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

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 …

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 …

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 …

A Development Plan For The South Coast Inshore Trawl Fishery, Fisheries Department Of Western Australia

Fisheries Management Papers

In March 1986 discussions were commenced between officers of the Fisheries Department and the Australian Fisheries Service concerning management measures for trawl fishery in the Great Australian Bight. These measures were considered necessary as a Western Australian Company (Toskel Fishing Co.) had commenced fishing the area. Given the excess fishing capacity in other Australian trawl fisheries it was considered advisable to institute management at an early stage and control development of this deep water fishery. Concurrent with these developments, mainly directed towards the control of larger trawlers in deeper waters, several small Western Australian trawlers operating out of Esperance and …

Lake Mead Prefertilization Study: Preliminary Nutrient Enhancement Studies In Lake Mead, Richard P. Axler, Larry J. Paulson, Patrick J. Sollberger, Donald H. Baepler, U.S. Bureau Of Reclamation

Publications (WR)

Studies conducted by the University of Nevada-Las Vegas (UNLV), the Nevada Department of Wildlife (NDOW), the Arizona Game and Fish Department (AGFD), The Nevada Division of Environmental Protection (NDEP), and the United States Bureau of Reclamation (USBR) have identified decreased algal production as a major factor involved in the decline of the Lake Mead sport fishery. Phosphorus-laden silt particles in the Colorado River have been sedimenting out in Lake Powell since the completion of Glen Canyon Dam 286 miles upstream in 1963. This sharp decrease in phosphorus loading to Lake Mead (>5000 tons per year) has resulted in decreased …

The Impact Of Weather On Kingbird Foraging Behavior, Michael T. Murphy

Biology Faculty Publications and Presentations

Foraging data on Eastern Kingbirds (Tyrannus tyrannus) were collected during the early breeding season in eastern Kansas to test the hypothesis that foraging rate and other aspects of foraging behavior vary with weather. Foraging characteristics of five additional kingbird species were also examined to assess Fitzpatrick's (1980) generalization that kingbirds (Tyrannus spp.) are aerial hawking specialists. In Eastern Kingbirds, total foraging rate was independent of air temperature, cloud cover, wind speed, and time of day, but the rate of aerial hawking varied directly with air temperature and inversely with cloud cover (both P < 0.05). Effects of the two variables were additive. The percentage of foraging movements that were aerial hawks also increased with temperature and declined with cloud cover, and, hover-gleaning and perch-to-ground sallying were observed mainly during cloudy weather. Sally (i.e., foraging flight) distance correlated directly with perch height and air temperature, and large insects were captured almost exclusively in long upward or horizontal flights. I interpret these data to indicate that foraging behavior and the capture of large, flying insects depends on weather because of how it affects the activity of insect prey. Foraging data on kingbirds support Fitzpatrick's generalization, but the relative use of aerial hawking varies considerably among species. Resident Tropical Kingbirds( T. melancholicus) are the most specialized foragers, whereas the migrant and widely distributed Eastern Kingbird appears to be the most generalized. Certain habitats also appear to favor the use of particular foraging methods (e.g., outward striking in grasslands and perch-to-ground sallying in drier, open habitats).

State Of The Fisheries Report 1986, Fisheries Department Of Western Australia

Status Reports of the Fisheries and Aquatic Resources

Western Australia continues to be one of the leading fishing States in Australia. The total gross value of fish, crustaceans and molluscs for 1985/86 was $139 million (Table 1) to which may be added the value of the pearl culture industry resulting in a total value of approximately $180 million.

Genic Population Structure And Gene Flow In The Northern Flicker (Colaptes Auratus) Hybrid Zone, Thaddeus A. Grudzien, William S. Moore, J. Richard Cook, Danilo Tagle

Biological Sciences Faculty Research Publications

The Yellow-shafted Flicker (Colaptes auratus auratus) and Red-shafted Flicker (C. a. cafer) form a stable, narrow hybrid zone on the western Great Plains of North America. Allozyme data were obtained from 31 structural gene loci for 33 samples representing 246 Northern Flickers from throughout the Great Plains. Flickers were approximately equivalent to other birds in terms of proportion of polymorphic loci (P = 0.207) and average heterozygosity (H = 0.056). There was no concordant variation between plumage characters and allelic frequencies.

Gene-diversity analysis indicated that 92.5% of the genic variation occurred as within-deme heterozygosity ( …

Thermal Tolerances And Preferences Of Fishes Of The Virgin River System (Utah, Arizona, Nevada), James E. Deacon, Paul B. Schumann, Edward L. Stuenkel

Publications (WR)

Critical thermal maxima (CTM) and thermal preferenda of the common fishes of the Virgin River were examined. Differences in final temperature preferenda and CTM for species with low thermal lability (speckled dace, spinedace, roundtail chub) correspond well with differences in their distribution and abundance in the river. These species shifted their acute thermal preferences relatively little as acclimation temperature increased. For thermally labile species (woundfin, red shiner, desert sucker, and fiannehnouth sucker), the final preferendum is a less precise indicator of probable distribution. The woundfin, an endangered fish, has a high CTM (39.5 C at 25 C acclimation) and a …

Use Of Woody Vegetation By Beavers In Southeastern Virginia, John L. Echternach, Robert K. Rose

Biological Sciences Faculty Publications

Nonbreeding and sometimes transient beavers, Castor canadensis, cut a variety of woody plants throughout the year during a 15-month study at three sites in southeastern Virginia. Ten species of trees were cut in proportions greater than would be expected according to their availabilities. Beavers heavily used viburnum, alder, ironwood, bayberry, tulip poplar, and dogwood. Winter food caches were constructed but were only lightly used.

Report Of The Rock Lobster Industry Advisory Committee To The Hon. Minister For Fisheries., Rock Lobster Industry Advisory Committee

Fisheries Management Papers

The Committee recognises that the exploitation rate on the rock lobster stocks is very high and that this factor is a major importance in formulating the advice on management measures. However, the Committee also recognises the high level of capital investment in the industry and that any recommendation which leads to a significant change in the management rules is likely to have a far reaching effect on many of the participants. Accordingly, the Committee endeavours to reduce to a minimum the year to year changes in the management rules. When changes are required the Committee places considerable weight on matters …
