250 ANIMAL INTELLIGENCE 



When placed on the perch, it dings more firmly than 

 before, and in a different fashion in fact, more like a 

 mature pigeon. 



27th day. The bird is practically completely 

 feathered. 



34th day. This owl-pigeon is leading a compara- 

 tively independent existence, and is out of its nest most 

 of the time, and flying about the loft, though occa- 

 sionally fed by the parents, which are sitting on 

 another nest of eggs (two). 



Dragoon-Pigeon hatched out and fed by its Parents. 



This one will be named B, to distinguish it from 

 another, C. 



1st day. Eyes unopened. The loudest whistle pro- 

 duces no effect. The bird is evidently deaf. 



Blowing on it causes the bird to move. Putting its 

 beak to one's mouth, it opens the former. 



When placed on an elevated surface it does not creep 

 or fall off, though it moves its beak about, up, down, 

 etc. 



2nd day. Eesponds to the dog-whistle to-day. 



Eyes open, but usually kept closed. 



3rd day. Eyes more completely open, but lids are 

 usually held closed. 



5th day. Keeps its eyes open most of the time. 



It can now hold up its head pretty well, which is an 

 impossibility in all pigeons just after birth. 



6th day.ThQ eyes are kept open nearly all the 

 time, and the head held better in fact, well. 



7th day. Progressing, but as yet does not peck with 

 the beak at the approach of an intruder. 



9th day. Does snap with the beak to-day, but does 

 not peck. 



Wth day. Pecks to-day.
