Letter from the Desk of David Challinor August 2001 About 1,000
Letter From the Desk of David Challinor August 2001 About 1,000 miles west of the mid-Atlantic Ridge at latitude 32°20' north (roughly Charleston, SC), lies a small, isolated archipelago some 600 miles off the US coast. Bermuda is the only portion of a large, relatively shallow area or bank that reaches the surface. This bank intrudes into the much deeper Northwestern Atlantic Basin, an oceanic depression averaging some 6,000 m deep. A few kilometers off Bermuda's south shore, the depth of the ocean slopes precipitously to several hundred meters. Bermuda's geographic isolation has caused many endemic plants to evolve independently from their close relatives on the US mainland. This month's letter will continue the theme of last month's about Iceland and will illustrate the joys and rewards of longevity that enable us to witness what appears to be the beginnings of landscape changes. In the case of Bermuda, I have watched for more than 40 years a scientist trying to encourage an endemic tree's resistance to an introduced pathogen. My first Bermuda visit was in the spring of 1931. At that time the archipelago was covered with Bermuda cedar ( Juniperus bermudiana ). This endemic species was extraordinarily well adapted to the limestone soil and sank its roots deep into crevices of the atoll's coral rock foundation. The juniper's relatively low height, (it grows only 50' high in sheltered locations), protected it from "blow down," a frequent risk to trees in this hurricane-prone area. Juniper regenerated easily and its wood was used in construction, furniture, and for centuries in local boat building. -
SHORT-TAILED SHEARWATER Ardenna Tenuirostris Non-Breeding Visitor, Occasional Migrant Monotypic
SHORT-TAILED SHEARWATER Ardenna tenuirostris non-breeding visitor, occasional migrant monotypic The Short-tailed Shearwater breeds on islands off S and SE Australia in Nov- May, disperses northward through the W Pacific to the Bering Sea in May-Aug, and migrates rapidly southwestward in large flights across the central Pacific, back the breeding grounds, in Sep-Nov (King 1967, Harrison 1983, AOU 1998, Howell 2012). In the Hawaiian Islands, large numbers have been recorded during well-defined pulses in fall migration, and several sight observations of one to a few birds suggest a smaller passage in spring. The Short-tailed Shearwater is extremely difficult to separate from the similar Sooty Shearwater in the field (see Sooty Shearwater), especially when viewing isolated individuals (King 1970); thus, confirmation of the spring passage with specimen or photographic evidence is desirable. Short-tailed Shearwater was placed in genus Puffinus until moved to Ardenna by the AOU (2016). At sea, Short-tailed Shearwaters were recorded in large numbers during 2002 HICEAS, with 37,874 individuals observed on 52 of 163 observing days from W of Kure to S of Oahu (Rowlett 2002; HICEAS data); they were observed from 1 Sep to 14 Nov. Over 1,000 birds were recorded on each of seven dates, with a large peak of >28,000 recorded 13-22 Sep 2002 between Midway and Lisianski and a smaller peak of >4,000 recorded 30 Oct-14 Nov between Laysan and Kaua'i. All birds were flying SSW in concentrated groups. In contrast to Sooty Shearwater, Short-taileds were clearly more abundant in Northwestern than Southeastern Hawaiian Island waters during fall passage; only 66 birds were recorded on 3 of 35 dates during this period off the Southeastern Hawaiian Islands. -

Franke College of Forestry and Conservation, University of Montana, 32 Campus Drive, Missoula, Montana 59812, USA ABSTRACT: Pelagic seabirds are important components of many marine ecosystems. The most abundant species are medium/small sized petrels (<1100 g), yet the sub-mesoscale (<10 km) distri- bution, habitat use and foraging behaviour of this group are not well understood. Sooty shearwaters Ardenna grisea are among the world’s most numerous pelagic seabirds. -

G. FRANZ SAUER, Gainesville, Fla., and EMIL K. URBAN, Madison, Wise. The avifauna of St. Lawrence Island, in the Bering Sea midway between the Old and the New Worlds, and about 400 km south of the Arctic Circle, was admirably summarized to date by Fay and Cade (1959). During our work there with Golden Plovers from 2 June to 28 August 1960 (Sauer, 1962), we made sundry observations on 57 other species that seem worth recounting as complimentary or additional to the Fay and Cade data. These add nesting records for five species to the island. Most of our obser- vations were restricted to the Boxer Bay area, but our records also include bird notes made on overland and boat trips from Boxer Bay to Gambell and to the western margin of Koozata Lagoon (Fig. 1). 171°30' Fig. 1 a, b.
