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 …

Night Flight Across A Blue Sky: Prognostics, Robert H. Giles Jr.

Bird Control Seminars Proceedings

The purpose of this presentation is to gain new perspectives on pest control and related phenomena. Some will call it “blue sky.” I would claim it informal futuristics. Systems men call such efforts feedforward; others grandify it with “prognostics.” Some say prognostics is one of the leading challenges of the day. We must anticipate future developments and imagine or invent new alternatives as a background for rational choice. The activity can influence today’s decisions, modify our concepts of risks and probable payoffs, and can help those of us who ask: “What am I really doing; what should I be doing?”

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 …

Avitrol 1973, Richard O. Winters

Bird Control Seminars Proceedings

The Federal Registration for Avitrol to be used in standing field corn restricts use to application under supervision of Governmental agencies trained in bird control. The majority of current Avitrol labels state, "For use by or under supervision of government agencies or pest control operators. Not for sale to the public." This slight difference has already caused much discussion and the matter isn't resolved yet. There are different interpretations of this statement. Also for crops the material is only registered for field corn. There is a need for the material to be registered for sweet corn and sunflowers, although I …

The Monk Parakeet And New Jersey Agriculture, Charles A. Wagg

Bird Control Seminars Proceedings

Parrots and parakeets have been brought into the United States for as long as our sailors have sailed to the distant tropics. In more recent years, the keeping of exotic pets increased to almost fad proportions. The pet shops and importers have kept the United States supplied with a vast array of these species. Among them is the Monk Parakeet. Large numbers of Monk Parakeets have been imported to satisfy the demand for parrot-like birds. The largest percentage of these birds went to pet stores and ultimately ended up in homes as pets. Unfortunately, some of these birds were released …

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.

Pricing, John R. Beck

Bird Control Seminars Proceedings

I would like to make six points concerning pricing. Number one, there is a great deal of time required in observation. Secondly, there is no such thing as a cheap bird job. Third point: there is no job that is routine. The fourth point: observations are necessary to delineate the species, the type of environment, human interference, the type of job it is going to be, and the needs of that job. The fifth point: bird work cannot be assigned to a person who does not appreciate the need for technical compliance with laws and regulations. Number six: do not …

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 …

A Bibliography On The Red-Winged Blackbird, Noel J. Cutright

Bird Control Seminars Proceedings

Following the completion of my doctoral dissertation on the Red-winged Blackbird, I decided to compile a bibliography on the species. This bibliography updates and expands the selected bibliography on Redwings prepared by Mealey and Mitchell in 1966. No effort was made to list the many progress and final reports on various aspects of blackbird research issued by the Bureau of Sport Fisheries and Wildlife. Literature citations follow the Style used in The Journal of Wildlife Management.

Bird Management On The Farm And At The Processing Plant, Thomas K. Palmer

Bird Control Seminars Proceedings

Bird management, whether conducted on farms or at food processing plants, utilizes a rather limited number of techniques in conjunction with an intimate knowledge of pest avian behavior. The deployment of bird management techniques is dependent upon the complexity of pest induced environment and limitations imposed by human, moral, political, social and economic pressures.

Pest Bird Control In And Around Food Processing Plants, Jerry W. Keown

Bird Control Seminars Proceedings

When a food product arrives at a food processing plant or a food warehouse, an additional element of concern is introduced. Under the Federal Food Drug Cosmetic Act, Chapter IV, "Food", Section 402, describes "Adulterated Food" as under A3, if it consists in whole or in part of any filthy, putrid, or decomposed substance, etc. A4, if it has been prepared, packed or held under unsanitary conditions whereby it may have become contaminated with filth, etc. Pest birds living in or on the exterior of a food plant are there- fore just as great a concern to food plant operators …

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 …

A Field Test Of Methiocarb Efficacy In Reducing Bird Damage To Michigan Blueberries, Richard A. Dolbeer, Charles R. Ingram, Allen R. Stickley Jr.

Bird Control Seminars Proceedings

Over 20,000 acres of highbush (cultivated) blueberries are grown in the United States (Johnston et al. 1969). The major producing states are Michigan, New Jersey, North Carolina, Washington, Indiana, and Oregon. Bird damage to blueberries is widespread and sometimes severe (Vaile and Moore, 1968; Pearson, 1958; Hayne and Cardinell, 1949; and Schwartze and Alcorn, 1960). Unfortunately, accurate estimates of less from birds are lacking. Non-lethal methods of controlling bird damage are essential since much of the damage is caused by popular song birds protected by Federal law. Scare devices, including exploders and electronic broadcast alarms, are often used with variable …

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 …

Where Are We? - National Scene, Richard N. Smith

Bird Control Seminars Proceedings

When the question is asked, “Where are we?”, we must compare our progress to where we were in the past or to a goal of the future. When we do this, it is apparent that much has been accomplished during the past ten years, however, the goal of alleviating bird damage to all agricultural crops has not yet been met. We have developed methods to combat crop losses (Avitrol, scaring devices), we know more about bird population dynamics, more about bird behavior and physiology. Yet, there is much more to accomplish, for we have a number of bird crop damage …

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 …

Morphological And Ecological Relationships Of Etheostoma Caeruleum And Etheostoma Spectabile In West Central Indiana, Dennis E. Clark

All-Inclusive List of Electronic Theses and Dissertations

Etheostoma caeruleum Storer and Jii. spectabile (Agassiz) are closely related members of the family Percidae, subfamily Percinae, tribe Etheostomatinae. This group, consisting mostly of small, brilliantly colored darters, has been partially characterized by Collett ( 1963). Several papers have been published dealing with the biology of these two species. One or both species have been described by Storer (1845), Agassiz (1854), Reeves (1907, but see Trautman, 1930), Trautman (1930, 1957) Knapp (unpublished Ph.D. dissertation), Distler (1968), and others. Trautman (1930, 1957) Gerking (1945), and Hubbs and Lagler (1947) reported that h caeruleum lives in larger and faster streams, whereas JL_ …

The Foods And Feeding Habits Of Botulism Intoxicated And Healthy Waterbirds On The Bear River Refuge, Utah With Emphasis On The American Avocet And Blacknecked Stilt, George W. Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Primary objectives of this study were: (1) to compare the food habits of healthy and botulism intoxicated American avocets and blacknecked stilts for qualitative and quantitative differences, (2) to determine which invertebrates found in the tracts of intoxicated and healthy birds contained type C toxin, and (3) to explain apparent susceptibilities among different sexes, ages and species of birds.

Based on percent utilization and occurrence of food items in the esophagus, the diets of healthy and intoxicated birds were similar. However, intoxicated avocets consumed higher proportions of Gastropoda and intoxicated stilts more Hydrophilidae larvae than did healthy birds. Because of …

Reproduction In The Red Squirrel (Tamiasciurus Hudsonicus) In Colorado, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Information on reproduction of the red squirrel (Tamiasciumrs hudsonicus) can be gleaned from studies in the northeastern United States (Klugh, 1927; Hamilton, 1939; Layne, 1954) and in western Canada (Miller, 1970; Smith, 1968; Kemp and Keith, 1971; Wood, 1967). However, there is a paucity of information on reproduction from the mountainous regions of the western United States. This paper presents reproductive information on the red squirrel from Colorado and helps fill this void. In addition, the reproductive strategy of red squirrels is briefly compared with that of snowshoe hares.
