AIF No. 6 DRAFT 2. presented in a later report summarizing data from all trips. The few species discussed below are either uncommon visitors to the area or land birds. American Widgeon - Anas americana - Two females collected on Palmyra. European Widgeon - Anas penelope - One female collected with the two American widgeons. Shoveler - Spatula clypeata - One female was collected and another male and female were seen on Palmyra. Four species of duck have been recorded from Palmyra and the shoveler has been recorded on all three visits. The Island Manager on Washington reports that large numbers of ducks arrive there in the fall but we found only one duck present in November. Sanderling - Crocethia alba - Two were collected on Christmas Island and the species was recorded on Birnie (1), Enderbury (2), Jarvis (1), Washington (2), and Palmyra (5). Sharp-tailed Sandpiper - Erolia acuminata - This species was collected on McKean (1 of 5), Gardner (4 of 5), Sydney (1 of 1), and was identified on Palmyra (3). These records and the similar ones from last year establish these two categories of sandpipers as regular, but uncommon visitors to our area. Laughing Gull - Larus atricilla - One adult was collected and a sub- adult bird was observed on Palmyra. The large influx of Laughing Gulls into the Central Pacific last year was exceptional (this species was not previously recorded) and the birds seen this trip probably belong to that group rather than to a new invasion by this species. Chicken - It is domesticated on Christmas and Washington Islands and wild on Palmyra (1) and Gardner. A small but flourishing population, 20 adults and 10 chicks seen, is concentrated in the NW corner of Gardner Island. Line Island Parrot - Psittacula kuhlii - this is a common and con- spicuous bird on Washington Island. Populations established in the past on Christmas, Fanning and Palmyra are now extinct.
