A Bibliography On The Red-Winged Blackbird, Noel J. Cutright
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.
Legal Requirements And Status Of Protected Bird Species, Richard N. Smith
Legal Requirements And Status Of Protected Bird Species, Richard N. Smith
Bird Control Seminars Proceedings
Migratory birds found in North America are protected by the Migratory Bird Treaty Act, which implements migratory bird conventions between the United States and Great Britain and the United States and Mexico. An amendment to the Act in 1972 placed all migratory bird species except for exotic species such as Starlings, Pigeons, and House Sparrows in a protected status. There are sections within the Act that allow for the issuance of permits to take protected species. Those sections that are of the most concern to the pest control operator deal with certain blackbird species that cause agri- cultural crop damage …
Insurance, Mark Weisburger
Insurance, Mark Weisburger
Bird Control Seminars Proceedings
We have been working with exterminators on the insurance problems for thirty-five or so years. Recently PCO’s have been doing much in the way of bird control. There does not seem to be anyone that we know of who does strictly bird control insurance, so our group always ties it in with our pest control. I feel that nothing touches everyone so regularly, with the exception of the federal government, as your insurance premiums. I would like to discuss with you the causes and results of accidents and how they can effect insurance premiums.
Bird Control In Milwaukee : A Case History, Laverne A. Penn
Bird Control In Milwaukee : A Case History, Laverne A. Penn
Bird Control Seminars Proceedings
In planning a city-wide pigeon control program, many problems must be considered to conduct such a program safely and efficiently. The City of Milwaukee Health Department has been engaged in some degree of nuisance bird control activity for more than thirty years. Early attempts at bird control consisted of using fireworks, rubber snakes, paper mache owls, and other devices to prevent starling roosting. All met with very limited success and were eventually abandoned. Until the post World War II period, Milwaukee, like most large cities, was plagued by an abundance of homeless pigeons. Pigeons were abundant on downtown streets, commercial …
Pricing, John R. Beck
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 …
Cowbird Trapping And The Kirtland’S Warbler, Richard O. Winters
Cowbird Trapping And The Kirtland’S Warbler, Richard O. Winters
Bird Control Seminars Proceedings
The 1971 census of the Kirtland’s Warbler taken on the warblers nesting grounds in North Central Michigan revealed that the population of this species had dropped to an all-time low of 201 singing males, as compared to 502 in 1961, a drop of some 60 percent in ten years. Breeding birds, furthermore, once found nesting in as many as nine counties during one nesting season returned to nest in only five counties in 1972, at which time the census indicated that the warbler population was remaining temporarily stable at approximately 200 singing males. Since the sex ratio of this species …

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

A Program For Developing Male Chemosterilants For Red-Winged Blackbirds, Joseph L. Guarino, Edward W. Schafer Jr.
Bird Control Seminars Proceedings
Red-winged Blackbirds (Agelaius phoeniceus) are one of the primary species of birds contributing to agricultural damage throughout the United States. Methods have been developed for reducing the damage they cause to ripening corn (De Grazio et al. 1971; 1972), sprouting corn (Stickley and Guarino, 1972), ripening rice (DeHaven et al. 1971), and windrowed peanuts (Mott et al. 1972). These methods frighten or repel Redwings from crops; however, in some situations, techniques are also needed to manage specific problem-bird populations by reducing their numbers. At present, the primary methods for reducing large numbers of problem birds involve the use of chemical …
Population Estimates, Thomas Stockdale
Population Estimates, Thomas Stockdale
Bird Control Seminars Proceedings
In dealing with population estimates, we need to determine first the reason for estimating the population. If we are dealing with a local situation, are we concerned with a local estimate? If we are dealing with a regional problem, are we concerned with a regional estimate? The blackbird problem is chiefly a regional problem, but we need to look at broader horizons than just local or regional situations. Are we dealing with a national problem? Is this problem a year-round one or is it a seasonal problem? We may want to know just purely the number of birds we are …

Winter Populations, Robert A. Pierce
Bird Control Seminars Proceedings
I imagine we in Arkansas have more bird roosts than any other state in the nation. I think we could find 50 bird roosts this winter that have a million or more birds in each of them. Our problem is that we have these birds sitting in the wrong place; and we, along with the Wildlife Services people, have worked pretty hard on developing a technique for moving birds from where there are a lot of people to where there are very few people.
Aerially Applied Methiocarb Spray For Protecting Wild Lowbush Blueberries From Birds, Rene M. Bollengier, Joseph L. Guarino, Charles P. Stone
Aerially Applied Methiocarb Spray For Protecting Wild Lowbush Blueberries From Birds, Rene M. Bollengier, Joseph L. Guarino, Charles P. Stone
Bird Control Seminars Proceedings
Ripening blueberries are subject to serious damage by a variety of bird species. Through a questionnaire survey, Pearson (1958) calculated that losses of highbush blueberries to birds in Massachusetts averaged about $38,000 a year in 1955-57. From a 1972 questionnaire on bird damage to highbush blueberries directed to individuals in 14 states, Mott and Stone (1973) estimated that birds damaged at least 5% of the crop, representing a minimum nationwide loss of about $1.6 million. Most species of birds that feed on blueberries are not only desirable but also protected under the Migratory Bird Treaties Act. Any means of reducing …
Damage Surveys In Ohio And Michigan, Richard O. Winters
Damage Surveys In Ohio And Michigan, Richard O. Winters
Bird Control Seminars Proceedings
Blackbirds, Red-winged Blackbirds in particular, have caused millions of dollars worth of damage to corn crops in Ohio and Michigan and throughout the country. Concentrated efforts to estimate and document the damage in Ohio and Michigan were initiated in the fall of 1966. Besides yielding an annual estimate of blackbird damage, it was hoped that the survey would eventually be held to establish the effectiveness of control efforts, particularly the use of Avitrol. However, the large variability inherent in the damage sampling procedure has precluded documentation of changes in the amount of damage due to control efforts. In order to …
Hopper Box Treatment Of Corn Seed With Methiocarb For Protecting Sprouts From Birds, Charles R. Ingram, Robert T. Mitchell, Allen R. Stickley Jr.
Hopper Box Treatment Of Corn Seed With Methiocarb For Protecting Sprouts From Birds, Charles R. Ingram, Robert T. Mitchell, Allen R. Stickley Jr.
Bird Control Seminars Proceedings
Methiocarb [3,5-dimethyl-4-(methylthio)phenol methylcarbamate = R Mesurol1] showed promise as a bird repellent for protecting crops in 1964, when field tests in South Dakota indicated reduced pheasant damage to sprouting corn (West et al., 1969). Stickley and Guarino (1972) then showed marked reduction of blackbird damage to sprouting corn in South Carolina when methiocarb in a water slurry formulation was used as a seed treatment at the 0.5-percent level by weight of seed. Our test, in 1973, was conducted to determine the repellent efficacy of methiocarb on sprouting field corn when the powdered chemical is placed directly in the planter hopper …
Bird Damage To Agricultural Crops In The United States -- A Current Summary, Charles P. Stone
Bird Damage To Agricultural Crops In The United States -- A Current Summary, Charles P. Stone
Bird Control Seminars Proceedings
Determination of the importance and distribution of bird damage to agricultural crops in the United States has been emphasized by the Section of Birds at the Denver Wildlife Research Center in recent years. Our studies can be placed in two general categories: (1) For some crops we have conducted statistically designed quantitative field surveys to determine bird damage and have extrapolated from test plot data, and (2) for other crops we have directed questionnaires to persons knowledgeable about bird damage. Questionnaire surveys are obviously subjective and are biased to an unknown degree, but for some crops there is no reasonable …
Avitrol 1973, Richard O. Winters
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 …

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.
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 …
Investigation Of Bird Migration And Mortality At The Omega Navigation Station, Lamoure, North Dakota: Fall 1972 And Spring 1973, Michael L. Avery, Paul F. Springer
Investigation Of Bird Migration And Mortality At The Omega Navigation Station, Lamoure, North Dakota: Fall 1972 And Spring 1973, Michael L. Avery, Paul F. Springer
Bird Control Seminars Proceedings
An investigation of bird migration and mortality at the U.S. Coast Gaurd’s Omega Navigation Station, located in the flood plain of the James River near LaMoure, North Dakota, began in September 1971 following the completion there of the 1,200-foot transmitting tower. The objectives of the study are: 1. To determine the nature of bird migration through the tower area and adjacent regions. 2. To determine the magnitude of bird losses caused by the tower. 3. To determine the influence of weather patterns on bird migration and losses. 4. To develop and evaluate methods for reducing bird losses at towers. This …
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 …
Use Of Plastic Netting, John T. Stucky
Use Of Plastic Netting, John T. Stucky
Bird Control Seminars Proceedings
Conwed Plastic Division was approached two years ago regarding the use of plastic netting as a means of keeping birds from feeding in vineyards and other fruit crops. As a result of working with various interested people on the west coast, we developed a black pigmented, ultraviolet light (sunlight) stabilized netting. This netting maximizes the resistance against sunlight exposure and has very good tensile strength. The following demonstrates what individual farmers have achieved using Conwed Plastic Bird Control Netting.

Use Of Perches At Refinery Sites, J. J. Dill
Bird Control Seminars Proceedings
I was listed to speak about bird control on industrial sites, so I have selected three or four of the more interesting jobs that we have worked on over the past ten years. Naturally the ones that the pest control firms call us about are those that they have tackled from several different angles and been unable to solve. As a result of this, we have had several really interesting bird control jobs in conjunction with pest control firms. I think each one of them will point out different problems and ways to solve them. The first of the jobs …
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 …

The subject I have been asked to speak on is “Where Are We?” As I assess it, I think that we, those who are using bird management agents and methods, Federal, State, and other agencies representing research, extension and regulatory, and manufacturers of agents used in bird management, are standing in the middle of a busy intersection and the light has just turned yellow. Some of us have tape across our mouths and cotton stuck in our ears. I think that we have arrived at this intersection in a number of different ways. Some of us have taken separate paths, …
Where Are We In Bird Control The Urban Scene, C. W. Marshall
Where Are We In Bird Control The Urban Scene, C. W. Marshall
Bird Control Seminars Proceedings
Four (4) major bird control methods are presently registered: (1) Bird repellents (2) Stomach distress repellents (3) Contact poisons (4) Stomach poisons Seven hundred and sixty seven (767) companies out of 1800 NPCA members indicate they are engaged in bird control. This number will undoubtedly grow for birds do constitute a health, economic and nuisance problem. The amended FIFRA Act will undoubtedly have an effect on bird control methods. More restrictions will probably be placed on such poisonous materials as endrin and strychnine. If endrin is allowable, “perch” use will be the only methods, strychnine will probably be greatly restricted. …
A Field Test Of Methiocarb Efficacy In Reducing Bird Damage To Michigan Blueberries, Richard A. Dolbeer, Charles R. Ingram, Allen R. Stickley Jr.
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 …
