Both pelagic and land based bird observations are included. The bulk of the pelagic cibservations compiled here were gathered while conducting a series of 32 9uantified pelagic censuses to doc0men~ the dist~ibution, abundance, and biomass of seabirds along the Aleutian Island chain. Land based observations were primarily made while conducting beach surveys along established t~outes on Kiske., and as incidental obset~vations m.::1de while L"<2_nc.iucting more intensive fieldwork aimed at determining the status of Aleutian Canada g~ese on Agatt~ and while searching for fox sign on Kiska. The objectives of this report are: (1) documentation of observations of rare birds (2) documentation of nesting records and (3) docum~ntation of bird abundance and distribution information for the I island and refuge checklists. r; ! : ARLIS Alaska Resources Library & Informatton Servtces Anchorage, Alaska i! We c6mp1eted an average of·lo- 12_hours of pelagic and/or land based bird observations each day. All pelagic bird o~servations were made from the 121 foot U.S. ~ish and Wi~dlife Service research vessel M/V Tiglax TC~ptain,· ~lvin Bayer) while enroute between islands. Sufficient instrumentaion was available for the collection o·F numt?r'ou~; var' i ab 1 es of mensLWC:ll da tc:1 potentia 11 y use·Fu l for the analysis of pelagic ~;;eat:lir'd distr'ibution and abundance patteffis. An extensive description of the methods of data collection used for these pelagic censuses is contained in Gould and Forsell (1986). Land based bird observations were made on foot and from an inflatable boat while enroutc between the research vessel and the islands. Previously established beach transects (Dienes, 1986) were surveyed north of Kiska Harbor (including Salmon Lagoon) and in the Kiska Harbor region (excluding Trout Lagoon). Other land bird observations were made in the Gertrude, Mutt, and Jeff Cove regions of Kiska and on southeastern Agattu between Karab Cove, Aga Cove, and Cape Sabak. We also landed at two locations on Amchitka and on southern Adak and obtained some data from these locations as well.

Abundance values are those described by Zeillemaker <1987a) and are as follows: abundant very numerous species common certain to be seen in suitable habitat uncommon present, but not always easy to find rar'e seen only a few times during indicated season occ~"lsional seen irregularly over a two to five year span accidental found once/twice during season since the 1880's We subjectively applied these criteria to observations made by us on this trip. An asterik is used to designate evidence of breeding we observed (including the observation of nests, fledglings that had not yet gained the capibility of making interisland flights, or adults which were obviously carrying food to nests>. Pelagic observations were assigned to the island closest to where the observations were made since all observations were less than 100 miles· from the nearest island. .. ·······-- -··----4----'-----·-----------·---·-.-- .... ,,. ........
