Spring Field Report, March 2012 To May 2012, W. Ross Silcock

Nebraska Bird Review

This spring was a definite mixed bag ornithologically, in large part due to the mixed bag of weather conditions. Spring Beauty flowers bloomed 10–14 days early at Fontenelle Forest (RBa). Observers were decidedly mixed in their assessments of the season; veteran observers commenting on the passerine migration noted “poorest spring for passerines that I can recall” (LE) and “the sheer numbers of birds seemed ridiculously high for this early date of May 3rd” (JR). It should be noted that the 3 May date saw record counts of a few passerine species at Fontenelle Forest: 65 American Redstarts, 60 Blackpoll Warblers, …

Correction [June 2012]

Nebraska Bird Review

Correction: In the Winter Field Report, December 2011 to February 2012, two Golden Eagles were reported from the Ponca S.P. Christmas Bird Count (March 2012 NBR, page 9). This is incorrect; no Golden Eagles were seen on the Ponca Christmas Bird Count.

Snowy Owl Invasion Of 2011–12, Joel G. Jorgensen, Lauren R. Dinan, Thomas J. Walker Jr.

Nebraska Bird Review

The Snowy Owl (Bubo scandiacus) is an Arctic breeder that regularly migrates to and winters in southern Canada and the northern United States (Parmalee 1992). The number of Snowy Owls moving south and the extent and timing of southward movements in any one year are believed to be dependent on interactions between populations of Snowy Owls and lemmings, the owls’ principal food resource (Parmalee 1992). Infrequently, relatively large numbers of Snowy Owls are observed in areas or regions where few are typically observed, and individuals are observed well south of the normal winter range. These occurrences are often …

Potential For Barn Owl As Rodent Biological Control In Central California Vineyards, Hannah Tillmann

Biological Sciences

The pocket gopher (Thomomys bottae) and voles (Microtus spp.) cause significant economic damage to vineyards. In response, many growers have taken steps to attract Barn Owls (Tyto alba) to their properties to help keep these rodent populations in check. This research project investigated Barn Owl consumption of pocket gophers and voles in Central California vineyards in order to assess the efficiency of this integrated pest management strategy. I collected a total of 715 owl pellets from five vineyard locations in Templeton and Paso Robles, California over an eight-month period during nesting and post-fledging seasons. I …

Nebraska Bird Review

Fifteen counts, one more than last year, were held during the period, and a total of 139 species, 10 fewer than last year, were found. This was a count season of record totals for the state for a number of species. Factors contributing to this include the number of counts, the number of participants and the weather. More counts (15) were run than in any previous year, and several counts (Lake McConaughy in particular) had a much greater than average number of participants. The weather prior to the count period was mild, and most of the circles had unusually warm …

Report Of A Nesting Sora (Porzana Carolina), William M. Lemburg, Wayne J. Mollhoff

Nebraska Bird Review

During the summer of 2008, long-time NOU member and former NOU Treasurer William (Bill) Lemburg of Cairo, Howard Co., Nebraska, discovered the nest of a Sora (Porzana carolina). On 29 July 2008, while using a small flat-bottomed boat to gather duckweed (Spirodela polyrhiza) on a small pond near his bird pens to feed the exotic waterfowl he raises, he noted a pair of Sora walking about, foraging atop the dense growth of duckweed. The pair ignored his presence even though, as he later discovered, he was within 10 feet of their nest. The following evening, 30 …

Winter Field Report, December 2011 To February 2012, W. Ross Silcock

Nebraska Bird Review

The most obvious feature of this winter’s avian movements was the number of Snowy Owls, unprecedented in living memory, that invaded the state. A tally maintained by Joel Jorgensen and Lauren Dinan of Nebraska Game and Parks indicated that over 200 snowies were found in the state, and most were documented. Not as popular with the public, but perhaps of greater scientific interest were the mid-winter reports of species normally rare at this time of year. Most notable in this respect were waterfowl, grebes, cranes, and sparrows. A read-through of these species suggests the very mild winter experienced over most …

Mid-Contract Management Of Conservation Reserve Program Grasslands Provides Benefits For Ring-Necked Pheasant Nest And Brood Survival, Ty W. Matthews, J. Scott Taylor, Larkin A. Powell

School of Natural Resources: Faculty Publications

Conservation Reserve Program (CRP) fields may provide good habitat for nesting and brood-rearing ring-necked pheasants (Phasianus colchicus) during early stages of succession. But, the success of hens in early successional CRP, relative to late successional CRP and other grassland habitats, has yet to be evaluated. The reproductive period is especially critical for populations of pheasants, and CRP’s benefits to hens and chicks may decrease as fields age because of loss of vegetative diversity, decrease in vegetation density, and accumulation of residual litter. During 2005– 2006, we evaluated spatial and temporal variation in nest and brood survival for radio-marked hen pheasants …

First Discovery Of A Four-Egg Clutch For Mountain Plover (Charadrius Montanus) In Nebraska, Bartholomew L. Bly, Travis Wooten

Nebraska Bird Review

On 27 May 2010, the first documented Mountain Plover nest in Nebraska to contain a clutch of four eggs was documented in a fallow strip of a dryland crop field in southern Kimball County. Mountain Plover typically have a clutch size of 3 eggs, though clutches with 1 and 2 eggs are observed in approximately 15% of nesting attempts (Knopf and Wunder 2006). Clutches with 4 eggs are rare and have been reported to occur in less than 1% of the population (Knopf and Wunder 2006). Five 4-egg clutches have been reported in Colorado and one in Montana (see Knopf …

First Documented Nebraska Sighting Of Brown-Headed Nuthatch (Sitta Pusilla), Larry Einemann

Nebraska Bird Review

Monday, November 8, 2010, was an unusually warm (upper 70s) autumn day for Lincoln, Nebraska, with no clouds and a wind from the southwest. I went to Holmes Lake Park in southeast Lincoln to scan for late migrating waterfowl and then to check the stand of conifers for the arrival of winter migrants. Around 11 A.M. I was attracted to a feeding group of six Black-capped Chickadees and three Red-breasted Nuthatches in the 30- to 40-year-old pines and Douglas firs north of Hyde Observatory. I noticed a differently patterned nuthatch in the group. I had seen a Pygmy Nuthatch several …

Fall Field Report, August–November 2011, W. Ross Silcock

Nebraska Bird Review

Overall, this fall migration was routine (waterfowl, warblers, sparrows), but there were a few unexpected highlights. The flooded Missouri River Valley provided habitat that led to some amazing fall counts: 3000 pelicans, 5700 coots, 338 American Golden-Plovers, and 1200 Pectoral Sandpipers. The 10,000 cormorants at Harlan County Reservoir may not have been affected by the Missouri River flooding, and were a record count also. While we're talking numbers, the martin roost in Omaha topped out at 50,000–55,000, and seasonal totals of 4 Red-necked Grebes and 15 Philadelphia Vireos for the state, 34 Mississippi Kites over Ogallala (it's often hard to …

Fall 2011 Bird Banding At Wildcat Hills Nature Center, Colin Woolley

Nebraska Bird Review

Rocky Mountain Bird Observatory has been operating a fall migration bird banding station at the Wildcat Hills Nature Center in Scotts Bluff Co. since 2007. In 2011, during our fifth year of banding, we captured a few new species, had new high totals for other species, and had a record number new high total of recaptures. Weather permitting, we banded on weekdays from August 31 through October 10 for five hours per day beginning soon after sunrise. We caught and banded 735 individual birds of 32 species. We banded two new species for the station in 2011: one Red-eyed Vireo …

Summer Field Report, June–July 2011, W. Ross Silcock

Nebraska Bird Review

The effects of major drought in the southwest United States on bird life in Nebraska has yet to be determined, as has the effect of the historic inundation of the Missouri River bottom lands from Gavins Point Dam to Rulo in eastern Nebraska. The water level at McConaughy is coincidentally at a maximum, ensuring that breeding habitat for Piping Plover and Least Tern was much reduced in the state overall. On the other hand, bottom lands wetlands above the flood level were expanded; Black-necked Stilts initiated a late nesting in Dakota Co in flooded fields that also attracted thousands of …

2011 Bald Eagle (Haliaeetus Leucocephalus) Statewide Nesting Survey, Joel G. Jorgensen, Lisa Yager, Lauren R. Dinan

Nebraska Bird Review

The Bald Eagle (Halioeetus leucocephalus) was extirpated as a breeding species in Nebraska for most of the 20th Century. Nebraska's first active, successful, modern Bald Eagle nest was near Valley, Douglas County, in 1991 (Farrar 1991). Jorgensen et al. (2010) summarized modern Bald Eagle nesting records in Nebraska from 1950 to 2009. Jorgensen et al. (2010) noted the highest annual count of active nests was 54 in 2007. In this note we summarize the 2011 Bald Eagle nesting records in Nebraska.
