Bird Foraging And Its Economic Effect In The Paddy Fields Of Bangalore (India), Shakunthala Sridhara, M.V.V. Subramanyam, R. V. Krishnamoorthy

Bird Control Seminars Proceedings

Birds are often serious pests of rice. The small size of this cereal at all stages of its ripening makes it attractive for the small, seed-eating birds. Considerable damage also is inflicted during early stages of growth when germinating seedlings are depredated by grainivores, and several species of aquatic birds trample the fields in search of food. The migratory blackbirds (Agelaius species and others) eat various grains across the U.S.A. and Mexico, while huge numbers of red-billed weaver bird (Quelea quelea) account for grain losses up to 20% in several rice-growing African countries (Efferson, 1952). Although rice …

Adjusting Bird Control Applications With Their Optimal Behaviors In Red-Winged Blackbirds, André Cyr, Carmelle Leroux, Jean-Marie Bergeron

Bird Control Seminars Proceedings

In order to improve control methods that imply giving any drug, repellent, or chemosterilant through food, we need to know where and how to offer the feeding opportunities to maximize the number of birds to be treated. Because of heavy snow cover in the winter in Quebec, spring-feeding flocks of red-winged blackbirds are predicted to be more attracted to corn fields than non-corn fields and more attracted to feeding sites where corn stems were left over from the preceding fall or where perches near the feeding stations are available. Multivariate analysis confirmed the trends predicted for 30 feeding sites. Other …

The Possible Role Of Starlings In The Spread Of Tge In Pigs, R. W. Summers, G. C. Pritchard, H. B. L. Brookes

Bird Control Seminars Proceedings

Transmissible gastro-enteritis (TGE) is an economically important viral disease of pigs in Britain, particularly in East Anglia. Starlings are often abundant at pig farms where they feed on pig food. The close association between starlings and pigs has led farmers to believe that starlings transmit TGE from one farm to another, but evidence has been circumstantial. The following study was designed to establish whether starlings do move between farms. Starlings which were wing-tagged at a pig farm were relocated at 25 other sites, including eleven other pig farms, so the possibility that starlings can transmit TGE from one farm to …

Public Relations In Environmental And Vertebrate Pest Research, Bruce A. Colvin, Paul L. Hegdal, William B. Jackson

Bird Control Seminars Proceedings

In our efforts to investigate environmental concerns, such as vertebrate pests, we as scientists too often neglect or fail to recognize the importance and value of strong public relations. Most scientists would agree that public relations and public education are honorable components of research, but time is often a precious commodity to be utilized in resolving the ecological problem under investigation. Additionally, in many situations, due either to the personality of the researcher or public sensitivity to the problem area, many scientists shy away from public interaction. In the vertebrate pest field, we often deal with ecological problems that stem …

Mode Of Repellent Activity Of Condensed Tannin To Quelea, M. H. Zeinelabdin, R. W. Bullard, W. B. Jackson

Bird Control Seminars Proceedings

Nonlethal chemical repellents are being vigorously investigated to control wildlife feeding in agriculture and silviculture and thus alleviate damages to food, feed, and fibre. Unfortunately, few effective avian repellents have emerged, partly because workers tend to be anthropomorphic in their basic assumptions about target species and repellent action (Rogers, 1978), and partly due to the lack of knowledge of the feeding behavior of the target species (McKey, 1974). Rogers (1978) advocated natural chemical defenses of plants against herbivores as starting points for studies dealing with repellent development. Rogers (1978) defined repellents as a "compound or combination of compounds that, when …

Influence Of Taste And Color Cues On Bathing By Starlings In Appetitive And Adversive Contexts: Implications For Animal Damage Control, J. Russell Mason, Russell F. Reidinger

Bird Control Seminars Proceedings

The importance of color and taste in feeding and drinking by omnivorous birds is context·dependent and influenced by learning. Here, we report three experiments designed to assess the influence of such characteristics on starlings. In Experiment 1, eight starlings were given a choice between bathing in red or plain water and 0.15 M NaCI solution or plain water. The frequencies of bathing, drinking, and preening were recorded. Red water was avoided (p < 0.05), but no preferences were observed between NaCI solution and plain water (p > 0.25). That 0.15 M NaCI was not avoided is surprising, because it is rejected by starlings when drinking. Perhaps starlings do not taste substances while bathing but continue …

Feed Losses To European Tree Sparrows (Passer Montanus) At Duck Farms In The Philippines, Justiniano L. Libay, Lynwood A. Fiedler, Richard L. Bruggers

Bird Control Seminars Proceedings

The purpose of this paper is to describe briefly the duck farm industry in the Philippines and to report preliminary findings on the problem posed by pest birds to individual farmers. The concerns of several farmers about the amounts of duck feed being eaten by Europen tree sparrows (Passer montanus) prompted this study. Wright (1973) reported that starlings (Sturnus vulgaris) caused an annual loss of about 1,000 tons of food pellets at one duck farm in Great Britain. This is one of the few references describing this type of bird pest situation of which we are …

Wintering Robins Affect Blackbird Roost Dispersal, Sally Erdman

Bird Control Seminars Proceedings

The numbers of blackbirds wintering in the north central Texas city of Denton appear to be increasing. Unusually large numbers of American robins (Turdus migratorius) in 1981-82 obstructed effective roost dispersal. Dispersal methods and procedures are described. Data are given on species composition, sex ratios, mean weights, and weight range for 2,781 birds taken January 29, 1982. Species composition and ratios are given for an additional 1,540 birds taken the following day. Current blackbird dispersal techniques are ineffective if large numbers of wintering robins are commingling with the blackbirds.

LATE WOOD DUCK BROODS. I don't know if weather affected the nesting of some Wood Ducks or not, but 8 August (1982) seems a little late for baby woodies. At the Iowa Settling Pond, there were two hens with new families; one hen had two ducklings that were about 5 to 6 days old, and another hen had a brood that was only a few hours out of the nest. The Wood Duck raises but one brood in a season in any part of its wide range, according to Bent, and has always been considered and early nester. I searched …

A Bird Control Program For Downtown Areas, Donald J. Franke

Bird Control Seminars Proceedings

Almost every major city across the United States is faced with a constant problem of large pigeon populations sharing the downtown streets and buildings with the general public. To some people this is not an objectionable thought, but those who work, live, or shop in the downtown areas realize the nuisances these birds create. Few people, however, realize the full extent of the problems caused by the birds' presence. Some of the more significant hazards are: diseases carried by the bird (Ornithosis, Encephalitis); diseases developed through their droppings (Histoplasmosis, Cryptococcosis); acidic deterioration effect of their droppings on buildings; nesting materials …

Thermal Requirements For Emergence Of Overwintered Sorghum Midge (Diptera: Cecidomyiidae), Frederick P. Baxendale, G. L. Teetes

Department of Entomology: Faculty Publications

Emergence of overwintered sorghum midges, Contarinia sorghicola (Coquillett), was monitored during 1979, 1980, and 1981. Differences in emergence times and distributions among years was a function of soil temperature and rainfall. A heat unit accumulation model incorporating a rainfall adjustment factor was developed which described adult emergence in the spring. Adult midges initiated emergence after accumulating 431 centigrade heat units (based on mean daily to-cm soil temperatures starting 1 April) above a threshold temperature of 14.8°C, whereas, 679 and 977 heat units were required for 50 and 95% emergence, respectively. Sorghum midges that overwintered in johnsongrass spikelets emerged after similar …

Factors Influencing Adult Emergence From Diapausing Sorghum Midge, Contarinia Sorghicola (Diptera: Cecidomyiidae, Frederick P. Baxendale, G. L. Teetes

Department of Entomology: Faculty Publications

Sorghum midge, Contarinia sorghicola (Coquillett) diapause was terminated in the laboratory, and factors affecting adult emergence from diapausing larvae were investigated. Temperatures in the range from 20 to 30°C were optimum for diapause termination and adult emergence. Diapausing larvae exposed to moist conditions at 30°C began to emerge as adults after 12 days of incubation. Based on adult emergence rates per day, an emergence threshold temperature was estimated to be 14.8°C. Exposure to 12 to 13 days of continuous moisture at 30°C was essential for diapause termination and adult emergence. Moisture acted to initiate diapause termination, but diapausing larvae were …
