Book Review: "Swallow Summer" By Charles R. Brown, Linda R. Brown

Nebraska Bird Review

Swallow Summer is a first-person, day-to-day account of Charles and Mary Bomberger Browns' fourteenth field season studying Cliff Swallows in western Nebraska. This story also concerns the three bright undergraduate field assistants who shared the experience of the summer of 1995. Charles communicates their discoveries of Cliff Swallow colony behavior in an everyday conversational manner. It was easy for me to catch the excitement they feel in "discovering the questions." I felt their wonder when as this very cold late breeding season slowly progressed, these researchers discovered that indeed many of the swallows were not breeding at all. This rather …

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 …

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 …

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 …

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 …

Cooperative Whooping Crane Tracking Project (August 1998-January 1999)

Nebraska Bird Review

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.

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, …

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 …

The Age Of Birds In Nebraska, Paul A. Johnsgard

Papers in Ornithology

If each mile of highway I-80 in Nebraska represented a million years of natural history, then the 450 miles from the 60th St. on-ramp in Omaha to the westernmost exit at the Wyoming border would represent the 450 million years that encompass the time that evidence of life has been found on earth. The earth itself is more than four billion years old, or ten times older than the time scale of life described here.
The 450 million years of life on earth are correlated to the distance from Omaha to the Wyoming border, and the flora and fauna of …

The Relative Importance Of Patch Area And Perimeter–Area Ratio To Grassland Breeding Birds, Christopher J. Helzer, Dennis E. Jelinski

School of Natural Resources: Faculty Publications

Habitat fragmentation has been implicated as a major cause of population decline in grassland birds. We tested the hypothesis that a combination of area and shape determines the use of grassland patches by breeding birds. We compared both species richness and individual species presence in 45 wet meadow grasslands in the floodplain of the central Platte River, Nebraska. Bird data were collected through the use of belt transects and supplemented by walking and listening outside transects. Our data supported our primary hypothesis that perimeter–area ratio, which reflects both the area and shape of a patch, is the strongest predictor of …

Plant And Breeding Bird Communities Of Black-Tailed Prairie Dog Colonies And Non-Colonized Areas In Southwest Kansas And Southeast Colorado, Stephen L. Winter

School of Natural Resources: Dissertations, Theses, and Student Research

This research was initiated to determine if plant and bird communities on black-tailed prairie dog (Cynomys ludovicianus Ord) colonies in southwest Kansas and southeast Colorado differed from those found on associated non-colonized areas. Vegetation height and density, and the cover and frequency of numerous plant species differed between prairie dog colonies and non-colonized areas that were co-dominated by mid-height grasses and shortgrasses. A comparison of prairie dog colonies with non-colonized areas that were dominated solely by shortgrasses did not reveal a difference in vegetation height and density. The number of species that differed in cover or frequency between prairie dog …

The Effect Of Proximity On Landmark Use In Clark’S Nutcrackers, Kristy L. Gould-Beierle, Alan Kamil

Avian Cognition Papers

Clark’s nutcrackers, Nucifraga columbiana, store thousands of pine seeds during the autumn and retrieve them throughout the winter. It has been shown that these birds are able to use visual cues to relocate hidden food in the laboratory. In this set of experiments, we trained three groups of Clark’s nutcrackers to find a hidden food goal that was placed in the same spatial location relative to the testing room. During training, the location of two local cues in relation to the goal differed between the three groups. Group 1 learned the task with the cues closest to the goal, group …

Patterns Of Movement And Orientation During Caching And Recovery By Clark’S Nutcrackers, Nucifraga Columbiana, Alan Kamil, Russell P. Balda, Sally Good

Avian Cognition Papers

Clark’s nutcrackers regularly store large numbers of pine seeds and remember the locations of the cached seeds. Although they are very accurate, they do make some errors during recovery. In an attempt to determine whether any behaviours during caching predicted the occurrence of errors during recovery, we videotaped Clark’s nutcrackers while they cached and recovered seeds under laboratory conditions. We used the videotapes to develop complete, quantitative descriptions of caching and recovery behaviour, with an emphasis on body orientation and directions of movement. During caching, the birds showed the greatest change in their orientation and direction following cache creation. During …

How Do They, Indeed? A Reply To Biegler Et Al., Alan Kamil, Juli E. Jones

Avian Cognition Papers

We trained Clark’s nutcrackers, Nucifraga columbiana, to search halfway between two landmarks while varying the distance between the landmarks (Kamil & Jones 1997). We found that the birds learned the problem readily and generalized to novel interlandmark distances within the range of distances used during training. Unlike some other studies in which responses to proportional distance were obtained (e.g. O’Keefe & Burgess 1996; Tommasi et al. 1997), the nutcrackers showed very precise search and maintained this precision during the transfer test. The distributions of digging locations around the central position were concentrated within ±1–2 cm of the central location …
