Abstract
161-169.--Analysis of movie film of flocks of several species of geese and the Merganser reveals that members of the flock do not show a phase relationship of wingbeats, and the angle of formations and the distance between birds vary.The author argues that these observations effectively abolish the bases for the hypotheses holding that birds in linear flocks derive an aerodynamic advantage.The author proposes that linear flocks provide best optical contact and least risk of collision.This reviewer feels that further observation and refinement of hypotheses are necessary, but this appears to be another case where the theoreticians might deign to do a little bird-watching.(English summary.)--H.C.M.

WALXER.1972.Sleep in the Burrowing Owl (Speotyto cunicularia hypugaea).Behav.Biol.?: 183-194.--Electrodesfor recording cortical electroencephalograms (EEG) and eye and neck muscle electromyograms (EMG) were implanted in four adult Burrowing Owls.Describes three distinct states of sleep and wakefulness after acclimation.Reports patterns of sleep and wakefulness periods.Discusses the findings with reference to the evolution of rapid eye movement (REM) in animals.The owls, whose eyes are immobile, lacked EMG hypotonia of the neck and phasic eye muscle activity described in other birds during desynchronized sleep.The authors believe these differences support the hypothesis that the evolution of REM sleep might be linked with the evolution of binocularly coordinated eye movement.--W.D.C.FAB•ICIVS, E.• ANY L. F•,LT.1969.[Sexual imprinting in Mallard hens.]Zool.Revy 31: 83-88.--Experimentsby Schutz (1963-68, published in various journals) have led to the assumption that sexual imprinting does not occur in Mallard hens.An incubator-hatched hen showed normal sexual behavior toward men.Experiments with hen ducklings reared in association with white drakes, and subsequent sexual attraction of some of these hens to white (abnormal) drakes, show that sexual behavior in Mallard hens can be elicited by objects (man, white drake) not having the nuptial coloration of the drake, provided the hens have been massively exposed to such an object during the period when normal drakes of their own age develop their nuptial plumage.(In Swedish with English summary.)--M.D.F.U.F•v•icKso•, L.

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.
