The California quail, Callipepla californica, is one of Americaʼs
most interesting game birds. It is easily recognizable by its loud calls
and by the clump of feathers on its head called a topknot. Over the years, this bird has been given several common names,
including California quail, valley quail,
and...
Seasonal diet and food selection of California quail (Callipepla
californica) were studied at E.E. Wilson Wildlife Area, Oregon,
during 1985 to 1987. Analysis of diets of 105 quail, along with
information from 117 quail taken during 1976 to 1978 revealed 14 key
plant foods. Collectively, the key foods composed 87%...
A partially automated radio-tracking system with semi-continuous
azimuth data collection and XYLOG5 and MAP computer programs for azimuth
data analysis was used for studies of California quail (Callipepla
californica) at the E.E. Wilson Wildlife Area, Oregon, in 1988 and 1989.
Movements of 58 hens were monitored daily to determine nest...
The effects of disking, food plantings, and wheat plantings on a population of California quail (Lophortyx californicus) were studied from fall 1976 to spring 1978 on the E.E. Wilson Wildlife Area, Oregon. Twelve 16.2-ha study sites were established: 3 study sites for each treatment and 3 control sites. Disked areas,...
Mountain Quail (Oreortyx pictus) populations have declined in many areas of the western Great Basin during the past century. Yet the life history of this species is little known. From 1997 to 2000, I studied radio-marked Mountain Quail in Hell's Canyon in northeastern Oregon, in the Cascade Mountains of southwestern...
A genetic selection study to determine the effects on egg hatchability and subsequent chick performance of Japanese quail (Coturnix japonica) eggs incubated at 100 F dry bulb temperature (Control, Line C) when compared to other eggs incubated at 102 F (Selected, Line S) was conducted over 10 consecutive generations. Eggs...
Mountain Quail (Oreortyx pictus) populations have declined in the eastern portion of their range during the last century. However, few studies have investigated the nesting habitat and survival of Mountain Quail translocated into an area from which they have been extirpated. We translocated 217 wild Mountain Quail (Oreortyx pictus) from...
