Summary
Description
This paper summarizes the results of the third of a fiveyear study on the breeding biology and habitat requirements of geese nesting at Kokechik Bay, Alaska. Data were collected from May 1st to July 7th, 1984. The primary objectives of this field season were to: observe the behavior of emperor geese and cackling Canada geese in spring; continue the study of the comparative nesting ecology of geese, with emphasis on how the choice of habitat varies between species and among successful and unsuccessful nesting pairs; continue the study of clutch size in emperor geese emphasizing the occurrence of intraspecific nest parasitism and factors influencing its occurrence; and the incubation behavior of geese and the ecological significance of that behavior.

Summary
Description
Spring walrus harvest data and biological samples 177 pairs of teeth for aging, corresponding sternal skinblubber thickness and tusk length measurements for health studies, and tissue samples for contaminant analysis were collected in Gambell, Alaska from 22 April through 6 June 1981. Analysis of biological samples is in progress. Retrieved harvest consisted of 961 walruses 36 males, 39 females, and 25 calves. An average of 8.3 walruses were retrieved per hunter. Loss rates for animals shot in the water were between 618 for animals shot on the ice. Loss rates were highest for males and lowest for calves. Total harvest including possible sunk and lost was estimated to be between 1118 and 1301 animals. An estimated average of 55 of the walruses harvested were utilized solely for their ivory and an average of 45 were utilized for other parts along with the ivory. Percent utilization of specific walrus parts varied highly by the type of part but was highest for calves 100 and lowest for vibrissae 1. Herd size was found to affect an animals vulnerability in beingharvested. Animals in herds of 12 were most vulnerable 90100 retrieved. Vulnerability dropped as herd size increased and males in all male herds were found to be less vulnerable than females in femaleyoung herds. Of all factors, wind velocity affected hunting occurrence and success the most, followed by ice conditions, and then by weather fog, rain, snow. During the migration male walruses predominated to the E and NE of Gambell and to the NW close to the Siberian coastline. Females, subadults, and calves predominated to the N and NW in the middle of Anadyr Strait. The height of the harvest and probably the migration occurred between 12 and 23 May. The ice pack was substantially broken up by this time, allowing hunters better access to walrus and allowing walrus an open path through Bering Strait.

Description
The second coordinated U.S.U.S.S.R. aerial survey of walruses was completed in September 1980. The first was undertaken in September October 1975. In 1980, surveys undertaken by the U.S. side were done on 10 to 20 September. The results of this survey indicate that there were an estimated 140,000 plus walruses east of 173 W longitude at the time of the survey. A concurrent survey undertaken in regions west of 173 degrees W by Soviet scientists resulted in an estimate of 130,000 to 150,000, suggesting a total estimate of 270,000 to 290,000 Pacific walruses in 1980.

Summary
Description
Three observers disembarked the 86 charter vessel Western Pacific near the east end of Nizki Island 23 May 1983. The goal of the field camp was to observe Aleutian Canada geese and inventory all migratory bird populations on the islands for the first time since introduced foxes were eliminated from the island in the late 1970s. On 23 May, two observers were placed in a field camp at Aga Cove Aggatu Island, for the purpose of locating and observing returning Aleutian Canada geese through 3 June 1983. In total, geese were sighted 100 times. Thirtythree sightings were rebanded birds where the band numbers could be read and recorded. Seventeen sightings were of unbanded birds. Six were of birds known to have bands, which were unreadable. The remainder were of birds observed under circumstances which precluded determination of banding status. One pair of leg and other bones was also found near Cape Sabak. Evidence suggested the bird died shortly after being transplanted to Agattu from Buldir last summer.

1962 status of waterfowl as presented to the Waterfowl Advisory Committee, Washington, D.C., August 1962

Summary
Description
Because lesser number of ducks were expected to come South in the fall of 1961, shooting regulations were restricted to reduce the kill. Surveyed revealed that regulations reduced duck kill in the United States from 9.6 million in 19601961 to 63 million in 19611962. Nonetheless, the breeding duck population index was reduced by 3.5 million birds compared to 1961. The duck population was overharvested in fall 1962.

Aleutian Canada goose survey at Nizki and Alaid Islands, Near Islands group, Aleutian Islands, spring 1983: Final report

Summary
Description
Introduced Arctic foxes were eliminated from Nizki and Alaid islands in the late 1970s. Due to the unavailability of a support vessel, mainland reared Aleutian Canada geese were transplanted from an aircraft at nearby Shemya Air Force Base to Camp Cove at Nizki by inflatable boats on 15 August 1981. Only three geese from the 1981 release at Nizki Island were found in 1983. Those three birds were among the birds found on the island in May 1982. Although one of the birds was an apparent loner, birds 728 and 734 were found together with other birds until 28 May when 728 and A92 from the 1982 BuldirAgattu transplant were found alone together at Camp Cove for the first time. They remained together until our departure from Nizki at 1700 on 3 June 1983. There were no observations of nesting activity during the investigations.

1965 status of waterfowl as presented to the Waterfowl Advisory Committee, Washington, D.C., August 10, 1965

Summary
Description
A decrease in breeding population was recorded in most survey areas as compared to 1964. The aerial breeding population indices by areas, shown in table 1, have not been corrected for birds present that were not seen by aerial crews. Using the results of the airground comparison studies to adjust the aerial index figures for birds not seen provides a somewhat different estimate of the change between 1964 and 1965. The adjusted total suggests that between 1964 and 1965 the duck breeding population decreased from about 35,588,000 to about 27,500,000, a decrease of 23 percent. The 1965 index is 42 percent below the peak number reached in 1956 and 28 percent below the average of the previous 10 years. It is 8 percent below the 1962 index, which was as low as the breeding population should be allowed to go.
