Abstract

fetched live from OpenAlex

T HE incubation patch of birds consists of one or more areas of the skin of the breast and belly that become denuded of feathers and highly vascularized prior to incubation. Its function is to permit intimate contact of the body of the bird with the eggs, thereby increasing the efficiency of heat transfer. In its formation down feathers alone or both down and contour feathers may be lost. In passerine birds this feather loss is caused by a localized molt that results from hormonal action. (Bailey 1952). Whereas it is common knowledge that the incubation patch in water-fowl is formed when the female plucks breast fathers for the nest, little attention appears to have been given to the details of its formation and subsequent history. The present observations on the incubation patch of wild geese, which were made at Perry River, District of Mackenzie, N.W.T., Akimiski Island, N.W.T. (in James Bay), in the Sutton River area, Ontario

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
