Common Goldeneye: Notes On Nebraska Fauna, Paul A. Johnsgard

Papers in Ornithology

0NE OF THE rewards for braving the remnants of a Nebraska winter by venturing out to newly thawed reservoirs, lakes and sandpits is the prospect of seeing a flock of common goldeneyes. Hard on the heels of winter, goldeneyes begin moving out of their wintering areas in the central and southern Great Plains and testing the waters to the north as as they become partially ice-free. Fair numbers of birds, sometimes in the thousands, often winter in western Nebraska, especially along the North and South Platte rivers, and in adjoining areas of eastern Wyoming and Colorado, but very few winter …

Foraging Behavior And Switching By The Grasshopper Sparrow Ammodramus Savannarum Searching For Multiple Prey In A Heterogeneous Environment, Anthony Joern

School of Biological Sciences: Faculty Publications

Switching among four alternative grasshopper species by the grasshop- per sparrow (Ammodramus savannarum) through frequency-dependent predation was ex- amined. Grasshoppers were presented against a heterogeneous natural background in an outdoor aviary where total density was held constant but relative density of each grasshopper species varied. Switching among prey, primarily between two of the four species, and inter-bird variability in switching was observed. Species-specific prefer- ences and interactions among the alternative grasshopper species affected the final diet choice as one grasshopper species was always preferentially selected and another disregarded independent of changes in relative density. Attributes of avian foraging behavior, including: …

Key To Acanthocephala Reported In Waterfowl, Malcolm Edwin Mcdonald,

United States Fish and Wildlife Service: Publications

This is the third part of a continuing series on helminths reported in waterfowl (McDonald 1974, 1981). Coots and moorhens (in Family Rallidae, Order Gruiformes) are included with the Anatidae of Anseriformes. The goal of these studies is complete coverage of waterfowl helminths of the world, although the original incentive-inadequate knowledge of the parasites of North American waterfowl- is less true now. World coverage is desirable because the world distribution of the family, tribes, and even many species of waterfowl often results in world distribution of parasites. The format of this key follows that of the others in the series: …

A Nebraska Specimen Record Of Clark’S Grebe, Aechmophorus Clarkii (Lawrence), Thomas E. Labedz

Nebraska Bird Review

Clark’s Grebe, formerly known as light-phase Western Grebe (Aechmophorus occidentalis clarkii), was elevated to full species status (A. clarkii) in 1985 (American Ornithologists’ Union (AOU) 1983, 1985). This paper presents the first recorded occurrence in Nebraska of Clark’s Grebe and is documented with a specimen. Identification of Clark’s Grebe in the field is discussed, and a comparison is made of the Nebraska specimen with specimen s reported in recent literature.

Diving Birds Of North America: 5 Comparative Pair-Forming And Copulatory Behaviors, Paul A. Johnsgard

Diving Birds of North America by Paul A. Johnsgard

All species of loons, grebes, and auks are monogamous, with adults forming strong pair bonds that are established or reestablished each year, probably during the spring prenesting period. The extent of remating by birds mated the previous year in these groups is still largely undocumented, though at least in alcids it is fairly high, given the relatively long life-spans and the tendencies of the birds to return year after year to essentially the same territory and sometimes to the same nest site. Such conditions would promote reestablishment of contracts between previously paired birds, since it is not believed that in …

Diving Birds Of North America: Species Accounts — Loons (Gaviidae), Paul A. Johnsgard

Diving Birds of North America by Paul A. Johnsgard

Loons are large diving birds having long, straight, and acutely pointed bills, with feathers covering the lores (region between eye and bill) and extending to the linear nostrils. There are 10 functional primaries and 22–23 secondaries, the inner secondaries shorter than the primaries. Molting of the remiges (flight feathers) is simultaneous, and the wings are not used for underwater propulsion. The 16–20 rectrices (tail feathers) are short and stiff. The body feathers are shiny and water-resistant; aftershafts and adult down feathers are present. The legs are set extremely far back on the body, making standing very difficult and walking or …

Diving Birds Of North America: Species Accounts — Grebes (Podicipedidae), Paul A. Johnsgard

Diving Birds of North America by Paul A. Johnsgard

Grebes are small to medium-sized diving birds having bills that vary from short and rather blunt tipped to long and acutely pointed, with bare lores and head feathers not extending to the linear or oval nostrils. There are 11 functional primaries and 17–22 secondaries, the inner secondaries longer than the primaries. Molting of the primaries is simultaneous; the wings are not used for underwater propulsion, which is provided by the feet. The rectrices are soft, rudimentary, and hidden. The body feathers are small, water-resistant, and shiny. Aftershafts and adult down feathers are present. The legs are set extremely far back …

Diving Birds Of North America: 3 Comparative Egocentric And Locomotory Behaviors, Paul A. Johnsgard

Diving Birds of North America by Paul A. Johnsgard

As used here, "egocentric behavior" means those categories of individual survival and maintenance behaviors that are exclusive of such social interactions as aggressive, sexual, and parental behaviors, which will be considered in detail in the individual species accounts and also will be separately summarized in chapter 5. A discussion of the ecological aspects of foraging behavior will also be deferred until chapter 4, though behavioral aspects of underwater locomotion and prey catching will be considered here.

Diving Birds Of North America: 1 General Attributes And Evolutionary Relationships, Paul A. Johnsgard

Diving Birds of North America by Paul A. Johnsgard

Loons, grebes, and auks comprise a rather large number of species of aquatic diving birds that are fairly unfamiliar to most people, inasmuch as they tend to spend much of their time well away from shore and, when approached on the water, usually dive inconspicuously and reappear a considerable distance away. Thus in many areas grebes, simply called "helldivers," are often confused with coots or even diving ducks. Many people know loons only by their wild, penetrating cries and romantically associate them with northern woods and lakes, while auks are symbolic of arctic coastal cliffs. But ornithologists can find fascinating …

Diving Birds Of North America: 4 Comparative Diets And Foraging Ecologies, Paul A. Johnsgard

Diving Birds of North America by Paul A. Johnsgard

Auks, loons, and grebes are birds whose anatomies and behaviors have been sharply influenced by their foraging niche adaptations. In each species these have evolved through natural selection over extended periods of geologic time as a reflection of available food resources, the presence of competing species, and the limitations on innate variations in anatomy, physiology, and behavior imposed by available genetic mutations and recombinations. To a very considerable degree the auks, loons, and grebes seem to have adjusted to the effects of interspecific competition by evolving differences in bill shape and body size that sometimes open specific new foraging niche …

Diving Birds Of North America: Species Accounts — Auks (Alcidae), Paul A. Johnsgard

Diving Birds of North America by Paul A. Johnsgard

Auks are small to medium-sized diving birds having bills that are variably pointed and compressed but never acuminate and are sometimes covered with colorful horny sheaths in breeding adults. Feathering densely covers the lores and often extends to the nostrils, which vary from linear to oval. There are 10 functional primaries and 15–19 secondaries; the greater secondary and primary coverts are usually lengthened. Molting of the primaries is usually simultaneous but is gradual in some species; the wings are used for underwater propulsion, and the feet are then used mainly for steering. The 12–18 rectrices are short and normal in …
