BIRDS. 285 



them, as they were seen there many times very early in the morning, 

 sometimes two in one tree. We often saw the tracks in the beach 

 sand, where the birds had picked up fish which were always carried 

 away to trees (generally dead ones) and eaten. Under these trees 

 (of which w^e found several on the Point) the bones of fish were found 

 in large cjuantities. These eagles were very tame and cjuite often 

 allowed us to approach within a few rods. This was probably due 

 both to the fact that no one troubled them and because a number of 

 them w^ere young of the year. We did not notice eagles hunting any 

 of the ducks or other birds, nor did we see them mobbed by the jays 

 or crows, although the latter species was very common. On several 

 occasions we saw eagles coming across the bay from the direction of 

 Charity Island, where Arnold* found them breeding in 1902 and 1903. 



40. Falco sparverius. American sparrow hawk. — Michigan: 

 Abundant summer resident, and also an occasional winter resident 

 in southern Michigan, breeding in holes in trees throughout the state. 



Observed at Sand Point on August 15 and 18, and three times in 

 the sand country at Rush Lake after August 7. The species did not 

 breed on the Point, although there were many trees with suitable 

 cavities, and plenty of food in the way of small birds, grasshoppers 

 and mice. Three were seen on August 18 that were no doubt mi- 

 grants from across the bay, as they were near the end of the Point, 

 where most of the migrants were first seen. 



41. Pandion haliaetus carolinensis. American osprey. — Michi- 

 gan: Scarce summer resident: breeds about lakes throughout the 

 state. 



One was seen near the end of Sand Point on June 14, and one at 

 Rush Lake. August 5. These were the only ones observed. 



42. Otus asio. Screech owl. — Michigan: Common resident, 

 breeding in hollow trees throughout the state. 



Not observed in the sand country. Two were seen on August 8, 

 and others were heard several times afterward in the clay country near 

 Rush Lake. 



43. Bubo virginianus. Great horned owl. — Michigan: A com- 

 mon resident and breeds all over the state. 



Observed several times in the sand country and on Stony Island. 

 This species was not a rare breeder in the sand country, and was often 

 mobbed by the crows. A family of three young birds and one adult 

 was observed on July 17 and 18 on Stony Island, and a breeding 

 record for North Island is given by Arnold. t
