Crows know. 🪶

A few months ago I reviewed a cool paper about crows' geometric cognition, and I've been eagerly waiting for it to come out ever since.
Fig. 1. Intruder detection task. Two carrion crows were trained to detect an intruder stimulus in an array of six simultaneously presented stimuli. The crows initiated the trial by moving their head in front of the screen whenever a go-stimulus appeared. After a prestimulus period of 200 ms, an array of six stimuli was displayed. The crows responded by pecking on the intruder. In 50% of the trials, the crows were tested with non-quadrilateral background stimuli (top); in this example, the crescent is the intruder among stars. In the other 50% of the trials, the crows were tested with quadrilateral probe stimuli (bottom); in this example, a nonsymmetric quadrilateral is the intruder among symmetric quadrilaterals. Background and probe stimuli appeared pseudo-randomly. All stimuli were individually rotated and scaled in size.
