We estimated the density of 4 populations of mountain quail (Oreortyx pictus) in northern California during the breeding season (May-Jun) 1983. Estimates of density (D̂) were obtained from Fourier series analyses of perpendicular distance data. D̂ values ranged from 9 to 30 quail/100 ha, with associated coefficients of variation (CV) <20%. Percent relative density values calculated from the estimates of D̂ compared favorably with percent relative number of quail detected/km of transect. In general, mountain quail were behaviorally compatible with line transect sampling.
