Abstract
ABSTR^CT.--Westudied Semipalmated Plovers (Charadrius semipalmatus) during two field seasons in Churchill, Manitoba, to examine the contribution of males and females to parental care during incubation and chick rearing, and to test the hypothesis that birds nesting in habitats with higher visibility and more food (i.e.coastal habitats) tend chicks less closely than birds nesting in habitats with lower visibility and less food (i.e.inland habitats).Males at the coast flew and vocalized more than females during the chick-rearing period, and, in both areas, incubated during the darkest hours (2400 to 0220), whereas females incubated from 0220 to 0530.Incubation shifts were longer at night than during the day but did not differ between sexes or habitats.Incubation by males during the darkest hours may allow females to feed when invertebrates are most active, and may be a mechanism by which females obtain a better energy balance.Coastal habitats contained more food than inland habitats and more potential predators of both chicks and adults.During incubation, parents in coastal habitats exhibited fewer vigilant behaviors than parents in inland habitats, although the overall time budgets for the most common behaviors did not differ between habitats.Parent-chick distances did not differ between coastal and inland habitats, although as chicks became older, they foraged farther from their parents and were brooded less frequently.The apparent response of adults to predators did not differ between the two habitats.The time that parents spent brooding chicks was negatively correlated with ambient temperatures but was not affected by habitat.
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.
