Abstract
None:
A recent study trained three tool-naïve carrion crows (Corvus corone) to use a stick tool for getting a reward out of a crevice. Automated tracking of tool tips showed gradual changes of their trajectories, demonstrating improved efficiency in their tool dexterity over time (Moll et al. Current Biology, 35, 4845-4852, 2025).

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.
