The olive-sided flycatcher is a tyrant flycatcher that breeds primarily in the coniferous forests of North America. Their breeding territory consists of most of Alaska and Canada, plus the Rocky Mountain and Appalachian Mountain regions. They winter as far south as central South America. Since they have such a long migration they usually arrive at the breeding territory later then other species and leave earlier. This pic was taken at the beginning of September at the Carpenter Nature Center. Since we do not have the proper breeding habitat for this species, except in the north east corner of the state, I assume that this bird was migrating south and stopped for a lunch break. Olive sided flycatchers almost exclusively eat flying insects. They typically find a perch that is in the open and wait to ambush an insect as they fly by. I watched this one catch and eat several bees, which are one of their main prey species. They also eat wasps, flying ants, moths, grasshoppers and dragonflies.
