The olive-sided flycatcher (Contopus cooperi) is a fairly common breeder in northern New England, rarer in the southern part of BCR 14. It prefers high-elevation spruce-fir forests or the borders of northern bogs and muskegs. It needs tall exposed perches near openings of various sorts. It is listed as a Species of Greatest Conservation Need in one or more states in BCR 14.



This bird is an insect-hawker so high exposed perches from which to hunt bugs are an important element of its habitat. These perches can be dead or alive in and around coniferous forests, usually at higher elevations, or adjacent to bogs, muskeg areas, stream borders, or clearcuts.

Its territory size ranges from 4 to 8 acres.


The key to managing for this species lies in the retention of dead or alive perch trees in softwood clearcuts and around bogs and other riparian areas.

When assessing a property for habitat potential, look for poorly drained high-elevation soils in Important Forest Soil Groups IIB such as Bemis, Cabot, Monarda. Soils at lower elevations also in Important Forest Soil Groups IIB include Lyme, Moosilauke, Pillsbury, Ridgebury or Stissing. There are other applicable soil series depending on the location in BCR 14.
