Densidad poblacional del tecolote llanero occidental (athene cunicularia hypugaea) en hermosillo, Sonora, Mexico
Bibliographic record
Abstract
The western burrowing owl (Athene cunicularia hypugaea) is a nocturnal bird of prey distributed in North American grasslands, considered under risk and under special protection in the legislation of Canada and México. However, this species has adapted to urban areas of the municipality of Hermosillo, Sonora, México, and there is a need to understand the status of its population, in order to suggest measures for its conservation. The density of a population residing in the urban zone of Hermosillo, Sonora, was estimated during the seasons of April-May, 2012, and April-July, 2013, times that corresponded to the reproductive season. Thirty sampling units (SU) were selected based on the UTM polygon from the city of Hermosillo; the selection criteria for each of the SU corresponded to: areas with natural vegetation, urbanization, slope, areas without urbanization, agricultural fields without urbanization, and 10% urbanization terrain, which were selected randomly. We estimated a density of 0.43 burrowing owls km21 in average (IC95%(D)0.190.66 individuals km21) in 2012 and 0.33 burrowing owls km21 (IC95 (D)0.120.53 individuals km21) in 2013, with a population size of 105.73 burrowing owls km21 (IC95%(N)48.25163.21) and 81.33 burrowing owls km2-1 (IC95%(N)30.92131.74), respectively, for each sampling season. The densities registered were higher than the ones reported in other studies of the species in urban areas, and they suggest that the urban and peri-urban area of the city of Hermosillo offer a habitat to conserve the population and should be focus of protection for A. cunicularia and its habitat

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.
