12 days during 1 1-25 July; M. Brown et al., unpublished) and at the Eek 

 River (1 to >15 birds per day on 11 days during 17-29 June 1985; 

 M. Brown et al., unpublished). Along the coast, we found breeding birds 

 at Goodnews Bay, Chagvan Bay, Cape Peirce, and Nanvak Bay; Bull (in 

 Friedmann 1933) collected an adult female at Goodnews Bay on 15 June 

 1933. Savannah sparrows nested at Round Island (T.J. Eley, unpublished; 

 E. H. Miller, unpublished; and P. D. Ameson and D. B. McDonald, 

 personal communication) and Crooked Island (P. D. Ameson and D. B. 

 McDonald, personal communication), and were suspected to nest at 

 Summit and Hagemeister islands in 1977 (?. D. Ameson and D. B. 

 McDonald, personal communication). 



Territorial savannah sparrows were found to 500 m asl in all open 

 habitats or boundaries between clearings and shmb, except wet dwarf 

 shmb mats, bare areas, and dry dwarf shmb mats. We found 5 0 pairs per 

 square kilometer in disturbed and 11.4 pairs per square kilometer in 

 undisturbed riparian plots at the Tuluksak River in 1983. In the open 

 habitats we sampled there, we found 2.3-3 0 pairs per linear kilometer. 

 At the Tuluksak River young fledged as early as 23 June 1974, but usually 

 fledged between 3 and 10 July in most years; movements of birds through 

 the area were evident on 1 4-1 5 August 1977, and no birds were recorded 

 after mid-August. 



Along the coast at Cape Peirce and Nanvak Bay, savannah sparrows 

 arrived on 4 May 1973 and 3 May 1976. A copulating pair was seen there 

 on 7 June 1970. Nests were found there with eggs between 20 June and 



13 July 1970, 1973, and 1976 (this study), on 15 June 1981 (one nest with 

 four eggs; D. H. Herter and D. Lloyd, personal communication), and on 

 21-30 June 1984 (A^= 8 nests; x = 4.75 eggs per nest; SE = 0.l6; range, 

 4-5; [D. R. Herter et al., personal communication]). Young were in nests 

 between 20 June and 13 July 1970, 1973, and 1976 (this study); between 

 20 June and 15 July 1981 (D. Lloyd and D. H. Herter, personal communi- 

 cation), and on 2 July 1984 (one nest with five young; D. R. Herter et al., 

 personal communication). Young fledged between 28 June and 1 6 July 

 1970, 1973, and 1976. Birds left the breeding areas by 3 September 1976, 

 and flocks were in the area from early August to 25 September. At Round 

 Island, a nest had four eggs on 1 1 June and another had five eggs on 

 15 June 1972 (E. H. Miller, unpublished); flail grown young were present 

 by 14 July 1974 (T.J. Eley, unpublished). At Chagvan Bay, pairs were first 

 evident beginning 26 May 1987 (D. F. Parmelee and J. M. Parmelee, 

 unpublished); at Goodnews and Chagvan bays, we found no young 

 between 11 and 20 June, but found full-grown young by 1 6 July 1974.
