These birds were put to the test in a study led by scientists from Anglia Ruskin University and the University of Cambridge. Challenge: Choosing quickly between a low-quality snack and a gourmet treat is a true test of the bird’s self-control.
Here’s what they found: Both jays and crows preferred delayed, high-quality rewards when they were alone. But when other birds came on the scene, the jays quickly retreated, making a quick decision to avoid potential competition, and the crows remained unconvinced and always strived for good.
Chief investigator Dr. Rachel Miller suggests that these food fiascos may provide clues about each species’ level of social tolerance and survival tactics.
