April 14, 1894 (E. M. Kindle) and Bloomington, April 10, 1903 (W. L. M.). 

 It is claimed that the more usual and expected occurrence would be the 

 arrival of this species at about the time of arrival of Wilson's and the 

 Olive-backed Thrushes. Further observation and especially collection of 

 specimens is needed to settle the question. The Gray-cheeked Thrush is 

 only rarely recorded as late as early October, as are also the Veery and 

 Swainson's Thi-ushes. But a specimen is recorded in the catalogue of 

 the Indiana University Museum, taken by David Starr Jordan, November 

 1, 1875, at Indianapolis. 



MIGRATION RECORD. 



212. [758a] Hylocichla ustulatus swainsonii (CaJo.). Olive-backed Thrush. 



Rather rare migrant. April 28 to May 19. September 1 to October 2. 

 C. H. BoUmann considered this species an abundant migrant in 1885. 

 At present only a few are seen each year. 



Most of the individuals departed May 17, 1885 (C. H. B.). Perhaps 

 the reduction in numbers of all the less hardy, wood-loving thrushes, in 

 recent years is due to the cutting away of timber in this region. There 

 are very few of those cool, dark, virgin forests, which are said to be the 

 favorite haunts of our wood thrushes, remaining in this region at present.
