BLACK SKIMMER OCCURRENCES IN NEW MEXICO, INCLUDING A HIGH ELEVATION RECORD
Bibliographic record
Abstract
On the morning of 12 May 2007, W. H. Howe and M. D. Howe discovered an adult Black Skimmer (Rynchops niger) resting in the company of other waterbirds on the shore of Heron Lake, Rio Arriba County, New Mexico, and obtained photographs and videotape to document the record (Figure 1). During 35 minutes of observation (15:10–15:45), the skimmer remained on the shore with the other birds; two hours later, upon their return to the site, the Howes noted a vehicle parked close to where the birds had been and all birds were gone. The skimmer was not seen again despite searches the next morning by D. J. Krueper and J. M. Ruth. Heron Lake, at 2192 m, is situated in the San Juan Mountains of north-central New Mexico and is only some 50 km east of the continental divide; it is in the Chama River valley, a part of the Rio Grande drainage. The Heron Lake skimmer appears to represent an altitude record for the species in the United States and Canada, eclipsing another adult at 2092 m in Colorado’s San Juan Mountains at Pastorius Lake near Durango, La Plata County, 29 April 2004 (N. Am. Birds 58:406). For North America generally, these are approached or matched only by records from the interior highlands of Mexico, including ones to 2000 m in the state of Durango and about 2200 m in the Valley of Mexico (Williams 1982). For the species as a whole, however, no North American record tops those from South America, at 3900 m on the Bolivian altiplano (Fjeldsà and Krabbe 1990).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
