Summary
Description
This report is about an investigation that was done to determine the quantity and species of submergent vegetation in the marsh area on the Canvasback Gun Club in Nevada. During the month of August, 1962, an aquatic habitat investigation was conducted on the Canvasback Gun Club by Bureau of Sport Fisheries and Wildlife personnel. The purpose of this investigation was to determine the quantity and species of submergent vegetation on the area, and to compare these findings with data collected during similar surveys in 1960 and 1961. Most of the marsh area of the Club remains in a mature stage of marsh evolution which offers little of value to waterfowl. Only a few of the smaller, relatively young ponds are producing waterfowl food in appreciable quantities. Most of the marsh remains virtually barren of any submergent plant growth of value to waterfowl.

Summary
Description
This report summarizes ten studies that were conducted in the coastal waters of Port Frederick. By means of simultaneous boat and plane surveys, investigators hoped to determine: the proportion of various species of waterbirds detected and counted by boat survey crews, which are also detected and counted by air survey crews; the variability of both boat and plane surveys, and the degree of annual variation in the percentage of birds counted from the air; and the feasibility of applying correction factors to aerial survey data gathered over an extensive area of southeast Alaska. The results are discussed.

The attached field diary notes provide documentation of walrus parts collection activities which occurred in the Nome and surrounding area during the periods of May 58 and May 21June 9, 1980. The notes include a description of the area, weather, ice conditions, problems encountered and recommendations for similar efforts in the future. The total result of the collection effort in Nome were: 3 stomachs; 3 reproductive tracts, and 8 pair of teeth.

Summary
Description
The objective of this work unit is to measure the energy requirements of moose during different seasons and for different sex and age classes. Techniques employed will permit partitioning of the energy contained in plants into various components down to net energy available for production. This information, along with data collected on forage supply and quality in a companion study, will be used in a mathematical model which can predict the capacity of the Kenai National Moose Range to support moose. This report summarizes the work completed prior to May 1981. Results include food intake rates, digestion trials, rumen turnover time, seasonal energy expenditure, methane production, simulation modeling, and energy partitioning.

This report summarizes changes in the population of deer in Alaska. The objectives of deer management in Alaska are to promote maximum utilization of our deer herds with the greatest return in recreation and with continued productivity. Predation, hunting, browse, winter mortality, and overall health are discussed in this report.

Summary
Description
This report summarizes the results of a breeding ground survey in Alaska during the 1965 breeding season. This year 206 of the 214, 16 mile transects laid out for breeding pair survey were completed in 101 flying hours by 180 Cessna. The survey showed a 27 decrease in breeding duck pairs from 1964 and a 28 decrease from the 10 year average. Duck production was very poor in 1964 due to the latest spring breakup on record followed by extensive flooding of nesting habitat so the reduced breeding population of 1965 comes as no surprise. The habitat this year appears to be in good shape and nesting began on schedule. What little data we have thus far, mostly for geese and swan, indicates high nest densities and large clutches so we may have a good chance of recovering the 1964 losses or at least producing a fall flight comparable to 1964.

Description
This report covers foxes on Amchitka and surrounding islands. Foxes were introduced to the island, which decimated the Aleutian Canadian goose. Predator control for the foxes is main topic of the report, so that the goose population could return to before fox introduction.

This report summarizes the results of a seabird fledgling success study that took place from August 26th to September 8th, 1989. Nest burrows were examined, seabirds were banded, transect surveys were taken, and stomach oil samples were collected. A description of the study area and methods used are discussed. Recommendations are also given. Data forms and maps of the study area are attached.

Charles L. Braley 1958 reported a drastic decline in a bald eagle Haliaeetus leucocephalus population during the late 1950s. He documented a marked reduction in the number of breeding pairs and the reproductive rate of the remaining pairs. In response to increasing concern for the future of the species, the National Audubon Society began to investigate the bald eagle over most of its range in 1960. The studies reported here have been closely coordinated with, or are integral parts of, a long term program to determine the status and examine the ecology of the bald eagle.
