A Probable Nesting Of Clark's Nutcracker (Nucifraga Columbiana) In Nebraska,, Wayne Mollhoff

Nebraska Bird Review

This report provides details on the probable nesting of Clark's Nutcracker (Nucifraga columbiana) in Morrill, Scotts Bluff Co., Nebraska, in 1997. It also corrects an erroneous report of nesting in the Pine Ridge area of Nebraska (Silcock & Jorgensen 1997b).

A single Clark's Nutcracker was first noted corning to a suet feeder at the home of Ms. Edna C. Thomas in Morrill 8-9 Jan 1997. It came to the feeder at least weekly and was often seen daily. A second Clark's Nutcracker appeared during the second week of Feb. Initially, the bird already present was antagonistic towards it …

Black-Throated Sparrow Banded In Omaha, Nebraska, Ruth C. Green

Nebraska Bird Review

On 20 December 1997, I banded a Black-throated Sparrow in the vicinity of 43rd and J Streets in South Omaha, Nebraska. The band number on this bird is 2120/83856. It was an AHY-Male and, according to the description given by James D. Rising in his book, A Guide to the Identification and Natural History of the Sparrows of the United States and Canada, it was of the subspecies Amphispiza b. bilineata. This is the smallest of the three races found in the united States and it is indigenous to central Texas. Besides the smaller size, the identifying field …

Fall Field Report, August-November 1997, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

Notable this Fall was very heavy coverage of the Panhandle during Sep-Oct, which yielded several outstanding records (all, of course, pending NOURC approval). Incredible were first Panhandle records of Golden-winged, Chestnut-sided, Bay-breasted, and Prothonotary Warblers, 3rd record of Northern Waterthrush, and 4th record of Blackburnian Warbler. Philadelphia Vireo was found in the Panhandle for the 3rd time. Important also were 3 records of Hammond's Flycatcher, the 3rd-6th for the state, and likely a regular migrant, and 5 of Cassin's vireo, previously known only by 2 specimens. Finally, from the Panhandle, 4 reports of Blue-Gray Gnatcatcher may be changing the status …

Nebraska Bird Review

EDITOR'S COMMENTS

This issue is the last of my six-year term as Editor of The Nebraska Bird Review. It has been a challenging and stimulating experience, and I have learned much about bird lore and publishing methods. My workload was lightened considerably when Ross Silcock took on the seasonal field reports in 1994, assisted initially by Richard C. Rosche and recently by Joel G. Jorgensen. Dr. R. G. (Rusty) Cortelyou volunteered to compile the index for each volume during my term. This is a time-consuming and detailed project, and I sincerely appreciate his contribution.

I am very pleased that Dr. …

Notes On The Nesting Biology Of Pygmy Nuthatches In Nebraska, Wayne Mollhoff

Nebraska Bird Review

Introduction

Pygmy Nuthatches (Sitta pygmaea) were considered to be no more than casual or rare winter visitors to the northwest part of Nebraska by previous investigators (Bruner et al. 1904; Swenk 1918; Haecker et al. 1945; Rapp et al. 1958, 1971). I. S. Trostler's earlier comment that the species was "a rare resident, breeds in Omaha" (Bruner 1896) was later felt to be in error, as evidenced by Bruner's later comment that it was, "A fall and winter visitor . . . not breeding in the state" (Bruner et al. 1904).

The first evidence of breeding was the …

Whooping Crane Sightings, August 1997-January 1998, Steven Anschutz

Nebraska Bird Review

Cooperation throughout the Whooping Crane flyway continues to be excellent, and special thanks go out to each participant. Between 1977 and 1988, 132 juvenile birds were color-marked on the breeding grounds, and 40 were accounted for during the winter of 1997-98. Fourteen color-marked Whooping Cranes were observed during the fall migration. All sightings of color-marked birds are maintained at the Grand Island office. The importance of observers looking closely for the colored leg bands cannot be overemphasized.

Based on observations of the breeding grounds during the summer of 1997, about 192 Whooping Cranes were expected to arrive at the Aransas …

Egg Removal By Brown-Headed Cowbirds: A Field Test Of The Host Incubation Efficiency Hypothesis, Douglas R. Wood, Eric K. Bollinger

Eric K. Bollinger

Brown-headed Cowbirds (Molothrus ater) often remove host eggs, usually to the detriment of the host's reproductive success. We tested the hypothesis that host egg size and number influence the incubation efficiency of a parasitic egg. A single House Sparrow (Passer domesticus) or Brown-headed Cowbird egg was placed in each host nest (addition), and in some nests a host egg was removed as well (addition/removal). Hatching success and incubation length were measured to determine whether host-egg removal conferred an advantage in incubation efficiency compared to simple addition of a parasitic egg. Redwinged Blackbirds (Agelaius phoeniceus) and Chipping Sparrows (Spizella passerina) served …

1996 (Eighth) Report Of The Nou Records Committee, Mark A. Brogie

Nebraska Bird Review

The functions and methods of the NOU Records Committee are described in its bylaws (NOU Records Committee 1986). 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. THE OFFICIAL LIST OF THE BIRDS OF NEBRASKA was first published in 1988 (NOU Records Committee 1988) and has been appended six times (Mollhoff 1989, Grenon 1990, 1991, Gubanyi l996a, 1996b, 1996c). An update of THE OFFICIAL LIST OF THE BIRDS OF NEBRASKA was last published in 1997 (NOU Records Committee 1997) and includes the additions and changes …

Notes On Bird Sightings In Nebraska, L. Iola Pennington

Nebraska Bird Review

1997 Report for Wauneta area, Chase County. I have seen 49 species, including 20 Turkey Vultures, many Wild Turkeys, a covey of Northern Bobwhite near my house, a Ruby-throated Hummingbird in my garden flowers such as Gilia, and a Black-headed Grosbeak—a first for my acreage. On 6 September, a male Northern Cardinal brought two young to one of the seven water pans I keep for birds and animals. Other species listed in the area: Great Blue Heron, Gadwall, American Kestrel, Ring-necked Pheasant, Killdeer, Rock Dove, Mourning Dove, Yellow-billed Cuckoo, Common Nighthawk, Chimney Swift, Belted Kingfisher, Red-headed Woodpecker, Hairy Woodpecker, …

Mountain Plover Nest In Kimball County, Stephen J. Dinsmore

Nebraska Bird Review

On 18 May 1995 I observed two adult Mountain Plovers 5 mi west and 1.25 mi north of Bushnell in southwest Kimball county. The birds were in an area of short-grass prairie interspersed with clumps of prickly pear and bare ground. I observed both birds almost continuously from 1-2 p.m. MDT. The first bird was along the road south of the fenceline, just after the road climbs on top of the plateau. The second bird was about 0.1 mi to the north on the west side of the road. Both birds were medium-sized, plain shorebirds, similar in shape and posture …

Whooping Crane Sightings During March-May 1997 Migration, Steven Anschutz

Nebraska Bird Review

During the 1996-97 winter, 158 (143 adult/subadult and 15 juvenile) Whooping Cranes stayed at the Aransas National Wildlife Refuge in Texas. Two early migrants in Nebraska were an adult-plumaged bird first observed on 9 March, and a juvenile confirmed on 19 March. Neither of these birds wintered at Aransas, so the total population was therefore 160 (144 adult/subadult and 16 juvenile). All 158 cranes wintering at Aransas were present 3 April, but by 10 April, about 103 cranes had begun to migrate, and by 24 April, only 13 cranes were still at Aransas. All cranes had migrated by 6 May.

Summer Field Report, June-July 1997, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

A couple of preliminary notes: in the accounts below we have noted for several species "Reports were routine." This means that these species, mostly common in occurrence, were indeed present and reported, but the reports did not include unusual arrival or departure dates or high counts. For this Summer Report, observers are encouraged to report high counts on their BBS routes, as well as nesting data such as egg and fledging dates. Finally, this report includes a few observations from 1996.

In general, this was a rather routine summer period. The only real rarity was, however, a good one, a …

Shorebird Migration In The Eastern Rainwater Basin—Spring 1997, Joel G. Jorgensen

Nebraska Bird Review

The Rainwater Basin is arguably Nebraska's most productive area for observing migrant shorebirds, especially in spring. After several years of irregular shorebirding in the region, in 1997 I decided to perform regular shorebird censuses in the eastern portion of the RWB (eRWB).

Spring 1997 Bird Counts During Tristate Meeting, And For North Platte-Lincoln County, Nebraska

Nebraska Bird Review

The Ornithologists' Unions of Iowa, Nebraska, and South Dakota held a Tristate spring meeting at Sioux City, IA on 16-18 May, organized by Bill Huser and committee members from Iowa and South Dakota, and hosted by the Loess Hills Audubon Society from South Sioux City, NE. Field trips were made into nearby areas of all three states. During an indoor session, a paper on "Migrating Hawks along Iowa's Loess Hills" was presented by Loren and Babs Padelford. The banquet speaker was Ken Kaufman, who spoke on "Bird study and natural history in the 21st century." During the weekend, a total …

Remembering Doris Gates, A Great Teacher, Mark M. Peyton

Nebraska Bird Review

Doris Gates (1915-1983) taught Biology at Huntley, NE from 1938-1941, North Platte from 1941-1955, and Chadron State College from 1955-1974. She lived until her death at the foot of "Rush No More Butte" south of Chadron, was a member of the North Platte Tout Bird Club, and served as President of the Nebraska Ornithologists' Union and Editor of The Nebraska Bird Review.

Doris included plants and birds in her lectures on Biology, but she taught much more than that because she understood the beauty of life. She believed that beauty was in what you did rather than what you looked …

International Shorebird Survey Report For Southeastern Nebraska—Spring 1997, Kevin Poague, John Dinan

Nebraska Bird Review

In 1974, Manomet Observatory in Massachusetts organized the International Shorebird Survey (ISS) to collect information on shorebirds during migration. The project is intended to monitor shorebird population trends and to identify major migration routes, timing, and locations of staging areas. More than 600 contributors from 38 states of the United States, and countries, territories, and commonwealths throughout the hemisphere have contributed data since the program's inception. The Nebraska Game and Parks Commission collected data for the ISS in the eastern Rainwater Basin area (Clay, Fillmore, York, and Seward counties) from 1993-1996.

Two Hybrid Diving Ducks At Cunningham Lake, Douglas County, Joel G. Jorgensen

Nebraska Bird Review

During the spring of 1997 I had the opportunity to observe and study two apparent hybrid diving ducks at Glenn Cunningham Lake, Douglas County. Both birds appeared to be mature males in breeding plumage. One bird was a suspected Redhead x Canvasback hybrid and the other was a suspected Common Goldeneye x Hooded Merganser hybrid. Sibley (1994) states that both hybrid combinations occur "occasionally."

The Lake Ogallala State Recreation Area (LOSRA) is located immediately downstream from Lake McConaughy, which was formed by the construction of Kingsley Dam across the North Platte River, and includes riparian woodland, shrubland, grassland, marsh, sandbeach, rivers, ponds, and lakes. Birds were surveyed in LOSRA from 1988 to 1992 and censused in the southwest campground of LOSRA from late May to mid-July during the 1991 and 1992 breeding seasons. Seventy-five bird species (56 terrestrial and 19 aquatic) were observed, including several hybridizing species. Thirty-one terrestrial species inhabited the southwest campground, but only 60% of these were counted during biweekly censuses; …

Red-Necked Grebe At Sutherland Reservoir, Stephen J. Dinsmore, Joel G. Jorgensen

Nebraska Bird Review

On 26 September 1996, we saw and photographed a Red-necked Grebe at Sutherland Reservoir in Lincoln County. When we arrived at the northwest end of the lake, Dinsmore noticed a slightly smaller, bigger-headed grebe resting with a couple of Western Grebes. Both of us immediately recognized the bird as a Red-necked grebe. We studied it at close range from 2:43-3:17 p.m. CST. Compared to a Western Grebe, in addition to the size differences mentioned above, this bird was shorter-necked. The mantle was dark gray with some brown flecking. The flanks were grayish. The foreneck was very buffy, almost reddish in …

A George Miksch Sutton Bibliography, Paul A. Johnsgard

Nebraska Bird Review

Members of the Nebraska ornithologists' Union often do not realize that the reason a George Miksch Sutton sketch of a burrowing owl is used as the logo of our organization, and also appears on the cover of every issue of The Nebraska Bird Review, is because Dr. Sutton was a native Nebraskan. He was born in Bethany (now part of northeastern Lincoln) in 1898, and several years of his childhood were spent there before the family left the state permanently. In spite of Dr. Sutton's great influence on American ornithology and bird art, no bibliography of his writings has …
