Mass. 
Cyanocitta cristata. 
Either unusually scarce or very silent and retiring. On 
April 30th a pair appeared about the cabin at about 7 a. in. , 
one of them breaking some dead twigs off a birch and flying 
with them to the crest of the hill. Next day I found the be-* 
ginning of a Blue Jay's nest in a small pine near the cabin! 
Mass. Barking like a Cooper's Hawk. 
While at Ball's Hill this afternoon I heard the barking 
cry of a Cooper's Hawk given several times in succession very 
near me. As I had never before heard this call in autumn I 
went at once to the spot and found - a Blue Jay. Although he 
would not say anything further I have no doubt whatever that 
he was the author of the sound. It was an absolutely perfect 
imitation.
