The Singing of Birds. E. P.Bicknell. 
The Crow Blackbirds. 
The Grackles are unaccountably erratic in their visitation to 
my neighborhood, and my notes on their vocalization are meagre 
and unsatisfactory. 
It may be said, however, speaking of the Crow Blackbirds 
broadly, without distinction between the Purple and the Bronzed 
varieties, that they are to be numbered with the birds which have 
their voice in the autumn. I have heard their squeaky song-notes 
in October, as late as the 23d. Auk, 2, July, 1885. p. .
