Occasional Papers of the Museum of Zoology 3 



At the west end of Howe's Lake is a large tamarack swamp, 

 while a smaller one lies at the end of Cranberry Lake. 



Clearings occur along the railroad right of way. These have 

 been repeatedly burned over, and farms have been started 

 near the small stations of Onota, Deerton and Rock River. 

 One extensive clearing designated as Schafifer's clearing, a 

 rather recently made one extending from Onota almost to 

 Whitefish Lake, formed an important habitat for birds that 

 nest or feed in the open. It is thickly covered with grass, 

 which attracts such birds as the meadow lark, vesper sparrow 

 and blue bird. 



As would be expected of a region so diverse as to offer con- 

 ditions from cultivated farm lands to original forest, the bird 

 life was interesting and abundant both in numbers of species 

 and individuals. Inasmuch as the period of observation ex- 

 tended from ]\Iay 24 to July 27 both migrants and breeding 

 birds are recorded in the following list. 



List of Species. 



1. Gavia unnicr (Briinn.). Loon. — First recorded on May 

 2y on Howe's Lake. One adult was noted almost daily on 

 Whitefish Lake, where it was joined on July 23 by a young 

 bird. 



2. Lanis argcntatns Pontopp. Herring Gull. — ^The herring 

 gull is probably only a straggler from Lake Superior in this 

 region as it was only occasionally observed. It was first 

 recorded on May 25. 



3. Sterna hirundo Linn. Common Tern. — This tern has 

 been observed during the spring migration. (Shiras.) 



4. Mergus amcricanus Cass. Merganser. — This species is 

 not uncommon during the spring and fall migrations. 

 (Shiras.)
