BIRDS. 297 



latter date, young birds began to appear. When we called birds by 

 sucking the back of our hands, this species was nearly always the 

 first to appear. It was still on Sand Point when we left the field, 

 August 27. 



94. Mniotilta varia. Black and white warbler. — Michigan: Com- 

 mon migrant and summer resident: breeds throughout the state. 



Not observed commonls' in the sand region during the breeding 

 season, but abundant after August 1. It was a rare breeder on Sand 

 Point. A female that acted like a nesting bird was seen near the 

 edge of a thicket on June 22. Others were seen on Jul}' 3 and 4. We 

 first saw the young on July 18, when a family was seen at the edge 

 of a thicket, where they no doubt were raised. It was seen in small 

 flocks during the rest of July. From August 1 to 4 a migration wave 

 of warblers reached Sand Point, and this species became very com- 

 mon, a few being observed in every flock. At Rush Lake they were 

 not observed so commonly until August 10. They were still ver\' 

 common all over the sand region w'hen the party left the field, August 

 27. They were the most curious of the warblers, often coming with- 

 in a few feet of one when called by chirping. When feeding they 

 seemed to prefer the larger limbs and trunks of the trees and were 

 often found feeding on the trunks of the willow bushes at the edge of 

 the thickets, going over them like a nuthatch or chickadee, in whose 

 company they often fed. They w^re also often seen on the low jack 

 pines and in the oaks. 



95. Helminthophila chrysoptera. Golden-winged warbler. — 

 Michigan: Not uncommon summer resident, breeding throughout 

 the state with the exception of Isle Roy ale. 



Apparently a rare migrant in the sand region. The species was 

 only observed on Sand Point. The first one seen was on August 5, 

 when the water thrush was also first noted. Another was seen Aug- 

 ust 6. All of these were in the thick willow-poplar thickets at the 

 end of the Point. Four more were seen on August 7, in thick willows 

 at the edge of an open swamp. They were very shy and wild and 

 could be seen only by hiding and chirping softly. If this was done, 

 and one of these birds was within hearing, it would cautiously work 

 its way toward us but would disappear at the slightest movement. 

 The last one w^as seen August 14, and, although these habitats were 

 worked daily during our stay, no more were seen. 



96. Helminthophila nibricapilla. Nashville warbler. — Michigan: 

 Common migrant and summer resident, breeding north of latitude 

 44°. 



Apparently to be considered only as a migrant in the sand region: 

 seen at Sand Point and Rush Lake. It was first found on July 24
