Animals typically have specialized relationships with plants: ex: chickadees. Become caterpillar specialists when they have offspring but typically eat seeds. This is because caterpillars are soft (easy to feed to baby w/o harm), nutritious (carotenoids, fats, proteins, etc) If the(cid:455) are(cid:374)"t eati(cid:374)g pla(cid:374)ts, they can get them from insects caterpillars have high levels. Need to be in areas where there are a lot of caterpillars. A pair can bring a caterpillar back every 3 min, or more than one at a time.
