BIRDS. 283 



First seen on August 3 and again on August 17 at Sand Point. Ob- 

 served several times between Oak Point and Hat Point after August 

 22. The species was the first migrant wader seen. The bird seen 

 on August 3 was a fine adult female in breeding plumage; an old male 

 in the same plumage was seen on August 17, but the birds that came 

 later all seemed to be immature. A flock of about fifteen was seen 

 feeding on the mud in a recently dry pond on Oak Point, August 28, 

 the last day of our stay. 



30. Arenaria interpres morinella. Ruddy turnstone. — Michigan: 

 Rather common migrant along the shores of the Great Lakes. 



After August 20 (first record) this species was observed commonly 

 along the beach, although usually in small numbers and in company 

 with sanderling. semipalmated plovers or spotted sandpipers. The 

 only flock seen was on August 27, when five were seen at Oak Point. 



31. Colinus virginianus. Bob-white. — Michigan: Common resi- 

 dent; breeds throughout the state but not so commonly in the Upper 

 Peninsula. 



One was heard calling at the base of Sand Point on July 16, and 

 another in the clay country near Rush lake on July 19. This species 

 preferred the vicinity of cultivated fields and occurred in the sand 

 region only as a straggler. It was not uncommon on the farms about 

 Rush Lake. 



32. Bonasa umbellus. Ruffed grouse. — Michigan: Common resi- 

 dent and breeder as far north as latitude 44°. In northern Michigan 

 B. u. togata is the common form. 



The species was quite common in the wooded swamps and was often 

 seen in patches of blueberries in the burnings. In July and August, 

 berries with grasshoppers picked up in the same locahties formed a 

 good share of their food. The juneberry seemed to be a favorite 

 food, and a juvenile bird on July 10 had its crop full of these fruits. 

 We often saw^ bevies of old and young in the roads that crossed the 

 Point in all directions. An adult female and ten young were seen 

 at Sand Point on July 10, and a good sized covey near Oak Point on 

 August 25. 



33. Zenaidura macroura carolinensis. Mourning dove. — Michi- 

 gan: Common summer resident and an occasional winter resident, 

 especially in southern Michigan; breeds all over the state. 



This bird was only seen a few times in the sand country and once 

 on Stony Island, but was more common in the clay country. Only 

 one nest was found and that was in the hardwoods at the base of 

 Sand Point. 



34. Circus hudsonius. Marsh hawk. — Michigan: A common sum- 

 mer resident throughout the state, breeding locally on the ground in 

 marshes.
