Status of a translocated sea otter population and its habitat in Washington

During the summers of 1969 and 1970, the Alaska Department of Fish and Game and the Washington Department of Game translocated 59 sea otters from Amchitka Island, Alaska, to release sites in Washington (Jameson et al. 1982, Wildl. Soc. Bull. 10:100-107). Of the 29 released near Pt. Grenvil (Fig. 1) in 1969, 16 are known to have died. In 1970, 30 otters were held in a floating enclosure anchored near James Island, off La Push. They were released nearby in excellent condition on July 1970. Results of surveys from 1977 to 1981 were reported by Jameson et al. (1982). The purpose of this note is to report subsequent additional observations for 1983 and 1985 on the abundance, distribution, and habitat of the sea otter population in Washington

Recent Red-shouldered Hawk range expansion north into Oregon including first specimen record

In this paper we review 46 Red-shouldered Hawk ( Buteo lineatus ) observation records from Oregon between 1971 and 1983. The literature contained only two records prior to 1971: Johnson's (1880) record without a specific date or locality from the Willamette Valley of western Oregon, and Bendire's (1892) two nests located in 1878 near Camp Harney in eastern Oregon. Gabrielson and Jewett (1940) placed the species on the Oregon hypothetical list because they doubted the validity of the previous identifications. However, Browning (1973) measured the eggs collected by Bendire, reviewed his field notes, and concluded that there was ample evidence the species had occurred in Oregon despite the absence of records for nearly 100 years.
