Lake Maxinkuckee, Physical and Biological Survey 567 



On one occasion in early autumn in a woods in Wisconsin the 

 old waxwings were observed feeding the berries of the "pigeon 

 oak" or white berried dogwood, Cornus femina, to their well- 

 grown and feathered young which were perched on a bough in 

 a row. 



137. WHITE-RUMPED SHRIKE 



LANIUS LUDOVICIANUS EXCUBITORIDES Swainson 



Summer resident, possibly a permanent resident, though we 

 have never observed it in this vicinity in winter. It frequents old 

 hedges and fencerows along public highways. We have noted 

 it October 3 and November'!!, 1900; March 24, 1901; and August 

 9, 1906. It was most often observed along the roads northwest of 

 the lake toward Yellow River. 



138. RED-EYED VIREO 



VIREOSYLVA OLIVACEA (Linnaeus) 



A not very common summer resident. Noted as common July 

 to September, and on October 4, 1899; July 17 and 19, and Sep- 

 tember 18, 1900 ; July 3, 1904 ; August 29 and Sept. 6, 1906 ; Au- 

 gust 4 and September 12 and 22, 1907; and September 14, 1913. 

 Probably more common than these few records would indicate. 



139. WARBLING VIREO 



VIREOSYLVA GILVA (Vieillot) 



Common summer resident ; its sweet liquid warble heard nearly 

 every day of summer from the leafy tree-tops. Noted on August 

 4, 1899. In 1900 it was common on various dates in July. In 

 1901 it was first heard April 27 on Long Point and on almost every 

 day thereafter. 



June 19 and 20, 1902, two or three pairs seen on Long Point 

 warbling merrily. On July 1 a pair was seen attacking a robin 

 that was sitting on her nest in a tree just in front of the Chad wick 

 hotel. The robin flew from the nest and out after them, with 

 feathers ruffled and evidently very angry. She drove them into 

 another tree some 20 feet away, then returned to her tree, when 

 one of the vireos followed and renewed the attack only to be 

 driven away again. The vireos would always retreat when the 

 robin got after them. They would attack the robin only when she 

 was quiet or when flying away from the vireos. Why they at- 

 tacked the robin was not evident; perhaps their own nest was 

 near by. 



In 1906 this species was noted at various times between July
