Black-capped chickadees (Poecile atricapillus) anticipate future outcomes of foraging choices.
Bibliographic record
Abstract
In 2 experiments we investigated the cognitive abilities of wild-caught black-capped chickadees (Poecile atricapillus) in future anticipation tasks. Chickadees were sensitive to anticipatory contrast effects over time horizons of 5, 10, and 30 min (Experiment 1). Chickadees also learned the order of events and anticipated that the quality of future foraging outcomes was contingent on current foraging choices. This behavior was demonstrated while foraging in a naturalistic aviary environment with a 30-min delay between the initial choice and the future outcome (Experiment 2). These results support the hypothesis that black-capped chickadees can cognitively travel in time both retrospectively and prospectively using episodic memory. This result shows the occurrence of anticipatory cognition in a noncorvid species of food-storing bird and supports the idea that cognitive time travel may have evolved in nonhuman animals in response to specific ecological selection pressures.

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.
