Spring Field Report, March-May 1995, W. Ross Silcock
Spring Field Report, March-May 1995, W. Ross Silcock
Nebraska Bird Review
I want to thank the contributors (I think!) for their hard work and supplying me with some 2750 records from which to distill this rather lengthy report. Everything submitted is potentially valuable; my only comment is that brief details on unusual observations such as early or late dates, etc. as well as fuller descriptions of rarities should be provided. It is noteworthy that we have almost as many reporters from the panhandle as from eastern Nebraska.
The highlights of this season were varied. In general, there were few record early dates; indeed, most arrival dates were a little later than …

Daffy But Dapper: A Serious Approach To The Comical-Looking Ruddy Duck, Paul A. Johnsgard
Daffy But Dapper: A Serious Approach To The Comical-Looking Ruddy Duck, Paul A. Johnsgard
Papers in Ornithology
The punk rock star of waterfowl, a male Ruddy Duck displays an assortment of odd attributes, including a blue bill, stiff, spiky tail, and horns on its head. The instinctive attraction and fascination in reaction to the sight of a Ruddy Duck in breeding condition is perhaps as hard to understand as a teenager's compulsive reverence to some rock star. The Ruddy Duck has a football player's neck that is at least half again too large for its body, a dumpy body that is both shaped and colored like a partly flattened and rusty tin can, and an array of …

Phylogenetic Reanalysis Of Strauch's Osteological Data Set For The Charadriiformes, Philip C. Chu
Phylogenetic Reanalysis Of Strauch's Osteological Data Set For The Charadriiformes, Philip C. Chu
Biology Faculty Publications
Strauch's (1978) compatibility analysis of relationships among the shorebirds (Charadriiformes) was the first study to examine the full range of charadriiform taxa in a reproducible way. Subsequently Mickevich and Parenti (1980) leveled serious charges against Strauch's characters, method of phylogenetic inference, and results. To account for these charges, Strauch's characters were re-examined and recoded, and parsimony analyses were performed on the revised matrix. A parsimony analysis on 74 taxa from the revised matrix yielded 855 shortest trees, each length = 286 and consistency index = 0.385. In each shortest tree there were two major lineages, a lineage of sandpiper-like birds …

Egg Removal By Brown-Headed Cowbirds: A Field Test Of The Host Incubation Efficiency Hypothesis, Douglas R. Wood
Egg Removal By Brown-Headed Cowbirds: A Field Test Of The Host Incubation Efficiency Hypothesis, Douglas R. Wood
Masters Theses
Obligate brood parasites, like the Brown-headed Cowbird (Molothrus ater), lay their eggs in the nests of host species, usually to the detriment of the host's reproductive effort. In addition, Brown-headed Cowbirds often remove one or more host eggs near the time of parasitism. Although several hypotheses exist, the adaptive significance of egg removal has not been clearly established. Peer and Bollinger (in press) proposed the host incubation efficiency hypothesis which states that the number and size of host eggs influences the incubation efficiency of a parasitic egg. Thus, host egg removal by cowbirds should increase the parasitic egg's …
Reproductive Success Of Grassland Birds At East-Central Illinois Airports, Eric L. Kershner
Reproductive Success Of Grassland Birds At East-Central Illinois Airports, Eric L. Kershner
Masters Theses
We determined the densities and reproductive success of birds on airport grasslands in east-central Illinois. Seven airports were sampled between 10 April and 15 August 1994 in Clark, Coles, Crawford, Douglas, Edgar, Macon and Richland counties. Nineteen species were detected on the airport grasslands and 147 nests were found representing six different species. Eastern meadowlarks (Sturnella magna) were the most abundant nesting species found; 105 out of the 147 nests (71%). Other nesting species included: grasshopper sparrow (Ammodramus savannarum), savannah sparrow (Passerculus sandwichensis), red-winged blackbird (Agelaius phoeniceus), song sparrow (Melospiza melodia) and horned lark (Eremophilia alpestris). Overall nest success was …

Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials
Executive Summary
This Action Plan covers the world's partridges, quails, francolins, snowcocks and guineafowl, a group of birds from the order Galliformes comprising 141 species according to the most recent taxonomic consideration (Sibley & Monroe 1990), plus one further species newly discovered in 1991 (Dinesen et al. 1994). These birds attract considerable interest throughout the world on account of their importance in ornamental collections, as food sources, as sporting quarry, as indicators of the health of ecosystems and as objects of great beauty. The objectives of this document are to identify the most threatened species and sub-species within this group …

Executive Summary
Two hundred and forty-seven galliform taxa (subspecies, groups, or species) were considered by the Galliform Conservation Assessment workshop. Two extinct taxa were not considered. Of the 247 taxa, 91 (37%) were assigned to one of three categories of threat, based on the Mace-Lande criteria:
Critical, 5 taxa
Endangered, 26 taxa
Vulnerable, 60 taxa
Secure, 145 taxa
Unknown, 11 taxa
Three of the 247 taxa (1%) were recommended for Population and Habitat Viability Assessment (PHVA) workshops.
Recommendations for future action were made for 168 taxa in the following categories:
Stopping the bird trade, 7 taxa
Intensive management of the …

Beguiled By Birds: A Profile Of Paul Johnsgard, James L. Hayward, Paul A. Johnsgard
Papers in Ornithology
“I spent the first thirty years of my life learning to be a scientist, and the next twenty-five years of my life trying to become a humanist and an artist." Paul Johnsgard immerses himself in several worlds, but for the eclectic teacher, writer, artist, and scientist, these worlds merge in a burst of feathered movement, color, and shape. Johnsgard is beguiled by birds. As a professor of biological sciences at the University of Nebraska with full teaching responsibilities, Johnsgard has managed to write at least one or two books on birds each year. In 1986 I asked him if he …

Should Australia Export Its Native Birds?, Ross Kingwell
Should Australia Export Its Native Birds?, Ross Kingwell
Biosecurity Research Articles
Commercial export from Australia of native birds, wild or captive bred, is prohibited. This paper firstly describes the current legislation and regulations that restrict the export of native birds and discusses why governments have adopted such a regulatory approach to bird species preservation. Secondly, the paper reviews the debate concerning the export ban, pointing out strengths and weaknesses in arguments and indicating the important role of CITES. Lastly, the paper outlines a new case for a conditional lifting of the ban, whereby DNA fingerprinting is used to establish transferable property rights to overcome a main source of market failure in …

Breeding Patterns Of Eastern Phoebes In Kansas: Adaptive Strategies Or Physiological Constraint?, Michael T. Murphy
Breeding Patterns Of Eastern Phoebes In Kansas: Adaptive Strategies Or Physiological Constraint?, Michael T. Murphy
Biology Faculty Publications and Presentations
Data were collected on annual (1980-1983) and seasonal (spring vs. summer) variation in reproduction by the double-brooded Eastern Phoebe (Sayornis phoebe) to test the proposal that phoebes modify reproductive patterns on a seasonal basis and switch from being brood survivalists in spring to brood reductionists in summer. Clutch size did not differ between spring and summer broods nor among years, but spring nests fledged one more nestling than summer nests. In 1981 breeding began earlier, eggs were larger, and nestlings grew faster than in all other years. Clutch size and egg mass within spring clutches increased seasonally. Egg mass was …
