Abstract
We investigated susceptibility of Song Sparrow (Melospiza melodia) nests to discovery by nest-searching Brown-headed Cowbirds (Molothrus ater) at Delta Marsh, Manitoba. We assessed the importance of nest habitat and microhabitat as well as host activity in influencing the likelihood of parasitism by measuring vegetation and behaviour of hosts at nests that were (1) not parasitized, (2) parasitized once and (3) parasitized more than once, by the same female or by more than one female (i.e. multiple parasitism). None of the variables measured was significantly related to parasitism, but non-significant trends consistent in both years of the study suggested that concealment and host conspicuousness play important roles, but quantifying them is difficult and complex. A significant relationship between nest mass and the probability of parasitism further supports this suggestion, because nest mass should reflect nest-building activity as a whole.

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
