Calidris himantopus
Bibliographic record
Abstract
Calidris himantopus (MGT): breeds in northern Alaska east to Victoria Island and west and south to Hudson Bay in Canada. It migrates to South America (northern Chile, Bolivia, Brazil, northern Argentina and Uruguay) in winter and small populations winter in southern USA (van Gils & Wiersma, 1996). Its flyway seems to go from Venezuela straight to the Upper Amazon and Central Brazil, reaching the Atlantic coast in RS (Sick, 1997). Females start migrating from the second week of July on, males start a week after, and juveniles only in mid-August. The return flight is over the coast of Colombia and Venezuela. It reaches the USA in April and the breeding areas in Canada in late May. Males arrive two days before females. Some individuals remain in the wintering areas all year round, but they usually migrate in groups as large as hundreds of individuals (van Gils et al., 2016c). In Brazil, records are centered in the period between September and April and show the presence of this species in Amazonian regions – AM, PA and RO (WikiAves, 2016; MZUSP; MPEG) – in southeastern and southern Brazil – RJ, SP, PR, SC and RS –, in the Pantanal – MT and MS –, and in CE, RN and PE in northeastern Brazil (WikiAves, 2016).

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
