I photographed this Eastern Kingbird at the Sequoyah National Wildlife Refuge in Oklahoma yesterday. They are common in this refuge. I have tried for years to photograph one of these birds catching insects. They are very quick.
Eastern kingbirds wait on an open perch and fly out to catch insects in flight, sometimes hovering to pick food off vegetation. They also eat berries and fruit, mainly in their wintering areas.
