Abstract
Amplitude, or intensity, of sound is a fundamental characteristic of acoustic communication, with relevance in many scientific fields. The amplitude of an animal's acoustic signal at its source (‘source amplitude’) may be particularly relevant in the field of acoustic allometry, where relationships between species' physical and acoustic features (e.g. dominant frequency) have been well‐established across taxa. However, despite their potential scientific value, records and studies of source amplitude remain remarkably scarce for avian species. Here we present novel estimates of source amplitude (range and median) for 17 species of Arctic‐breeding birds, derived from measurements made in Utqiaġvik, Alaska, during June 2024. We found a strong positive correlation between body‐mass and source amplitude in these data via Markov chain Monte Carlo multivariate generalized linear mixed models (MCMCglmms). This relationship was influenced by both phylogenetic and individual identity. In contrast, effects from environmental factors and measurement characteristics were minimal. Our work represents one of few studies that explicitly model an interspecific relationship between source amplitude and body mass across avian genera. We hope that this study will spur further investigations into avian source amplitude and its relationship to morphological and life‐history features for species in the Arctic and elsewhere.

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 it
