The Olive-sided Flycatcher
is most often observed as it perches high in the tree tops, giving out an
occasional pip-pip call and flying out to capture flying insects. While
they are generally reclusive and solitary, they will vigorously defend their
nesting location from intruders.
Habitat: Primarily found in conifer forests,
especially near clearings along burned areas, rivers and lakes, and
Diet: Feeds almost exclusively on flying insects,
especially bees, wasps, winged ants, and items as large as cicadas and large
Behavior: Nearly always catches insects in flight,
observing from a perch and flying out to capture flying insects passing by.
Breeding: There are no definite records of
breeding within South Dakota, but there have been several breeding season
observations in the Black Hills (see "Birds of South Dakota", SDOU,
Song: Song is often described as "quick three beers", with
the second note higher.
Migration: Summers throughout much of the southern half of Canada, the upper Great Lakes,
New England, and in higher elevations and near the coast in the western United
States. Primarily winters in South America, with a few in Central America.
Conservation Status: Olive-sided Flycatchers have
shown decreases in population over the last several decades, a pace of
decrease which may have increased in the last 20 years. This may be
due to loss of habitat in its wintering grounds in South America.
