151. Vircosylva gilva gilva. Warbling Vireo. A common sum- 

 mer resident from May 3 to September 18. It was found com- 

 monly about the town as well as in the timber. A complete nest 

 was found June 28, 1915, at Mormons Ridge, but no eggs were 

 found in it. All through June and July of 1914 two pair frequented 

 a little patch of hazel and scrub oak, but the nests were never found, 

 although the writer searched many times. In July one pair was 

 seen feeding young in this patch so it is certain that they bred there. 



152. Lanivirco flavifrons. Yellow-throated Vireo. An uncom- 

 mon migrant from May 3 to May 22 and August 28 to September 22. 

 It probably appeared more frequently than my notes show, espe- 

 cially in the fall. 



153. Lanivirco solitarius solitarius. Blue-headed Vireo. A tol- 

 erably common migrant from April 29 to May 22 and August 20 

 to September 24. The blue-headed vireo was never abundant but 

 was found regularly every season. Ten noted on September 18, 

 1914, was the greatest number ever found in one day. 



154. Vireo belli belli. Bell's Vireo. The only definite record I 

 have for this species is a single bird noted one morning on a busy 

 street in Marshalltown. It was feeding in a small tree near the 

 sidewalk and allowed me to approach within a few feet and watch it 

 as long as I chose. Others were seen and heard which were sup- 

 posed to be this species, but identification was not positive. This 

 bird is most certainly more abundant than my records show. 



155. Mniotilfa varia. Black and White Warbler. The black 

 and white warbler is a common migrant from April 29 to May 22 

 and from August 21 to September 18. It was most commonly noted 

 in the spring migrations, probably because of the greater ease with 

 which small birds can be detected at that season. 



156. Vermivora chrysoptera. Golden - winged Warbler. The 

 golden-winged warbler was a rare migrant both spring and fall. 

 One was taken May 24, 1913, in a large patch of hawthorns. A 

 second bird was seen on three successive days (May 11, 12 and 13, 

 1914) about a small spring in the Marshalltown cemetery (Wilson 

 Bui., Vol. XXVI, p. 152, Sept., 1914). The third was a bird taken 

 September 7, 1914. 



157. Vennivora rubricapilla rubricapilla. Nashville \\'arbler. A 

 common spring migrant from ]\Iay 3 to May 17. In the fall it ap- 

 peared only in 1913. Beginning September 20, a greater or less 

 number could be found regularly in a little willow thicket back of 

 the Marshalltown cemeterv. Thev remained here until October 14.
