Objectifs
1)To quantify forest habitat selection by Olive-sided Flycatchers in forests of Northwestern California, 2) To obtain demographic information on the species through nest monitoring and mark-recaputure techniques, and 3) To examine habitat selection and alteration of wintering grounds.

Descriptif
General surveys for Olive-sided Flycatchers using point counts along roads will be conducted. Roads will be chosen to provide adequate coverage of each forest type. Each location will be recorded on a map and entered into a GIS data base for landscape level habitat analysis. At each bird location tree basal area, canopy cover, tree species, dbh, height and decay class of the perch tree, distance from the nearest forest edge, the size of the forest opening and the type of opening (clearcut, water, pasture, road, etc.) If the opening is a clearcut, the age of the cutting will be determined. Identical information will be recorded at random sites. Random sites will be located by following a random angle and a random distance from the occupied site. Differences in habitat features between occupied and random sites will be analyzed using paired logistic regression analysis. These analyses will provide insight into the habitat features associated with sites occupied by Olive-sided Flycatchers and identify forest management practices that will benefit flycatcher populations.
