Note : This tract was canvassed in the early morning of 

 June 7th. On that date I heard three Olive-backed Thrushes 

 singing their weirdly beautiful songs. They had delayed 

 their northward migration journey unusually long and this was 

 a surprisingly late date to find them in this region. The sex 

 instincts of the males had impelled them to begin their love 

 songs, and there was no mistaking the note, for when once 

 heard and learned, it is never forgotten. I had heard faint 

 undertone snatches of their songs before, but never so en- 

 ticingly thrilling as on this morning. I was carried away in 

 memory to a summer spent in the woods of the Great North- 

 west, where among the firs and hemlocks and canvas tents, I 

 learned to know and to love the indescribable notes of the 

 Russet-back Thrush, a western variety of our Olive-back. I 

 could recall no difference in the songs of the two birds.
