248 ANIMAL INTELLIGENCE 



3rd day. It does not wink when its eyes are touched, 

 and it is doubtful if it sees. 



On touching the bird it moves more than it did 

 yesterday, and now and then it opens its mouth a 

 little. 



On removing this If inch from its mate nestling, it 

 shifts lack again, guided chiefly by the warmth from 

 its fellow, I take it. 



It is placed on a perch about 1J inch wide. It does 

 not fall off, but clings to it. When my hand is held 

 within 1 inch, and below it, the bird puts down its 

 beak, touches my hand, and scrambles down into it. 



Every time I use the dog-whistle the bird moves its 

 head, which is a proof of hearing, for care is taken to 

 exclude the contact of the blast of air from the whistle. 



4:th day. It will, when placed on the perch, as 

 before, put its head down a great distance, but does 

 not move from its secure position; but it does creep 

 off into my hand under the same circumstances as 

 yesterday. 



6th day. It spreads out its wings when disturbed in 

 any way, or when in danger of falling off the roost. 



There is no evidence that the bird can distinguish 

 objects by the eyes. 



The winking reflex seems to be wholly wanting. 



A solution of quinine and one of sugar are used to 

 test taste, but with no clear results. When blown on, 

 etc., it utters the sounds peculiar to young pigeons. 



6th day. The bird can see at a distance of 1 foot 

 to-day, as evidenced by its movements when the hand 

 is passed before it. 



Holds its eyes open a good part of the time now. 



Under the application to the tongue of solutions of 

 sugar and of salt, there is some shaking of the head, 

 which is possibly evidence of taste. 



7th day. Clear evidence of vision at 2 feet.
