seen in town. They nidificate in May and raise two broods. 

 They feed exclusively on insects, and are strictly inoffensive. 

 During September, when about to migrate, become slightly gre- 

 garious, and generally disappear simultaneously." 



T. fuscescens, Steph. Wilson's Thrush. Tawny Thrush. Veery. 



Uniform tawny above; breast and throat washed with brown- 

 ish or pinkish yellow, and marked with small, indistinct, brownish 

 spots. Length, 7| inches ; tail, S^ inches. 



"Arrives about May 1st, occasionally earlier, and remains dur- 

 ing the summer. Abundant Frequents small trees and bushes, 

 and unlike the following, passes but little of its time upon the 

 ground. Builds a neat nest on or very near the ground, the eggs 

 being laid during the third week in May. Appears less abund- 

 ant late in the summer, and during September. This is on 

 account of their remaining more in woodlands and tangled 

 thickets than when on their first arrival ; they are abundant in 

 the open country. They have generally left by October 15th." 



T. aonalaschkse pallassii, Cab. Hermit Thrush. 



Olive brown above, becoming rufous on rump and tail ; breast 

 with nufberous, rather distinct, dusky spots ; a whitish ring 

 around eyes. Length, 7 inches ; tail, 2h inches. 



" During the month of May, 1859, and in each successive 

 spring, this interesting bird has appeared abundantly in the 

 State, nor has it, as its name would seem to associate, sought 

 only the most secluded localities, but has hopped fearlessly and 

 familiarly about, searching for insects and spiders among the 

 dead leaves, on which insects it exclusively feeds. As it remains 

 during the summer, it undoubtedly breeds with us, but the 

 author has as yet found no nests. During the past summer it 

 has been much less abundant. Although a magnificent singer, 

 the author has heard nothing but a weak chirp issue from its 

 throat, and that seems to be but seldom uttered." — [C. C. A.]

 Thrush. 



Uniform olive above ; breast and throat thickly marked with 

 large, dusky, olive spots ; breast and sides of head strongly buffy 

 tinted ; a conspicuous buffy orbital ring. Length, 7^ inches ; 

 tail, 3 inches.
