Beside these, many other records have been made, giving breed- 

 ing dates which extend the season of residence for certain migrants, 

 and noting the occurrence in this region of several irregular and 

 rare visitors. 



Among the records of special interest may be mentioned the 

 l^reeding of the Fish Crow in the city, the breeding of the Prairie 

 Warbler, very late records for the Ruby-throated Hummingbird 

 and the Junco, and records for the Whistling Swan, Yellow- 

 crowned Night Heron, Black Rail. Crossbill, and Pine Siskin. 



The species listed below are those for which additional information 

 has been obtained since the last pubHcation of the records of the sur- 

 vey. In cases where migration dates have been extended, the season 

 of residence is given as now known ; reference to the last published 

 list will show the changes which have been made. Five species, 

 hitherto unrecorded, have been added : Blue-winged Teal, Whistling 

 Swan, Black Rail, Solitary Sand-piper, and Crossbill.
