Predicting Nesting Habitat Of Northern Goshawks In Mixed Aspen-Lodgepole Pine Forests In A High-Elevation Shrub-Steppe Dominated Landscape., Robert A. Miller, Jay D. Carlisle, Marc J. Bechard, Dena Santini

Robert Miller

We developed a habitat suitability model for predicting nest locations of breeding Northern Goshawks (Accipiter gentilis) in the high-elevation mixed forest and shrub-steppe habitat of south-central Idaho, USA. We used elevation, slope, aspect, ruggedness, distance-to-water, canopy cover, and individual bands of Landsat imagery as predictors for known nest locations with logistic regression. We found goshawks prefer to nest in gently-sloping, east-facing, non-rugged areas of dense aspen and lodgepole pine forests with low reflectance in green (0.53 - 0.61 μm) wavelengths during the breeding season. We used the model results to classify our 43,169 hectare study area into nesting suitability categories: …

The Art And Artistic Legacy Of Louis Agassiz Fuertes, Paul A. Johnsgard

Paul Johnsgard

Perhaps some Nebraska birders will not immediately recognize the name Louis Agassiz Fuertes, as he died almost 80 years ago. Yet he influenced the art of bird painting as much as did John James Audubon, and provided wonderful artwork for many major state bird reference books. He also personally tutored George Miksch Sutton, the Nebraska-born artist and biologist who provided the NOU with its Burrowing Owl logo, and who contributed greatly to American ornithology, especially that of the southern Great Plains. It is interesting that, like John James Audubon, Roger Tory Peterson, and George Miksch Sutton, we would never think …

Review Of 'My Way To Ornithology' By Olin Pettingill, Jr., Paul A, Johnsgard

Paul Johnsgard

Most Nebraskans who recognize this author's name probably will remember him as a cinematographer and lecturer in the Audubon Screen Tour series. The series was a regular part of live entertainment in Lincoln and Omaha until the early 1960s. Other bird-oriented people will know that Pettingill wrote two of the first and still best regional bird-finding books (detailed guidebooks to bird-finding localities in the states east and west of the Mississippi, respectively). Perhaps still others will remember him as a one-time teacher of ornithology at Carleton College and the University of Michigan Biological Station, or as a director of the …

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

Paul Johnsgard

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 …

Louis A. Fuertes And The Zoological Art Of The 1926–1927 Abyssinian Expedition Of The Field Museum Of Natural History, Paul A. Johnsgard

Paul Johnsgard

The year 2009 marked the 110th anniversary of the first colored reproduction of a Fuertes painting; a watercolor of two seaside sparrows published in The Auk, when Fuertes was about 25 years old. Although Fuertes' life spanned little more than a half-century, and most living ornithologists were born after his tragic 1927 death, his influence on natural history art has not lessened. This manuscript is a testimony to his enduring artistic legacy. I first looked in awe at the original set of Fuertes paintings in the summer of 1995, during a visit to the Field Museum in conjunction with my …
