcock

Nebraska Bird Review

As always, the summer season produces surprises, and this year was no exception. Surprises fall into different categories, though: genuine statewide rarities, within-state distributional rarities, and, of course in summer, nesting records at new locations, population notes, late and early dates and high numbers, increased knowledge about subspecies in the state, and miscellaneous things of interest. These categories are covered separately below after some housekeeping comments.

“Genuine statewide rarities” were led by the first state record Limpkin found by Karen Kader and seen by many in Sarpy Co. Potential 2nd or so state records were a Mexican Duck in Scotts …

Recruitment, Cost Indexes, And Management Of Box-Nesting Wood Ducks In South Carolina And North Carolina, Emily Miller

All Theses

The wood duck (Aix sponsa) has experienced one of the most significant declines and recoveries among species of North American waterfowl (Anatidae). With enactment of the Migratory Bird Treaty Act (1918) and installation of hundreds of thousands of artificial nest structures for this cavity-nesting species in North America, wood duck populations have recovered and remain a sustainable harvested resource. However, long-term research on box-nesting wood ducks conducted at the Savannah River Ecology Laboratory, Aiken, South Carolina, has revealed uncertainty as to whether recruitment rates of yearling females from natal box-nesting populations are self-sustaining without immigration of hens from …

Histomonosis In Turkeys – Factors Influencing Transmission, Pathogenesis, And The Search For Prophylactic Or Therapeutic Compounds, Thainá Landim De Barros

Graduate Theses and Dissertations

The incidence of histomonosis has been increasing in poultry since the ban of prophylactic and therapeutic compounds. Histomonosis is caused by the protozoa Histomonas meleagridis. The objective of this dissertation was to investigate factors impacting the pathogenesis and transmission of histomonosis and to evaluate compounds that could potentially prevent or reduce the severity of histomonosis in turkeys. In the first study, the effect of sodium chlorate and sodium nitrate on reducing histomonads growth was tested in vitro and added to a basal turkey diet. A decrease in the growth of histomonads in vitro was observed, but no in vivo effect …

Spring Field Report, March-May 2022, W. Ross Silcock

Nebraska Bird Review

This spring there was a large number of interesting reports generated by active field observers, particularly in the west, where our knowledge continues to be broadened in all aspects. The main takeaway this spring was the inordinate plethora of species that matched or exceeded early arrival dates listed in BONO. There were no fewer than 70 species in this category, involving most families and genera, suggesting some overall influence on migration timing. Perhaps exceptions to these early arrivals were some lingering waterfowl and gulls although terns arrived early. Fully 50 of the early arrivers were passerines, notably including nine species …

Nebraska's birding community suffered a great loss on June 17, 2022, with the death of Lanny Randolph, an enthusiastic birder and a good friend to all of us. ... Lanny ... resolutely continued birding. In May 2022, he was able to attend the NOU meeting in Gering, and to see many of his longtime friends for the first time since the COVID pandemic. But a month later, on June 17, he was taken from us. Lanny's no longer physically present among us. But for those of us who knew him, he'll always be there in our memories, an invisible presence …
