200. * /////</</(///'/ muNh'Jimi. Wood Thrush. 



Common May 11. 190.">, and one May 2<>, p,K7. Not seen at other 

 times in spring. In fall we noted one 'September 1.",. I'.mr.. and one 

 each day of September 1, 2, and 1!) and 20, 1900. In 1007 but two 

 were seen September 20. 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. *Hj/1ocic1i1a fuscescens. Wilson's Thrush. 



Fairly common on nearly all visits. May 14, 1905, two seen. May 

 21, 1900, several; May 30-.Tune 1, 1007, several each day. Usually 

 common through the first part of September. Last seen in I !<>.",. 

 September 13, and one individual lingered the succeeding year as 

 late as the 20th. In 1007 we saw them almost daily fn>'n Aum:-t

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-
