FIRST BREEDING RECORD OF THE EARED GREBE IN SONORA, MEXICO
Bibliographic record
Abstract
The Eared Grebe (Podiceps nigricollis) is the most widespread and abundant grebe worldwide, with a distribution that includes Asia, Africa, Europe, and North America. In North America, the species breeds widely through the western and central United States and southern Canada. There is also a small, disjunct, and poorly known breeding population in the highlands of the volcanic belt of central Mexico (Wilson et al. 1988). Away from this population, breeding in Mexico is sporadic, with scattered records from Chihuahua, Nayarit, Jalisco, and Puebla (Dickerman 1969, Williams1982). A former breeding population in Baja California had been presumed extirpated (Huey 1928, Cullen et al. 1999), but recently breeding has been documented annually in Mexicali (Erickson et al. 2011, Mellink and Hinojosa-Huerta 2018). In Sonora, there are infrequent summer records but no previous breeding records (Russell and Monson 1998; eBird.org).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
