It can thus be seen that the parent birds fed their young 130 

 times in fifteen hours, or an average of once every seven min- 

 utes. Their food consisted of bugs and insects, and instead of 

 bringing but one they usually brought from two to four each 

 time. One of the birds, I suppose the male, would bring food 

 to the nest, and after feeding the young would fly to a near 

 branch and sing until the mate came with food. At one time 

 he sang forty-nine times. The female generally stood on the 

 edge of the nest for five or ten minutes after feeding the young.

These observations were made at the state hospital grounds, 

 Athens, Ohio. July 11, '08. The nest was made of grass and 

 mud, and was on a horizontal branch of an elm tree, about 

 eighteen feet from the ground. There were two young birds 

 about ready to fly ; often during the day they would climb up 

 and sit on the edge of the nest. The mother bird did all the 

 feeding of the young, and in nearly every case I found the 

 food to be an earthworm ; once in a while she would bring a 

 grub. 



I began my observations at 4 a. m. and watched fifteen 

 hours. The birds were fed as follows :
