The Olive-sided Flycatcher feeds almost exclusively on winged insects, such as bees, wasps, flying, flies, moths, grasshoppers and dragonflies. This bird is often found high in the tree tops on an exposed perch, where it waits and watches for prey to fly by. This bird has seen a population decrease over the last few decades, which may be a result of habitat loss in its wintering grounds in South America.
