food at the house. The conditions of the experiment, therefore, 
render it highly improbable that the hornbill was eating insects 
which it would normally reject, and its whole demeanor was quite

It is apparent that experts may draw very different conclusions 
from the same experimental data, a fact among many which points 
to the conclusion that the results of stomach examination are the 
only reliable criteria regarding bird food. 
Experiments in Asia. 
No experiments are more widely quoted than those performed by 
Frank Finn while Deputy Superintendent of the Indian Museum, 
Calcutta. Only those of Pocock are more extensive, and they were

Asiatic Society of Bengal, as follows:
