Calidris fuscicollis
Bibliographic record
Abstract
Calidris fuscicollis (MGT): breeds in the Canadian Arctic and migrates to wintering areas in Patagonia. It flies from northeastern North America over the Atlantic Ocean to northern South America and reaches the Guianas in late August,where they remain until mid-September.It moves gradually through the northern coast of South America to areas southeast of the mouth of the Amazon River, when it enters the continent and flies for approximately one month until it reaches Paraguay and RS between mid and late October (Harrington et al., 1991). Some individuals remain during the entire summer in this locality and there are peaks of nearly 7,000 individuals in November and December in Lagoa do Peixe/RS (Belton, 1994), but the main non-breeding area for this species is in southern Argentina and Chile, where it arrives in mid-September, October and November. During its migration to the most meridional regions of South America, it can fly over the Amazon Basin and other humid areas in the country – using the Pantanal as a stopover area (Nunes & Tomas, 2008) – before it reaches Lagoa do Peixe/RS and Tierra del Fuego in Argentina (Barbieri & Paes, 2008). Spring migration starts in late March and early April and seems to be done in long flights. Eventually, it uses Ilha Comprida/ SP as a stopover ground for resting and feeding (Barbieri & Paes, 2008) on its way to North America, where it likely stops to obtain enough fat reserves to accomplish a direct flight to the Canadian Arctic between late May and mid-June, and then breed (Harrington et al., 1991). There are records centered in the period between August and May for almost all states in Brazil that are scarce in June and July and restricted to BA, SC and RS (WikiAves, 2016), probably represented by young non-breeding individuals, since some one-year-old shorebirds mostly stay on wintering grounds through their first summer (Cristol et al., 1999). There is also one museum record for SP in June (MZUSP 2094).

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.
