378 MICHIGAN SURVEY, 1908. 



Migration: August 5 to September 12. 



On August 5 several Grinnell's Water Thrushes were seen at the edge 

 of Siskowit Lake (V, 9). They frequented the borders of the lake, secret- 

 ing themselves in the dense masses of fallen tree tops and rubbish. They 

 were afterwards seen running along on the bare rocks and sand, at a 

 distance being similar in their actions to the Spotted Sandpiper, as both 

 birds run in about the same manner with the accompanying tipping up 

 and down motions. These Water Thrushes could be as truly called "tip 

 ups" as the Sandpiper and were often found standing on a rock or 

 log tipping up and down and wig-wagging the tail. It was occasionally 

 found on the Lake Superior shore near camp, but was nowhere as com- 

 mon as on the inland lakes or streams. At Washington Harbor they 

 were found along the road, in the dense balsam forest and along the 

 river. During rainy days, especially, the Water Thrushes were quite 

 common along the road, more particularly in the damp places where 

 the alders thrived. Usually the birds were in pairs and were very shy. 

 About -the only way specimens could be procured was to call the birds 

 near by sucking or kissing the hand to make a noise resembling that of 

 a young bird in distress. This seldom failed to bring a pair or two of 

 excited birds within a few feet. As soon as the deception was discovered 

 they were quick to seek the protection of the long grass on the banks 

 of the stream or of a nearby rubbish heap. 



This bird probably breeds on the island, although nothing definite 

 was determined. While at Washington Harbor earlier in the season 

 I shot a young Water Thrush unable to fly, but could not find it among 

 the dense underbrush and ground hemlock which covered the ground. 

 An adult with three or four younig was seen with it, but it was too dark 

 under the thick balsams to see the color of the breast, or determine in 

 and other way whether it was Grinnell's or the Small-billed Water 

 Thrush. 



95. Geothlypis agilis (678). Connecticut Warbler. 



Eange: Eastern North America, breeding north of the United States 

 (Manitoba, Ontario). Northern South America in winter. 



Stations : Washingi:on Harbor, clearing at edge of forest, I, '04. 



Migration : September 12. 



Several Connecticut ^A'arblers Avere seen during the large wave of 

 September 12. They were found singly in the damp alder thickets along 

 the road. In actions they reminded one of the Water Thrush, running 

 along the fallen logs and keeping out of sight as much as possible. 



96. Geothlypis pMlad-elpliia (679). Mourning Warbler. 



Range : Eastern North America to the Plains, breeding from the 

 mountainous portions of Pennsylvania, New England, New York, and 

 northern Michigan northward. Central America and northern South 

 America in winter. Accidental in Greenland. 



Stations: Rock Harbor, burned area of rock ridge clearings, II, 3j 

 Shore of Benson Lake, II, 1. 



Breeding: July 11, j'oung seen. 



An adult female Mourning Warbler was seen near Benson Lake July 

 11, and near the outlet into Benson Brook an immature bird was seen 

 on the same day.
