are Passerine birds which occur throughout North and South America. They superficially resemble the Old World flycatchers, but are more robust and have stronger bills. They do not have the sophisticated vocal capabilities of the songbirds. Most, but not all, are rather plain. As the name implies, most are insectivorous.
