Recollections of the Passenger Pigeon in Captivity

their expressiveness was greatly enhanced by the bird's movements. With 

 the loud notes, as used in anger, he stood at full height, in his majestic way, 

 and impressed the enemy by his bold appearance; and sometimes each loud 

 keck was accompanied, quick as lightning, by a stroke of both wings, which 

 struck the enemy if he was ne^ir enough, and powerfully frightened him if

 notes were hard. The male, when courting, gave also a coo, which was musical, 

 but so weak and faint that in my early memoranda I put it down simply as 

 "the weak note;" and this little coo, sounding more like keeho, was usually 

 given after the clucking or kecking notes, as a subordinate appendage to

 both voice and movement, and distinguishable from him even when motion- 

 less by a characteristic shyness in her attitude, especially in the pose of her 

 head. So distinct was this difference between the sexes that, in looking at the
