NEW BIRD RECORDS FOR DELAVAN, WISCONSIN. 



By N. Holuster. 



During a recent visit to Delavan, Wisconsin, I had the pleasure 

 of examining- a small collection of neatly prepared bird skins made 

 at that place during the past few years by Mr. Charles Besecker. 

 The collection was of special interest to me because I found in it 

 eight species not taken by myself during a long period of collect- 

 ing in the same vicinity. Mr. Besecker began to form his collec- 

 tion about the time my active work in this region terminated. Six 

 of these captures make new records for Walworth County and 

 all seem worthy of publication. The eight species in question are : 



Sterna caspia. Pallas. Caspian Tern. 

 A single adult female shot at Delavan Lake, September 19, 

 1904. First county record. 



Phalaropus fulicarius (Linn.). Red Phalarope. 

 A single specimen shot by W. Holland at Delavan Lake, 

 October 11, 1902. Sex marked female ( ?). First county record. 

 Cathartes aura septentrionalis (Wied). Turkey Vulture. 

 One specimen, a female, Delavan, September, 1903. Hereto- 

 fore all Walworth County records have been based upon birds 

 "seen." The species is very rare indeed in this county and this 

 is the first capture to my knowledge. 



Astur atricapillus (Wils.). American Goshawk. 

 A beautiful adult male from Delavan Lake, October 23, 1907. 

 First record for the county. 



Aluco pratincola (Bonap.). Barn Owl. 

 One male from Delavan, April, 1910. Another individual was 

 seen by Mr. Besecker later in the season. Not before recorded 

 from the county.
