The Savanna Sparrow Breeding in Detroit and Hamtramck Village, 

 Michigan. — One especial ornithological feature of the season 1907 was the 

 appearance of Savanna Sparrows {Passerculus sandwichensis savanna) 

 as summer residents on territory not previously occupied by them. Prior 

 to 1906 this sparrow was not kno\\Ti to breed in the county but that season 

 I located a small colony in the village of Grosse Pointe Farms and established 

 a positive breeding record by securing a young bird not yet able to fly well 

 (Auk, XXIV, p. 98). The grounds extending northerly from this colony 

 to the county line and southerly into the city of Detroit were carefully 

 explored \\ithout result, but in 1907 this sparrow was common in all suit- 

 able places throughout this entire territory. In late May, 1906, I spent 

 considerable time on some large commons in the eastern part of the city 

 and carefully noted all birds, but no Savannas were present. I was again 

 on this commons May 28, 1907, and found them all over it; six males in 

 song being counted while standing at one point. During the noon hour I 

 w"atched a female to her nest containing four slightly incubated eggs. 

 This was about fifty yards inside the city limits on P. C. 644. In June, 

 1906, I frequently walked the length of a strip of meadow bordering the 

 Detroit River in River Rouge Village and saw only Vesper Sparrows, but 

 June 3, 1907, six pairs of Savanna Sparrows were present and frequently 

 seen later; and thus it was with portions of Hamtramck, Springwells and 

 Ecorse Townships. The birds were also found in many places not visited 

 in 1906. July 30, 1907, I found this species common and in full song on 

 Section 6, Monguagon Twp.; the southernmost point I reached during 

 the summer. It is thus evident that the breeding range of this sparrow 

 in numbers was extended southward in 1907 — a phenomenon possibly 

 explained by the abnonnal weather conditions. I have no doubt that iso- 

 lated pairs frequently nested here in fonner years and were overlooked. 

 I have substantial proof of this in the possession of a set of five fresh eggs 

 taken by Mr. Herbert H. Spicer, May 28, 1902, in i Section 39, Hamtramck 

 Village. The territory, over which the Savanna Sparrow was a summer 

 resident in 1907, extended from the shore of Lake St. Clair and the Detroit 

 River inland about three miles, and from the north county line southerly 

 a distance of twenty-five miles to Section 6, Monguagon Twp., and probably 

 further. At a few points in Gratiot and Springwells Twps., Highland Park, 

 etc., the birds were noted from one to three miles further inland. — J. Claire
