Comparative Study of the Nesting Behavior of Chestnut-sided and Nashville Warblers
Bibliographic record
Abstract
TI•E study of the Chestnut-sided Warbler (Dendroica pensylvanica) was made during May, June and July, 1945, and that of the Nashville Warbler (Vermivora ruficapilla), during June, 1946.Both nests were in my study area on the west side of Pimisi Bay, just south of the Mattawa River which flows into the Ottawa River at the town of Mattawa fifteen miles farther east.The place is situated in the township of Calvin, District of Nipissing, Ontario.For invaluable encouragement as well as assistance with the correction of this manuscript and helpful suggestions about charts and diagrams, I am particularly indebted to Dr. J. Murray Speirs and Doris Huestis Speirs.Further, I wish to acknowledge the kindness of Mr. James Baillie, Jr., who arranged for me the loan of certain literature from the library of the Royal Ontario Museum of Zoology, and of Mrs. Hugh M. Halliday, who found the nest of the Nashville Warbler and allowed me the free use of her notes.The instruments used in both studies were an ordinary clock with large dial and a pair of 8 x 30 Zeiss marine binoculars.THE NESTS The Chestnut-sided Warbler's nest was discovered in the forenoon of May 27, 1945.The female was just engaged in fastening the bottom to converging stalks of a raspberry bush, about 18 inches from the ground.Two hours later the nest was half finished and the female was sitting in it moulding it into shape with breast and body.Still later a white string was observed lying across the nest and this was eventually woven into the structure.The male was not seen during the building.However, continuous observation was not possible at the time, but Kendeigh (1945) spoke of the males as being "somewhat attentive to the females during the nest-building . .."After a day of rainy and cold weather (temp.54-62 degrees Fahrenheit), during which little or no work was done on the nest, it was finally completed on May 29.During the next four and a half days the nest was seemingly abandoned until, at 4:50 a.m. on June 4, the first egg was laid.The location of the nest was at the northeastern edge of a fairly open space in the woods, overgrown by what later would become a thick covering of tall bracken.In the middle of this space stood a lone poplar tree.For the rest, the area harbored little else than a few sapling white birches and aspen trees, and a couple of red maples and 204 LAWRENCE, Chestnut-sided and Nashville Warblers[ Auk

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.
