mention that eggs have been taken at Charles City. 
172. Lanius borealis (Vieill.) Northern Shrike. <A toler- 
ably common winter resident, arriving in October’ or early 
November, and remaining into April. Mrs. Tuttle records 
it at Osage on October 24, 1914. I have records at Charles 
City for April 18, 1915, and April 23, 1917. The last is the 
latest date I have been able to secure. ; 
173. Lanius ludovicianus migrans (Palmer.) M igrant 
Shrike. A common summer resident, nesting in various parts 
of the county. Arrives in very late March or early April; 
nests about the first week of May, raising two broods. It is 
not uncommon to see a family of six or seven of these birds 
perched on a telegraph wire or a fence. They seem particu- 
larly common east of Charles City. 
174. Vireosylva olivacea (Linn.) Red-eyed Vireo. The 
Red-eyed Vireo is a common summer resident, arriving in 
early May and remaining until October. Eggs are laid in 
the first or second week of June. This species is the com- 
monest of the Vireos of Floyd County. 
175. Vireosylva philadelphica (Cass.) Philadelphia Vireo. 
A rare migrant. Recorded at Willow Pond on April 27, 1917, 
by Howard Clarke Brown. 
176. Vireosylva gilva gilva (Vieill.) Warbling Vireo. A 
common summer resident, ranking second to the Red-eyed 
Vireo. Arrives May 6 to 20; remains until early September. 
177. Lanivireo flavifrons (Vieill.) Yellow-throated Vireo. 
A tolerably common migrant; probably does not nest either 
in Floyd or adjoining counties. Passes north in late May. 
178. Lanivireo solitarius solitarius (Wils.) Blue-headed 
Vireo. A rare migrant. Howard Clarke Brown and Mrs. 
F. May Tuttle saw it near Osage on March 29, 1917. I have 
a record, for Willow Pond, on September 18, 1920. 
179. Vireo griseus griseus (Bodd.) White-eyed Vireo. 
The White-eyed Vireo is a common migrant, perhaps a 
summer resident. Arrival dates range from April 21 to May 
20, with May 12 to 15 as the average. 
180. Mniotilta varia (Linn.) Black and White Warbler.
