KWRRI Research Reports
This report describes the work done during Part II of a project which had as its aim the development of a way to quantify those intangible values peculiar to a small stream and its watershed. Part I was concerned with an application of the "uniqueness concept" in the evaluation of fifty-eight Kentucky streams. The results of this effort are in Report #40, U. K. Water Resources Institute (1971).
During the second part of the project:
- A method was developed whereby peoples' preferences for natural landscapes could be measured. The method utilized projected color slides and a rating system based on …

KWRRI Research Reports
Samples of water, bottom fauna, and fishes were collected from 66 stations in the Salt River and one of its principal tributaries, the Beech Fork and its tributary, the Chaplin River, Kentucky. Precipitation ranged from 38.86 inches (1969) to 58.04 inches (1970), an increase of nearly 50 percent with marked fluctuations in discharge. Intensive comparisons of phosphates, sulfates, specific conductance, total alkalinity, total hardness, and turbidity showed the streams to be relatively clean and healthy. Nearly 300 different kinds of benthic organisms and other macroinvertebrates have been collected and identified from the basin. Detailed studies of caddisflies and stream drift …

Fao Quelea Research In Africa, Jeffrey J. Jackson
Fao Quelea Research In Africa, Jeffrey J. Jackson
Bird Control Seminars Proceedings
Large scale grain growing schemes are developing rapidly in Africa and the importance of birds as pests becomes more evident each year. Although the potential production of cereals is quite high in some parts of Africa, effective methods for protecting the new schemes from bird damage will have to be developed if their food raising potential is to be realized. The best known of the avian pests of cereals in Africa is Quelea quelea. In addition to their importance as pests their notoriety is due to their intensely gregarious nature. The cloudlike feeding swarms and dense nesting colonies with millions …
Crop Depredations By Waterfowl In Wisconsin, Richard A. Hunt, James G. Bell
Crop Depredations By Waterfowl In Wisconsin, Richard A. Hunt, James G. Bell
Bird Control Seminars Proceedings
On December 5, 1965 the Governor of Wisconsin signed into law a statute permitting claims against the State for damages to crops by wild geese and ducks. This law had been rushed through the legislature in the wake of a rash of crop depredation complaints caused by Canada Geese in their off-refuge feeding flights from the Horicon National Wildlife Refuge. This paper reviews our experiences with waterfowl depredations in the development of a cooperative program by State and Federal wildlife agencies that has held a potentially serious wildlife problem to a minimum of financial losses and public relations concern.
Application Of An Avian Bioenergetics Simulation Model To Red-Winged Blackbird - Crop Relations, John A. Wiens, Melvin I. Dyer
Application Of An Avian Bioenergetics Simulation Model To Red-Winged Blackbird - Crop Relations, John A. Wiens, Melvin I. Dyer
Bird Control Seminars Proceedings
The impact of bird populations upon the properties or processes of ecosystems is mediated through patterns and magnitudes of energy flow. This impact may be either direct, by processing of large quantities of energy or nutrients, or indirect, through feedback control of other ecosystem rate processes or components. In either case, however, the impact is a result of the population dynamics and the pattern and magnitude of food consumption of the birds. Recent research by several groups points to a relatively small direct impact on birds on most natural ecosystems (Wiens 1973). Impact through feedback control, a more difficult relationship …
Tests Of A Potential Method For Decoying Starlings To Bait Stations, Robert E. Williams, Robert G. Schwab
Tests Of A Potential Method For Decoying Starlings To Bait Stations, Robert E. Williams, Robert G. Schwab
Bird Control Seminars Proceedings
The costs of existing Starling control programs prompted the design and test of an alternative method for removing significant numbers of Starlings from heavily damaged areas. The procedure involved the placement of taxidermically prepared adult Starling skins on and near bait stations, accompanied in some cases by broadcasts of recorded Starling vocalizations. Previous studies had indicated that bait stations unaccompanied by live Starling decoys were not acceptable to the birds. Although non-toxic baits were used during these tests to determine the attractability of the stations, ultimate substitution of chemically treated toxic baits was envisioned.
Impact Of Cooling Towers On Bird Migration, Edward J. Rybak, William B. Jackson, Stephen H. Vessey
Impact Of Cooling Towers On Bird Migration, Edward J. Rybak, William B. Jackson, Stephen H. Vessey
Bird Control Seminars Proceedings
Construction of the Davis-Besse Nuclear Power Station on the SE shore of Lake Erie near Port Clinton, Ohio brings a massive, natural draft cooling tower (495 ft. high and 410 ft. wide at base) into migration pathways. Preoperational observations were undertaken to determine whether conditions existed under which the station structures intercepted migrating birds. Preliminary observations were made at the site (Fig. 1) in the fall of 1972 and intensified during the spring and fall migrations of 1973. Construction on the shell of the cooling tower was not completed until late in 1972; thus the full height had not been …

Plant-Animal Interactions: The Effects Of Redwinged Blackbirds On Corn Growth, Melvin I. Dyer
Bird Control Seminars Proceedings
Red-winged Blackbirds (Agelaius phoeniceus) in agricultural crops likely create the worst possible images in the minds of various segments of our society today. To some there is only repulsion, which results in desire for total annihilation of Red-wings (by many agriculturists); while to others there is only attraction, which results in desire to leave the situation absolutely alone (by conservancy minded purists). The great middle ground includes those who vascillate back and forth, between these extremes, those who are not cognizant of the problems, and those that do not care. This picture apparently is a common problem for our wildlife …

Epa Registration And Licensing, Len P. Quattrochi, John R. Beck
Bird Control Seminars Proceedings
Originally we had the old Federal Insecticide, Fungicide, Rodenticide Act (FIFRA) which involved Health, Education and Welfare, Interior, Food and Drug Administration but was administered by USDA. This has been changed by the passage of the Federal Environmental Pesticide Control Act (FEPCA). Now in certain cases you will find that EPA is working through the States under the FEPCA law to develop policy. You will find EPA and the amended FIFRA will play a very important role in your business for several years.
The Effect Of Intense Light On Bird Behavior And Physiology, Sheldon Lustick
The Effect Of Intense Light On Bird Behavior And Physiology, Sheldon Lustick
Bird Control Seminars Proceedings
It has been known for centuries that light (photoperiod) is possibly the major environmental stimuli affecting bird behavior and physiology. The length of the light period stimulates the breeding cycle, migration, fat deposition, and molt in most species of birds. Therefore, it is only natural that one would think of using light as a means of bird control. In fact, light has already been used as a bird control; flood-light traps have been used to trap blackbirds (Meanley 1971); Meanley states that 2000-W search lights have been used to alleviate depredation by ducks in rice fields. Pulsing light is already …

Bird Control Seminars Proceedings
I feel it would be interesting to examine another agricultural statistic to see whether the birds have had any influence on the agriculturists in Ohio with respect to what crops they plant. It is interesting to note that in 1960 we had about 3,383,000 acres of corn grown for grain in the state. That acreage has remained relatively constant. A low point was reached in 1969. The 1969 crop year here in Ohio was an extremely wet season; therefore there was difficulty in getting the crop planted in the spring of the year and difficulty getting the crop harvested in …

It has been suggested that our approach to agricultural bird problems is perhaps wrong, and I feel it would be valuable to ask several individuals to give their ideas as to where their programs are heading right now. I would first like to ask Jerry Besser, the Chief of the Bird Section of the Denver Wildlife Center, to give just a brief statement as to where they are now. BESSER: Most of our efforts are being channelled into the agricul- tural area on a broad scale. Many of the problems are national ones. We can put our finger on the …
Madam Saga - An Approach To An Animal Damage Problem, William D. Fitzwater
Madam Saga - An Approach To An Animal Damage Problem, William D. Fitzwater
Bird Control Seminars Proceedings
While human tinkering with the zoogeographical distribution of lower animals sometimes pays dividends, more often it opens up Pandora's box. Such is the case of the Weaver Finch family. This group of birds is characterized by its colonial habits, granivorous appetite which often counters man's best interests, and elaborate nest structures. The House Sparrow (passer domesticus) is a notable exception of the latter trait as its nests look like a Picasso interpretation of an Afro wig. Weaver Finches originated in Africa. Here they are found in their most numerous forms. The Quelea quelea in flocks of several million compete seriously …
The Monk Parakeet In New York, Douglas P. Kibbe, Noel J. Cutright
The Monk Parakeet In New York, Douglas P. Kibbe, Noel J. Cutright
Bird Control Seminars Proceedings
Attention was focused on the Monk Parakeet (Myiopsitta monachus) in New York State in 1971 when the first successful breeding record was documented for the state although Monk Parakeets had been noticed in New York and New Jersey since 1968 (Bull, 1971). Since 1971 awareness of the bird’s potential for becoming an established species in New York has spread through several segments of the state’s populace. This awareness has been created primarily through two articles in the magazine published by the New York State Department of Environmental Conservation (DEC), The Conservationist (Trimm, 1972) (Trimm, 1973); several articles in popular magazines, …

The Effects Of Fenthion On A Nesting Population Of Quelea During Experimental Control By Aerial Spraying, Jeffrey J. Jackson, Peter O. Park
Bird Control Seminars Proceedings
Quelea quelea is probably the most important avian pest of cereal crops in the sahelian areas of Africa. Its depredations reduce the cereal production of many African nations that lie within its range. To prevent this damage, bird control organizations carry out campaigns to reduce their numbers. Frequently these efforts have given poor crop protection for the cost of control because of inadequate control technology. Factors contributing to the difficulty of carrying out this kind of control are the migrations of the birds which are still incompletely understood, the inaccessability of many nesting areas, the relatively high reproductive potential of …

Fisheries Report No 13 - Results Of A Biological Survey Of The Shire Of Kent, Western Australia, N. L. Mckenzie
Fisheries Research Reports
The Department of Fisheries and Fauna is responsible for the conservation of the native fauna in Western Australia. The main approach to this problem has been the creation of reserves for "The Conservation of Flora and Fauna". These reserves, known as "Wildlife Sanctuaries", are controlled by the Western Australian Wild Life Authority - a Statutory Authority serviced by the Department.
The object of the acquisition programme is to develop a reserve system which will include, as far as possible, a full and permanent cross-section of the State's native floral and faunal assemblages and, at the same time, provide for the …

Enzyme And Tissue Alterations In Fishes: A Measure Of Water Quality, David E. Hinton, M. W. Kendall, J. C. Koenig
KWRRI Research Reports
A variety of freshwater fishes were studied by light and electron microscopy, enzyme histochemical and biochemical methods, The objective was to determine normal structure and function in specific target organs and to compare these to altered states in aquatic pollution. The basic question, "can fish tissues and enzymes serve as indicators of water quality?," was asked. Microscopic alteration in gill was indicative of copper toxicity at an exposure of 20 parts per billion, Gross and light microscopic alterations were indicative of a single exposure of channel catfish to 15 parts per million of methyl mercuric chloride (CH3HgCl). Microscopic …
