Experiment shows how birds demonstrate self-control over food like humans

Jays can resist temptation to get a delayed but better food reward, demonstrating self-control, according to a study.Researchers from Cambridge University found that the birds which could wait the longest, showing the greatest self-control, also scored highest on intelligence tests.The team designed an experiment inspired by the 1972 Stanford Marshmallow test – in which children were offered a choice between one marshmallow immediately, or two if they waited for a period of time.Source: PA, Cambridge University
