2019 Hitchcock Raptor Banding Project In Perspective, Jerry Toll
2019 Hitchcock Raptor Banding Project In Perspective, Jerry Toll
Nebraska Bird Review
Hitchcock Nature Center in Pottawattamie County, north of Crescent, Iowa, is home to the Hitchcock HawkWatch and Raptor Banding Project. The Nature Center is in the heart of the Loess Hills which, together with the flat expanse of the Missouri River Valley to the west, provides the perfect conditions for creating the updraft that aids migrating birds. The Hawkwatch began in 1992, and every fall from September through December, birds-of-prey enthusiasts gather on the 45-foot observation tower to watch and count thousands of eagles, hawks, and other raptors as they migrate south. Every year since 2007, Sandy Reinken and I …

Summer Field Report, June - July 2019, W. Ross Silcock
Nebraska Bird Review
There was a lot to ponder this summer, including several notable breeding records of waterbirds, including the 3rd for Canvasback and an “unprecedented” breeding season for Eared Grebe in the Rainwater Basin. Intriguing summer occurrences that might presage or indicate nesting were large numbers of Redhead and Ring-necked Duck in larger wetlands, the 3rd Jun record of Dusky Flycatcher, first Jun record of Baird’s Sparrow, 3rd summer record of Ash-throated Flycatcher, and a Sage Thrasher in Jun in Kimball County. Additional breeding records of interest were the 10 Peregrine Falcons fledged at three Omaha sites, possible nesting by Mississippi Kites …

New Wilson’S Phalarope Nesting Record From The Central Platte River Valley, Mormon Island, Hall County, Nebraska, Andrew J. Caven, Bethany L. Ostrom, Aurora Fowler, Joshua D. Wiese, Kelsey C. King
Nebraska Bird Review
The southeastern portion of the Wilson’s Phalarope’s (Phalaropus tricolor) breeding range encompasses parts of Nebraska (Colwell and Jehl 1994), including the Sandhills and northern Panhandle (Silcock and Jorgensen 2018). Additionally, there have been a number of breeding records from southcentral and southeastern Nebraska within the Rainwater Basin ecoregion since the mid-1990s (Mollhoff 2016, Silcock and Jorgensen 2018). However, there is very little evidence of regular breeding activity in the nearby Central Platte River Valley (CPRV), which spans from Chapman west to Overton, Nebraska, and is considered a globally important area for waterbirds (Johnsgard and Brown 2013, Silcock and Jorgensen 2018). …

Spring Field Report, March - May 2019, W. Ross Silcock
Nebraska Bird Review
There were many significant reports, including high and low numbers, early and late dates, out-of-range sightings including nesting, and, of course, rarities. High numbers were led by geese; an amazing 1.7 million Snows were estimated by acreage (!) and counts of 10,000 Greater White-fronted and 100,000 Canada Geese were near-record high counts for spring. A bit surprising as record spring counts were 3000 European Starlings and 3000 American White Pelicans. Nightjar surveys by Nebraska Game and Parks Commission and others yielded an amazing 40+ Chuck-will’s-widows in the southeast; Ruddy Turnstones put on a show with 85 in Platte Co; 127 …
Book Review: Sparrows Of North America By Rick Wright, W. Ross Silcock
Book Review: Sparrows Of North America By Rick Wright, W. Ross Silcock
Nebraska Bird Review
This book is a tour de force.
Not only is it a comprehensive summary of field identification, range, and taxonomy of species of the New World family Passerellidae, but the introductory paragraphs for each species, which describe the provenance of the English and Latin species names we know today, read like a historical novel that is a perfect vehicle for Wright to display his well-known erudition and could quite justifiably stand alone. Wright’s extensive research into often obscure places and sources that may be penetrated and interpreted only by one with his classical literary background is clear in these historical …

The NOU Annual Meeting and Spring Field Days, organized by Jan Johnson, was held in Fairbury on May 17-19, 2019, with 64 in attendance. Our meetings and meals took place in the 4-H building at the Jefferson County Fairgrounds. Despite the forecast for rain, the weather was perfect on Saturday morning, with rain arriving only in the late afternoon. Wind made listening for nightjars difficult on both evenings and it continued to be a problem on Sunday, but the total species list for the meeting was 165.

The Role Of Endangered Oak (Quercus Spp.) Savanna Characteristics In Supporting Red-Headed Woodpecker (Melanerpes Erythrocephalus L.) Populations, Kimberly J. Zralka
The Role Of Endangered Oak (Quercus Spp.) Savanna Characteristics In Supporting Red-Headed Woodpecker (Melanerpes Erythrocephalus L.) Populations, Kimberly J. Zralka
Honors Program Projects
Declines in animal populations worldwide are of critical conservation concern. However, without an understanding of optimal habitat preference, it is often difficult to determine what factors are driving these losses. Red-headed woodpecker (Melanerpes erythrocephalus L.) populations have declined by over 70% in the last 50 years, yet in some areas the birds seem to maintain stable populations. The aim of this study was to empirically test the effects of various habitat factors on red-headed woodpecker presence and abundance in both the summer and winter seasons. As oak acorns are a critical food source for this bird, we were particularly …
The Piping Plover Problem: A Review Of Management Issues For A Threatened Shorebird, Andrew Lydeard, Gerry Harris
The Piping Plover Problem: A Review Of Management Issues For A Threatened Shorebird, Andrew Lydeard, Gerry Harris
Scholars Week
Andrew Lydeard and Gerry Harris
The Piping Plover (Charadrius melodus) was federally listed in 1986. Since listing, Piping Plovers have been a focus of conservation and management efforts, particularly on their breeding grounds in the Northern Great Plains, Great Lakes, and northern Atlantic Coast. Despite management efforts that have resulted in range-wide population growth of the Piping Plover, growth in individual populations is often slow and reasons for this are poorly understood. A bias towards understanding drivers of declines on breeding sites compared to wintering and migratory stopover sites may be an underlying cause of this lack of …
Climate Change Impacts On Bird Communities Vary Throughout Cities In Kansas, Lindsey Williams, Christine Brodsky
Climate Change Impacts On Bird Communities Vary Throughout Cities In Kansas, Lindsey Williams, Christine Brodsky
Posters
It is important to study climate change’s impacts on biodiversity in order to find a solution before the effects on wildlife are irreversible. Our research objective for this project was to determine if climate change affected long-term bird trends in urban and rural areas throughout Kansas. Our hypothesis was that climate change will decrease bird abundance and species richness because altered climate patterns like storms, droughts, and heat waves, may cause a decrease in suitable habitat. We would expect these trends to be strongest in cities, due to the urban heat island effect. The methods used for this project included …

Daniel Cristol
Understanding the role of green space in urban—suburban landscapes is becoming critical for bird conservation because of rampant habitat loss and conversion. Although not natural habitat, golf courses could play a role in bird conservation if they support breeding populations of some native species, yet scientists remain skeptical. In 2003–2009, we measured reproduction of Eastern Bluebirds (Siala sialis) in Virginia on golf courses and surrounding reference habitats, of the type that would have been present had golf courses not been developed on these sites (e.g., recreational parks, cemeteries, agriculture land, and college campus). We monitored >650 nest boxes …

2018-2019 Christmas Bird Counts, Don Paseka
Nebraska Bird Review
Eighteen counts were held during the 2018-19 Christmas Bird Count season. This is two more than were done last season, which was the first time that as many as sixteen counts were held. This year no counts were postponed or cancelled, and the Beaver Valley Count was revived after a four year hiatus. Twelve of the counts were done during the first week of the count period. While the conditions for these early counts were mild and dry, heavy precipitation in late fall coupled with an early onset of cold weather in the first part of December resulted in little …

Winter Field Report, December 2018 To February 2019, W. Ross Silcock
Nebraska Bird Review
As has been the trend in recent winters, and despite the relative coolness of this winter, there were numerous examples of species north of expected midwinter ranges or present in higher numbers than usual in winter. The long list includes unexpected midwinter records of Tundra Swan, American Wigeon, Ring-necked Duck, Lesser Scaup, White-winged Dove, Sandhill Crane, Clark’s Grebe, Doublecrested Cormorant, Red-shouldered Hawk, and Yellow-bellied Sapsucker. Startling was the state’s first winter record of Sedge Wren, perhaps the biggest rarity of the season. And Eastern Meadowlark was documented in midwinter for the first time, although its presence in the southeast has …

Summary
The Great Plains of North America is defined as the land mass that encompasses the entire central portion of the North American continent that, at the time of European settlement, was an unbroken expanse of primarily herbaceous vegetation. The Great Plains extend from central Saskatchewan and Alberta to central Mexico and from Indiana to the Rocky Mountains. The expanses of herbaceous vegetation are often referred to as native prairie or native grasslands. Native grasslands share the characteristics of a general uniformity in vegetation structure, dominance by grasses and forbs, a near absence of trees and shrubs, annual precipitation ranging …
Where Birds Chill: An Assessment Of The Habitat Preferences Of Birds Overwintering In Hudson Valley Forests, Elizabeth Claire Axley
Where Birds Chill: An Assessment Of The Habitat Preferences Of Birds Overwintering In Hudson Valley Forests, Elizabeth Claire Axley
Senior Projects Spring 2019
Many avian species overwinter in eastern North America; however, studies on bird populations are rarely undertaken during this critical survival time, and little is known as to their habitat preferences and foraging behavior. In this observational study, we performed a survey of birds overwintering in the Hudson Valley’s temperate, primarily-deciduous forests, assessing avian populations’ habitat preferences through the vegetative structural variables surrounding overwintering birds as they forage. Our results suggest that high canopy cover is critically important to predicting overwintering bird occupancy on a microhabitat scale. Moreover, overwintering birds preferentially occupy forest plots not dominated by sugar maples, in spite …
Fall Field Report, August - November 2019, W. Ross Silcock
Fall Field Report, August - November 2019, W. Ross Silcock
Nebraska Bird Review
By far the most striking feature of this fall’s report is the large number of lingering migrants, a trend that is continuing and apparently increasing, especially among passerines. Editor Jan Paseka counted 17 uses of the word “tardy” and 43 of “late” or “latest”. It is tempting to relate this to the warmer environment and resulting increased availability of food items at higher latitudes and later dates than in previous years. A sad note: a startling occurrence in Gering, Scotts Bluff 20 Aug was described by Marie Smith: “We had a huge hailstorm around 10:30. The hail was probably pea …

Comparison Of Conservation Policy Benefits For An Umbrella And Related Sagebrush-Obligate Species, Jonathan B. Dinkins, Jeffrey L. Beck
Human–Wildlife Interactions
Many conservation strategies promote the potential of multiple species benefitting from protection of large areas necessary for the continued viability of 1 species. One prominent strategy in western North America is Wyoming’s Sage-grouse Core Area Policy, which was designed to conserve greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) breeding habitat, but may also serve as an umbrella to conserve other sagebrush (Artemisia spp.)-obligate wildlife, including songbirds. Sagebrush-obligate songbirds and sage-grouse have undergone population declines throughout the western United States attributed to similar habitat issues. We compared trends of sagebrush-obligate songbirds from the Breeding Bird Survey and sage-grouse lek …
