This report looks at marsh bird population trends within the marshes of Vermont, and investigates the effect of water level and marsh vegetation changes on marsh bird numbers. Relationships between various marsh bird nesting patterns are discussed as well as correlations between black tern nesting locations and water level. Recommendations are made for management activities which could benefit the black tern nesting population.

Summary

Description

Phragmites control was initiated during the second week of September this year. The pesticide applied was RODEO. Application was by helicopter flying very low over the targets, because of windy conditions. Targets consisted of 175 acres of Phragmites inside CPooll, CStorage Pool, BPool, GPool in newly hydroaxed areas, along the bayshore fingers, near the False Cape State Park boundary, and on a southern Ragged Island marsh island.

Summary

Description

A total of 136 geese were captured on Buldir. Four died in the transplant efforts. One bird died during transport and three died on Amchitka. The birds that died represented a three percent mortality factor for all the birds captured and transplanted. A total of 132 Aleutian Canada geese composed of 74 goslings and 59 adults minus one bird, age unknown were successfully transplanted and released on Amchitka Island. Continuation of transplant efforts on Amchitka or other foxfree islands will lead to the reestablishment of nesting populations of this endangered subspecies on Amchitka and other islands and hopefully lead to this eventual removal from the endangered species list.

Summary

Description

This study was conducted in June 1987 on Adak Island, Alaska, at two sites in the Clam Lagoon area. The primary objectives of the Aleutian tern Sterna aleutica study were to delineate colony boundaries, determine the population size of the colony, determine activity periods and nesting phenology, develop methods that can be repeated in future years and record all abnormal disturbances. The Aleutian tern is a summer visitor to Adak Island, arriving in late May and departing in mid to late August.

Summary

Description

Maquam Bog contains Vermonts largest populations of pitch pine, rhodora and chain fern, a statethreatened species. Dendrochronological methods were used to examine the ecological effects of fire and seasonal fluctuations in lake level on growth of pitch pine and distribution of shrub vegetation in the bog. Results indicate that fire plays an important role in determining present vegetation patterns in the bog, probably by reducing cover of tall shrubs, excluding fire intolerant species from recently burned areas, and allowing periodic reproduction of pitch pine. Prescribed burning should be considered in management plans if it is desired to maintain the bog in its present condition, and to ensure survival of its rare species.

Summary

Description

Preliminary observations on bear predation on pink salmon and red salmon, bear population of Kodiak Island, and efforts to reduce predation using electric fencing. Poor salmon returns and disinterest of bears prohibited collection of data on pink and red salmon predation. Electric fencing proved effective against bears.

The objective of this project was to determine if conspecific devices playbacks, decoys are effective in attracting upland sandpipers to suitable habitat sites. The conspecific attraction devices used were a timed playback with upland sandpiper vocalizations and upland sandpiper decoys.

Summary

Description

Management districts will be used as a tool to manage the population of bear on Kodiak Island. Theoretically, 204 bear may be taken off the refuge annually without undue harm to the population. Hunting will be allowed according to the regulations of the Alaska Game Commission. Electric fence should be used as an exclosure to bear on the small red salmon streams. Any ranching expansion should be limited to the area on the Chimiak Peninsula and on the small islands outside of the refuge. Cooperation will be extended in every phase of the bearcattle problem within reason and policy. The most desirable type of control in the ranching area is a control that requires only a small amount of attention. It is recommended that the road from middle Bay to Saltery Cove be repaired and put into useable condition, to increase activity in the ranching area.

Summary

Description

As part of ongoing research into the status of Vermonts marsh birds, a statewide census of the black tern nesting population was undertaken again in the year 2000. The recent trend of higher percentages of black tern nesting concentrated at the north end of Lake Champlain continued in 2000, with all nesting being in and around the Missisquoi National Wildlife Refuge. This is a large protected wetland complex so it is probably the best area in Vermont for terns to concentrate. This report takes a look at marsh bird population trends within certain marshes in Vermont, and investigates the effect of water level and marsh vegetation changes on marsh bird numbers.

Summary

Description

The black tern is a colonial nesting marsh bird which has been declining significantly in numbers throughout its range, and in particular in the Northeast. In Vermont the population has declined approximately 50 since the 1970s. This report outlines and discusses census results for the past few years 19901992 and offers perspectives on future research and management options.

Summary

Description

Survey of whitefronted geese and Canada geese within Koyukuk NWR and Kayiuh Flat Unit, Innoko NWR, July 16August 8, 1985, counting 5,857 plusminus 3,127 adult and 660 plusminus 448 young white fronted geese. The highest densities of geese were along the river corridors. No geese were observed in the Kaiyuh Unit.

Summary

Description

A total of 136 geese were captured on Buldir. Of this number, 11 died in capture or transplant process. The birds that died represented an eight percent mortality factor for all birds captured and transplanted. Three birds of the eleven died after release on Amchitka. One additional adult bird escaped prior to transplant. 124 Aleutian Canada geese 96 goslings and 28 adults were successfully transplanted and released on Amchitka Island. The capture and transplant of wildlife Aleutian Canada geese from Buldir Island is the most efficient method for reestablishing nesting populations of this subspecies on islands cleared of foxes where the geese historically nested, prior to introduction of foxes. Eleven nests were found on Agattu Island proving the success of previous transplants to that island.

Summary

Description

A survey for nests of Aleutian Canada geese Branta canadensis leucopareia was conducted at Agattu Island in June 1990. The coastal fringe on the eastern and southeastern portions of the island contained at least 5356 nests, and we estimated that over 200 nonbreeding geese may have been present. Most pairs began incubation during the last week of May and the peak of hatch occurred the last week of June. The average clutch contained 6 eggs, and at least 77 of the eggs hatched. At least 1 egg hatched in nearly 95 of the nests, so overall productivity in 1990 was excellent.

Summary

Description

Geese were captured on Buldir Island by searching the upper and lower edge of the lowland tall plant association where tall plants offer cover and short plants offer succulent food. When the geese were captured, they were sexed, aged and banded with a numbered colored plastic leg band and size 7B FNS leg band. Within 72 hours after capture the birds were transported to Agattu via the charter vessel Vestfjord and released at Goose Creek in Aga Cove, Agattu Island. A total of 92 geese were captured on Buldir. Of this number, four died in the capture or transplant efforts. The four birds that died represented a four percent mortality factor for all the birds captured and transplanted. A total of 88 Aleutian Canada geese composed of 56 goslings and 32 adults were successfully transplanted and released on Agattu Island. The capture and transplant of wild Aleutian Canada geese from Buldir Island is the most efficient method for reestablishing nesting populations of this subspecies on islands cleared of foxes where the geese historically nested prior to the introduction of foxes near the turn of the century. This was confirmed earlier this summer when three nests and one brood were found at Cape Sabak, Agattu Island. Continuation of transplant efforts will lead to reestablishment of nesting populations of this endangered subspecies on Agattu and other islands and hopefully lead to the species eventual removal from the endangered species list.
