Female Cowbird Song Perception: Evidence for Plasticity of Preference
Bibliographic record
Abstract
Abstract The goal of the research reported here was to look for evidence of modifiability of preference for male song in female cowbirds, Molothrus ater. To this end, we investigated whether social experience affected the breadth and consistency of females’ playback preferences for geographic variants of male song. In three experiments, we varied female cowbirds’ exposure to males. Wild‐caught juvenile females showed a preference for local song in their first year when housed without males in sound‐attenuating chambers, as we had found previously with adult females. But we found that neither adult nor juvenile females showed a preference for local over distant song after they had been housed in large, outdoor aviaries with other females but without male residents. Aviary housing with local males did lead to preferences for local songs. These data represent the first unqualified evidence that adult and juvenile female cowbird preferences for song are modifiable. These data add to the growing body of literature suggesting that receivers, as well as signalers, rely on learning during development of their communication system.

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.
