Breeding chronology, habitat utilization and nest-site selection of the long-billed curlew in northcentral Oregon

Creator:: Pampush, Geoffrey J.
Abstract:: Breeding ecology of long-billed curlews in Umatilla and Morrow Counties, Oregon, was studied during the spring and summer of 1978 and 1979. The first curlews were observed in the study areas on 16 and 19 March of 1978 and 1979, respectively. Earliest clutch completion and onset of incubation was on...

Ecology of harlequin ducks in Prince William Sound, Alaska, during summer

Creator:: Dzinbal, Kenneth A.
Abstract:: Harlequin ducks (Histrionicus histrionicus) were observed during the summers of 1979 and 1980 in Sawmill Bay, northeast Prince William Sound, Alaska. Harlequins were associated with a short, medium gradient, non-glacial stream (Stellar Creek) also used by salmon. Although harlequins nested along Stellar Creek, they apparently did not establish home ranges...

The relative effects of Ceratomyxa shasta on crosses of resistant and susceptible stocks of summer steelhead

Creator:: Wade, Mark
Abstract:: Crosses were made between a stock of summer steelhead (Salmo gairdneri) known to be resistant to infection by Ceratomyxa shasta and stocks of summer steelhead known to be susceptible. Ceratomyxosis, the disease caused by C. shasta was initiated by exposure to Willamette River water. I found that the crosses were...

Habitat relationships of birds and young-growth Douglas-fir in northwestern California

Creator:: Marcot, Bruce G.
Abstract:: Ninety-one species of birds were surveyed in grass/forb, early and late shrub/sapling, pole, and medium sawtimber stages of young-growth Douglas-fir in northwestern California; patterns of bird distribution and abundance were related to habitat conditions and even-age silvicultural treatments. Seven species (band-tailed pigeon, western wood pewee, dusky flycatcher, western bluebird, fox...
