Behavioral patterns and their temporal organization in breeding American Avocets

Creator:: Gibson, Flash
Abstract:: The organization of behavioral activities in time is important to a bird's survival and reproduction. To be successful, either proximately or ultimately, a bird must apportion its behavior in time so that it may obtain sufficient energy for maintenance activities and for such activities as migration and reproduction. The organization...

The water economy of the Sage Sparrow, Amphispiza belli nevadensis (Ridgway)

Creator:: Moldenhauer, Ralph Roy
Abstract:: This study investigated several physiological aspects of the water economy of the Sage Sparrow, Amphispiza belli nevadensis,as they relate to the ability of this species to inhabit xeric desert environments. When maintained in captivity on a dry diet without drinking water, Sage Sparrows gradually lost weight and died. During the...

Polygyny in the bobolink : habitat quality and the adaptive complex

Creator:: Martin, Stephen George, 1941-
Abstract:: The adaptiveness of polygyny in passerines poses a particularly intriguing problem. The altricial young of this group require extended parental care, but young of polygynous pairings generally lack the undivided attention of the male which young of monogamous pairings receive. Polygynous offspring may thus be undernourished and experience greater mortality....

Ecological relationships of birds in forests of western Oregon

Creator:: Anderson, Stanley H.
Abstract:: The avifaunal composition of ten western Oregon forest stands located at the eastern base of the Coast Range was examined on a seasonal basis. The stands were dominated by Oregon white oak, Douglas fir or western hemlock, Avian populations were sampled monthly from January 1968 to January 1970, using permanent...

The behavior of the pea crab Fabia subquadrata in relation to its mussel host, Mytilus californianus

Creator:: Lidrich, Joseph Stanley
Abstract:: The pea crab Fabia subquadrata is frequently found as a symbiont of mussels, living within the mantle cavity. This study examined the nature of this symbiotic relationship by recording the pattern of distribution of individuals in a mussel bed, testing responsiveness to host secretions, and observing the feeding mechanics and...

Singing behavior of the Bewick's wren : development, dialects, population structure, and geographical variation

Creator:: Kroodsma, Donald E.
Abstract:: The songs of the Bewick's Wren are discrete units of one to three seconds duration with intersong intervals several times the length of the song. Individual song repertoires at the William Finley National Wildlife Refuge, Oregon, range from 13 to 20 song types, and a given song type is repeated...

Resource allocation in four syntopic species of marine diving birds

Creator:: Scott, James Michael, 1941-
Abstract:: During 1969-1971 I studied patterns of resource allocation and behavioral interaction among Brandt's Cormorants, Pelagic Cormorants, Common Murres and Pigeon Guillemots in the area of a breeding colony on Yaquina Head on the central Oregon coast. Extensive studies of the breeding colony were combined with detailed observations of the distribution,...

Local adaptations in chipmunk (Eutamias amoenus) populations and evolutionary potential at species' borders

Creator:: States, James B.
Resource Type:: Dissertation

Influence of heat exchange on foraging behavior of Zonotrichia spp.

Creator:: DeWoskin, Rob
Abstract:: The heat exchange of individuals in a foraging mixed population of Zonotrichia leucophrys and Zonotrichia atricapilla in western Oregon is analyzed with respect to the direction of stance and feeding location. Values for heat gain or loss in the field were generated from a model that estimates the equivalent black-body...
