avoiding the disconcerting occasional accident of stray scurries of 

 wind blowing up in under the plumage and disarranging it, a pro- 

 ceeding that it is easily seen would be uncomfortable in all cases, 

 and probably dangerous in many. 



200. ^HijlocicliJa miixteliiia.- — Wood Thrush. 



Common May 14, 1905, and one May 20, 1907. Not seen at other 

 times in spring. In fall we noted one vSeptember 13, 1905, and one 

 each day of September 1, 2, and 19 and 20, 1906. In 1907 but two 

 were seen September 29. The comparative rarity of this species is 

 rather peculiar. There is plenty of promising looking ground, but 

 it does not seem to be occupied. They likely migrate through in 

 considerable numbers, but we have never managed to be there the 

 right dates for this. The summer resident population of Wood 

 Thrushes on the Piont is evidently scanty. 



201. *HyIocichIa fiisccscens. — Wilson's Thrush. 



Fairly common on nearly all visits. May 11, 1905, two seen. May 

 21, 190C, several ; May 30- June 1. 1907, several each day. Usually 

 common through the first part of September. Last seen in 1905, 

 September 13, and one individual lingered the succeeding year as 

 late as the 20th. In 1907 Ave saw them almost daily froju August 

 24 to September 2, after which none were noted, though we remained 

 until the Gth. 



202. *tlylocic]iIa alickc. — Gray-cheeked Thrush. 



This does not appear to be quite as common a species as the next 

 on the Point. The two birds are, however, so much alike in ap- 

 pearance that it takes considerable attention and good opportunity 

 in the way of light to separate them. As it is not always practica- 

 ble to follow vip and scrutinize every thrush flushed in the woods 

 error in the records of these two species may at any time creep in. 

 A few of either species might easily escape notice among numbers 

 of the other. In spring we have positively identified this species 

 but once, May 30- June 1, 1907, when we estimated their numbers 

 at 25 and G respectively, and took specimens for full verification of 

 so late a date. This spring was, however, so abnormally late that 

 nothing in that line was any great surprise. May 21, 190G, we saw 

 several that we thought might be referable to this species, though 

 optical and other conditions precluded exact determination of this 

 point. September S, 1907, they put in their first appearance, becom- 

 ing common at once together with the Olive-back and with them 

 varying daily from none to common, irregularly to the date of our 

 departure the IGth. In 1906 they were not to be found among the 

 large numbers of Olive-backs present September 1-3, though we 

 looked carefully for them. On the return visit, September 15-21, we
