Caterpillar disguised as feather to escape hungry birds

This Caterpillar filmed near Mindo in Ecuador looks like a feather which presumably gives it an advantage in the struggle for survival since predators such as birds will not perceive it as food. There are more than 3500 species of butterflies and some 10000 of moths in Ecuador and their larvae have evolved different strategies to escape predators. Some hide in the vegatation due to camouflage coloration, others resemble a stick or moss or mimick bird droppings. Bagworms build cases out of silk and materials
