WINDOW STRIKE BIRD MORTALITY ON THEUNIVERSITY OF NEBRASKA – LINCOLN CITY CAMPUS
Bibliographic record
Abstract
On May 25, 1915, in Lincoln, Lancaster County, Nebraska, a Gray-cheeked Thrush was “killed by flying against the library building on city campus” and was found by Robert H. Wolcott and prepared as a scientific study skin by Leroy M. Gates. This thrush is now ZM-6674 in the University of Nebraska State Museum (UNSM) Zoology collections. Birds are typically killed at low level buildings by flying into windows. This thrush is the first documented window strike death for what is now the University of Nebraska – Lincoln city campus. Based upon the UNSM bird collections I report on the last 100+ years (1915 through Dec 2019) of window strike bird mortalities on the city campus (especially 1985-2019). There were a total of 980 specimens of 87 species from 39 separate buildings or building complexes. The University of Nebraska State Museum (UNSM) Division of Zoology collections database was examined for avian specimens salvaged from city campus and whose label data indicated they had died, or very likely died, as a result of striking a window. For the purposes of this project the city campus was defined as being bounded on the east by Antelope Valley Parkway, the south by ‘Q’ Street, the west by 10th Street and what is now Interstate 180, and on the north by what is now Salt Creek Roadway and the approximate location of ‘X’ Street. Only specimens salvaged from university-related buildings within those boundaries were included. The campus has changed markedly over the past 100 years. In 1915 it was only beginning to expand beyond the original four city blocks from 10th to 12th Streets and ‘R’ to ‘T’ Streets. Some specimens had a street address recorded and when that could be determined to be a university building, it was included. Building, or building complexes, are recorded in the Appendix using the current name of the building. If questions arose from the database concerning the specimen, the specimen’s original label was consulted.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
