A New Subspecies Of The Free-Tailed Bat, Molossops Greenhalli, From Western Mexico (Mammalia: Chiroptera), J. Knox Jones Jr., Hugh H. Genoways
A New Subspecies Of The Free-Tailed Bat, Molossops Greenhalli, From Western Mexico (Mammalia: Chiroptera), J. Knox Jones Jr., Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
In June of 1964, field parties from the Museum of Natural History, the University of Kansas, collected two specimens of a unique free-tailed bat in Mexico, one in the state of Guerrero and the other in Oaxaca. These proved to be the first specimens of Molossops greenhalli taken outside of Trinidad and the first bats of the genus to be reported from north of Panama. Subsequently, Percy L. Clifton obtained, in the state of Jalisco, three more individuals of M. greenhalli, including the first male from the North American mainland.
Comparison with material from Trinidad indicates that the Mexican …
Eskimo Curlew Sighted
Nebraska Bird Review
When Craig Faanes, Grand Island, went to the Mormon Island Crane Meadows 16 April 1987 to watch Sandhill Cranes at night he saw a bird that he first took for a Whimbrel. He was familiar with Whimbrels on both coasts, but the more he studied the bird the more he was convinced that the bird was an Eskimo Curlew. After he had gone to the natural history museum at UNL and studied a stuffed Eskimo Curlew be was convinced that that was what he had seen. After the date of this sighting Eskimo Curlews were reported from "the Sabine and …

First Report Of The Nou Records Committee, Wayne J. Mollhoff
Nebraska Bird Review
Since this is the first report of the NOU Records Committee, perhaps a few words of background explanation are in order. I was named to establish a records committee at the annual meeting of the NOU in May 1985. At the fall field day in October 1985 I met with those people who had indicated a willingness to serve and was named chairman. I presented a draft set of by-laws, which we discussed, amended, and adopted. The committee membership and by-laws were approved by the NOU Board of Directors and ultimately published (NBR 54:72-74, ]986). Two of the main …

YELLOW RAILS. On 21 September 1986, while conducting a waterfowl survey on the Jack Senn WMA, near Ceresco, Lancaster Co., I flushed a small rail-like bird, which flew a short distance before landing in heavy grass. Although its flight was very similar to the Virginia Rail and the Sora, which I was accustomed to seeing, the light color and white wing patches were very distinctive. Later I checked a field guide and found that the description most closely matching this bird was that of the very secretive Yellow Rail.
I had planned to do some rail and snipe hunting the …

1987 Fall Field Day
Nebraska Bird Review
The weather was bright and clear for the 75 people who attended some part of the 1987 Fall Field Day at the 4-H Camp at Halsey National Forest 3 and 4 October. It was nice to have Mrs. Gross, who broke her leg at the Valentine meeting, among those attending. Her leg was progressing according to schedule, although she still used a crutch, There was the usual slide show Saturday night, the rest of the time was for birding, including banding. The Executive Board decided to have the terms of members of the Records Committee start and expire with the …

Early Fall Migration Of Sedge Wrens, Paul A. Bedell
Early Fall Migration Of Sedge Wrens, Paul A. Bedell
Nebraska Bird Review
Johnsgard (1980) lists the Sedge Wren (Cistothorus platensis) as an uncommon spring and fall migrant in eastern Nebraska, and a rare summer resident in eastern Nebraska, mostly east of a line from Knox to Gage counties. Half of the initial spring records occur between 1 and 12 May, with the latest 3 June. Half of the final fal1 records occur between 11 Sept. and 9 Oct., with the earliest 29 July. This paper presents observations of Sedge Wrens during 1987 in southcentral Nebraska, west of the line.
I found Sedge Wrens to be local1y common in grassy or …

A Nebraska Specimen Record Of Clark’S Grebe, Aechmophorus Clarkii (Lawrence), Thomas E. Labedz
Nebraska Bird Review
Clark’s Grebe, formerly known as light-phase Western Grebe (Aechmophorus occidentalis clarkii), was elevated to full species status (A. clarkii) in 1985 (American Ornithologists’ Union (AOU) 1983, 1985). This paper presents the first recorded occurrence in Nebraska of Clark’s Grebe and is documented with a specimen. Identification of Clark’s Grebe in the field is discussed, and a comparison is made of the Nebraska specimen with specimen s reported in recent literature.

Growth Performance For Four Breeds Of Swine: Crossbred Females And Purebred And Crossbred Boars, D. G. Mclaren, D. S. Buchanan, R. K. Johnson
Department of Animal Science: Faculty Publications
Purebred and two-breed cross (F1) boars were mated to F1 females to produce all possible three- and four-breed cross pigs involving the Duroc, Yorkshire, Landrace and Spotted breeds. Individual post-weaning average daily gain (ADG), age at 100 kg (AGE) and probed backfat thickness at 100 kg (BE) data were collected on 3,456 pigs. A total of 213 pens with an average of 15.58 pigs per pen was evaluated for post-weaning feed-to-gain ratio (F/G) and average daily feed consumption (ADF). Genotype x environment interactions, specifically breed x year-season farrowed and breed X parity (for ADG), were found to …

A Red-Naped Sapsucker In Sioux County, Nebraska, Mark A. Brogie, Ellen L. Brogie
Nebraska Bird Review
The Red-naped Sapsucker (Sphyrapicus nuchalis) has recently been recognized as a valid species (American Ornithologists' Union, 1985). Its inclusion in the avifauna of Nebraska is based on three birds, all taken in September in the northwestern corner of the state during the years 1919 and 1920 (Bray et al. 1986). Bray et al. (1985) give detailed accounts of these specimens and present an over-view of the species in Nebraska. The following, along with being the first spring record of the species in Nebraska, represents the first verified occurrence of this species in the state since 1920.

BLACK RAIL IN KNOX COUNTY. NEBRASKA
The Black Rail (Laterallus jamaicensis) is apparently an extremely rare spring and fall migrant in Nebraska (Johnsgard, 1980). No breeding evidence for this species exists for the state. although several field guides show Nebraska at the northern edge of this rail's breeding range. A description of a Black Rail seen 22 April 1980 in Lancaster Co. (NBR 48: 88 is the only accepted record (Class III) of this species in the state (Bray et al., 1986). Whitney et al., 1978) makes no mention of this species for South Dakota. although Iowa …

Insects In Some Nebraska Crops As Food For Pheasant Chicks, R. W. Whitmore, K. P. Pruess, R.E. Gold
Nebraska Bird Review
Insect biomass was estimated for crops grown on an organic, a dryland, and an irrigated farm from 1 June to 15 July, the time period assumed important for Ring-necked Pheasant (Phasianus colchicus) nesting and chick dependence on insect food. Differences due to farming system were not detected. Total insect biomass production during the season was 2,555, 2,173, and 338 mg per square m for oats-sweetclover, oats, and sweetclover, respectively. Leafhoppers were the most abundant insects in oats and oats-sweetclover, with plant bugs the most abundant in sweetclover. Mean standing crop biomass (mg per square m) of only those …

Macgillivray's Warbler In Cedar County, Nebraska, Mark A. Brogie, David A. Stage
Nebraska Bird Review
MacGillivray's Warbler (Oporornis tolmiei) is considered by Johnsgard (1980) to be a rare spring and fall migrant in western Nebraska. with most records from the Panhandle. but reported from as far east as Platte Co. Bray et al (1986) consider it regular and cite a specimen taken in Boone Co.. Whatever the status. this warbler is infrequently encountered in Nebraska. and separating this species from Mourning Warbler (Oporornis philadelphia) can often be difficult. Some authorities believe the two to be conspecific, although Hall (1979) found very few hybrid specimens and Salt (1973) found that they did …

PELICAN WITH SANDHILLS CRANES. On 17 October 1986, about 1:30 PM, I took a call from Mrs. Darrol Sukraw from Stapleton, who reported a flock of Sandhill Cranes (approximately 100 birds) that contained a single Whooping Crane. After questioning her about the description of the white bird, I felt her observation might be valid and asked her which direction the birds were traveling.
She informed me that the flock had just passed over Stapleton and was flying directly South down highway 83, toward North Platte. This is a distance of about 30 miles. Hoping that I could verify the Whooping …

Individual Heterosis And Breed Effects For Postweaning Performance And Carcass Traits In Four Breeds Of Swine, D. G. Mclaren, D. S. Buchanan, R. K. Johnson
Department of Animal Science: Faculty Publications
Individual heterosis and direct and maternal breed effects for postweaning average daily gain (ADG), off-test age (AGE) and probed backfat thickness (BF) were estimated from data on 1,664 pigs produced in a complete diallel mating system involving the Duroc, Yorkshire, Landrace and Spotted breeds. The same genetic parameters were estimated for various carcass traits by analyses of data collected on 269 barrow carcasses. Significant breed x environment (i.e., year-season farrowed, parity and sex) interactions were found for ADG, AGE and BF. Specific heterosis estimates for ADG and AGE were all highly significant and reasonably consistent among crosses. Overall heterosis for …

Karyotypic Analysis Of Five Rodents And A Marsupial From Belize, Central America, David W. Burton, John W. Bickham, Hugh H. Genoways, Timothy J. Mccarthy
University of Nebraska State Museum: Mammalogy Papers
Karyotypes and chromosomal banding patterns of six species of small mammals from Belize are presented and discussed in light of relevant data in the literature. Individuals of Heteromys desmarestianus had FN values of 72, which differs from previous reports. G-bands were obtained and compared to fluorescent bands (DAPI) and with the location of NOR sites. The karyotypes of Peromyscus mexicanus, Sigmodon hispidus, Oryzomys couesi, and Ototylomys phyllotis are identical to the karyotypes for these species described in the literature. Active NORs were located on four pairs of chromosomes in O. phyllotis and fluorescent bands obtained with the …
