294 BIRDS. 



mon summer resident, breeding all" over the state with the exception 

 of Isle Roy ale. 



Observed four times on Sand Point and once in the clay country at 

 Rush Lake. It is probably to be considered as a rare breeder in this 

 region, for during the breeding season it was observed only twice, on 

 June 26 and June 30 (Sand Point). An immature male in fall plumage 

 was seen on August 24 and another on August 25. These were 

 with flocks of warblers and were probably migrants. 



85. Progne subis. Purple martin. — Michigan: Common sum- 

 mer resident, breeding throughout the state with the exception of 

 Isle Roy ale. 



Common about the towns in the sand region (Bayport and Case- 

 ville), but only occasionally elsewhere. It apparently did not breed 

 on Sand Point, but several breeding pairs and nests were observed 

 at Bayport, on June 13. The nests were built on cornices of the 

 hotel and stores. We saw single pairs on August 2 and 5 flying over 

 the water along the north beach of Sand Point. There was a small 

 colony at Caseville, where we saw^ them several times, and they were 

 also occasionally seen about Rush Lake. 



86. Petrochelidon lunifrons. Cliff swallow. — Michigan: Com- 

 mon summer resident, breeding throughout the state. 



Several flocks observed on Sand Point, August 12, and a single 

 bird on Stony Island, July 16. The species occurred in the sand 

 region only as a migrant. The only record was secured on August 

 12, when early in the morning several flocks were seen near the end 

 of Sand Point. In company with barn and bank swallows, these 

 birds were slowly flying down the Point, feeding on the way. The 

 single bird seen on Stony Island was also with a flock of barn swal- 

 lows. 



87. Hirundo erythrogaster. Barn swallow. — Michigan: Abun- 

 dant summer resident, breeding throughout the state. 



A rare breeder, except about the towns, but a common migrant in 

 the sand region, and a common breeder in the clay countr}^ at Rush 

 Lake and on Stony Island. The only pair that nested on the Point 

 had a nest on top of a door on the west side of a fish house, and on 

 June 15 the five eggs w^ere nearly ready to hatch. A severe storm 

 washed this nest away on July 17, and for five days the old birds 

 flew about in distress. On July 22 we saw them carrying nesting 

 material into a large house on the shore nearby, and here they built 

 a second nest on a high rafter in the peak, where they raised a brood 

 of young which were still in the nest on August 4. On the latter 

 date, flock after flock of this species were coming from the west and 

 northwest across the bay from the direction of Point Lookout. These
