Echolocation and foraging ecology of the bristle-faced free-tailed bat, Setirostris eleryi, in central Australia
Bibliographic record
Abstract
We document the spectral characteristics of echolocation sequences of Setirostris eleryi recorded from riparian zones in the Central Ranges in Western Australia, near Warakurna. These are the first records of this species in Western Australia. The sequences are comparable to reference S. eleryi sequences from near Alice Springs, as well as to sequences from a nearby vouchered specimen locality (Hull River in the Northern Territory), yet distinct from Scotorepens greyii sequences from Western Australia, including locations in the Central Ranges. The central Australian S. eleryi sequences average 3 kHz higher in frequency than reference S. eleryi recordings from eastern Australia. We deduce the species’ foraging strategy, microhabitat, wing beat frequency and flight speed from the echolocation sequences, then show that these deductions are consistent with calculations based on an airframe analysis of museum specimens, and with available field observations. The echolocation recordings provided a quick, passive, cost-effective characterisation of foraging niche, useful for conservation planning.
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.
