|This species was once regarded as a very rare transient in the state, but it is now recorded with considerable regularity, particularly in late summer and early fall. In spring it is still looked upon as a rare and late migrant, having been recorded less than a dozen times, once on April 22 and all other times between May 2 and 23. Fall records, now numbering over 30, range from July 31 through October 20, with all but four of the observations being in August and September.|
|The species breeds in coniferous forest, across the entire breadth of Canada and the United States and even southward along the Alleghenies. It winters in South America from Colombia and Venezuela to Peru.|
The Olive-sided Flycatcher is a rather large-headed, chunky flycatcher, about the size of an Eastern Bluebird. Above it is dark greenish fuscous, and the breast has a dark grayish patch on either side, separated by a white streak passing through the throat to the lower belly. A tuft of white feathers usually protrudes on each side from beneath the wings near the base of the tail. Although the Olive-sided Flycatcher might conceivably be confused with the Eastern Wood Pewee, the latter is not so heavy breasted and chunky, nor does it have the white tuft on each side of the base of the tail. The note of the Olive-sided Flycatcher is an emphatic three-syllabled "Come right here, or "Hip, three beers."
