because I sought for it on the ground instead of in tlie 

 shrubbery. Later I found the same pair, as I supposed, 

 with their young within a few yards of this hazel thicket, 

 shot one of the juveniles in spotted plumage and sent it to 

 the Smithsonian Institute (No. 85,623 of that collection). I 

 saw both parents frequently during the month of July and 

 observed that they were gray or pallid. I was often within 

 a few yards of them, but heard no complaint or note of any 

 kind from them, nor am I certain that I have heard this 

 thrush utter a call note. On a solitary occasion a male that 

 was within a few yards of me expressed its displeasure at 

 my presence and gaze by giving several squalls which 

 resembled the complaining cries of Pipilo cJilorurus, after 

 which its two or more companions, that had been singing, 

 w^ere silent. 



Its song was first heard in the spring of 1889, by J. Clar- 

 ence Sperry, on May 12. The wonderful song of this bird 

 I know to be much superior to the song of T. miistelinus, T. 

 fnficescens, T. iistulatus and T, u. swainsonii. I never shot 

 one of these sweet songsters without pangs of regret. While 

 the songs of one individual may differ from those of another, 

 the tone or voice of all is much alike and may be readily 

 distinguished from those of T. iistulatus and T. u. swainsonii. 

 The following examples, which I copied as they were ut- 

 tered, will give some idea of its songs, though it is impossi- 

 ble to represent them in all their wild beauty on paper. 

 Some songs had irregular intervals and could not be cop- 

 ied.

In the third group of notes, the third and fourth notes 

 are in reality but one connected note, the latter portion of 

 which is, in a measure, an echo of the third.
