Megapodes Status Survey And Conservation Action Plan, 2000-2004, René W. R. J. Dekker, Richard A. Fuller, Gilliam C. Baker, World Pheasant Association, Birdlife International, Iucn-Ssc Megapode Specialist Group Jan 2000

Megapodes Status Survey And Conservation Action Plan, 2000-2004, René W. R. J. Dekker, Richard A. Fuller, Gilliam C. Baker, World Pheasant Association, Birdlife International, Iucn-Ssc Megapode Specialist Group

Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials

Executive Summary

This Action Plan covers the megapodes, a group of Australasian ground-dwelling birds comprising 22 species found from the Nicobar Islands in the west, through Indonesia, the Philippines, and Australia, to Polynesia in the east. Their habit of nesting on or near beaches, often on small islands, makes them vulnerable to disturbance and egg collecting, and several species are greatly threatened. In 1995, the first Action Plan for the conservation of these species was published and this document provides an update on the current situation. The objectives of this document are to identify the most threatened species within this …


Historic Birds Of Lincoln's Salt Basin Wetlands And Nine-Mile Prairie, Paul A. Johnsgard Jan 2000

Historic Birds Of Lincoln's Salt Basin Wetlands And Nine-Mile Prairie, Paul A. Johnsgard

Nebraska Bird Review

The changes that have occurred in the bird life of the Lincoln area during the past century must certainly be great, but we have little evidence to document this point. There is, however, an annotated bird list from 1900 for the salt basin wetlands of western Lincoln, an area then gradually being developed for recreational use. This list was published by J. S. Hunter in the Proceedings of the First Annual Meeting of the Nebraska Ornithologists' Union (1900, 18-21). At this time, the recently impounded but still saline lake was 2 to 3 feet deep, and it covered about two …


Book Review: Birds Of The Untamed West. The History Of Birdlife In Nebraska, 1750 To 1875 By James E. Ducey, W. Ross Silcock Jan 2000

Book Review: Birds Of The Untamed West. The History Of Birdlife In Nebraska, 1750 To 1875 By James E. Ducey, W. Ross Silcock

Nebraska Bird Review

Those with an interest in the birds of the Great Plains will be familiar with Jim Ducey's Nebraska Birds: Breeding Status and Distribution, published in 1988. I was amazed then by Jim's diligence in searching a wide range of sources and compiling an exhaustive list of Nebraska breeding records organized by county. Jim's new book, Birds of the Untamed West, reflects the same dogged pursuit of obscure sources unavailable to most of us and compilation of the results. If you expect such a compilation to be dry and boring, you will be pleasantly surprised, especially if you are …


Review Of The Breeding Status Of Pinyon Jay In Nebraska, Wayne J. Mollhoff Jan 2000

Review Of The Breeding Status Of Pinyon Jay In Nebraska, Wayne J. Mollhoff

Nebraska Bird Review

The Rev. J,M. Bates (1900) was the first tQ suggest breeding by Pinyon Jays (Gymnorhinus cyanocephalus) in Nebraska when he reported, "Breeding at Holly, Sheridan Co., north of Rushville, July 15, '97." While he gave us no indication of what he saw, the date cited in the report, 15 July, should raise a cautionary flag, since by that date the young are normally 2 months past fledging and would be free-flying and moving about with the flock.

In discussing birds which breed in the state, Bruner (1901) placed the species in Part II of the list, along with …


Virginia's Warblers In Kimball County, Stephen J. Dinsmore, Joe Fontaine Jan 2000

Virginia's Warblers In Kimball County, Stephen J. Dinsmore, Joe Fontaine

Nebraska Bird Review

This fall 2000 season was marked by a very westerly flavor to the passerine migration with many sightings of western warblers, vireos, and flycatchers in western Nebraska. Most notably, Townsend's Warblers and Cassin's Vireos were seen in good numbers. Additionally, three sightings of Virginia's Warbler and five of Dusky Flycatcher added to the excitement. In this note, we report this fall's sightings of Virginia's Warbler and comment on the status of this species in Nebraska.

On 26 August 2000, Dinsmore observed a Virginia's Warbler (Vermivora virginiae) along the north side of Oliver Reservoir. He studied the bird at …


Summer Field Report, June And July 2000, W. Ross Silcock Jan 2000

Summer Field Report, June And July 2000, W. Ross Silcock

Nebraska Bird Review

I wish to remind observers to report dates of breeding evidence, such as nests with eggs and adults feeding fledglings. There is surprisingly little known about these things for Nebraska's breeding birds, even the common ones. Please report these regardless of the season!

This summer produced many interesting sightings; we'll lead off with significant breeding records: Snowy Plover provided a 2nd state breeding record; Black-necked Stilt a first for Keith Co; Acadian Flycatcher first for Thurston Co; Summer Tanager first for Otoe Co; and Eurasian Collared-Dove 3rd nesting locality, at Elmwood.

Late spring migrants included a record late Tennessee Warbler …


Black-Throated Gray Warbler At Oliver Reservoir, Stephen J. Dinsmore Jan 2000

Black-Throated Gray Warbler At Oliver Reservoir, Stephen J. Dinsmore

Nebraska Bird Review

On 1 May 1999, I was birding a point along the north shore of the lake when I encountered as small. flock of Yellow-rumped and Orange-crowned Warblers. At approximately 8:06 a.m. I was working my way through the flock when I heard a different chip note. The bird was feeding in a nearby tree, and I immediately recognized it as a male Black-throated Gray Warbler. I was able to study the bird at close range until 8:16 a.m. The bird was roughly the size of an Orange-crowned Warbler and was noticeably smaller and shorter-tailed than a Yellow-rumped Warbler. The head …


Nebraska Ornithologists' Union Fall Meeting Report, 1999 Jan 2000

Nebraska Ornithologists' Union Fall Meeting Report, 1999

Nebraska Bird Review

The Nebraska Ornithologists' Union Fall meeting took place once again at the Nebraska National Forest at Halsey between October 8 and 10. The following table represents the count, 108 species in all, for the five areas listed. As usual, the counts for Thomas and Blaine counties exclude the National Forest land in both counties.


First Record Of A Brambling For Nebraska, Stephen J. Dinsmore Jan 2000

First Record Of A Brambling For Nebraska, Stephen J. Dinsmore

Nebraska Bird Review

On 14 April 1999, an unusual bird was reported visiting the feeders of Phyllis and Dean Drawbaugh in Scottsbluff, Scotts Bluff County, Nebraska. The bird apparently arrived on 13 April immediately after the passage of a cold front with strong northwest winds. On 18 April, the Drawbaughs identified the bird as a female Brambling, and local birders Alice Kenitz and Helen Hughsen confirmed the sighting later that day. On 19 April, I made the trip to Scottsbluff and studied the bird from 7:51-8:55 a.m. in the company of the Drawbaughs, David Ely and Rachel Kolokoff, both of Fort Collins, Colorado. …


A Summer Survey Of The Birds At Two Eastern Nebraska Wetlands, Kristine T. Phipps Jan 2000

A Summer Survey Of The Birds At Two Eastern Nebraska Wetlands, Kristine T. Phipps

Nebraska Bird Review

This study compares the avian species diversity at two eastern Nebraska wetlands that differ in their relative isolation from an urban environment. Birds were surveyed by the point Count method twice weekly at each site during June of 1998. Diversity was measured using species richness and species evenness. The percentage of bird species observed that depend on wetlands for breeding was also compared.

Results suggest that both species richness and evenness, as determined by the Shannon-Wiener index, were higher at the wetland located in a network of other marsh areas and agricultural land than at the suburban wetland. Immigration of …


Gray Flycatcher At Oliver Reservoir, Stephen J. Dinsmore, Loren Padelford, Babs Padelford Jan 2000

Gray Flycatcher At Oliver Reservoir, Stephen J. Dinsmore, Loren Padelford, Babs Padelford

Nebraska Bird Review

On 17 May 1999, we were birding near the main entrance of Oliver Reservoir State Recreation Area in Kimball County, Nebraska. At 8:05 a.m. we found a very gray empidonax flycatcher in the scattered trees south of the main entrance. After studying the bird for a few minutes, we concluded that the bird was a Gray Flycatcher. We studied and photographed the bird at close range until we left at 8:55 a.m.

Review Of The Breeding Status Of Lewis's Woodpecker In Nebraska, Wayne J. Mollhoff Jan 2000

Review Of The Breeding Status Of Lewis's Woodpecker In Nebraska, Wayne J. Mollhoff

Nebraska Bird Review

Lewis's Woodpecker (Melanerpes lewis) was first mentioned as a possible breeder in Nebraska by Bruner (1901), who included it in a list of birds that breed in the state. None of the authorities he cited, however, had published conclusive evidence of breeding, and one of them (Bates 1900) cited only a winter record.

The species was mentioned in reports from the University of Nebraska field parties that worked in the Pine Ridge in 1900 and 1901. Crawford (1901) reports the discovery of only a single empty nest, despite weeks of fieldwork concentrated specifically on gathering nesting data on western species …


Tufted Duck At Lake Ogallala: First Record For Nebraska, Stephen J. Dinsmore Jan 2000

Tufted Duck At Lake Ogallala: First Record For Nebraska, Stephen J. Dinsmore

Nebraska Bird Review

On 2 December 1999, I was birding at the east end of Lake Ogallala in Keith County. I was scanning the large diving duck flock just above the Keystone diversion dam when I noticed a scaup-like duck with a thin crest. I quickly realized that the bird was a male Tufted Duck. I carefully studied the, bird from 9:32-10:28 a.m. The bird spent all of its time actively foraging with a large flock of Greater and Lesser Scaup. It was approximately the same size as a Lesser Scaup. The head shape was rounded like a scaup, not "peaked" like a …


The 1999·2000 Nebraska Christmas Bird Count, Stephen J. Dinsmore Jan 2000

The 1999·2000 Nebraska Christmas Bird Count, Stephen J. Dinsmore

Nebraska Bird Review

The 1999·2000 Christmas Bird Count (CBC) period included ten counts in Nebraska (Table 2). These counts reported a total of 133 species, a great total for so few counts. Counts were scattered statewide, but most effort was in the eastern half of the state where most of the birders are. The top count this year was Lake McConaughy, where the combination of several lingering rarities, excellent participation, and great count weather led to a new record Nebraska count of 101 species, breaking the old record of 87 species. Other excellent totals were 85 at Harlan County, 84 at Branched Oak-Seward, …


Yellow-Billed Loon At Lake Mcconaughy, Stephen J. Dinsmore, Joel G. Jorgensen Jan 2000

Yellow-Billed Loon At Lake Mcconaughy, Stephen J. Dinsmore, Joel G. Jorgensen

Nebraska Bird Review

On 8 August 1998 we observed a Yellow-billed loon (Gavia adamsii) at lake McConaughy in Keith County, Nebraska. We arrived at the pull-off on the south end of the dam at 6:25 p.m. and soon spotted a distant loon off the dam. On the basis of the yellow bill, head pattern, and large size, we concluded the bird was a Yellow-billed loon. We studied the bird until 7:33 p.m. and again from 9:03-9:45 a.m. on 9 August. Compared to a Common loon, this bird was huge and large-headed. The neck was very thick with an almost puffy appearance. …


A Century Of Breeding Birds In Nebraska, Jackie Canterbury, Paul A. Johnsgard Jan 2000

A Century Of Breeding Birds In Nebraska, Jackie Canterbury, Paul A. Johnsgard

Nebraska Bird Review

With the imminent publication of the Nebraska Breeding Bird Atlas and the turning of a new millennium, it is perhaps an appropriate time to survey the state of breeding birds in Nebraska. Wayne Mollhoft's summary of the N.O.U.'s Nebraska Breeding Birds Atlasing Project (Mollhoff, 2000) provides important data bases for the latter part of the past century, and the historic overview by James Ducey (1988) offers a useful basis for judging the breeding avifauna of Nebraska from about the beginning of the century. The Biological Resources Division of the U. S. Geological Survey's (WSGSBRD) annual Breeding Bird Survey data currently …


Spring Field Report, March To May 2000, W. Ross Silcock Jan 2000

Spring Field Report, March To May 2000, W. Ross Silcock

Nebraska Bird Review

This spring was a fairly normal, although I heard comments about warblers being rather tough to find. The reports did confirm that for many of the migrant northwoods species. There were a few rarities, none represented first state records, however. Foremost of these were White Ibis, Glossy Ibis, blue-morph Ross's Goos~, Common Crane, Band-tailed Pigeon, Hammond's Flycatcher, and Black-throated Gray Warbler. The following birds may join these, although each may have fatal flaws, at least in the eyes of the NOURC: Red Phalarope and Slaty-backed Gull. Other interesting sightings included a Mississippi Kite in Lincoln; Gray Partridges in Scotts Bluff …


Mist Netting At Oliver State Recreation Area, Stephen J. Dinsmore Jan 2000

Mist Netting At Oliver State Recreation Area, Stephen J. Dinsmore

Nebraska Bird Review

During the fall 2000 migration, I decided to do some mist netting at Oliver State Recreation Area in Kimball County. My main emphasis was to document the occurrence of several species of Empidonax in western Nebraska. limited netting there in fall 1999 was not very successful, but I was more optimistic this year. With that in mind, I obtained the necessary federal and state permits and netted on four dates (26 August, 31 August, 7 September, and 20 September), each chosen to be immediately after the passage of a cold front.


First Record Of An Arctic Tern For Nebraska, Stephen J. Dinsmore Jan 2000

First Record Of An Arctic Tern For Nebraska, Stephen J. Dinsmore

Nebraska Bird Review

On 20 September 2000, I arrived at Lake Minatare in Scotts Bluff County after the passage of a strong cold front the day before. At 11:36 a.m., I noticed two distant Sterna flying east of the lighthouse. Although the distance was great, I could see that one tern was a juvenile Forster's Tern while the other tern was clearly a different species. Even at a distance, I thought I could see a white cheek, a darker gray belly, and pale upperwings, all indications that the bird was an adult Arctic Tern. I then drove to the lighthouse and soon found …

Fall Field Report, August-November, 2000, W. Ross Silcock Jan 2000

Fall Field Report, August-November, 2000, W. Ross Silcock

Nebraska Bird Review

This fall season was amazing, or as Stephen Dinsmore put it: ''The birding was simply spectacular in western Nebraska this fall," There was something for everyone, whether rarity-chasers, taxonomists, listers, or whatever. There were no fewer than four new species for the state list (pending NOURC approval, of course!), a total of 315 species reported, and fascinating information on western subspecies in the Panhandle.

Numbers of western migrants reached record levels, exemplified by fall totals of 53 Townsend's Warblers, 25 MacGillivray's Warblers, and 28 Western Tanagers. By contrast, eastern migrant warblers in the east were almost non-existent.

At L McConaughy, …


Patterns And Implications Of Aberrant Singing Behaviors Of Black-Capped (Poecile Atricapillus) And Carolina (Poecile Carolinensis) Chickadees In Illinois, Patrick Caesar Enstrom Jan 2000

Patterns And Implications Of Aberrant Singing Behaviors Of Black-Capped (Poecile Atricapillus) And Carolina (Poecile Carolinensis) Chickadees In Illinois, Patrick Caesar Enstrom

Masters Theses

I studied the singing behavior of the closely related Black-capped (Poecile atricapillus) and Carolina (Poecile carolinensis) Chickadees along their range interface in central Illinois. These sibling species are parapatrically distributed from the Appalachians through the Midwest to Kansas. Where their ranges do overlap, small hybrid zones form and chickadees in these areas frequently sing aberrant songs. The majority of the songs studied were recorded 17 April-16 July 1999 in fifteen counties throughout central Illinois. I measured 8 frequency and duration characteristics of the first two notes of songs that began with two whistled notes. The averages of these characteristics …


Effects Of Leafy Spurge (Euphorbia Esula) Infestation On Breeding Birds Of The Sheyenne National Grassland, Nd, Daniel M. Scheiman Jan 2000

Effects Of Leafy Spurge (Euphorbia Esula) Infestation On Breeding Birds Of The Sheyenne National Grassland, Nd, Daniel M. Scheiman

Masters Theses

Leafy spurge (Euphorbia esula) is an exotic invasive weed in the northern Great Plains. We examined the effects of leafy spurge infestation on densities and nest success of breeding birds in grasslands on the Sheyenne National Grassland (SNG), ND. We categorized spurge-infested grasslands into three levels of infestation, based on the area covered by spurge patches: (a) low (0-20%), (b) medium (20-60%) and, (c) high (> 60%). We surveyed 60 100-m radius circular plots (20 in each category), and searched for nests in three 16-ha plots (one in each category). There were no statistically significant differences in mean species richness …


A Century Of Ornithology In Nebraska: A Personal View, Paul A. Johnsgard Jan 2000

A Century Of Ornithology In Nebraska: A Personal View, Paul A. Johnsgard

Papers in Ornithology

The Nebraska Ornithologists’ Union celebrated its centennial year during 1999. During more than 65 years it has published a quarterly journal, the Nebraska Bird Review, and has also published several proceedings of annual meetings as well as special or “occasional” publications. During this same century one native Nebraska bird species (Passenger Pigeon) has become extinct, another (Eskimo Curlew) has possibly become extinct, and at least 15 species apparently have been extirpated as breeding species in the state. Additionally at least seven species have begun breeding successfully in the state, either through purposeful or accidental human efforts, or by range …


Viability Of Piping Plover Charadrius Melodus Metapopulations, Jonathan H. Plissner, Susan M. Haig Jan 2000

Viability Of Piping Plover Charadrius Melodus Metapopulations, Jonathan H. Plissner, Susan M. Haig

United States Geological Survey: Staff Publications

The meta-population viability analysis package, vortex, was used to examine viability and recovery objectives for piping plovers Charadrius melodus, an endangered shorebird that breeds in three distinct regions of North America. Baseline models indicate that while Atlantic Coast populations, under current management practices, are at little risk of near-term extinction, Great Plains and Great Lakes populations require 36% higher mean fecundity for a significant probability of persisting for the next 100 years. Meta-population structure (i.e. the delineation of populations within the meta-population) and inter-population dispersal rates had varying effects on model results; however, spatially-structured meta-populations exhibited lower viability than …

Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials

Executive Summary

This Action Plan covers the pheasants, a group of one African species and 50 Asian ground-dwelling birds, found within Asia from the Caucasus in the west, through the Indian Subcontinent and the Himalayas to eastern China and Japan. They also occur through Southeast Asia to Flores, east of Java. They are largely dependent on forested habitats, making them highly vulnerable to deforestation and habitat degradation. As large, ground-dwelling birds they are also widely hunted for food, plumage, and the live bird trade. Consequently, many species are threatened. The first version of this Action Plan was published to cover …
