BIRDS OF MARSHALL COUNTY 73 



26. A nest with four eggs was found June 2, 1915, and one with 

 two eggs and three cowbird eggs was seen June 8, 1915. A pair of 

 wood thrushes were seen feeding a fledgling cowbird on June 27, 

 1914. A brood of three young were following a pair about in the 

 cemetery June 30, 1914. 



194. Hylocichla fuscescens fuscescens. Wilson Thrush. A com- 

 mon spring migrant from May 2 to May 17. In the fall it was less 

 commonly noted, September 9 and 10, 1913, and September 5 and 7, 

 1914, being the only dates on which it was seen. 



195. Hylocichla alicice alicics. Grey-cheeked Thrush. Migrant 

 from May 3 to May 22. It is impossible to say how common it was 

 as it appeared at the same time as the olive-backed thrush and it 

 was impossible to distinguish the great majority of individuals seen. 

 It was not noted in the fall. 



196. Hylocichla ustulata szvainsoni. Olive backed Thrush. Mi- 

 grant from May 3 to May 24 and from September 5 to September 

 29. The remarks under the gray-cheeked thrush apply to this 

 species also. 



197. Hylocichla guttata pallasi. Hermit Thrush. A common 

 migrant from April 9 to April 29. In the fall it was noted only 

 twice, October 14, 1913, and October 24, 1914. A bird brought to 

 me by Hartley Vogt on April 15, 1913, was picked up dead. 



198. Planesticus migratorius migratoriiis. Robin. An abundant 

 summer resident from March 9 to November 12. It is also reported 

 as a rare winter resident. A flock of thirteen was reported on De- 

 cember 4, 1913. On February 15, 1915, two birds were reported 

 and I saw one on February 16. These birds apparently came north 

 with the bluebirds and pintails which appeared immediately on the 

 breaking up of the ice. A pair were noted carrying nesting mate- 

 rial on April 18, 1913. The writer failed to record many data on 

 the nesting period of this species as most of the nests were built high 

 up in the trees along the streets and in the parks. On one occasion 

 five occupied nests were counted in one block in Marshalltown. 

 Nests with eggs were found on May 30 and June 5, 1915, and one 

 nest containing young was examined June 9, 1915. 



199. Sialia sialis sialis. Bluebird. A common summer resident 

 from February 14 to November 1. The bluebirds came on Febru- 

 ary 14, 1915, following a thaw and freshet which took the ice out 

 of the river. Cold weather again set in but these birds remained 

 about feeding on sumac (Rhus glabra) berries. No more arrived, 

 however, until March 19. The first birds appeared on March 8, 

 1913, and March 4, 1914. Bluebirds had partly completed nests
