Meerkat pups that are successful foragers when young become more efficient foragers as adults, suggesting that they learn and develop foraging skills from early in life. Similarly, young white-winged choughs that depend on food gained by begging lack foraging experience and so are poorer foragers throughout winter (Heinsohn 1991).
