First Record of the Little Stint for Mexico
Bibliographic record
Abstract
A juvenile Little Stint (Calidris minuta) occurred at Estero Punta Banda, Baja California, Mexico, from 22 to 30 October 2002.The Little Stint breeds in the northern Palearctic and winters primarily in Africa and India.Since 1975 it has been found with increasing regularity as a vagrant in the New World, primarily in Alaska.The observation we report is the first record for Mexico and the first photographically documented record for Middle America.The Little Stiat (Calidris minuta) is one of seven small similarly plumaged arctic-breeding shorebirds known collectively in the United States and Canada as peeps and in Britain as stints.Members of this group pose considerable field identification challenges, the most difficult of which arise among the four small, black-legged species: the Semipalmated (C.pusilla) and Western (C.mauri) Sandpipers and the Little and Red-necked (C.ruffcollis) Stints, all of which are similar in size, structure, and plumage.WORLD RANGE The Little Stint is a long-distance migrant breeding in the high Arctic and wintering primarily in Africa.It has a world population estimated at 1,434,000 (del Hoyo et al. 1996).From June to August it breeds from northern Scandinavia east through north-central Siberia (del Hoyo et al. 1996, American Ornithologists' Union [A.O.U.I 1998), occasionally as far east as the Chukchi Peninsula at Siberia's northeastern tip (Russian literature cited by Gibson and Kessel 1992).It winters throughout Africa and the Mediterranean and east through the Arabian Peninsula and the Persian Gulf to India and Myanmar (del

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
