In none of the nests did we find bits of paper, at least where they could be seen. we had anticipated and commented on the prob- ability of their containing cotton , as cotton is grown in the vicinity, and the very first one found had tufts of cotton in the lining, as did some of the others. All were from a foot to two feet above the ground. These thrashers are distinctly smaller birds than Brownie and much lighter in hue. It may have been due to shadows cast, but they gave a definite impression of having dark patche/ on the throat, and dark ear coverts. They did not always sing from the low bushes; one was seen and heard singing from the top of a cottonwood. The song, to my ear, bears little resemblance to the full song except when both are heard at a distance. of T. redivivum. It is of about the same loudness as B's half to two quarter song, though less varied and contained no imitations. It lacks entirely the brilliancy and unexpected phrasing of T.r's full song, but it is "sweeter" than his full song. It contained no "words". Undeniably a beautiful song, somewhat of the order of that of the purple finch, though less varied. It is, perhaps, some most like one of Brownie's sub-songs (B has so many themes that it is impossible to say which one)--smoother and more rolling-- more conventional--less wild --less range--no mimicry--more vowels and fewer consonants --fewer musical phrases that one is able to "catch" and far less of the unexpected. Curiously, when heard at a distance of say 100 feet, I doubt if I would have thought it a much thrasher song, but at greater distances, when only the louder tones were heard, (which is how it was first heard) its resemblance to T.r. was sufficient to cause both of us to exclaim at once that there was the thrasher we were looking for. Dr. Reynolds, however, considers, I believe, that the nearby song resembles T.r's enough
