Fall Field Report, August-November 2006, W. Ross Silcock

Nebraska Bird Review

First, I want to say how much I appreciate observers' responses to my requests for additional details on various sightings, not just rarities, but early and late dates. It's important to have these details for the archives to help future readers and researchers feel more comfortable with records from our era.

Patterns that were apparent included a generally quiet fall for waterfowl (they were all at Lake McConaughy), but excellent numbers of the rarer two scoters (but NO White-winged!) and a surprising 16 Red-necked Grebes. On the other hand, numbers of staging Western Grebes were down significantly, apparently due to …

Aerial Searches For Whooping Cranes Along The Platte River, Nebraska, John G. Sidle, Wallace G. Jobman, Craig A. Faanes

Nebraska Bird Review

The endangered Whooping Cranes (Grus americana) that migrate between Wood Buffalo National Park, Alberta and Northwest Territories, and the Aransas National Wildlife Refuge Area, Texas, roost at many aquatic stopover locations (Austin and Richert 2001) including the central Platte River, Nebraska (Johnson 1982; Lingle et al. 1984, 1986, 1991; Faanes et al. 1992; Richert 1999). Under the U.S. Endangered Species Act, 90 km of the central Platte have been designated as critical habitat for the Whooping Crane, although suitable Platte River habitat for Whooping Crane and Sandhill Crane (Grus canadensis) continues to decline (Sidle et al. …

Correction to Winter Bird Numbers Article

Editor's Note: We regret that there was an error in the text of the Paul Johnsgard article "Recent Changes in Winter Bird Numbers at Lincoln, Nebraska" published in the March 2006 Nebraska Bird Review (Volume 74 Number 1). The last sentence in the first full paragraph on page 18 should read: "(The House Sparrow is declining annually at a rate of 2.5%, and the House Finch is increasing at an annual rate of 1.15%.)"

Letter Of Information' Excerpts

Nebraska Bird Review

In the early years of the Nebraska Ornithologists' Union, which was founded in 1899, the organization published its Proceedings, yearly through 1902 and less frequently for the following 13 years. Beginning in 1916, the NOU allied itself with the Wilson Ornithological Club, and its annual proceedings were published by that organization for the next nine years. In 1925, distribution of a mimeographed "Letter of Information" began, with NOU Secretary-Treasurer Myron H. Swenk acting as editor. These Letters, which contain announcements, accounts of meetings and field trips, and notes on bird sightings from members, were published through 1932. They bridged …

Summer Field Report, June-July 2006, W. Ross Silcock

Nebraska Bird Review

Under "Old Business", numbers of Black-capped Chickadees are beginning to recover, but several observers mentioned that American Crows and, most recently, Black-billed Magpies are still suffering lowered numbers. On the plus side, Scissor-tailed Flycatchers continue in increasing numbers, including a pair (or at least one of a pair) that returned to the same location where they nested successfully last year and succeeded again this year.

And now ''New Business". Evidence came to hand that both Western and Clark's Grebes may have suffered poor breeding success due to poor water conditions at traditional breeding sites. An intriguing observation on 28 Jul …

White-Cheeked Geese In Nebraska, W. Ross Silcock

Nebraska Bird Review

The intent of this paper is to summarize the current state of knowledge regarding "White-cheeked Goose" is used in reference to the various taxa included within the two species Canada Goose (Branta canadensis) and Cackling Goose (B. hutchinsii), as constituted by the American Ornithologist' Union (AOU; 2004). Using culmen measurements, confirmation of both species' and the "expected" subspecies' occurrence in Nebraska was documents, but culmen measurements alone could not confirm the occurrence of any of the "unexpected" subspecies.

TAXONOMY

As many as 10 subspecies of White-cheeked Goose were described by the AOU (1957), five of which ( …

2005 (17th) Report Of The Nou Records Committee, Mark A. Brogie

Nebraska Bird Review

The functions and methods of the Nebraska Ornithologists' Union (NOU) Records Committee are described in its bylaws (NOU Records Committee 1986). The committee's purpose is to provide a procedure for documenting unusual bird sightings and to establish a list of all documented birds for Nebraska. "The Official List of the Birds of Nebraska" was first published in 1988 (NOU Records Committee 1988) and has been updated two times (NOU Records Committee 1997, 2004).

The "Official List" has been appended fifteen times: (Mollhoff 1989; Grenon 1990, 1991; Gubanyi 1996a, 1996b, 1996c; Brogie 1997, 1998, 1999, 2003, 2004, 2005; Jorgensen 2001, 2002, …

Nou 2006 107th Annual Meeting At Ponca State Park

Nebraska Bird Review

The 107th Annual Meeting of the NOD was held in the new Missouri River Resource and Education Center in Ponca State Park on May 19-21. Although the weather ranged from hot and windy on Friday to steady rain on Saturday morning to cool and breezy on Sunday, the 80+ attendees accumulated a list of 159 species. Warbler diversity was disappointing, but shorebirds were abundant.

On Friday evening, a program on the Galapagos Islands was presented by Dr. Paul Johnsgard, Linda Brown, Dr. Josef Kren and Allison Johnson. Each of the four recounted an aspect of their 2005 trip to the …

A Book-Collector's Guide To Roger Tory Peterson, Paul A. Johnsgard

Nebraska Bird Review

One of the major disappointments of my youth was that I grew up without access to a real field guide to birds. My early years were spent in a small North Dakota village that lacked a library, and my only reference book on birds was a badly-tattered copy of a badly-illustrated 1912 book that my mother had grown up with, Chester A. Reed's Birds of Eastern North America. However, in 1939 a very kind aunt gave me a still-cherished copy of the Macmillan edition of Audubon's Birds of America as a Christmas present. With its hundreds of wonderful color …

Spring Field Report, March-May 2006, W. Ross Silcock

Nebraska Bird Review

Introduction

As many of you know, the American Ornithologists' Union (AOU) has changed some generic names and rearranged the taxonomic order for shortbirds in the expanded genus Tringa and for the terns. This Spring Report uses the new taxonomic order.

Observers (thank you, I think!) submitted a huge amount of data that I distilled for this report; I entered more than 3,500 sightings into my database, which allows for a comprehensive overview of what birds were doing this spring.

As has been the case the last few years, there were several record or near-record early arrival dates, some requiring documentation …

2005-06 Christmas Bird Counts In Nebraska

Nebraska Bird Review

For the first time this year, two additional counts, Ames and Harrison Sioux Counties, were reported, bringing our total to 14 counts. The all-time high numbers reached for several species this year need to be regarded in light of that fact. We tend now to have more counts, more counters, and more hours spent counting than ever before. While this is a good thing, it is useful to remember that counting more birds does not in this case mean that there are necessarily more birds present. A look at the effort data, such as number of birds per party hour, …

Corrections to 2004-05 Christmas Bird Counts

Recent Changes In Winter Bird Numbers At Lincoln, Nebraska, Paul A. Johnsgard

Nebraska Bird Review

In 1998 I summarized historic Christmas Bird Count data for Lincoln and Scottsbluff (Johnsgard, 1998), since these two sites provide the longest continuous count records for any Nebraska locations. Eight more years of data have since accumulated, during which there has been an increasing awareness of the perceived effects of global warming (Inkley, 2004) on bird populations. The purpose of this paper is to compare the data for the past eight years (1998-2005) with earlier counts for Lincoln, two of which were first performed in the early 1900's, but which have been conducted in unbroken sequence since 1947. These data, …

Treasurer's Report December 31, 2005

Winter Field Report, December 2005 To February 2006, W. Ross Silcock

Nebraska Bird Review

The traditional mid-summer and midwinter "windows" wherein migrants were rarely detected have closed markedly in the last few years. The midwinter window is closing; where it once was around 20 Dec-20 Feb it is now more like 5 Jan-to Feb. Many waterfowl were found in midwinter this season, and migrants such as Bluewinged Teal and Sandhill Crane appeared very early this spring. Similarly early were Turkey Vulture and Lincoln's Sparrow. In light of waterbirds lingering late in fall, markedly lower numbers of Western Grebes were a surprise.

Exotics were widely-reported; one, Pink-footed Goose, could possibly be a vagrant wild bird, …

Fall Field Report, August–November 2005, W. Ross Silcock

Nebraska Bird Review

This fall was notable for its lack of notable events; numbers of migrants reported in all species groups, especially waterfowl, shorebirds, and warblers, were low. Lingering birds were both insectivores and seed-eaters, and, coupled with a rather stable fall weather-wise, it seems that there were no disturbances to concentrate birds or otherwise impede a steady flow of migrants through the state. Without concentrations, migrants are often not noticed or, more accurately here, not reported by observers.

The best Western Grebe count was 2500, very low relative to expected high fall counts of at least 20,000. Mergansers were the only bright …

Fall Field Days At Harlan County Reservoir

Nebraska Bird Review

The annual Fall Field Days were held on September 9–11, 2005, at the 4-H Camp near Alma. Field trip destinations included Harlan County Reservoir and various other points of interest in Furnas, Harlan, Franklin, Phelps, Kearney, and Adams Counties. The total tally was 119 species, including Snowy Egret, Yellow-crowned Night-Heron, Mississippi Kite, Prairie Falcon, and Olive-sided Flycatcher.

Fifty-four members and guests attended. On Friday the group heard from Dr. Josef Kren on the topic of obligate brood parasites, species that have lost the ability to construct nests and incubate eggs and instead lay eggs in the nests of other species, …

Suggested Areas For Study, William F. Rapp Jr.

Nebraska Bird Review

After 100 years of organized ornithology we have a good picture of the bird fauna of Nebraska. Yes, we will still be able to add new species to the state list, but this will become more and more difficult. What problems are left for the amateur ornithologist to solve? Nebraska is a big state with many different ecological areas, few of which have been studied in detail. Only a few areas of the state have been well studied. Not only do we need data on what species occur, but how many. This type of study can be done by amateur …

Snowy Plover Nesting At Lake Mcconaughy In 2004 And 2005, Mark M. Peyton, Gabriel Wilson

Nebraska Bird Review

The Snowy Plover (Charadrius alexandrinus) is a small shore bird that upon casual observation resembles the Piping Plover (Charadrius melodus). The most obvious differences are in the dark beak and legs of the Snowy Plover in contrast to the orange bill with the black tip and orange legs of the Piping Plover. The two also have strikingly different calls (pers. obs.). In Nebraska the Piping Plover can be found along the Missouri, Platte, Niobrara, Loup, and Elkhorn Rivers and the sandpits associated with those rivers (Haig and Plissner 1993). Piping Plovers are also common along the …

Multiple Black-Necked Stilt Nesting Records In The Rainwater Basin, Joel G. Jorgensen, Paul Dunbar

Nebraska Bird Review

Black-necked Stilts (Himantopus mexicanus) have increased throughout much of the mid-continent in recent decades (Will 1999, Brinkley 2003, Brinkley and Baicich 2004). Prior to 1970 there were fewer than ten Nebraska records (Sharpe et al. 2001 ). Reports have increased since 1970 and are now annual. Breeding was first recorded in Nebraska in 1985 at Crescent Lake National Wildlife Refuge (Heisinger 1985). Breeding has been more or less regular in the western Sandhills since then (Sharpe et al. 2001) and additional breeding records have occurred in Scotts Bluff (Silcock 2002b ), Keith, and Hall Counties (Silcock 2000b ). …
