Abstract

fetched live from OpenAlex

IN the course of a critical revision of the Song Sparrows of eastern North America, undertaken in connection with my studies of the birds of Labrador and Hudson Bay, and which will appear in my forthcoming report on the ornithology of this region, an apparently new race from the coast of Virginia has been found.This I propose to call Melospiza melodia atlantica, subsp.nov.Type, No. 294,442, Collection U.S. l•ational Museum, adult male; Smith's Island, Virginia, May 25, 1898; William Palmer.Subspecific characters.--Similar to Melospiza melodia melodia of the Atlantic slope region, but much grayer above, with the blackish streaking more distinct, and the reddish brown feather-edging reduced to a minimum.More nearly resembling Melospiza melodia juddi, but more grayish above even than that form.Measurements of type: wing, 67 mm.; tail, 65; exposed culmen, 12; tarsus, 21.Remarks.--Thenew race is represented by a series of twenty-one breeding birds (May and June) from Smith's Island and Cobb's Island, Virginia, collected by Messrs.Joseph H. Riley, Edward J. Brown, the late William Palmer, and Dr. Louis B. B!shop.In series it is strikingly different from melodia, but is to be separated from juddi only by being still more grayish than the average indivldual of that form.This grayish cast is a pronounced feature even in fall and winter specimens, as shown by a December bird from Virginia Beach (on the mainland), and by three specimens from Pea Island and vicinity, on the coast of North Carolina.While it is evidently a littoral race, the series at my command will not admit of working out its range with precision.No specimens from New Jersey have been examined, but two May specimens from Pocantico, New York, and one from Shelter Island, at the eastern end of Long Island, approach arianfica very closely, and suggest that it may eventually be found to inhabit the entire coast region from Long Island to North Carolina.' •rol.XLI]

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.
