Least Flycatchers are the smallest Empidonax flycatcher in the East. Like other flycatchers they tend to perch upright, but they appear a little more compact than most. The primary feathers on their wings are short, which makes their thin tail look longer. Their head is round and is not peaked at the back of the head like some other Empidonax.
