Blue-bird. 
Black - bill 
Cuckoos 
singing at 
night 
Yellow - bill 
Cuckoo 
does not 
sing; at night 
was a singularly passionless union, in keeping with the 
birds' generally calm, phlegmatic demeanor. 
On reaching the Buttricks' I at once heard a 
Blue-bird warbling with peculiar fervor and frequency. It 
kept it up almost unceasingly until nearly dark and the people 
at the house told me that it had been singing thus during 
the entire day. 
Robins sang freely at sunset and after dark or 
rather after the moon rose. I heard Black-billed Cuckoos 
at frequent intervals far into the night. Usually the song 
was much abbreviated and sometimes only the wor- r-r-oo 
was given in a low dreamy tone as if the bird were calling 
in its sleep. I have nevey, so far as I can remember, heard 
any sound whaterer from the Yellow-billed Cuckoo at night. 
That I do not hear him here these warm, moon-lit evenings 
is fairly strong proof that he seldom if ever sings after 
dark for at least one pair haunt the trees about the house 
and a.re constantly to be heard during the day. j
