The NOU count during Fall Field Days 27-28 September 1996 was centered at the Nebraska National Forest (NNF) , which is mostly in Thomas County, and also included Thomas outside the forest and three other counties: Cherry, Brown, and Blaine (see Table 1). The total number of species was 116 compared to 103 for the same area about 10 days later in 1995. Twelve species seen in 1995 were absent in 1996, and 22 species seen in 1996 were absent in 1995.

Spring Field Report, March-May 1997, W. Ross Silcock

Nebraska Bird Review

First a correction: in the Fall Seasonal Report (NBR 63:101) the account on Whooping Crane listed 2 reports 25 November; these should have been 25 October.

This report includes observations, designated (B), reported to the Nebraska Birdline (402-292-5325), operated by Loren and Babs Padelford. While these are anonymous submissions, many are reported to us subsequently by the original observers; those which are not but are significant but unsubstantiated, are indicated herein as such by a phrase like "no details submitted". We have also used this phrase for other unsubstantiated reports herein. Hopefully, observers involved will send us a few …

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 …

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 …

"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 …

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

Eric K. Bollinger

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.
