Study of the Avi-fauna of Lake Erie Islands. 171 



When all are at the roost there is a confused clatter of calls, 

 alarm notes, and scraps of song, finally they quiet down, often 

 during the night they become frightened and fly about the roost 

 calling to one another. Careful as they are many are killed 

 at night especially during the autumn. 



During the autumn the robins roam about the country 

 from one feeding ground to another, taking in turn wild cher- 

 ries, pokeberries, dogwood berries, and wild grapes. The 

 singing of the birds of the year, begun early in September, 

 now reaches its height, the robins may be seen chasing 

 one another through the woods calling loudly, now and then 

 hundreds burst into song, or frightened groups fly through 

 the woods as a hawk flies over. For a time at noon all is 

 quiet, then they begin as before and as sun set approaches 

 fly to roost. 



The roost is occupied until the leaves fall, when the robins 

 all leave at once. Last year this occurred on the 13t1i of 

 October.

Common on all visits to the Island, and migrating in small com- 

 panies during the most of August and into September. There 

 were no indications of such extensive nestings on the island as the 

 numbers found therg would Indicate to be the case.

None were found except in 1910. when there was one at the 

 Fishing Point swamp nearly every day after August 5, when the 

 first was seen. There were three there on August 11, two on the 

 22d, 29th and 31st. and eight on September 5. Conditions seemed 

 to be favorable for several nesting pairs, hut none such were 

 found.
