Abstract

fetched live from OpenAlex

Columbia.It was nearly sundown, and the place was gathering on the evening shadows, when, within a few feet of where we stood resting for some moments, there suddenly appeared a male hummingbird (A.col•bris) in hot pursuit of a Carolina Wren (Thryothorus l. ludovicianus), the latter leading it a pretty chase through the trees and dense vegetation.Both were giving vent to their peculiar notes indicating their excitement, while' the hummer seemed bent on doing the wren any bodily harm it could effect with its bill.Once or twice it lit close to us, and the scolding notes of the wren brought two other birds of the same species to the scene.These were likewise immediately charged by the valiant little hummer with great vehemence, which uttered as it did so its little, shrill, squeaky pipings.All three of the wrens kept dodging these attacks, and it was remarkable to see the skill with which the hummer shot about after each in turn through the vines and small branches of the trees and shrubs.In a few moments• several warblers put in an appearance, among them a Maryland Yellow-throat (Geothlypis t. trichas), a couple of Parulas (Compsothlypis a. americana), a Magnolia ( Dendroica magnolia), and others which I could not with certainty identify, on account of the increasing darkness.Their arrival seemed to still further excite the hummingbird, which shot first after one, then after another according to their accessibility.In no instance, however, did I actually see it come in contact with the bird attacked, and always on account of the skill of the latter dodging a direct charge; for beyond such linear flights, the hummer could only buzz for a few seconds about the bird he was particularly after in any attack.Neither the wrens nor the warblers made any counter charges, while the entire affair did not last over a minute or two, when both assailant and the assailed flew off in different directions.Never before in my life have I witnessed such a scene; and I can not conceive what could have occasioncd a hummingbird to behave in such a manner.--1•.W. SUUF•LnT, Washington, D.C. Breeding of the Red-winged Blackbird (Agelaius pho•iceus pho•niceus) in Nova Scotia.--OnJune 21, 1914, after repeated searching, I found the nest of the Red-winged Blackbird (Agelaius pho•niceus pho•niceus) in a swamp near Antigonish, Nova Scotia.It was attached to cattail stems and rank grass, and was placed six or eight inches above the surface of water in which I stood knee-deep.It contained four eggs, corresponding exactly in appearance with the description of the eggs of this species given in F. M. Chapman's 'Handbook of Birds of Eastern North America,' 1912 edition.Unfortunately, I did not actually see the female at the nest, but she and a male fluttered over my head, or perched in the nearby bushes while I was examining the nest.They uttered many cries of distress and anger, and I consider that their actions, together with the situation and appearance of the nest and its contents, indubitably determine its identity.I did not collect it, as I did not wish to disturb the birds in any way.A second pair of the same species was present in this swamp and prestonably Vol.

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.
