276 WALLACE CRAIG 



sence of dish. But when I "pecked" in dish with pencil, it 

 showed keen attention and activity, came out of its nest and 

 to the dish and immediately drank, beginning the drinking 

 movements apparently before it quite reached the water. 



35^ day. — 8 P. M. (Electric light.) I put in same dish of 

 water. Bird immediately shows interest, comes out of nest, 

 walks near the w r ater, back and forth, but does not drink. I 

 then begin tapping in water with pencil. This excites the bird. 

 It makes a slight begging movement toward the fingers holding 

 the pencil. Then it makes a slight drinking movement, outside 

 the dish. But though I tap long with pencil, and move dish 

 about, it does not drink. Then I drop seeds into dish. It grad- 

 ually concentrates its attention, finally runs at a dash into the 

 dish and puts bill down beyond the dish and tries to drink there. 

 Failing there, it immediately puts bill into dish and drinks a 

 long, deep draft. What caused it thus suddenly to find the 

 water? It may have been wet feet; or it may have been sight 

 (reflection of the electric light?). 



36th day. — 2 .-30 P. M. I put in same dish of water. This time 

 dove needs no tapping with pencil, no dropping of seeds. It 

 soon concentrates attention, goes to dish, stops a moment, walks 

 into dish and tries to drink from beyond it. Failing in that, 

 it immediately puts bill into dish and drinks. 



37^ day. — 10 A. M. Same dish put in. Bird recognizes it 

 at once, walks into the dish, puts bill down beyond dish and 

 tries to drink; seems disappointed and tries thus several times. 

 Then walks beyond dish on floor, walks round to original side 

 of dish, stops, and after a little hesitation and apparent 

 "thought," puts bill down toward water, then into water, 

 and drinks. 



8:20 P. M. As I poured water into dish, out of sight of bird, 

 it showed indubitably that it recognized the sound, trying to 

 get out of cage toward source of sound, making slight move- 

 ments which show thirst. On some previous days I have been 

 quite sure that it did not recognize the sound of dropping water. 

 I put dish in cage. Bird, in nest at other end of cage, reaches 

 out vaguely toward dish, then bends down and tries to drink I 

 This it repeats several times. It then comes down from edge 

 of nest, walks toward dish, tries to drink outside dish, steps 

 into dish, tries again without getting bill into water, soon steps
