Woop—MersHon Expeprrion, CHArity ISLANDS. 93 
in nearly perfect spring plumage. These were the only adult birds 
seen. On August 6, a flock of six was seen on Rattlesnake Point. 
These were young birds and so fearless that we could walk by 
them at a distance of fifteen feet without frightening them. The 
light-house keepers said that the species was common in May and 
that some were seen as late as June 15. At Point Pelee, Ontario, 
the earliest record given (Taverner, 1907), is August 24. The 
turnstone is a regular migrant along the shores of the Great 
Lakes, rarely going inland. There is no record for Ann Arbor. 
47. (816) Zenaidura macroura carolinensis. MouRNING Dove.— 
The mourning dove was a rare species on the island, being seen 
but once, August 19. This bird was no doubt a straggler. It is 
doubtful if it breeds on the island. 
48. (3381) Circus hudsonius. MarsH Hawk.—This species did 
not breed on the island, and was first noted on August 23, when 
an immature bird was seen sailing about over the east end. On 
August 258, and at various subsequent dates, a few others were 
seen. The only adult bird (male) was observed on October 8. The 
rarity of this species on the island is probably caused as much by 
the absence of mice and the small number of frogs, as to the small 
number of suitable nesting sites. 
49. (332) Accipiter velor. SHARP-SHINNED HAWk.—The sharp- 
shinned hawk was first seen on September 3, and, while seen at 
various times after this date it did not become very common at 
any time. The light-house keepers said that in the spring hawks 
were abundant and many of them are no doubt of this species. On 
the east side of the Bay, about twelve miles from the island, a 
hunter told the writer that small hawks were very abundant for 
several days in the spring, and that he once shot twenty-seven in a 
short time. He thought they were of this species. The last birds 
seen on the island were two that were observed on October 5. 
No adults were observed. 
\0. (333) Aeccipiter cooper. CoopER’s WAawk.—Cooper’s hawk 
Was seen but twice on the island, on September 6 and 20, These 
were immature birds. 
ol. (8387) Buteo borealis borealis. Rep-rattep WHawk.—This 
hawk was not seen on the island, but the light-house keepers said 
that it comes there in the spring. On October 12, the writer saw 
an adult bird soaring over the woods near Oak Point. 
\2. (802) Haliwetus leucocephalus leucocephalus. Bap BEAGLE. 
—This species breeds on the island, where there is one nest in an 
old Norway pine. This nest is mentioned by Arnold,* who says,
