Editing American redstart (section)

===Feeding===
The redstarts feed almost exclusively on [[insect]]s which are usually caught by flycatching. American redstarts also have been known to catch their insect prey by [[Gleaning (birds)|gleaning]] it from leaves. This is a very active species. The tail is often held partly fanned out. These birds have been observed flashing the orange and yellow of their tails on and off to startle and chase insects from the underbrush. Overall, this species is a very flexible, opportunistic feeder that can easily adapt to varying habitat, season, insect community, vegetation structure, and time of day. The diet consists largely of [[caterpillar]]s, [[moth]]s, [[flies]], [[leafhopper]]s and [[planthopper]]s, small [[wasp]]s, [[beetle]]s, [[aphid]]s, [[stoneflies]] and [[spider]]s. Few berries and seeds are consumed, but are most often from [[barberry]], [[serviceberry]], and [[magnolia]].<ref name="Cornell"/>
