then dipping again tp the former level. The lowermost birds were 

 scarcely more than twenty feet from the ground. While the birds were 

 flying there was no singing and not much noise of any kind except that 

 made by the wings. It was evident that the birds had some definite 

 feeding ground selected, toward which they were hurrying in a straight 

 line. 



During the day no grackles could be found within four miles of Oberlin 

 in any direction. From the top of Spear Library I watched them come 

 in at evening. 



5:14. Five arrived from the north-east, flying high. 

 Three more heard in the trees of the roost. 

 Three arrived from the north-east, 

 One from the south settled in the roost. 

 One from the south settled in the roost. 

 Seven from the south settled in the roost. 

 Thirteen from the south settled in the roost. 



5:34 to 5:45. About 5000 arrived from the south, settled first in the 

 trees south of the building, then passed to the roost or to the trees west. 

 They came in companies of from 200 to 8oo, forming an almost continu-

 flying. 



5:50. 200 from the north and 150 from the south. During the next 

 five minutes about 100 arrived, the most from the south, but a few from 

 the east. 



5:58. 300 from the east-south-east. These and those of the previous 

 flight settled in the trees at once. 



There was much shifting about and flying to and from the roost until 

 6:00. One attempt to settle in the roost at 5:55 did not succeed. Proba- 

 bly less than half of all the birds which finally passed the night in the 

 roost were there at 6:00 ; the rest were scattered in the neighboring trees, 

 or restlessly flying about overhead. There was no singing, and little 

 scolding or sounding of the alarm note. 



6:02. Many returned to the roost from the north-east. 



6:03. Grand return from all directions. 



6:04. 150 arrived from the east. 



6:05. The birds well settled down in the foliage. 



6:07. Ten arrived from the south. 



6:10. 100 left the roost and flew to the trees some distance east on 

 North Pleasant street. Very few in sight in the trees. 



6:15. Practically all out of sight in the foliage. A few minutes later
