  Butcher-bird but I saw none. The note given
at this particular time was not unmusical but by no means
one of the Shrike's best - to my taste, at least. When
he was in the catalpa tree a number of birds alighted,
one after another within a few yards of him. A cock 
House Sparrow (apparently oblivious of danger) was quite ignored
but he drove from the tree in succession a Flicker, a 
Downy Woodpecker and three more Bronzed Grackles,
flying at them aggressively and chasing two (the Downy &
Flicker) several rods but not showing any indication of real
murderous intent. One and all of these birds behaved
towards him as they might towards any harmless bird
of similar size, evincing little fear of him and apparently not
suspecting his true character. After reaching
the Parkman's apple he sang for awhile in its top &
then dove down into the tangle of closely imbricated
Northern Shrike
