312 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



Besides their delightful song, which is not heard until about a week after the 

 arrival of the birds, and the common exclamations phew and whee, they also hiss 

 like a Robin, and occasionally chatter in conversational and questioning tones.

 Gray-cheeked Thrush.

There is a specimen of this bird in the collection of the Peabody Academy,

A typical specimen in my collection was taken at Magnolia on September 

 1 8th, 1877. It bore for many years the label of the Olive-backed Thrush, as
