90 MICHIGAN SURVEY, 1908. 



of young it contained four bluish white eggs densely and irregularly 

 variegated with brown. Out in the marsh a Bittern was flushed from 

 the grass, and near by a deserted nest containing a bad egg and the 

 bones of two young was found. This nest was only a depression in the 

 tangled mat of grass in which it was situated. 



Two Loons were seen on the Lake many times, and these two birds 

 were much 'tamer than Loons usually are, for they swam very close to 

 the bank where I was standing. As soon as they saw me one of them 

 gave a weird and rapid "ha! ha! ha!" and on being imitated it would 

 reply every time. .V Hooded Merganser, another fish-eating bird, was 

 also observed here. 



V. SISKOWIT BAY REGION. 



When I arrived heie in August the breeding season was practically 

 over. Many young birds could fly almost as well as the adults, and 

 families were roving about the forests. Sandpipers were probably mi- 

 grating then, and although many were seen here it cannot be said that 

 they bred. In two weeks other birds began to come from the north 

 in large flocks, so that most observations were on habits of birds during 

 migration. 



Another evidence that the breeding season was over was the decrease 

 in the amount of singing. This was first noticed on July 20, and in 

 the next few days some species were heard for the last time. The follow- 

 ing is a list of birds with the last date upon which they were heard 

 singing : Nashville Warbler, July 24 ; Myrtle Warbler and Olive-backed 

 Thrush, July 25; Wilson's Thrush, July 26; Magnolia Warbler, Black 

 and White Warbler and Redstart, Aug. 4; Winter Wren, Aug. 8. 



Although birds are more apt to be found in all kinds of conditions 

 during migration, yet many of them showed a preference for certain 

 localities, so the -localities in which the birds were seen will be given. 

 This station has been, subdivided into the following habitats : 



1. Siskowit Bay and Shore (Station V, 1). 



2. Trail to Siskowit Lake (Station V, 4). 



3. Siskowit Lake (Station V, 6 and vicinity). 



4. Burning West of Outlet to Siskowit Lake (Station Y, vicinitv 

 of 9). - 



5. Long and Menagerie Islands (Station V, 10). 



1. Siskowit Bay and Shore (Station V, 1). 



The conditions at this place were about the same as those at Rock 

 Harbor, and almost the same species of birds were seen. Those seen 

 here were: Herring Gull, Loon, Scaup Duck, Solitary Sandpiper, 

 Spotted Sandpiper, Kingfisher, Amei'ican Merganser and Osprey. 



I cannot say with any certainty how many of these birds bred in 

 this vicinity, but the Gull and Merganser did, as a female Merganser 

 with a flock of very small young was seen several times, and the Her- 

 ring Gulls bred on the Islands south of the bay. The Loon, Kingfisher 

 and Spotted Sandpiper were observed nearly every day. The Solitary 

 Sandpiper was seen only once, on August 16. 



On August 8 four young Gulls were obtained from a fisherman, and
