North American Migration Count (Namc)

Nebraska Bird Review

This annual event was initiated in 1992 by Jim Stasz, Coordinator, P.O. Box 71, North Beach, MD 20714. It is not associated with any national organization. Some of its goals, presented in the NAMC Newsletter, January 1993, are as follows:

* to obtain a "snapshot" of the progress of spring migration;

* to obtain information on the abundance and distribution of each species;

* to initiate more participation among birders within a a state and between states;

* to aid in the organization and centralization of data.

The NAMC is patterned after the Christmas Bird Count with some differences. The …

Ruff and Godwits. On April 19, 1994, I discovered a red-phased Ruff (Philomachus pugnax) in alternate plumage at the Sacramento Wildlife Management Area in Phelps County. It was feeding with a flock of Hudsonian Godwits (Limosa haemastica) and Marbled Godwits (Limosa fedoa) in a flooded marshy area. The Ruff was easily recognized and required little effort to identify. I observed and photographed it for about one hour in the early evening, using a Canon AE-1 and my Kowa TSN-4 with a 1200 mm photo attachment as a lens. I was unable to locate …

Spring Field Report, March-May, 1994, W. Ross Silcock

Nebraska Bird Review

INTRODUCTION

The amount of work reporters put into their reports is tremendous. Putting the information into a readable format which preserves it for future use is a challenge, but always interesting. Reporters can report on their own forms if preferred; some do now, often because of computerized record-keeping systems. I [Ross Silcock] enter the data into my computer, and so almost anything is fine, as long as I can read it. It is not necessary to list every species, although it is difficult to know whether your dates of arrival, high counts, etc. are significant until compared with the others …

The General Adaptation Syndrome In Gerbillus, Bridget L. Moore

McCabe Thesis Collection

The General Adaptation Syndrome or the G.A.S. is the term applied to collective responses to physiological stress. It is initiated by any disturbance in the normal balance of the body functions. These responses affect humans, monkeys, and other animals. The three main physiological changes which occur as a result of stress are enlarged adrenals, shrunken lymphatic organs, and bleeding gastrointestinal ulcers. There are also concomitant changes in the hematocrit and the formed elements of blood. In particular, there is usually a decrease in lymphocytes and eosinophils accompanied by the increase in neutrophils and platelets.

Stress is defined as pressure, or …

Beaver Recolonization In South-Central Maine, Laurence Lisle Ii

Electronic Theses and Dissertations

Following a long absence due to over-trapping, beaver (Castor canadensis) recolonized most of their continental range during the middle of the 20th century. The spread of beaver across the landscape was revealed by the emergence of beaver-created wetlands, or flowages. Based on the appearance of flowages on aerial photographs from 1939, 1957, 1974, and 1991, I documented the return of beaver to a 105 km^ watershed in south-central Maine. I sought to determine if certain wetland characteristics—area, perimeter to dam length (p/d) ratio, and watershed size—influenced the order in which sites were occupied by beaver. Also, to gauge the effect …

Water-Nymphs Of The Platte, Patricia W. Freeman, Keith Perkins

University of Nebraska State Museum: Mammalogy Papers

Little known, but hauntingly beautiful and valuable to the environment as well, clams and mussels inhabit many Nebraska lakes and rivers. In the first survey of the entire Platte River, the authors found 11 species.

We surveyed mollusks (clams and snails) of the Platte River during the summers of 1990 and 1991. With the exception of the Big Bend reach of the river in Dawson, Buffalo, and Hall counties, no mussels were found in the river's main channel. But in backwaters, lakes and sand-pits along the river, we found 11 species of mussels at 49 different sites from east to …

A Study Of The “Iron Ridge” Mine: An Excerpt From When Iron Was King In Dodge County, Wisconsin, George G. Frederick

Field Station Bulletins

Mining began at the Iron Ridge Mine (now commonly called Neda Mine) in 1849. The ore is relatively concentrated (nearly 55% iron by weight) and was easily mined initially because some deposits were surficial and of a loosely-cemented granular structure. In the 1850's Byron H. Kilbourn (twice mayor of Milwaukee) purchased most of the land surrounding a competitor's open pit mine, and in 1864 his own Swedes Iron Co. began underground mining. The period from 1850 to 1890 was a period of intense railroad construction in the United States, so there was a high demand for iron from this mine. …

Fall 1993 Occurrence Report (July 1-December 31)

Nebraska Bird Review

This is the last report to be presented for a 6-month period in lengthy tables because, beginning with this issue, Ross Silcock and Richard C. Rosche will have quarterly reports in text form. Their willingness to undertake this major project is greatly appreciated. There is some overlap between the information for December in the two reports because their first quarterly report includes December 1993 through February 1994. However, any descriptive observations they included for December are not repeated in this report.

A total of 273 species plus two sightings (swan and meadowlark) not assigned to species were observed in 24 …

Notes On Bird Sightings In Nebraska From Nebraska Bird Review (March 1994)

Nebraska Bird Review

Burasian Wigeon. On March 10, 1994, I discovered a male Eurasian wigeon (Anas penelope) just north of the Johnson Waterfowl Production Area in Phelps County. It was in a flock of approximately 200 puddle ducks, but primarily associated with six American Wigeons (Anas americana). The bird was distinctive and easily identified. A modest photograph has been sent to the NOU Records Committee.

After volunteering to gather data and Write a series of seasonal summaries for The Nebraska Bird Review, I was surprised that my offer was accepted and now the time has come already for the first report. I asked for comments and suggestions from contributors to the traditional six-month "spring" and "fall" Occurrence Reports and received many helpful ideas. The biggest concern was the possible loss of accessibility to data on a county-by-county basis. I do have the information entered into a database so that it can be accessed by county, and would be happy to respond to any requests for …

Homosexual Copulations By Male Tree Swallows, Michael P. Lombardo, Ruth M. Bosman, Christine A. Faro, Stephen G. Houtteman, Timothy S. Kluisza

Peer Reviewed Publications

Homosexual courtship behavior in non-human animals is well known (Ford and Beach 1980) and occurs in a wide variety of taxa. However, homosexual copulations, especially between males, are less well known. In birds, males mounting other males have been observed in the colonially breeding Cattle Egret (Bubulcus ibis) (Fujioka and Yamagishi 1981) and Common Murre (Uria aalge) (Birkhead et al. 1985, Hatchwell 1988). Neither Fujioka and Yamagishi (1981) nor Birkhead et al. (1985) and Hatchwell (1988) reported whether cloacal contact occurred during their observations of male-male mountings. Here we describe homosexual copulations by male Tree Swallows …

Barn Owl (Tyto Alba) Food Habits In West-Central Arkansas, R. M. Huston, Thomas A. Nelson

Journal of the Arkansas Academy of Science

This study was conducted on Holla Bend National Wildlife Refuge in west-central Arkansas to investigate the food habits of the common barn owl (Tyto alba). Three hundred thirty-eight pellets were collected from four barn owl nest boxes yielding the remains of 1003 individual prey items. Hispid cotton rats (Sigmodon hispidus) were eaten most frequently, comprising 46.8% of the diet by frequency. Results of this study are compared with those from other Arkansas ecoregions to assess regional variation in the diet of this endangered species.

TERRAPENE CAROLINA CAROLINA (Eastern Box Turtle). REPRODUCTION. Female Terrapene carolina containing oviductal eggs have been recorded in Virginia from 26 May to 25 July (Mitchell, in press. The Reptiles of Virginia. Smithsonian Inst. Press, Washington, D.C.). Other reports of reproduction in Terrapene (see list in Ernst and McBreen 1991. Cat. Amer. Amphib. Rept. 512.1-512.13) indicate that nesting occurs in late spring and early summer throughout its range.

Quantification Of Settlement And Recruitment Processes In Bivalve Mollusks, Patrick Kelly Baker

Dissertations, Theses, and Masters Projects

Studies were carried out to quantify abundance, mortality, and variability in these parameters, during settlement and recruitment of bivalve mollusks, using the oyster, Crassostrea virginica, as a primary model species. Most work was undertaken in the York River, Chesapeake Bay, Virginia, with additional work in the Indian River, Florida. The period chosen, in the bivalve early life history, was from the late planktonic larva to the early benthic juvenile. Studies were designed to specifically examine (a) abundance of late-stage larvae in the plankton, (b) the relationship between larval abundance and settlement, and (c) mortality immediately following settlement. Variability in abundance …

Age, Growth And Population Dynamics Of The Sandbar Shark, Carcharhinus Plumbeus, At Different Population Levels, Thomas R. Sminkey

Dissertations, Theses, and Masters Projects

The objectives of my research were to test the hypothesis that compensatory (density-dependent) growth of sandbar shark (Carcharhinus plumbeus) occurred after severe population reduction, to describe the juvenile sandbar shark fauna present in the Chesapeake Bay during 1980-81 and 1990-93, and to perform demographic analyses to examine potential population growth. Age and growth of sandbar sharks were investigated by counting rings in vertebral samples collected in 1980-81 and 1991-92. Age at maturity was 15-16 years for both sample periods and both sexes. For sexes combined, the von Bertalanffy growth parameters were L&\sb{lcub}\infty{rcub}& = 199 cm precaudal length (PCL), K = …

Predator Deterrence In The Central Newt, Notophthalmus Viridescens Louisianensis (Wolterstorff) With Notes On Salamander Antipredator Strategies, Malcolm Mccallum

Masters Theses

The effectiveness of the skin secretions of Notophthalmus viridescens as a predator deterrent has been well documented. Still, there have been documented cases of predation on this salamander. This study investigates the ability of a variety of herptiles to feed on N. viridescens louisianensis.

In the first experiment, plethodonts and efts were fed on alternate weeks to snakes. Latency of response, anatomical location of predator attack, and behaviors displayed by predators and prey were recorded during each trial.

In the second experiment, tongue flick frequency by T. sirtalis to the essence of live N. viridescens louisianensis, Eurycea cirigerra …
