108 BIRDS OF SWOPE PARK 



shaw r. Horned Larks are found sparingly in the Park, 

 though common enough in the prairie country near by. Oc- 

 casionally one nests on the golf courses. 



Bljue Jay, Cyanocitta cristata cristata (Linn) r. Blue Jays 

 are to be found in all parts of the Park at all times of the 

 year, though they are more numerous in the parts frequented 

 by human beings. 



Crow, Corvus brachjrhjnchos brack yrhynchos Brehm 

 r. There is never a day during which crows may not be seen 

 flying about over the Park, but they nest only in the more 

 secluded portions. 



Bobolink, Dolichonyx oryzivorus (Linn) tr. These 

 birds are all too uncommon with us, even during migration. 

 We would be glad to see more of them and be delighted with 

 their songs. My Park record includes only two male birds 

 that I saw and heard sing in a red haw tree in the northwest 

 corner of the Park, May 11, 1919. 



Cowbird, Molothrus ater ater (Boddaert) sr. Cowbirds 

 are all too common throughout the Park. Scarcely a nest of 

 vireo or warbler or bunting can be found that does not have 

 one or two Cowbird eggs in it. 



Red-winged Blackbird, Agelaius phoenicius phoenicius 

 (Linn) sr and occasional r. These birds are very numerous 

 during migration and sometimes great flocks are seen dur- 

 ing winter. Few, if any, nest in the Park. 



Thick-billed Red-wing, Agelaius phoenicius fortis, Ridg- 

 way wr. During the winter of 1917 thousands of these north- 

 western Red-wings spent part of the winter months in the 

 Park. This was unusual.
