John Dinan, Nongame Bird Program Manager, Nebraska Game and Parks Commission, 2200 N. 33rd st., P.O. Box 30370, Lincoln, NE 68503-0370 (phone: 402/471-0641; Fax: 402/471-5528), supplied the results of the 1997 (January 1-15) Bald and Golden Eagle surveys, with six organizations and twelve individuals participating.

Conditions for 1997 survey: Temperatures ranged from 8 to 35°F. The Niobrara River had 50-100% ice cover except the upper portion, which was mostly open. The unchannelized portion of the Missouri River was 90-100% ice-covered, but the channelized portion was open and was carrying floating ice below Tekamah. The Platte River had 50-90% ice …

Notes On Bird Sightings In Nebraska March 1997, Ruth C. Green, Alice Kenitz, Joel G. Jorgensen, Stephen J. Dinsmore

Nebraska Bird Review

Albino Eastern Bluebirds. On 24 July 1996, I banded two totally white Eastern Bluebirds in Sarpy County, Nebraska. These two birds were in a nest with two other normally plumaged siblings. They were not only white-plumaged, their feet and bills were white and the eyes were a pinkish-red. They were just as well developed as the two normal birds and were ready to fledge, which they did the following day.

I believe these birds fit the description of total albinism as defined by John K. Terres in The Audubon Encyclopedia of North American Birds. He defines total albinism …

Bald Eagle Counts At Two Central Nebraska Public Power And Irrigation District Facilities, Mark M. Peyton, Rodger Knaggs

Nebraska Bird Review

Since 1988, the Central Nebraska Public Power and Irrigation District (Central) has provided free access to the public at its Johnson #2 (J-2) Hydroelectric Plant south of Lexington, Dawson County, and the use of spotting scopes and binoculars to view Bald Eagles foraging and perching along the tailrace of the plant. Central also provided a small trailer from 1990-95 for viewing Bald Eagles near the outlet of the Kingsley Hydroelectric Plant at Lake Ogallala in Keith County. In 1996, Central completed construction of a permanent viewing facility at this location. Central provides personnel at both locations to answer questions and …

"The Official List Of The Birds Of Nebraska, Joseph A. Gubanyi

Nebraska Bird Review

The Official List of the Birds of Nebraska was last published in 1988 (NOU Records Committee 1988). That list included 406 species whose occurrence in Nebraska had been documented to the satisfaction of the NOU Records Committee at that time, following the sequence and nomenclature as outlined by the American ornithologists' Union (1983, 1985, 1987). The present list includes 427 species based on all changes to the Official List of the Birds of Nebraska as determined by the NOU Records Committee (Mollhoff 1989; Grenon 1990,1991; Gubanyi 1996a, 1996b, 1997; Brogie 1997), as well as sequence and taxonomic changes made by …

Winter Field Report, December 1996-February 1997, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

First, we wish to thank Larry Malone (LKM) for his excellent and detailed reports over the last 3 years or so. The reporting from western Nebraska has been greatly enhanced through Larry's efforts. Larry has retired from his position as Superintendent of NPNWR and CLNWR and we wish him luck.

Interesting features of this winter report include a few rarities such as Barrow's Goldeneye, Greater Yellowlegs, Mew Gull, Great Black-backed Gull, Inca Dove, a “montane invasion” of such species as Steller's Jay, Clark's Nutcracker, Mountain Chickadee, Bohemian Waxwing, Gray-crowned Rosy-finch, and Cassin's Finch, birds rare in midwinter such as Red-breasted …

Explanations For The Infrequent Cowbird Parasitism On Common Grackles, Brian D. Peer, Eric K. Bollinger

Faculty Research & Creative Activity

We determined the factors responsible for the lack of parasitism on Common Grackles (Quiscalus quiscula) by Brown-headed Cowbirds (Molothrus ater). We found no evidence of parasitism on the 401 grackle nests we monitored in east-central Illinois. By the time cowbirds began laying eggs, 88.5% of all grackle nests were beyond the point of successful parasitism. Grackles rejected cowbird eggs more frequently during the prelaying stage of the nesting cycle (38.2%) compared to later stages (12.3%). Thirty-three cowbird eggs and nestlings were cross-fostered into grackle nests. Data were collected on 15 cowbird nestlings, of which three fledged. The cross-fostered cowbird eggs …

Eyespray Vaccination: Infectivity And Development Of Immunity To Eimeria Acervulina And Eimeria Tenella, H. David Chapman, Tim E. Cherry

Faculty Publications

The infectivity of a coccidiosis vaccine and its ability to immunize chickens against two species of Eimeria was examined. The vaccine was administered to newly-hatched chicks by spraying directly onto the eye. The method resulted in a high proportion of chicks infected with E. acervulina and E. tenella. Vaccinated birds reared in cages in the absence of reinfection did not develop immunity to either species by 4 wk of age, but birds reared in floor pens developed immunity to both E. acervulina and E. tenella.

Whooping Crane Sightings, August-December 1996, Steven Anschutz

Nebraska Bird Review

Based on observations of the breeding grounds during the summer of 1996, about 170 Whooping Cranes were expected to arrive at the Aransas National Wildlife Refuge in Texas during the fall. The first arrival (two birds) was confirmed on 23 October. A total of 158 birds (143 adults/subadults and 15 young) were wintering at Aransas 1996-97. As of 16 January 1997, six adults and eight subadults, of the number anticipated, had not arrived at the refuge.

The first recorded dates for confirmed observations of migrating Whooping Cranes were 2 August in Canada and 22 September in the United States. The …

Nebraska Bird Review

This book contains 18 essays based on observations Miss Sherman made on a farm in northeastern Iowa six miles west of the Mississippi River, near McGregor. The essays were given at meetings of scientific societies (she belonged to 15) or were published in their journals, and included such titles as "Feeding Winter Birds" and "Experiments in Feeding Hummingbirds During Seven Summers." She was recognized for her knowledge of birds, and her forceful and pungent wit.

Miss Sherman was born on the Iowa farm in 1853 and died there in 1943. She was an artist and teacher for the first 20 …

Fall Field Report, August-November 1996, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

This fall we received numerous excellent reports from which to compile this summary. Most parts of the state are covered, except the southwest and north central, although many observers at least pass through those areas. A note about details on unusual observations. The new NOU Field Card, which can be ordered by sending a stamped, self-addressed envelope to the NOU Librarian, Univ of Nebraska State Museum, Lincoln, NE 68588-0514, indicates species that need complete documentations, mostly casual and accidental species. However, we realize that information about early and late migration dates, and rarity in the west or east is not …

Nebraska Bird Review

House Finches. This species has been appearing at my backyard feeders, 10 to 30 feet from our window, for several years, increasing in number each year. They came nearly every day in 1996 except during a period that I associate with post-breeding molt. Numbers varied from one to a maximum of 17 at one time, with 11 counted for the 1996 Christmas Bird Count. We commonly use 7-8 power binoculars to look for a rare Purple Finch. House Finches are noticeably smaller than House Sparrows and slightly larger than American Goldfinches, and feed with both species.

Males have varied in …

Nebraska Ornithologists' Union Annual Meeting 18 May 1996, Robin Harding

Nebraska Bird Review

The 1997 Annual Meeting will be held jointly with the South Dakota and Iowa Ornithologists' Unions in South Sioux City, NE 16-18 May.

Neal Ratzlaff, President, reported on several items. Funds are being sought to publish the Breeding Bird Atlas for Nebraska. The new NOU Field Cards of Nebraska Birds are ready for distribution. The Wildlife Diversity Funding Initiative is on hold because some companies are afraid of increasing their prices. NOU members were encouraged to urge Cabela's to support the Initiative.

A Review Of The Status Of Limnodromus Griseus, The Short-Billed Dowitcher, In Nebraska, Joel Jorgensen

Nebraska Bird Review

The two North American dowitchers are notoriously difficult to distinguish from each other. This is not only true of field observations, but there are several instances where a specimen identified as one species was found to be the other upon review. Limnodromus scolopaceus, the Long-billed Dowitcher, has always been considered the common dowitcher in Nebraska, while Limnodromus griseus, the Short-billed Dowitcher, is less common. Confusion about identification and the lack of consistent, well-documented records have caused the status of L. griseus in Nebraska to be a matter of speculation.

Taxonomy of dowitchers was for some time confused. Studies …

Another Common Crane In Nebraska With A Summary Of North American Records, Gary Lingle

Nebraska Bird Review

On 30 March 1996 around 1000 h CST, Bob Janssen and Jim Williams of Minnetonka, Minnesota, discovered a Common Crane (Grus grus) feeding in corn stubble with a flock of Sandhill Cranes (Grus canadensis) in Section 34 T9R10 Hall County, Nebraska. The Commom Crane associated with the Sandhill Cranes, which were at peak numbers in the Platte River valley. Later that day, several observers, including myself, witnessed the bird in section 32 about 500 yards away, where it mingled with a few hundred Sandhill Cranes. The difficulty in seeing this bird was illustrated by the fact …

A Late Baird's Sandpiper In Keith County, Stephen J. Dinsmore

Nebraska Bird Review

On 23 December 1994, Gordon Brown and I were walking the North Platte River below Keystone Dam as part of the Lake McConaughy Christmas Bird Count (CBC). At approximately 8:30 a.m. MST, about 0.5 mi below the dam, we observed a group of 8 Killdeer and a smaller shorebird, which we immediately recognized as a "peep." We studied the bird for about 30 minutes at distances as close as 40 feet and then returned in the afternoon to photograph it. The size and black legs immediately eliminated Least Sandpiper, and the dark rump eliminated White-rumped Sandpiper. The remaining possibilities were …

Spring Field Report, March-May 1996, W. Ross Silcock

Nebraska Bird Review

This was an interesting spring season, with something for everyone. Interesting data in terms of numbers are being produced by the North American Migration Count (NAMC), especially this spring in Sarpy County; examples are 499 Swainson's Thrushes, 76 Gray-cheeked Thrushes, and 118 Black-and-white Warblers, and others. Some species appeared in large numbers such as 5,000 Western Grebes, 16 Clark's Grebes, 10,000 Wilson's Phalaropes, 300 each of Black-bellied Plover and Sanderling, 54 Whimbrels, and two flocks of over 100 Great-tailed Grackles.

Some interesting early and late dates are included in the species accounts, but several observers noted unexpected species such as …
