Spring: Olive-sided Flycatchers are uncommon visitors to the Washington metro area, and there are only five spring records for them at Monticello Park.
Fall: An Olive-sided Flycatcher has never been recorded at Monticello during the fall.
Where to See Them in the Park
On the rare occasions when an Olive-sided Flycatcher is at Monticello, it usually is on a bare branch at the top of a tall dead tree. There is no best time to look for one.
In May, 2017, an Olive-sided Flycatcher visited Monticello. This composite photo shows three images of the underparts. The breast has a broad central lemony line, and the olive sides are long vertical streaks which border the central line on each side. The sexes are similar.
The rump has white tufts on each side. A birder who used to visit the park referred to these tufts as "white fluffies".
Olive-sided Flycatchers hawk insects from high open perches. The 2017 bird at Monticello caught a cicada and swallowed it, wings and all.
This photo shows the flight and wing feathers of the Olive-sided Flycatcher on one of its sallies to catch insects.
The song of the Olive-sided Flycatcher has one of the best-known bird mnemonics — a loud, emphatic QUICK, THREE BEERS!.Hear the song of the Olive-sided Flycatcher.
Mnemonics can help people to remember birdsong, because many people more easily remember words than sounds. Sometimes, a species can have more than one mnemonic for the same song, because different people can hear the same sounds differently.
