Studies On The Movements Of Blackbirds And Starlings In The West End Of Lake Erie, Maurice L. Giltz, Harold E. Burtt

Bird Control Seminars Proceedings

The operation of decoy traps at The North Central Farm, Vickery, Ohio, the Ottawa-Crane Creek-McGee Marsh Area, and on the Bass Islands in Lake Erie, has permitted the banding of thousands of Red-winged Blackbirds (Agelaius phoeniceus), Common Grackles (Quiscalus quiscala), Brown-headed Cowbirds (Molothrus ater), and Starlings (Sturnus vulgaris). The repeats and returns of these banded birds justify inferences concerning the sex and age ratios in the populations and the stability of the populations, as well as indicating the seasonal migrations and movements of the populations.

Serum Calcium Levels Of The Red-Winged Blackbird (Agelaius Phoeniceus), Tim Burkholder

Bird Control Seminars Proceedings

Serum calcium levels were analyzed by atomic absorption spectrophotometry during different stages of development of the Red-winged Blackbird (Agelaius phoeniceus). The effects of the reproductive cycle, growth, and soil calcium on mean serum calcium levels in this species were analyzed as were the effects of mean serum calcium levels on eggshell thickness, hatchability, and egg production.

Nonbiolog1cal Alteration Of 3-Chloro P-Toluidine Hydrochloride (Drc-1339) In An Aqueous Solution, T. R. Darden, Robert G. Schwab

Bird Control Seminars Proceedings

The effectiveness of 3-chloro p-toluidine (DRC-1339) as an avicide, particular¬ly on the European starling, has been adequately demonstrated (DeCino, Cunningham, and Schafer, 1966; Schwab, 1965, 1966, and 1967). Methods of applying the com¬pound which have proved useful range from the standard baiting technique (Besser, Royall, and DeGrazio, 1967; Royall, DeCino, and Besser, 1967; West, 1968) to pos¬sible aerial application of the compound to roosting sites (Schwab, 1967). These methods, particularly the latter, inherently lead to widespread environmental exposure. As the chemical name implies, DRC-1339 is a chlorinated hydrocarbon. It thereby carries the stigma, whether justifiable or not, of environmental persistence …

Food Choice Behaviour, R. G. B. Brown

Bird Control Seminars Proceedings

Since 1965 the Canadian Wildlife Service has been concerned with the damage which birds cause in the orchards and vineyards of the Niagara fruit belt, in southern Ontario. My own contribution to this programme has been to collect information on the feeding be¬haviour and ecology of the birds concerned, and use this to test the effectiveness of various control systems. For the purposes of this seminar, I shall only deal with the damage which Robins do to sweet cherries. Here, I was particularly interested in whether it was possible to develop a "bird-proof cherry variety, which would settle the problem …

Industry Consideration And Approach, John R. Beck

Bird Control Seminars Proceedings

Many people are quite concerned and interested in the development of new avicides and in the continuation of existing ones. I think there are certain directions that the public at large expects industry and government to go in regards to control operations, pollution, and so forth. One of the things I think we need to concern our¬selves with is the fact that several biologically-oriented control mechanisms in control programs have been overlooked, sometimes intentionally. In the future, reg¬istration and regulatory groups are going to show more interest and a more amenable attitude toward biologically-oriented control programs, mechanism, and materials. Certainly …

Another Perspective On Bird Management, John M. Anderson

Bird Control Seminars Proceedings

At an earlier research seminar, Dr. John Seubert observed that available evi¬dence indicated the red-winged blackbird was going to be with us for some time, and perhaps we'd better learn to "live with it." Whereupon a representative of the com growers said if Dr. Seubert really believed that, he'd better look for a new job. I sincerely hope this attitude is not too widespread among corn producers and market¬ers; because if it is, we can expect a lot of pressure designed to force scientists to abandon their search for a safe method of reducing redwing damage. "Risk now, find out …

Bird Management At Airports, Edward R. Ladd

Bird Control Seminars Proceedings

In New England, and along the stretch of coastline which starts just south of Canada and goes down through New Jersey, we have half a dozen major or what we call international airports. All but two have bird problems. Most of these airports were built on submarginal land, but what was perhaps some of the best wildlife habitat in the country. So, the birds were there first. When these airports were built, airlines were flying propeller-type aircraft. This type was slow and sluggish compared to the jet aircraft of today. Even though aircraft speeds have increased, the birds still are …

Bird Hazards To Aircraft, Victor E. F. Solmon

Bird Control Seminars Proceedings

When I spoke to the third Bird Control Seminar in 1966 on "Ecological Control of Bird Hazards to Aircraft", I reviewed what we had accomplished up to that time. I spoke about the extent of the problem, the bird species involved and the methods we used to make the airports less attractive to birds that created hazards to aircraft.

I wish to discuss today our accomplishments since 1966. I have presented a number of papers on the topic including one with Dr. W. W. H. Gunn, in 1967 at a meeting in the United Kingdom, and others in the United …

Taxonomy Of The Neotoma Albigula-Group Of Woodrats In Central Mexico, E. Raymond Hall, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Study of specimens collected from critical localities since 1944 reveals that: Neotoma montezumae and N. leucodon zacatecae are indistinguishable from earlier named taxa; N. latifrons is a subspecies of an earlier named taxon; and N. palatina, previously known from only one specimen and thought by some mammalogists to be merely an aberrant individual of Neotoma albigula, is a species distinct from N. albigula as Goldman tentatively decided when he named it 64 years ago. In the narial passage, the partition formed by the vomer that extends well behind the hard palate as a sword-like projection is present in …

A Syncoeliid (Hemiuroidea Faust, 1929) Metacercaria On A Copepod From The Atlantic Equatorial Current, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The complete life cycle for a species of Syncoeliidae Odhner, 1927, is unknown. Adults are known from the branchial cavity and mouth of marine fishes which are usually found offshore, and second intermediate hosts have been reported. Sars (1885, Challenger Rept. Zool. 13: 228 p.) described the metacercaria of Syncoelium filiferum from the perivisceral cavity of the euphausiids Nematoscelis megalops Sars, 1883, and Thysanoessa gregaria Sars, 1883, in the South Atlantic. DoIlfus (1966, Bull. Mus. Natl. Hist. Nat. Ser. 2 38: 195-200) described Metacercaria (Gen. ?) theomonodi from some poorly preserved material amidst a collection of "copepods and chaetognaths" collected …

Harvest Mice (Genus Reithrodontomys) Of Nicaragua, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Harvest mice of the genus Reithrodontomys first were reported from Nicaragua by Oldfield Thomas (1907), who originally described Reithrodontomys sumichrasti modestus based on a single specimen from Jinotega. J. A. Allen (1908, 1910) recorded additional specimens of R. s. modestus, which still was the only species known from the country when A. H. Howell (1914) revised the genus Reithrodontomys. In his thorough review of Latin American harvest mice, Hooper (1952) added a second species, Reithrodontomys mexicanus lucifrons, to the Nicaraguan fauna, and Englert (1959) and Anderson and Jones (1960) recorded three additional kinds. The present report treats …

Bibliography Of Diseases And Parasites Of Marine Fish And Shellfish (With Emphasis On Commercially Important Species), Carl J. Sindermann

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The literature on diseases and parasites of marine animals has been accumulating at an accelerating rate in recent decades, and at a seemingly geometrical rate in the past few years. Reviews of selected aspects of the subject have appeared (Cheng, 1967; Sindermann, 1966; Sindermann and Rosenfield, 1967). References listed in these papers include a significant, but still a small part, of the available literature. With the proliferation of journals in many languages throughout the world, a complete bibliography, even in a narrow area of research, is almost an impossibility. Then too, the daily appearance of new published information represents an …

The Teaching Of Economics - A Radical Approach To Economics: Basis For A New Curriculum, Richard C. Edwards, Arthur Macewan

Department of Economics: Faculty Publications

The purpose of this paper is to outline a radical approach to economics and to suggest how several important social problems might be dealt with in that framework. Our effort to develop a new curriculum is motivated by the conviction that the orthodox approach to economics cannot deal with the important problems of modern society.

Orthodox economic analysis as presented from the elementary course through the graduate seminar is based upon an acceptance of the status quo in social relations. Microanalysis presupposes the individualistic ownership and decision-making systems typical of capitalist societies, and in this narrow context the pecuniary behavior …

Evaluating Economic Efficiency By Relative Price Analysis (Feed, Livestock And Product Sectors), J. Y. Chen, J. B. Hassler

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The specific objective of this research is to delineate efficient and inefficient economic performance areas and thereby locate the more significant problem aspects for research and program attention. Specific price analyses will be used to evaluate the price interrelationships for functional efficiency in the dimensions of space, form and time. Not only the efficient aspects of production and marketing will be indicated by the analyses but the inefficient aspects of economic performance will be stressed also. This research will provide some foundational information for making decisions, both public and private. Moreover, it will direct the attention of researchers or program …

Wheat And Feed Grains In The Great Plains And Northwest: Supply Response And Resource Use, G. A. Helmers, W. F. Lagrone

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The basic objective of the research reported here is to estimate supply response with varying product prices for wheat and feed grains. Within a framework of representative farm income maximization, changing product price relationships lead to supply adjustments which are aggregated and expressed as normative supply functions. Another objective is to analyze the resource use and net returns with varying prices for wheat and feed grains. The analysis of resources considers changes in overall levels of resources demanded in response to changing wheat and feed grain prices. Similarly, the analysis of net returns examines differences in net returns in response …

The Response Of Kentucky Bluegrass Turf To Insecticidal Treatments, E. A. Heinrichs, Leonard C. Lehman, Lloyd M. Callahan, C. J. Southards, Ellis L. Matheny

Department of Entomology: Faculty Publications

The most common insect pests of Kentucky bluegrass (Poa pratensis L.) in Tennessee are sod webworms and white grubs. Attempts to control these insects with insecticides has, at times, resulted in the entire destruction of the lawn by sod webworms. Pass (1965) has shown that applications of aldrin, chlordane, and dieldrin increased the webworm population 2-3 fold. Streu and Vasvary (1966) found the same phenomenon in chinch bug control. Both Pass and Streu believed that this population increase of the target pest may have been related to an interference in some population-limiting mechanism, such as the natural enemies, but …
