Agricultural Bird Problems In The West, Donald Balser

Bird Control Seminars Proceedings

First, I'd like to qualify geographically, the area where most of our work is done and problems occur. It is primarily in the Rocky Mountain states and the west coast. While the area of the Denver Wildlife Research Center's responsibility covers the states west of the Mississippi River; the only area on the plains where our personnel have conducted intensive studies outside of Colorado is in South Dakota. The major bird problems in grain crops in the west are primarily caused by blackbirds excepting, of course, waterfowl depredations. It's difficult to rank the principal crops according to seriousness of losses. …

Agricultural Bird Problems In The Southeast, James Caslick

Bird Control Seminars Proceedings

Our chairman has wisely asked that we not spend all of our time here telling each other about our bird problems. In the Southeast, our difficulties with blackbirds are based upon the same bird habits that cause trouble elsewhere: they flock, they roost and they eat, generally taking advantage of the readily available handouts that today's agricul¬tural practices provide. Those of us on the receiving end of these de¬predations of course think that damage in our own particular area must be far the worst, anywhere. Because of the location of our meeting place today, perhaps it is worthwhile to point …

Population Dynamics Of Pest Birds, Robert Mclean

Bird Control Seminars Proceedings

We want to talk now about population principles; this is our main problem dealing with populations. We should discuss the general application of population principles and the management of bird populations. The reason we can discuss this is because many species follow established principles; population growth and later regulation of its size follow certain basic rules. Many pest species follow these principles, but not always to the letter. Populations of different species, as well as of a species, vary depending upon local conditions. Local environments dictate what population levels and the growth of populations will be. Minor variabilities still fit …

Ecological Control Of Bird Hazard To Aircraft, V. E. F. Solman

Bird Control Seminars Proceedings

The Canadian Wildlife Service has had twenty-five years experience with the problem caused by bird contacts with aircraft. I experienced my first bird strike, while flying as an observer on a waterfowl survey in August, 1940. Officers of the Service investigated bird problems at airports at Yarmouth, Nova Scotia, and Cartierville, Quebec, in the late 1940's. Those incidents involving gulls and low speed piston-engined aircraft caused minor damage to the aircraft but considerable disturbance to the operators. As aircraft speeds increased and airports became more numerous and busier the problem increased in extent and complexity. By 1960 it was apparent …

Control Of Birds In The Airport Environment, C. E. Faulkner

Bird Control Seminars Proceedings

We now move from the inside of the hangar to the outside and view the problem of birds on runways and taxiways. The increased use of aircraft for transportation and the increased use of jet aircraft to take care of this transportation will, of course, compound our bird problems at major airports. To lesson this probability of the bird-aircraft strike, bird management plans should be initiated at these var¬ious commercial airports so we can lessen the bird problem. To show you some of the mechanics involved in a bird management plan, I'm going to take you to a typical airport …

Side Effects Of Persistent Toxicants, George J. Wallace

Bird Control Seminars Proceedings

As you can see from the general tenor of the printed program for this seminar, I am in the unenviable position of trying to discourage you from certain types of chemical control; but my assigned topic "Side Effects of Persistent Toxicants," implies that mission. However, my remarks may be somewhat anticlimax at this time, because it is now generally conceded that we need to reevaluate certain chemicals in control work and to restrict or severely curtail use of those that per¬sist for long periods in the environment. So let me detail my reasons for a somewhat negative attitude toward the …

Deer And The Ainsworth Canal, Karl E. Menzel

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Merritt Dam and the Ainsworth Canal were constructed by the Bureau of Reclamation to provide irrigation water for the vicinity of Ainsworth in north central Nebraska. The reservoir was completed in 1964 and at capacity has an area of 2,906 surface acres. The canal commences at the Dam, 27 miles southwest of Valentine, and extends eastward for 52.8 miles to Highway 20 east of Johnstown. The canal, along with 174 miles of laterals and 63 miles of drains, serves to irrigate about 34,000 acres of farmland.

The Ainsworth Canal is lined with concrete along its entire length. In the western …

Effect Of Artificial Insemination On Frequency Of Undesirable Recessive Genes, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Reduction in the frequency of' undesirable recessive genes is examined for several combinations of initial gene frequencies and number of offspring obtained by random mating of young sires to the population. Only sires not having affected offspring are then returned to heavy use. Such selection can very rapidly reduce the number of affected offspring, if the initial gene frequency is high or if the number of tested offspring is 200-500 for lower gene frequencies. For some combinations, frequency of affected offspring in the population is higher after two or three generations of selection than in the first generation of selection. …

Records Of Bats From Western North Dakota, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

From June 16 to 19 and again from June 24 to 29, 1965, a field party from the Museum of Natural History of The University of Kansas collected mammals along the Little Missouri River at a place 1 mi. S and 1 mi. W Medora, Billings Co., North Dakota. Among the specimens collected were representatives of five kinds of bats, including one species unreported from North Dakota, a subspecies unrecorded from there, and two species known previously from the state by a single specimen each.

Handbook Of Nebraska Trees: A Guide To The Native And Most Important Introduced Species (Revised 1951), Raymond J. Pool

School of Natural Resources: Faculty Publications

Nebraska is not to be classified as a forested state since less than 3 per cent of the area of the state is covered by natural timber. However our native forest trees are numerous as to different kinds and their distribution in the state is characterized by many interesting facts. The every-day life of our people is not so commonly associated with trees as is that of peoples in the more wooded states where lumbering and the wood-working industries are very important occupations because of the proximity of great forests of coniferous or broadleaved trees. The people of Nebraska use …

Epidemiology Of Plasmodium Hexamerium Huff, 1935, In Meadowlarks And Starlings Of The Cheyenne Bottoms, Barton County, Kansas, John J. Janovy Jr.

John J. Janovy, Jr. Publications

A 2-year epidemiological study of Plasmodium hexamerium in meadowlarks and starlings of the Cheyenne Bottoms Waterfowl Management Area, Barton County, Kansas, revealed that seasonal infection incidence varied significantly in the meadowlark, being highest in the early spring and lowest in the winter, but did not vary significantly in the starling. Both host species became infected at an early age, the meadowlark in the nest and the starling soon after leaving it. In concurrent vector studies: (1) Culex tarsalis was infected with P. hexamerium in the laboratory; (2) C. tarsalis, Aedes nigromaculis, and A. sollicitans were exceedingly abundant and fed …

Northward Dispersal Of The Hispid Cotton Rat In Nebraska And Missouri, Hugh H. Genoways, Duane A. Schlitter

University of Nebraska State Museum: Mammalogy Papers

Cockrum (1948 : 306-312 and 1952 : 184-187) summarized the northward movement of the hispid cotton rat, Sigmodon hispidus texianus, in Kansas. He showed that between 1933 and 1947 the cotton rat extended its distribution northward approximately 100 miles-from Greenwood and Allen counties north to Brown County, an average distance of seven miles per year. As of 1952, the northernmost record for the species was 5 mi. S Hiawatha, Brown County (obtained 29 November 1947), in northeastern Kansas. Trapping between 1945 and 1947 in Mitchell, Norton, and Thomas counties, in the central and western parts of northern Kansas, and …

The Shared Vision Of Waldo Frank And Hart Crane, Robert L. Perry

University Studies (University of Nebraska) (1888–1984)

The central purpose of this study is to explore the nature of Waldo Frank's influence upon Hart Crane. More exactly, I will attempt to answer these questions: who was Waldo Frank, what body of ideas did he represent, and which of those ideas were important to Crane? Second, what part did Frank and his ideas play in the composition of Crane's most ambitious poem, The Bridge? These questions are the kind that demand for their satisfaction not only a knowledge of the ideas that each man represents, but also a knowledge of those ideas as they developed in a causal …

Nesting Birds Of The Crescent Lake National Wildlife Refuge, Roger S. Sharpe, Raphael Richard Payne

Nebraska Bird Review

The Crescent Lake National Wildlife Refuge is located in Garden County near the heart of the Nebraska Sandhill Lakes Region. This country is principally rolling mid-grass prairie, the hills reaching a height of as much as 200 feet above the wet meadows. A good portion of the refuge's 46,000 acres consists of these lush meadows which are pocked by marshes, potholes and small lakes. Natural drainage from the surrounding sandhills and springs in the basins feed these water bodies.

The lakes are quite shallow, reaching a depth of perhaps 15 feet. They are alkaline yet are not so highly basic …

Voluntary Intake Of Forage By Holstein Cows As Influenced By Lactation, Gestation, Body Weight, And Frequency Of Feeding, W. L. Johnston, G. W. Trimberger, M. J. Wright, L. Dale Van Vleck, C. R. Henderson

Department of Animal Science: Faculty Publications

Relationships involving forage appetite and frequency of feeding forage were studied with high-producing Holstein cows, including 60 complete cow lactations and 49 records of the dry period. Significant correlation (r= .59) was obtained between forage dry matter intake and 4% FCM yield in the lactation period. Patterns of forage DM intake were affected strongly by different stages of the lactation and dry periods. Infrequent periods of hot summer weather decreased intake and milk yield by about 10%. Individual cow differences, however, were the most important source of variation in forage DM intake. Age, body weight changes, body condition, and stage …

Optimal Farm Organizations For Irrigated Farms In South Central Nebraska, M. D. Skold, A. W. Epp

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This report discusses some adjustment opportunities on irrigated farms in south central Nebraska. Six types of farms are defined depending on the amount of irrigated land and farm size. Profit maximizing farm organizations are computed for nine sets of product prices. The organizations are conditioned by 1961 available resource supplies. Available resources can be reallocated among enterprises to achieve the most profitable organizations.

Studies On The Helminth Fauna Of Alaska. Xliv. Revision Of Ogmogaster Jägerskiöld, 1891, With A Description Of O. Pentalineatus Sp. N. (Trematoda: Notocotylidae), Robert L. Rausch, Francis H. Fay

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Discrepant conclusions in the literature concerning the specific distinction of the two spe- cies assigned to the genus Ogmogaster Jägerskiöld, 1891, necessitated a reevaluation of the taxonomic characters used in separating these trematodes. Study of material from baleen whales from North Pacific waters and from baleen whales and lobodont pinnipeds from the southern hemisphere disclosed the existence of two species which can be distinguished by consistent differences in numbers of ventral ridges, ratio of length of cirrus sac to length of body, and by other morphological characters. Since the original description of O. plicatus (Creplin, 1829) does not permit certain …
