236. Western Harvest Mouse Reithrodontomys megalotis French: Souris-moissonneuse de |'Ouest / German: Westliche Erntemaus / Spanish: Raton espiguero occidental Other common names: Southern Marsh Harvest Mouse Taxonomy. Reithrodon megalotis Baird, 1858, “between Janos, Sonora [Mexico] and San Luis Springs [New Mexico, USA].” Reithrodontomys megalotis is in subgenus Reithrodontomys. Fifteen subspecies recognized.

Head-body 63-74 mm, tail 55-96 mm, ear 10-16 mm, hindfoot 14-20 mm; weight 8-13 g. The Western Harvest Mouse is small. Dorsum is light brown or grayish to blackish at base, with buffy tips. Venter is dark buff to white, often with buffy pectoral spot. Tail is bicolored and equal to head-body length. Habitat. Widespread in various habitats ranging from pine-oak forests to natural grasslands at elevations 76 m below sea level in Death Valley, California (USA) to 4000 m. In forested areas, Western Harvest Mice are typically found in areas covered with grass, weeds, and shrubs. Food and Feeding. The Western Harvest Mouse is mainly granivorous but occasionally eats plant material and invertebrates. Breeding. Males tend to be polygamous. Offspring are born in spherical nests ¢.12 cm in diameter, constructed with grass and other vegetation. Gestation is c.5 days. Litters have 1-9 young. Young are altricial birth and are weaned after c.25 days. Activity patterns. The Western Harvest Mouse is nocturnal and mainly terrestrial. Movements, Home range and Social organization. Home ranges are large at ¢.3500 m?. Generally, densities are 4-11 ind/ha but in exceptionally good years can increase to 60 ind/ha. In central Mexico, densities of 0-7-15-8 ind/ha have been reported in open areas and fields. Status and Conservation. Classified as Least Concern on The IUCN Red List. Bibliography.

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.
