here on the migration by the severe weather. May 28, 1909, a pair 

 was found nesting in company with Bank Swallows. 



Lanivireo solitarius. Blue-headed Vireo. — Although in Cook's 

 list (1893) the species is not mentioned from Ann Arbor, Covert 

 (1881) speaks of it as "A not common migrant," and since that 

 time but few records have been secured. Our earliest spring 

 record is May 2, 1905. On May 10, 1901, Wood and J. Ricks each 

 secured specimens. The species was again noted in 1903, on 

 May 10 and 30, while in 1906 three were recorded on May 4, and 

 on September 26 of the same year Wood secured a specimen at 

 Portage Lake. It was recorded on May 9 and 14, 1907, and May 6 

 and 7, 1909. On the latter date a fine male and female were noted. 

 Although occasionally observed in the fall, as on October 7, 1908, 

 and September 26 and October 17, 1909, most of our records are 

 for the spring migration and are confined to the first two weeks of 

 May. From the foregoing it can readily be seen that the species 

 apparently has not increased to any extent since 1881, and, although 

 a more or less regular migrant through here, is far from common at 

 any time. 



Dendroica tigrina. Cape May Warbler. — Our earliest record 

 of the taking of the species within the County is the female in the 

 Museum collection, taken in the fall of 1869 by W. Harrington. 

 It seems to be somewhat irregular in its occurrence here, for while 

 in some years it is fairly common, in others it is apparently entirely 

 absent. In 1907 the Cape May was far from common both in the 

 spring and fall, but in 1908 several were seen and taken between 

 May 15 and 18. In 1909, the species first made its appearance 

 on May 6, and remained until May 23. In the spring, males seem 

 to be the more numerous, while in the fall females and immature 

 birds outnumber the adult males three to one. During the fall of 

 1908, the species was remarkably abundant, first appearing on 

 September 9 and remaining until September 27, the majority be- 

 ing either females or immature birds. 



Dendroica cerulea. Cerulean Warbler. — Covert gave this 

 warbler, in 1881, as "A very common summer resident, breeds; 

 nesting in the tops of tall trees." Since that date we have found 

 them very irregular and local in their occurrence; some years none 

 at all being seen. In 1903, Wood found several nests, but the next
