Factors Responsible For The Successful Establishment Of Exotic Avian Species In Southeastern Florida, Alison C. Rand

Vertebrate Pest Conference Proceedings: 9th (1980)

Presently southeastern Florida has at least 24 established exotic avian species from both New and Old World families. This much man-modified region of Florida is characterized by the Atlantic Coastal Ridge in Palm Beach, Broward and Dade Counties and the Florida Keys of Monroe County. Because of the draining of the Everglades to the west, the filling of the mangroves on the seaward side, and the accompanying urban-suburban sprawl, many exotic plant species have invaded the Ridge thus preparing the environment for introduced birds. The Red-whiskered Bulbul, Pycnonotus jocosus, illustrates this point. Most exotic avian species have appeared and colonized …

1979 Christmas Count

Nebraska Bird Review

Ninety-nine species (four less than last year) were reported in the 1979 Christmas Count, and one species was reported present but not seen on the count. (There was no such species reported last year.) This drop was in spite of one more count - from Kearney - this year. The number of additional races reported - three - was the same as last year. The individual count this year was 188,102 compared to 90,000 last year, and most of the increase was due to the Snow Goose and Mallard counts along the Missouri River, which in turn was due to …

Observations Of Late Fall Migratory Sandhill Cranes, Platte River, Nebraska, John G. Aronson

Nebraska Bird Review

Observations of migratory Sandhill Cranes (Grus canadensis) were made on the Platte River near Kearney, Nebraska. On 26 November 1978, night roosting in the Platte River occurred on thin ice (less than 2 cm) in open areas which were protected by riparian vegetation from cold north winds (35-40 km/hr-NNW, -10°C). Roosting Cranes were spaced very closely (less than 0.5 m) during evening and early morning hours, with increased spacing (about 1.0 m) occurring during late morning. A diagram of the roost area was prepared. The roost was located near the northern river bank in a river stretch characterized …

Twenty-One Years Of Say's Phoebes, Doris Gates

Nebraska Bird Review

Mr. and Mrs. Carl Lindeken live 10.5 miles northeast of Chadron, Nebraska, in a home with a big picture window over the kitchen sink, a window that faces the Sheridan Gates, a formation which is in Sheridan County across the Dawes County line. Outside the window is a small platform on which Say's Phoebes have nested for many years.

The first year the Lindekens were aware of Say's Phoebes was in 1958 when a pair nested in the garage, a building which is attached to the house. The birds were "messy" but they were allowed to remain through the summer. …

A Ground Dove At Desoto Nwr, Loren Padelford, Babs Padelford

Nebraska Bird Review

A Ground Dove was sighted at DeSoto National Wildlife Refuge on 18 November 1979, for about ten minutes around 11 AM, in the hedgerows opposite the entrance to the nature trail, south of the swimming beach.

It was a small dove, only slightly longer but chunkier than Tree Sparrows sitting in the same small tree. There was gray scalloping on the head and breast, the eye was dark, the beak light colored at the base, with the rest appearing dark. The wing was grayish with black speckling from shoulder to tip. We noticed a short tail when the bird was …

Stretching The Mouse Control Dollar, John E. Crumpacker

Eastern Pine and Meadow Vole Symposia

One of the biggest problems In our mouse control program at H. F. and T. B. Byrd, Inc. in Timberville, Virginia Is keeping a palatable bait before the voles until the bait can be accepted. For years we used labor needed for pruning to place an expensive bait only to be impeded by wet weather that molded the bait.

This year an effort is being made to keep the bait in good condition and before the target animal for a longer time. We cut old car tires (not steel belted) given to us by a local distributor and rented his …

Notes On The Natural History Of Bats From Badlands National Monument, South Dakota, John P. Farney, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Little has been published on the mammalian fauna of Badlands National Monument, a unique ecological area that encompasses parts of Jackson and Pennington counties in South Dakota. By way of example, although five species of bats are herein recorded from the Monument, only one has been reported previously - see Jones and Choate (1978), who listed two specimens of Myotis thysanodes pahasapensis from the Cliff Shelf area. Jones and Genoways (1976b), however, did report several other species from badland areas not far distant from the boundary of the Monument.

In 1970, under sponsorship of the Badlands Natural History Association and …

Blackbirds And Corn In Ohio, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Damage to corn by blackbirds (Icteridae) has been an economic problem throughout historical times in North America. Ohio, with the highest nesting season population density of red-winged blackbirds (Agelaius phoeniceus) in North America and large acreages of corn, has been a key state in this conflict. Survey of damage from 1968 to 1979 revealed that blackbirds annually destroyed less than 1% of the corn crops in Ohio, a 4- to 6-million dollar loss at 1979 prices. This total dollar loss is somewhat misleading because of the uneven distribution of damage among fields. Over 97% of the cornfields in …

Access Of Compounds To The Vomeronasal Organ In Pine And Meadow Voles, Charles J. Wysocki, Gary K. Beauchamp, Susan Erisman

Eastern Pine and Meadow Vole Symposia

Neuroendocrine responses play a critical role in reproduction in every mammalian species, including voles (Richmond S. Stehn, 1976). Disruption of these normal responses can result in: (1) abnormal sexual maturation; (2) abnormal or absent female cycles; (3) pseudopregnancy; (4) blocked pregnancies; or (5) the total absence of courtship and mating. Each of these factors in turn plays a considerable role in population dynamics, especially population density. Therefore, mechanisms which disrupt normal neuroendocrine function could affect population dynamics and reduce population density by affecting changes in one or many of these reproductive processes.

Initial Results Of Chemical Inhibitors And Photoperiodic Influences On Growth And Reproduction In Microtus Pennsylvanicus, Jack A. Cranford, David H. Pistole, Terry L. Derting

Eastern Pine and Meadow Vole Symposia

Recently Berger et al. (1977) have demonstrated reproductive in¬hibition in Microtus montanus as a result of specific plant compounds in natural vegetation. Naturally occurring cinnamic acids and their related vinyl phenols have been demonstrated to have marked effects on uterine weight, inhibition of follicular development and cessation of breeding activity. Compounds having antigonadotrophic and antithryo-tropic activities have been identified in a wide variety of plants (Chury 1967). Bickoff et al. (1959) report that alfalfa contained a non-estrogenic compound which would over ride the estrogenic effect of the plant estrogen coumestrol. Adler (1962) demonstrated that a non-estrogenic compound in alfalfa could …

Induction Of Abortion By Strange Males In Pine Vole Females That Are: 1) Ten Days Pregnant Or 2) Pregnant And Lactating, Margaret H. Schadler, Barbara J. Gauger

Eastern Pine and Meadow Vole Symposia

Pregnant voles react to the presence of unfamiliar males by aborting the offspring they are carrying, entering estrus and mating with these new males. This phenomenon was first described in pine voles by Marks and Schadler (1979). At that time we reported that 84% of females that were four days along in their first pregnancy were induced by strange males to reject their embryos. These findings encouraged us to continue our investigations and this paper reports results on the abortion response caused by strange males in females ten days along in their first pregnancy (Experiment I) and on experienced pine …

Results Of A Bioassay Technique For Ground-Sprayed Rodenticides, David H. Davis, William T. Sullivan Jr., Don H. Hayne

Eastern Pine and Meadow Vole Symposia

A laboratory test of toxicity to voles of toxicants sprayed. on a soil substrate was used. to test brodifacoum, chlorqphacinone and. endrin against pine voles. By this test, endrin was not as effective against meadow voles as against pine voles.

Current Research Related To Pine And Meadow Vole Damage Control, Mark H. Merson, Ross E. Byers

Eastern Pine and Meadow Vole Symposia

This paper will outline some of the research related to pine and meadow vole damage control which is currently underway at the Winchester Fruit Research Laboratory and outline some of the areas which we will be pursuing in the future. One question which must be answered whenever a chemical is used to control a pest organism is how that chemical is impacting non-target organisms. A study was initiated in the fall of 1979, with the objective of determining by use of radiotelemetry the fates of birds of prey in the vicinity of orchards treated with Brodifacoum, an anticoagulant rodenticide. A …

Field Evaluation Of Candidate Rodenticide, Milo E. Richmond, Pamela N. Miller

Eastern Pine and Meadow Vole Symposia

During autumn of 1978 and 1979 the New York Cooperative Wildlife Research Unit continued its program of research and management aimed at the pine vole (Pitymys pinetorum) and meadow vole (Microtus pennsylvanicus). Two herbicides, Ammate-X (E.I. Dupont de Nemours) and Kerb (Rhom S Haas Corp.) along with 4 candidate rodenticides, Bromadiolone and Chlorophacinone (Chempar Inc.), Volak (I.C.I. Chemicals Inc.) and zinc phosphide (Bell Laboratories Inc.) were tested in both orchard and laboratory situations. This work is being conducted in conjunction with a separate research unit project aimed at evaluating the potential of using populations of the …

Disposition Of The Endrin Rpar, Lawrence S. Ebner, Harvey S. Gold

Eastern Pine and Meadow Vole Symposia

Following a comprehensive three-year Rebuttable Presumption Against Registration ("RPAR") review of endrin, on July 25, 1979 the U.S. Environmental Protection Agency announced its decision to continue federal approval of endrin for control of pine voles in the East and meadow voles in the West among other uses. See 44 Fed. Reg. 43,637-8. The Agency concluded that with additional safety precautions and procedures, endrin can be applied safely and effectively, and that the benefits of usage outweigh any risks. The stringent new safe¬guards being required by EPA, including new usage restrictions and directions, equipment specifications, and warnings to female applicators, are …

Movement Types And Weather Correlates In Free-Ranging Meadow Voles, Dale M. Madison

Eastern Pine and Meadow Vole Symposia

Meadow voles (Microtus pennsylvanicus) were radiotracked in their natural environment from June through August 1974, 1975 and 1978. Four different types of movement were observed: residency, shifting, wandering and dispersal. Next to the residency pattern, wandering was the most common form of movement and probably was important during breeding activities. Dispersal was a rare event and is probably confused with wandering in the existing literature.

A total of 17 weather variables were analyzed for correlations with vole movement. Male voles showed a distinct tendency to move more widely during periods of dry weather. The latter was attributed to …

Pine Vole Control In 1979 Field Plots, Ross E. Byers

Eastern Pine and Meadow Vole Symposia

Broadcast treatments of Volak (Brodifacoum) applied at rates of approx. 20 lbs/acre gave 98% control of voles when active ingredient levels were from 0.005% to 0.0005% in the bait. Of the two Rozol (Chlorophacinone)formulations tested, the French (Lipha) pelleted formulation appeared to be slightly better than what is currently being marketed in the USA. The Maki (Bromodialone) bait formulated in the same wax bait carrier as the Rozol-USA gave no better control than Rozol. Ramik-Brown (Diphacinone) did not appear to be as good as the other anticoagulants tested when applied either as a broad¬cast or as a hand placed bait. …

Effective Vole Control With Zp Rodent Bait Ag, Edward F. Marshall

Eastern Pine and Meadow Vole Symposia

Since the loss of DDT, Vacor (DPL 787) and other acute rodenticides and the serious use restrictions placed upon strychnine and 1080 for field use, it has become quite apparent that control of field rodents, more particular pine and meadow voles, with standard anticoagulants has become a difficult task, and in some instances impossible.

Bell Laboratories, Inc. has chosen to take a very serious look at many of the older compounds and rework and reformulate these compounds into palatable and efficacious finished baits. After 5 years of research and development. Bell Laboratories, Inc. has recently registered, with the Environmental Protection …
