Bird Checklists of the United States

Walrus Islands State Game Sanctuary

Round Island, Alaska


C - Common - species occurs in all or nearly all proper habitats, but some areas of presumed suitable habitat are occupied sparsely or not at all or the island regularly hosts large numbers of the species.

U - Uncommon - species occurs regularly, but uses only some or very little of the suitable habitat or the island regularly hosts relatively small numbers of the species; not observed regularly even in proper habitats.

R - Rare - species occurs, or probably occurs, regularly on and near the island, but in very small numbers.

A - Casual/Accidental - species has been recorded no more than a few times, but irregular observations are likely over a period of years or a species so far from its normal range that further observations are unlikely.

* - Nesting - known or probably nesting species on Round Island.

Any birds listed as "rare" or "casual/accidental" on this list, and any evidence (nest or chicks) for a bird not listed as a breeding species, should be shown to Round Island staff for verification. If a bird not included in this checklist is seen, it should also be verified.

To document a sighting you may take a photograph, using a telephoto lens. Whether or not a photo is taken, you should take a very careful look at the bird remembering as much detail as possible. Point out the bird to others without saying what you think it is. If possible, compare notes while looking at the bird after other observers have had a chance to identify it. Before checking a field guide, write a brief description and sketch the bird showing the pattern of markings and labeling colors. Then check your field guide to confirm your sighting. Report unusual sightings to Round Island staff as soon as possible.

Bird species inhabiting Round Island are relatively well known. Lists of birds observed during summer field seasons have been compiled by the following researchers and staff residing on the island: E.H. Miller and B. Hines (1972), J. Sherburne (1985, 1986), J. Sherburne and B. Lipchak (1987), P. Hessing and J. Brandt (1988), and P. Hessing and G. Sheffield (1989, 1990). The lists were generally compiled from May to August.

Relative abundance is les well known. Only Miller, Aumiller, P.D. Arneson and D. McDonald (1976, 1977), and R.J. Sinnott (1990) have attempted to quantify abundance. Hence, this checklist should be considered provisionary. Similarly, additional nesting attempts and casual/accidental vagrants are likely to be observed. Hopefully, this list will focus future attention on the birds of Round Island, and it will be updated periodically as new observation are collected.

Round Island seems to attract fewer unusual birds than islands in the western Aleutians, and many of the species on this list are casual or accidental vagrants that are unlikely to be encountered by visitors. If you are hoping to see some of the more typical birds of western Alaska (such as jaegers), plan to spend at least a few hours birding in the vicinity of Togiak Cannery and Dillingham
