The object is to hash over a few problems as we see them on this red-winged blackbird situation. I'm Mel Dyer, University of Guelph, Guelph, Ontario. Around the table are Tom Stockdale, Extension Wildlife Specialist, Ohio Cooperative Extension Service, Columbus; Maurice Giltz, Ohio Agriculture Research and Development Center, Wooster, Ohio; Joe Halusky, U.S. Fish and Wildlife Service, Columbus, Ohio; Daniel Stiles, U.S. Fish and Wildlife Service, Washington, D.C.; Paul Rodeheffer, U.S. Fish and Wildlife Service, Columbus, Ohio; Brian Hall, Blackbird Research Project, University of Guelph, Guelph, Ontario; George Cornwell, Virginia Polytechnic Insti¬tute, Blacksburg, Va.; Dick Warren, Peavey Grain Company, Minneapolis, …

Bird Control Methods And Devices--Comments Of The National Pest Control Association, Philip J. Spear

Bird Control Seminars Proceedings

It may be useful to review some of the considerations that go into recommendations concerning bird management. Later I will make some comments concerning specific methods and devices being used in or promoted for bird control work regardless of whether or not they are new. Members of the National Pest Control Association provide a variety of services, such as fumigation, termite control and general pest control which includes rodent control. There are eight such categories listed in our roster, but only one member in five provides every service listed. Bird control is a rather recent development and is the newest …

Blackbird Depredations In Animal Industry: Feedlots, Donald Balser

Bird Control Seminars Proceedings

Reviewing the cattle feedlot problems in the west, we have cattle feedlots near most of our large population centers and in some cases they are located near supplies of rations, such as potatoes in Idaho or beet pulp, milo, etc. Perhaps the greatest number of feedlots are in California which has our largest human population but there are also large operations in Utah, Idaho, Oregon, Colorado, Nevada, New Mexico, and Arizona which have reported bird damage problems. Later on in the program we'll have a film taken by our bird project personnel of work in feedlots in Colorado so I'll …

Blackbird Depredations In Animal Industry: Poultry Ranges And Hog Lots, C. E. Faulkner

Bird Control Seminars Proceedings

I'm going to move over onto poultry ranges, turkey ranges and hog farms where we have species of birds such as the herring gull, the pigeon, the starling and English sparrow. As a rule, these birds travel relatively great distances from roosts and loafing areas out to the feeding ranges. And why shouldn't they? There is ample high energy food available and usually lack of human disturbance. So they frequent these places during the daylight hours. Actually the losses from these operations are pretty hard to evaluate. Sometimes it is direct, the farmer feels the impact; other times it's indirect. …

Bird Damage In Fruit Crops, Richard N. Smith

Bird Control Seminars Proceedings

I don't see any solution in sight for fruit damage caused by birds. I think that one of the reasons is that there has been very little research done concerning the relationship between birds and fruit crops. Probably the reason is that those birds responsible are protected species, and they are highly desirable birds in the eyes of the public. For instance, one of the species that is responsible for heavy losses in fruit crops is the robin. It is the state bird in Michigan, yet it causes a number of problems there each year. Another problem is that growing …

New Materials From Research, Donald Balser

Bird Control Seminars Proceedings

At the Denver Wildlife Research Center our people are actively searching for means of controlling damage by a whole host of animal and bird species. I say controlling damage rather than controlling species because this should be the primary objective. If we can do this without lethal control, so much the better, and it may be the more lasting solution in the long run. Often removal of some animals by lethal means either increases reproduction, survival, or invasion unless complete control is exercised over sufficiently large areas. In spite of these problems, population reduction is often relied on as a …

Histoplasmosis--Its Relationship To Birds, E. R. Price Ph.D.

Bird Control Seminars Proceedings

Histoplasmosis is a disease affecting man and many other ani¬mals including the dog, cat, cow, horse, and several wild animals. It is caused by a pathogenic fungus known as Histoplasma capsulatum. This fungus lives and multiplies in the ground as a mold. It prefers the undisturbed litter in and around old chicken houses or in undis¬turbed droppings under bird roosts. It has been found in the soil of dog kennels, under porches of old houses, under trees and bushes frequented by birds in the daytime. It has also been found in isolated caves and hollow trees. It apparently is capable …

Metropolitan And Industrial Bird Problems: Panel Discussion, Harold Coleman, Anthony Clay, Kilmer Bortz

Bird Control Seminars Proceedings

As a pest control industry, we are interested in bird control, especially in areas of residence, commercial buildings, food plants, mills and elevators, commercial feed lots, farms, and even area wide controls in some of our cities. We run into all kinds of problems; I suppose you men do, too.

Good Practice In Bird Management, James W. Steckel

Bird Control Seminars Proceedings

I'm going to deviate a little bit from what's been said. I'd like to read to you first of all a Good Practice Statement for Bird Management that was accepted by the National Pest Control Association in the past year, 1965. I think it's important for all the people here, realizing that some of you are suppliers, some of you are from regulatory agencies, some of you are in the bird management business, and others are in¬terested in this field in many other ways. It's important for us to realize, all of us, that this field is just in the …

Control Of Birds In Aircraft Hangars, Richard N. Smith

Bird Control Seminars Proceedings

What I am going to say this afternoon about bird control in hang¬ars won't take but a few minutes, mainly because I think this is one area that we already have partial solutions. By this I mean that in most instances, at least where I've worked, we've been able to solve most of the hangar bird problems. Some of you have probably worked on similar problems or have worked in airplane hangars and after the session I'll certainly welcome any comments you may have. What I have to say will relate mainly to what I've done myself, or the men …

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 …

Mineralized Springs In Utah And Their Effect On Manageable Water Supplies, James H. Milligan, Ray E. Marsell, Jay M. Bagley

Reports

Need and Importance of Study

Water demands in Utah are continuously increasing. It is essential that these demands be me to insure the continued enhancement of the social and economic well-being of all sectors of our society. Since water needs must be met from a relatively fixed water supply it is imperative that supplies be managed for complete utilization in such a way that all legitimate requirement scan be satisfied.

As our available water supplies are used more completely by making a given supply satisfy more than one use, water quality problems become more pronounced. The multiplicity of uses to …

Development, Verification, And Use Of Methods To Model Chemical And Thermal Processes Lakes Mead And Powell, Bureau Of Reclamation

Publications (WR)

PURPOSE The purpose of the proposed research is to quantify the effects that Lakes Mead and Powell have on the salinity in the Colorado River system, and to evaluate changes that cap be made to the operating system of the reservoirs (within legal/institutional constraints) to enhance salt precipitation and/or minimize evaporation within the reservoirs. The effect of any changes (i.e., selective withdrawal uses, pumped storage, etc.) on reservoir evaporation could also be evaluated with a goal of minimizing evaporation. This will be accomplished through the development of a mathematical model of the reservoirs as described below. BACKGROUND Two major problems …

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 …

Man And His Water Resource, Dean F. Peterson

Faculty Honor Lectures

Several preceding honor lectures have dealt with water. The title of a recent one, "Water and Man," by Dr. Sterling Taylor closely resembles the one for this paper. Dr. Taylor's paper dealt primarily with the physical science of water. This one will consider the nature of the use of water by man and the technological and institutional structure related to that use. Thus there should be no serious overlap. My friends in the social sciences may be surprised, too, to find that somehow this lecture has spilled over into their territory. But engineering is the implementation of science and technology. …

United States Army Corps of Engineers, Omaha District

This report on Antelope Creek, Dead Mans Run, and Middle Creek is the second in a series of flood plain information reports being prepared for streams in the Lincoln, Nebraska metropolitan area. Volume I of this series, published in August 1964, described flood hazard areas of Salt Creek Haines Branch, and Beal Slough.

This Technical Appendix, covering Antelope Creek, Dead Mans Run, and Middle Creek, is presented in four sections. Section A presents information applicable to all three streams. Sections B, C, and D are devoted to information applicable to the individual streams.

Antelope Creek, Dead Mans Run And Middle Creek: Salt Creek Basin, Volume Ii: Summary Report, United States Army Corps Of Engineers, Omaha District

United States Army Corps of Engineers, Omaha District

Antelope Creek and Dead Mans Run, right bank tributaries of Salt Creek, rise within the Lincoln metropolitan area near the town of Cheney, and 84th and A Streets, respectively. These streams flow in a northwesterly direction and drain 14 and 10.5 square miles, respectively. Middle Creek, a left bank tributary of Salt Creek, rises in eastern Seward County and drains 100 square miles as it flows in an easterly direction to join Salt Creek in Lincoln. Urban development in these valleys is concentrated within the Lincoln city limits. Elsewhere the valleys are rural in character, with the land devoted to …

Stage-Fall-Discharge Relations For Flood Flows Over Highway Embankments, Gaylord V. Skogerboe, M. Leon Hyatt, Lloyd H. Austin

Reports

At Utah State University, considerable effort has been devoted to the analysis of submerged flow at open channel constrictions. A method of analyzing submerged flow was first developed for a trapezoidal flume by Hyatt (1965). Later studies verified the method of analysis for a rectangular flume (Skogerboe, Walker, and Robinson, 1965) and Parshall flumes (Skogerboe, Hyatt, England, and Johnson, 1965). Because of the previous findings, it was felt this method of analyzing submerged flow could be applied to highway embankments.

A highway embankment is a form of broad-crested weir when overtopped by flood waters. Being a weir, the flood discharge …

Modifications To Gate-Flume Structures On The Weber Davis Canal, Gaylord V. Skogerboe, M. Leon Hyatt

Reports

The turnout structures under study divert flows from the Weber-Davis Canal near Clearfield, Utah. A portion of the canal in this area was realigned as a result of the construction of the Interstate Highway System. The twin turnout structures, used to divert water to the West Branch Irrigation Company and West Layton Irrigation Company, were constructed in conjunction with the realignment of the concrete -lined canal.

A three-dimensional drawing of the twin turnout structures is shown in Fig. 1. Water is diverted from the canal by passing under the discharge diverted through each of the structures is approximately 35 cfs …

Fisheries Report No 3 - Western Australian Freshwater Fisheries, Donald D. Francois

Fisheries Research Reports

Most of the Australian States have a comprehensive system of inland waterways, Western Australia, however, is in a less fortunate position. True, the maps of the State show many rivers, but in much of the southern, more populous part, with no summer rain and no winter snow, the majority are virtually a chain of waterholes during the long summer months. At the same time, in a relatively small section in the south-west corner, there is a series of permanent streams flowing through what was originally dense forest. But apart from the three indigenous freshwater crustaceans, the marron (Cherax tenuimanus), the …

Population Distribution And Mobility Of Deer In Eastern South Dakota, Rollin De Mers Sparrowe

Electronic Theses and Dissertations

Population distribution and mobility of deer were studied intensively along a 15-mile stretch of the Big Sioux River, and less intensively on an expanse of 1400 square miles in central eastern South Dakota. Objectives were to determine relative population numbers and distribution of deer, the extent of their daily and seasonal movements, and the principal factors influencing these populations and movements, and to test winter hard counts as a population index. Deer were captured in Clover traps or with a Cap-Chur gun and were marked individually with ear tags, ear streamers, and collars. Some deer were tracked by radio telemetry. …

Economic Analysis Of Alternative Flood Control Measures By Digital Computer, Thomas M. Rachford

KWRRI Research Reports

The purpose of this project was to develop a digital computer program for selecting the optimum combination of flood proofing, flood-plain land use, channel improvement, and residual flood damage for a given floodplain. Based on economic efficiency, the optimum policy is selected for each planning unit of the total flood-plain for each period of time called a planning stage. The program was written in Fortran IV for the IBM 7040 and the University of Kentucky Computing Center compiler. The program requires about 23,000 words of core storage and about 30 seconds of execution time per planning-unit-stage for typical conditions. The …

Limnology Of Three Farm Ponds In South-Central South Dakota, Larry Kim Graham

Electronic Theses and Dissertations

Physical, chemical, and biological aspects of three farm ponds in south-central South Dakota were studied from June 1964 until December 1965. Maximum water temperature at the surface reached 25.2 C, while water temperatures at the bottom of the ponds were about 2 to 4C lower than the surface. Light transmission was influenced by turbidity but generally penetrated to the bottom of the ponds except during periods of cloudy ice and snow cover. Dissolved oxygen was near saturation during periods of open water. Most chemical ions in the ponds increased annually from a winter minimum to a spring maximum. Total dissolved …

Proceedings Of A Summer Institute In Water Resources: Volume 4 - General Principles Of Water Resources Planning, Aaron Wiener, P. Zusman, W. R.D. Sewell, Harvey O. Banks

Reports

Foreward: Recognizing the need for training of individuals to meet the rapidly rising problems connected with water resources development, Utah State University, with National Science Foundation support, organized a Summer Institute in Water Resources for college teachers. it was hoped that participants carefully selected from all regions of the country would receive additional insight and stimulation to improve and enlarge water resources training programs at their own institutions. Thus, the accelerated dissemination of such knowledge on a national scale could be facilitated. Realizing further that the key to a successful institute of this nature lay in the excellence of its …

Measuring Water With Parshall Flumes, Gaylord V. Skogerboe, M. Leon Hyatt, Joe D. England, J. Raymond Johnson

Reports

Preface: As the value of water increases, the extent to which measurement is employed in an irrigation system also increases. Additional flow measurements provide information for improved management of the water supply. Good water management requires accurate measurement. Many devices have been developed for this purpose and are in use. Included among them are weirs, orifices, calibrated gates, Parshall flumes, and current meters. Of these, the Parshall flume is one of the most widely accepted and used. Presented in this publication is a discussion concerning the use of Parshall flumes for measuring water, including the utilization of a new approach …
