NOTES: ADDITIONAL NOTES ON THE SOUTHERN LIMIT OF THE ANCIENT MURRELET IN BAJA CALIFORNIA, MEXICO
Bibliographic record
Abstract
The Ancient Murrelet (Synthliboramphus antiquus) has been recorded six times in Mexican waters, five times off the northwest coast and once off the southeast coast of the Baja California peninsula. The first record, and the only specimen, was of a bird taken near Ensenada on 25 December 1927 (Grinnell 1928). The second record was of a group of five seen near Islas Los Coronados on 24 February 1980 (McCaskie 1980, Erickson et al. 1995, Howell and Webb 1995), not 1975 as given by Wilbur (1987). An apparently unhealthy bird in first-year basic plumage was photographed at close range in Ensenada harbor on 9 January 1994 (Erickson et al. 1995). The following year, a group of three was observed west of Punta Arena near the southeast tip of Baja California Sur on 21 December 1995. These birds had “black bibs with white [plumage] behind” (Erickson and Howell 2001:126), suggesting individuals in their second year or older. This record is the most southerly of the Ancient Murrelet on the eastern coast of the Pacific Ocean. Nearly three weeks later, on 8 January 1996, one Ancient Murrelet was seen just north of Ensenada at El Sauzal harbor. Last, an individual was observed at Ensenada on 3 January 1998 (Erickson and Howell 2001).

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.
