THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 249 



If the bird is placed anywhere out of its nest, it 

 moves about in a restless way. 



Sth day. Evidence of vision at 4 feet. 



9th day. Can now see objects distant 6 feet. 



When the sides of the beak are touched, movements 

 follow, as if preparing to receive food. 



10th day. Objects now seem to be visible to the bird 

 at any part of its own compartment of the loft, i.e. at 

 9 to 10 feet. 



To-day, for the first time, is witnessed undoubted 

 defensive snapping, or pecking with the beak, when the 

 hand is brought near it, whether in its nest or on the 

 floor of the loft. 



Feathers are now grown out far enough to enable one 

 to judge of their colour. 



llth day. Growth of feathers and general growth 

 now considerable. 



The bird can now walk fairly well. 



12th day. An improvement in walking and feather- 

 ing noticeable since yesterday. 



13th day. When placed on the floor of the loft, 

 within a few inches of the nest, it attempts to return 

 to the nest through some slats that fenced it in. The 

 nest is on the loft floor, and is covered with sawdust 

 only now, though at first there was also a little straw. 



15th day. The bird can now get back to its nest 

 when 2 feet away, and also succeeds in pushing between 

 the slats. 



16th day. The parents have somewhat neglected the 

 feeding of their offspring to-day, as they are preparing 

 to sit again. 



17th day. Better fed to-day. When either parent 

 enters the little compartment in which the nest is, the 

 young one scrambles over a brick that surrounds the 

 nest to solicit food. 



19th day. The bird is now well-feathered.
