The Evolution Of Duck Courtship, Paul A. Johnsgard 2012 University of Nebraska-Lincoln

The Evolution Of Duck Courtship, Paul A. Johnsgard

Paul Johnsgard

The courtship of ducks is unusual in several aspects. In temperate zones it generally begins very early, usually on the wintering grounds, so courtship is not a manifestation of territorial proclamation and defense as is the case with many songbirds. Nor, because of its early initiation, is courtship closely correlated with gonad growth and fertilization; rather, pair formation is normally completed prior to the period of maximum gonadal activity. Therefore, reproductive behavior in ducks may be conveniently divided into an early phase of conspicuous displays associated with actual pair formation, followed by the later and less elaborate behavior patterns concerned …

Fall Distribution Of Birds In A Palouse River Canyon, Frank B. Golley, Paul A. Johnsgard 2012 Michigan State University

Fall Distribution Of Birds In A Palouse River Canyon, Frank B. Golley, Paul A. Johnsgard

Paul Johnsgard

During the fall and winter of 1953 the writers undertook a general ecological study of a portion of the Palouse River valley, near Armstrong, Whitman County, Washington. During the course of these investigations records were kept on the numbers of birds observed and the vegetation in which they were located. It was anticipated that these observations might indicate bird-use of the major vegetational types found in the area. Several investigators (Dumas 1950; Wing 1949) have published distributional data for birds of the Palouse grassland during the nesting, period, but few have been concerned with distribution patterns during the fall migration.

Effects Of Water Fluctuation And Vegetation Change On Bird Populations, Particularly Waterfowl, Paul A. Johnsgard 2012 University of Nebraska-Lincoln

Effects Of Water Fluctuation And Vegetation Change On Bird Populations, Particularly Waterfowl, Paul A. Johnsgard

Paul Johnsgard

In recent years reclamation activities in the Columbia Basin of Washington have resulted in profound changes in the character of the entire landscape throughout this region. The present study is an attempt to clarify some of the biological effects of impoundment behind O'Sullivan Dam in the Potholes area, Grant County (Johnsgard 1955b). In this area, a large expanse of moving sand dunes and a high water table are responsible for causing the formation of numerous small water areas, or "potholes," between the dunes. The physical nature of the area and its limited potentialities have made it of little value to …


Raptors Of Nebraska, Paul A. Johnsgard 2012 University of Nebraska-Lincoln

Raptors Of Nebraska, Paul A. Johnsgard

Paul Johnsgard

Nebraska is a regular host to 17 species of hawks, as well as two eagles and eight owls. Collectively, all these impressive-looking birds are known as “raptors,” which refers to their strong, sharply decurved and pointed beaks, their sharp, curved talons and their associated predatory abilities. Hawk and eagles are often called “diurnal raptors,” since they all hunt during daylight hours, whereas most of Nebraska’s owls hunt at night and are described as nocturnal raptors. But few biological statements lack exceptions, and some owls such as the burrowing owl are daytime-hunters, and some such as the great homed owl hunt …


5 Reproductive Biology, Paul A. Johnsgard 2012 University of Nebraska-Lincoln

5 Reproductive Biology, Paul A. Johnsgard

Paul Johnsgard

The reproductive potentiaI of animal species is a compound result of numerous behavioral and physiological characteristics, most of which can be considered species-typical. These include such things as the time required to attain reproductive maturity, the number of nesting or renesting attempts per year once maturity is attained, the number of eggs laid per breeding attempt, and the number of years adults may remain reproductively active. These traits place an upper limit on the reproductive potential of a species, which is never actually attained. Rather, the actual rate of increase will only approach the reproductive potential, being limited by such …

Cranes Of The World: 2. Individualistic And Social Behavior, Paul A. Johnsgard 2012 University of Nebraska-Lincoln

Cranes Of The World: 2. Individualistic And Social Behavior, Paul A. Johnsgard

Paul Johnsgard

Like all higher organisms, cranes perform a variety of behavior patterns throughout their lives that have evolved to fulfill diverse functions. Much of their time is spent in self-directed activities necessary to maintain life and health. These individualistic or "egocentric" activities include such fundamental behaviors as breathing, eating, defecation, drinking, and sleeping or resting. Other activities, while not vital to life, are usually performed during "leisure time"; these include preening, shaking, stretching, oiling, and other actions that fall within a general umbrella of "comfort" activities. Still other activities, such as foraging and the seeking of shelter, result in aggregations of …

Ducks, Geese, And Swans Of The World: Tribe Stictonettini (Freckled Duck), Paul A. Johnsgard

Paul Johnsgard

Freckled Duck
Even more than the Cape Barren goose, the freckled duck exhibits an assortment of anatomical traits that suggest affinities with the geese and swans, in spite of a fairly typical ducklike appearance and foraging behavior. Its unpatterned downy young, its remarkably primitive syringeal structure, and its reticulated tarsus all strongly argue for the position that this species is the sole survivor of a very ancient waterfowl lineage, with no near living relatives. A detailed study of its social behavior is greatly to be desired, for like the magpie goose, it provides an unequaled opportunity to gain insight into …


Long-Tailed Jaeger Collected In Eastern Washington, Paul A. Johnsgard 2012 University of Nebraska-Lincoln

Long-Tailed Jaeger Collected In Eastern Washington, Paul A. Johnsgard

Paul Johnsgard

An adult female Long-tailed Jaeger (Stercorarius longicaudus) was collected on Potholes Reservoir. Grant County. Washington, June 27. 1953. The bird was observed resting on the water near the middle of the reservoir. and as I approached. I noticed it was unable to fly. It attempted to fly several times as I came near, but seemed too exhausted to be able to leave the water. It was readily captured and brought to shore. Although in apparent good health. it refused to eat. and died that night. The bird was skinned, and is specimen number 53-216 in the Charles R. Conner Museum, …
