Clark's Nutcracker At Lake Mcconaughy, Stephen J. Dinsmore

Nebraska Bird Review

On 1 November 1998 I observed a Clark's Nutcracker along the north shore of Lake McConaughy in Keith County. Specifically, the bird was along the road of the Cedar Vue Recreation Area, just east of the main boat ramp. I studied and photographed the bird from 11:32 to 11:50 a.m. I was driving along the entrance road to Cedar Vue when I spotted a bird perched in a dead tree. As I approached the tree, I was thinking about stopping when the bird suddenly took flight. The flight silhouette resembled that of a flicker, although the undulating flight and slower …

Neotropic Cormorant At Sutherland Reservoir, Stephen J. Dinsmore

Nebraska Bird Review

On 2 May, 1998, I observed a Neotropic Cormorant (Phalacrocorax brasilianus) at Sutherland Reservoir in Lincoln County, Nebraska. When I arrived at the lake, I noticed a large number of gulls and cormorants resting on some dead logs near the northwest end of the lake. I scanned the cormorants several times and kept returning to one cormorant that seemed smaller than the nearby Double-crested Cormorants. The bird was sleeping, so size was the only mark I could see well. I studied the bird from 1:54 to 2:20 p.m. I estimated the body was at least 25% smaller than …

Red-Throated Loon At Lake Mcconaughy, Stephen J. Dinsmore

Nebraska Bird Review

On 8 May 1998 I observed a Red-throated Loon at Lake McConaughy in Keith County, Nebraska. I was scanning Arthur Bay when I spotted a small loon swimming with several Western Grebes. I immediately recognized the bird as a Red-throated Loon in basic plumage. I studied and photographed the bird from 2:25 to 3:13 p.m. The bird was slightly larger and shorter-necked than a Western Grebe. The plumage was quite plain. The throat, cheek, foreneck, and underparts were white. The forehead, crown, nape, mantle, and wings were dark gray with a few pale spots on the mantle. The bill was …

Roseate Spoonbill In Otoe County, Stephen J. Dinsmore

Nebraska Bird Review

On 5 August 1997, W. Ross Silcock and I were birding the heron roost at the Waubonsie Wildlife Area in Fremont County, Iowa. We were hoping to see the Roseate Spoonbill I found there on 4 August (see Dinsmore 1998), and thought there might be a chance it would fly into Nebraska upon leaving the roost. At 5:53 a.m., the bird left the roost. It flew directly over us (in Iowa) and headed to the north with a Great Egret. We continued to watch the bird as it gained altitude and was joined by a second Great Egret. The birds …

Spring Field Report, March To May 1999, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

This spring proved an exciting season for several reasons. For warbler fans, it described a dream with lots of birds to look at and a rather incredible species count (for anywhere) of no fewer than 381 Many "eastern" warblers were found westward, especially at "islands" of habitat such as the Geneva Cemetery and similar spots just beyond the western edge of the original eastern woodland region, as well as the Panhandle. For rarity counters, spring included no fewer than 4 first state records: Glossy Ibis, Gray Flycatcher, Black-throated Gray Warbler, and Brambling. We make here a special note that the …

Nou Fall Field Days Count, 1998; May Namc Count, 1999

Nebraska Bird Review

The NOU count during Fall Field Days, October 16 through 18, focused on areas in and around the Nebraska National Forest and includes reports from 5 counties: Forest, Blaine, Brown, Cherry, and Thomas. This year's species count, owing in part to inclement weather, registered only 92, far behind the previous year's NOU Fall Field Days record of 122 species.

The North American Migration Count (NAMC) for Pierce County is also included in this report. A total of twelve people in five parties took part in this year's count. The count registered one hour walked and 380 miles covered in 43.5 …

Modeling Habitat Attributes Of Cavity-Nesting Birds In The Uinta Mountains, Utah: A Hierarchical Approach, Joshua J. Lawler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Birds may have the ability to view their environments at a wide range of spatial scales; accordingly, they may make habitat-selection decisions at multiple spatial scales. I investigated the implications of hierarchy theory and a landscape perspective on nest-site selection in cavity-nesting birds in the Uinta Mountains in northeastern Utah. I used three different approaches to address the concept of a multi-scaled nest-site selection process. First, I conducted an exploratory study in which I investigated nest-site selection at three spatial scales for Red-naped Sapsucker (Sphyrapicus nuchalis), Northern Flicker (Colaptes auratus), Tree Swallow (Tachycineta bicolor), and …

Between 1977 and 1988, 132 juvenile whooping cranes were color-marked on the breeding grounds; of these 37 were accounted for during the winter of 1998-99. Five color-marked cranes were observed during the fall migration. All sightings of color-marked cranes during migration are maintained at the Grand Island office.

One hundred eighty-one cranes began the 1998 spring migration. Forty-nine nests were confirmed on the breeding grounds. Forty-seven chicks were located during June surveys, and the surveys during August determined that at least 24 chicks were surviving. Under optimum conditions about 2,054 birds were expected to arrive at Aransas last fall. The …

The 1998-99 Nebraska Christmas Bird Count Summary, Stephen J. Dinsmore

Nebraska Bird Review

The 1998-99 Christmas Bird Count (CBC) period included eight counts in Nebraska. Counts were scattered statewide, but most effort was in the eastern half of the state. I know of at least one additional count (Branched Oak Lake) that was run this year, but not submitted.

In the following discussion, I have attempted to discuss what I believe are the more important aspects of this year's CBC period. This includes my general impressions about some of the commoner species, mention of rarities, notable misses, and other topics.

Winter Field Report, Dec 1998-Feb 1999, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

First we want to correct a rather obvious error in the Summer Field Report. We reported 3 pairs of Cordilleran Flycatchers at Neale Woods at the eastern edge of the state, which would be a remarkable range expansion. These birds were actually in Monroe Canyon, Sioux Co, where they were supposed to be. Another error involved 5 Brewer's Sparrows we said were in Sioux Co; these were actually Brewer's Blackbirds.

Several contributors now report to us by email. We urge observers to forward their email addresses; if we have questions on their reports, communication would be easy! Reports and comments …

On 5 March 1999, a report appeared on the listserver of a Common Crane sighted at 2:30 p.m. that day by Tammy VerCauteren (fide Paul Tebbel) about 2 miles east of Lowell Road in southeastern Buffalo County. The next morning, WRS drove to the location. After about 2 hours of searching, he refound the Common Crane at 8:57 a.m. among Sandhill Cranes about 50 meters south of Elm Island Road at a spot 2 miles east of Lowell Road. It was refound by SJD at 11:00 a.m. on March 9 northeast of the junction of roads X and 41 in …

The Age Of Birds In Nebraska, Paul A. Johnsgard

Nebraska Bird Review

Let each mile of highway I-80 represent a million years. That way, 1/2 mile represents 500,000 years, 1/10 mile = 100,000 years, 1/100 mile (52 feet) = 10,000 years; 1/1000 mile (5.2 feet) = 1,000 years, and 6 inches = 100 years. A decade (ten years) equals about a half-inch. It is 450 miles from the 60th St. on-ramp to I-80 in Omaha to the westernmost exit at the Wyoming border. These 450 million years encompass most of the time that evidence of life has been found on earth, but the earth itself is more than four billion years old, …

Two Winter Records Of Pacific Loons At Lake Mcconaughy, Stephen J. Dinsmore

Nebraska Bird Review

Pacific Loons are rare migrants in Nebraska, with most of the recent records coming from the western half of the state. Many of the recent records are from Lake McConaughy in Keith County and from Lake Minatare in Scotts Bluff County. Most records are from fall in the short period between 20 October and 20 November. There is a single spring record from April, 5 summer records in the period June to August (all but one from western Nebraska), and a few fall records outside the peak period. The latest fall record from Nebraska is 9 December. In this note, …

Fall 1998 Raptor Migrations Study In The Wellsville Mountains Of Northern Utah, United States Department Of Agriculture, Forest Service

Elusive Documents

The Wellsville Mountains raptor migration study in northern Utah is an ongoing effort to monitor longterm trends in populations of raptors using this northern Rocky Mountain migratory flyway. Raptors feed atop food pyramids, inhabit most ecosystems, occupy large home ranges, and are sensitive to environmental contamination and other human disturbances. Therefore, they serve as important biological indicators of ecosystem health (Cade et al. 1988; Bednarz et al. 1990a; Bildstein and Zalles 1995). For example, long-term migration counts in the eastern United States documented declines in several raptor species and helped us understand the deleterious effects of organochlorine pesticides (Spofford 1969, …

Microbial Colonization Of The Cloacae Of Nestling Tree Swallows, Tamara K. Mills, Michael P. Lombardo, Patrick A. Thorpe

Peer Reviewed Publications

Microbes have the potential to be important selective forces in many aspects of avian biology. Microbes can affect fitness as a result of either their pathogenic or beneficial effects on host health. Little is known about the chronology of microbial colonization of nestlings or the effects of microbes on fledgling condition. We set out to (1) characterize the time course of microbial colonization of the cloacae of nestling Tree Swallows (Tachycineta bicolor), (2) examine the relationship between cloacal microbes and fledgling condition, and (3) determine if nest mates had similar assemblages of cloacal microbes. We repeatedly measured nestlings …

Fall Field Report, August To November 1998, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

Larry Einemann kindly pointed out that in the Spring Report all his sightings from Pioneer's Park should have been attributed to Wilderness Park at Pioneer's Boulevard (in Lincoln). Larry noted that Pioneer's Park is a manicured Lincoln city park which is not good for birds except for in the vicinity of the embedded Chet Ager Nature Center. This was my (WRS) error; personally I have trouble even finding the Wilderness Park entrances, let alone naming them properly!

Another correction! John Sullivan pointed out that the 2 Summer Tanagers at Indian Cave SP on 10 August, 1997, were not his sighting. …

Parasitic Jaeger At Lake Mcconaughy, Stephen J. Dinsmore, W. Ross Silcock

Nebraska Bird Review

On 5 October, 1997, we joined Joel G. Jorgensen and John Sullivan for a pelagic trip on Lake McConaughy. A similar trip in late September 1996 yielded a Sabine's Gull, but we were really hoping to see a jaeger. From 7:00 to 8:30 a.m. we gradually worked our way from the dam towards the western end of the lake. Besides moderate numbers of Franklin's and Ring-billed Gulls, there were few birds on the lake. At approximately 8:45 a.m. Dinsmore noticed that all of the gulls at the western end of the lake had suddenly taken flight. Less than a minute …

Bird Banding Notes From Ruth Green, Ruth Green

Nebraska Bird Review

On 29 April 1998, while working with school children from the Chadron Public Schools, Ruth banded a Pine Siskin at Nebraska's Chadron State Park, Dawes County. Approximately seven and a half months later, on 12 December, this same bird was recovered beneath a feeder in Springfield, Oregon. The Pine Siskin was dead, perhaps a victim of disease sweeping the siskin population on the West Coast. This particular occurrence is noteworthy for the distance traveled both west and north.

The Summer Tanager pictured below was also banded by Betty. She banded the AHY-F (After Hatching Year, Female) Summer Tanager on 10 …

Endemicity And Regiona[L] Biodiversity In Nebraska's Breedin[G] Avifauna, Paul A. Johnsgard

Nebraska Bird Review

I estimate that 215 bird species currently breed or have previously bred in Nebraska. This number compares with a total of 330 species that breed or have bred in the Great Plains region south of Canada, as I defined that region in my book on the breeding birds of the Great Plains (Johnsgard, 1979).

Grasslands or potential grasslands make up about 81 percent of the Great Plains' vegetation, and probably represented about 96 percent of Nebraska's original vegetation. Only in the Sandhills region is that vegetation type still essentially intact; the tall-grass prairie of eastern Nebraska is Virtually gone. In …
