THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 249 
If the bird is placed anywhere out of its nest, it 
moves about in a restless way. 
8th 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 pad 
at any part of its own compartment of the loft, 2.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. 
11th 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.
