230. PoLIOPTILA CARULEA CAERULEA (Linnzeus). 
BLUE-GRAY GNATCATCHER. (751) 
A fairly common summer resident. Arrives about the middle of April; 
begins nest building by the first of May. The nest is one of the most beau- 
tiful. It is a small, deeply cup-shaped structure covered on the outside with 
small greenish or grayish lichens, and is usually placed on some nearly 
horizontal limb. 
Carroll County: April 23, 1884, first seen today in Deer Creek bottom 
below Camden; May 5, saw two pairs building their nests near Camden ; 
May 8, saw a pair building in a white oak near Springboro bridge west of 
Pittsburg. The nest was about 18 feet from the ground. It was about an 
inch deep inside and very nicely made. On the 10th, this nest was still 
unfinished but the birds were working industriously; May 17, I secured 
the two nests found on the 5th; each contained five fresh eggs. April 22, 
1885. first of the season seen. The species was common on the 26th. 
Vigo County: May 10, 1888, a male obtained at Sand Hill; April 14. 
noted. 
Monroe County: August 15, 1885, saw several and collected one in Smith’s 
woods near Bloomington. April 12, 1886, noted. 
291. HYLOCICHLA MUSTELINA (Gmelin). Woop THRUSH. (755) 
Not uncommon as a summer resident; frequenting deep woods. In all 
nature there is no sound more beautiful and stirring than the song of the 
Wood Thrush. The birds arrive from the south in the last days of April 
and their rich liquid notes may soon be heard in any deep woods you may 
visit. By the middle or twentieth of May their nests with the full comple- 
ment of eggs may be found. 
Carroll County: June 17, 1882, nest with three fresh eggs, incubation 
begun. May 3, 1883, quite common near Burlington. The Wood Thrush, 
with many other species, seems to have returned last night, a great wave of 
birds having arrived and today the woods are full of birds. 
The Wood Thrush is one of the victims of the Cowbird’s parasitic habits. 
On May 24, 1883, I found a nest with four Wood Thrush and three Cow- 
bird eggs, all nearly fresh. On May 28, I found three nests, one with four 
eggs just hatching, another with four nearly fresh. April 28, 1884, returned 
last night. Saw several in Stone’s woods near Burlington. After May 5, 
they were quite common. April 25, 1885, saw and heard three or four on the 
Joseph Trent farm in Carrollton Township,—the first of the season. 
Vigo County: May 6, 1886, one noted; noted again May 3 and 5. Quite 
common in Vigo as it also is in Monroe County. 
Monroe County: May 6, 1886, nest with full set of eggs near Bloomington. 
232. HyYLOCICHLA FUSCESCENS FUSCESCENS (Stephens). verry. (756) 
Rare spring and fall migrant. 
Carroll County: April 16, 1885, noted as especially common. 
Vigo County: May 3, 1888, three seen, one collected, at the Hunt farm 
three miles southeast of Terre Haute; 12th, a female collected near Terre 
Haute. May 14, 1890, a female at the Sand Hill. 
Monroe County: May 18, 1886, several seen near Bloomington.
