Calidris pusilla
Bibliographic record
Abstract
Calidris pusilla (MGT): breeds in northern Canada and Alaska, and overwinters mainly in South America (Gratto-Trevor & Dickson, 1994). It flies non-stop for as long as 4,000 km and is known to form flocks of 350,000 individuals.The species presents high fidelity to its breeding sites, but little is known about its wintering areas. Around 2/3 of the juveniles remain in non-breeding areas throughout the year (van Gils & Wiersma, 1996). Long-distance migration between the wintering area in the Southern Hemisphere and the breeding area in high latitudes from the Northern Hemisphere are interspersed with long stopover periods for energy storing, especially in Delaware Bay on the east coast of the USA, where it usually begins to arrive in early May and remains until early June (Mizrahi et al., 2012). In the Amazonian region, there are records throughout the year for PA and AP (Stotz et al., 1992; Campos et al., 2008; WikiAves, 2016) with a population peak in AP in November and December (Campos et al., 2008). There are recent records in all coastal states (WikiAves, 2016). It is recorded all year round in PE, CE and MA and there are population peaks on Caranguejo Island/MA during the fall migration from September to November due to the arrival in northern Brazil of migrants originating from stopover sites in northern South America (Carvalho & Rodrigues, 2011; WikiAves, 2016). The species can be observed in other states in northeastern Brazil (PI, CE,RN,PB,PE, AL, SE and BA) from August to April (Azevedo-Júnior et al., 2001; Cardoso & Nascimento, 2007; Cardoso & Zappelini, 2011; WikiAves, 2016; MZUSP; MPEG; MNRJ). There are population peaks between November and February in SE (Almeida & Ferrari, 2010) and in March in the Piaçabuçu Environmental Protection Area/AL (Cabral et al., 2006). It is also recorded from August to April for the states in the southeastern and southern regions (WikiAves, 2016; MZUSP).

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.
