Abstract

fetched live from OpenAlex

had evidently just arrived fronl some favored point in the South, their phnnage being particularly fresh and bright, and such rare species as the Mourning and Connecticut Warblers and the Green Blackcap being conspicuous.Presently I noticed one on a willow overhanging the water, which seemed to be a compromise between the Sumlner Yellow Bird and the Yellow-throated Vireo.On picking it up I was greatly pleased to find [ had got a specimen of tbe Protbonotary Warbler--a fernale in the ordinary plumage of tbe season.It is the first record of the species for Ontario aud the second for Canada, the first being that of a specimen which was found at St. Stephens, New Brunswick, by Mr. Boardsnan in October, •862.--K.C. MclLwRAITH, lIamœ1lon, Ontario.Bachman's Warbler (Ilelminlho•3hila bac4manl) in Louisiana.--DuringMarch, I888, I collected thirty-one Bachman's Warblers on the borders of Lake Pontchartrain, Louisiana.They were probably more abundant than in •887, as about the same effort was made last year to secure them, by at least a dozen hunters, commencing earlier and continning later in the season, with the result of but six specimens.It is somewhat remarkable that of the six secured in the spring of 1887 four were females while among the thirty-one killed this year there were not any females.This bird, so long unsuccessfitlly sought for, is evidently a stranger to the forests of Louisiana except during the migration, for those taken this season were killed between the 2d and 2oth of March, and although they were diligently sought for up to the •niddle of April no specimens were obtained later than the end of Marcb, showing pretty clearly that tbe breeding place is farther north.No sound •vas heard frown tbem except in the case of two of the finest, wbicb were so low dowu on the tree on which they were discovered, tbat their planlage was easily distluguisbed; my assistant reported that the shooting of the first failed to disturb the second one, which remained on the tree and uttered a cbirping note as if calling to its dead companion.Nearly, or quite all the other specimens obtained were found in the conlpany of a variety of other early Warblers in the tops of the sweet-gum, probably attracted by insects found in tbe buds and blossoms of this tree. Of the Swainson's Warblers (t]el[na[a swainsoni),l secured but three specimens this year, against nine in I857, and abont forty in the spring of 1886.Although tbese birds do not arrive in Louisiana until about the middle of Marcb, it is quite probable tbat many of them remain and breed in this latitude.--C.S. GX•U•X•TI•, Igesl l/oboken, 2V.Helminthophila celata in Connecticut.--May8, 1888, I shot a •nate bird of this species.It was in company with Nashville Warblers when killed.As far as I can ascertain this is the only speci•nen actually taken in Connecticut, although it has heen observed close by the Connecticut line in New York.--WILLARI)E. TREAT, ]•as! t[arlford, Conn.Dendroica c•erulea in the District of Columbia.--OnMay 5, 1888, I had the pleasure of adding Dendroœca wrulcea to the fauna of the Dsltrict of1SSS.]General Notes.

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.
