BIRDS OF MARSHALL COUNTY 65 



and remained until May 2,\ 'I'hc only summer records that I have 

 are of a single bird August 10. 1914. and a pair July 27, 1915. Only 

 scattered records were made during the fall as follows : September 

 18 and 19. 1913; September 17, 1914; October 8, 1913, and Novem- 

 ber 27, 1914. 



147. Lanius bor calls. Northern Shrike. The northern shrike 

 was seen only twice, once March 29, 1913, and the second time 

 ]\Iarch 30, 1914. Curiously enough both records were made in the 

 same clump of dead trees. On the first occasion my attention was 

 called to the bird by a rather pleasing but unfamiliar song. It is 

 probably a more common visitor than my records show since I did 

 not get out much in the winter into the open country. 



148. Lanius ludivicianus migrans. Migrant Shrike. A toler- 

 ably common summer resident from April 5 to November 13. While 

 never found in great numbers, the nest of this species was the most 

 easily located of any breeding species. A solitary hawthorne found 

 along a country road was almost certain to hold a nest. A nest 

 containing five nearly fledged young was found May 29, 1913 ; a fully 

 fledged family of four young was seen July 16, 1914; five nestlings 

 were seen on May 23, 1915; a nest with three eggs found June 4, 

 1915, contained six eggs on June 8. One found June 21, 1915, con- 

 tained five eggs and held five young on July 5 when visited. These 

 nestlings were about five days old at this time. 



149. Vireosylva olivacca. Red-eyed Vireo. Common summer 

 resident from May 10 to September 22. The red-eyed vireo shared 

 with the indigo bunting the honor of being the most persistent 

 songster through the long hot summer days. Plenty of vireos' nests 

 could be found after the leaves had fallen but the only occupied one 

 ever discovered was one on Mormons Ridge June 29, 1915. When 

 found the vireo was incubating three cowbird eggs. She subse- 

 quently left the nest and a close examination revealed the fact that 

 it was a double nest which contained one cowbird tgg in the bottom 

 chamber. Thus four cowbird eggs had been laid in this vireo nest. 



150. Vireosylva philadclphica. Philadelphia Vireo. A vireo 

 shot for a warbling vireo on September 7, 1914, proved, when exam- 

 ined carefully, to be a Philadelphia vireo. This and another bird, 

 September 18, 1914, are the only records I have for the county. Its 

 close resemblance to the warbling vireo makes it difficult to deter- 

 mine its exact status in the region. It must, however, be credited 

 as a rare migrant on the basis of the present data. This specimen 

 secured on September 7 was identified by H. C. Oberholser.
