Charadrius semipalmatus
Bibliographic record
Abstract
Charadrius semipalmatus (MGT): departs from breeding sites in Canada between July and September (adults fly before juveniles) and overwinters on the coast and on all major islands from North, Central and South America. It reaches South America between September and early November and returns from April forward. In boreal spring, Delaware Bay, USA is an important stopover area, where around 70% of the population meets to prey on larvae of the horseshoe crab Limulus polyphemus (Wiersma,1996). As part of its pathway,it flies across Brazil from São Luís and the mouth of the Parnaíba River to the Baía de Todos os Santos (Antas, 1983), reaching the coast of SP in late August and early September, where it remains during spring and the beginning of summer. The number of individuals begins to decrease in mid-April when adults return to the Northern Hemisphere for breeding and only juveniles remain. It is suggested that the municipality of Ilha Comprida/SP is one of the stopover areas for foraging and resting during the return migration to the Northern Hemisphere (April) and to foraging areas in the Southern Hemisphere (September) (Barbieri et al., 2000). The species appears to be present in Lagoa do Peixe/RS throughout the year, reaching as many as 300 individuals in March (Belton, 1984). There are records for the Amazon Basin in Macapá/AP, Manaus/AM and PA between September and December (Stotz et al., 1992; Campos et al., 2008; Cintra et al., 2011; Silva, 2011b; Valente, 2011).

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.
