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 …

Crowding Among Hunter-Gatherers: The !Kung Bushmen, Patricia Draper

Department of Anthropology: Faculty Publications

Highly crowded living conditions exist among the !Kung Bushmen, hunter-gatherers who live on the edges of the Kalahari Desert in Botswana and South-West Africa. The !Kung appear to be crowded by choice, and biological indicators of stress are absent. Data indicate that residential crowding alone does not produce symptoms of pathological stress.

Excavations At Korucutepe, Turkey. Part Ii: The Fortification Wall, Carol Bier

Textile Research Works

Excavations at Korucutepe have brought to light a fortification wall of a type common in Anatolia during the second millennium B.c. The wall had been exposed in places by bulldozing operations for a government farm. Excavation revealed a plan consisting of a curtain wall with a double stone foundation (see fig. 7). Square towers project at intervals where the direction of the wall changes. Adjacent to two of the towers is a passageway, one on the south side of the mound, one on the northeast, leading out from the city. There is no indication of any cross walls, or casemates, …

Nongeographic Variation In The Long-Nosed Bat, Choeroniscus Intermedius, Hugh H. Genoways, Robert J. Baker, Bernard Wyatt

University of Nebraska State Museum: Mammalogy Papers

Of the 12 measurements analyzed, only length of tail exhibited enough individual variation to warrant its deletion in analysis of geographic or interspecific variation in the genus Choeroniscus. Also, because of the difficulty in consistently taking the measurement, we also suggest elimination of postorbital constriction.

Specimens of Choeroniscus intermedius were found to exhibit significant secondary sexual variation in five of the 12 measurements studied. Therefore, it is clear that males and females should be separated in analyses of variation within members of the genus. Females were found to be the larger in 10 of the 12 measurements--similar to the …

Reproductive Efficiency Of Purebred And Crossbred Dairy Cattle, R. E. Mcdowell, J. A. Velasco, L. Dale Van Vleck, J. C. Johnson, G. W. Brandt, B. F. Hollow, B. T. Mcdaniel

Department of Animal Science: Faculty Publications

Nine measures related to breeding efficiency were used for comparisons among purebred Ayrshires, Brown Swiss, Holsteins, and Jerseys and between purebreds and 32 crossbred groups representing 2-breed, 3-breed, 5/8, and backcrosses by purebred sires and progeny of crossbred sires. There were four herds with Holsteins common to all, Brown Swiss and Jerseys in three herds and Ayrshires in one herd. Four 2-breed, two 3-breed, and two backcross groups were common to two or more herds. Among purebreds, breed effects were significant in 16 of 72 tests, but there was no consistent trend favoring one breed. Generally, Jerseys were better than …

Evaluation Of Purebreds And Two-Breed Crosses In Swine: Reproductive Performance, R. K. Johnson, I. T. Omtvedt

Department of Animal Science: Faculty Publications

The data included records on 440 purebred sows and gilts of Duroc, Hampshire and Yorkshire breeding mated in all combinations to produce purebred and two-breed cross litters. A total of 119 purebred gilts (39 with purebred litters and 80 with crossbred litters) were slaughtered 30-days postbreeding and their reproductive tracts evaluated for number of corpora lutea and early embryo development. Farrowing records included 89 purebred and 161 two-breed cross litters produced at the Ft. Reno Experiment Station during the spring and fall of 1971 and the summer of 1972.

Tool-Making And Tool-Using In The Northern Blue Jay, Thony B. Jones, Alan Kamil

Papers in Behavior in Biological Sciences

Laboratory-raised Northern blue jays (Cyanocitta cristata) have been observed tearing pieces from pages of newspaper and utilizing them as tools to rake in food pellets which were otherwise out of reach. The frequency of this behavior was dependent upon the motivational state of the jay and the presence of food pellets.

Annotated Checklist Of Mammals Of The Yucatan Peninsula, Mexico. I. Chiroptera, J. Knox Jones Jr., James Dale Smith, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Our field investigations on the Yucatán Peninsula were initiated in the summer of 1962 when two field parties from the Museum of Natural History at the University of Kansas visited the area. One field party consisted of W.E. Duellman and six students enrolled in a summer field course in vertebrate zoology; the other party was composed of the senior author and four students who were conducting a survey of Middle American terrestrial vertebrates and their ectoparasites. Some of the data relative to ectoparasites obtained during this study have appeared in the publications of Emerson (1971), Kohls et al. (1965), Loomis …
