{"fact":"Crows exhibit a fascinating behavior: they blink less often when fixated on a threatening face, possibly indicating heightened focus and attention to potential danger.","context":"In nature, crows blinked less when they looked at threatening people than when they fed in conspecific flocks (Fig. 5B). During our experiments, crows froze, stared at the person, and flashed their conspicuous white nicti-tating membrane on average 29 times per min (SE = 4.4) upon seeing the threatening face.","source":"John M.
