34 AVIFAUNA COLUMBIANA. 



November, and found in all localities. Many individuals nest in the 

 parks in the city, as those about the White House and the Smithson- 

 ian Institution. In the fall, the berries of the sour gum (N'yssa multi- 

 flora) and poke (Phytolacca decandra) are their favorite food. Two or 

 three broods are reared each season. The nest, constructed largely of 

 mud, is placed usually upon the bough of a tree; the eggs are 4-Gin 

 number, uniform greenish-blue. [1]

ber. It is a shy and retiring species, frequenting thick woods and 

 tangled undergrowth, sueh as the laurel brakes along Hock Creek and 

 elsewhere. The nest, placed in a bush or sapling, differs from thai, of 

 the Robin in having no mud in its composition ; the eggs are similar, 

 but smaller. [0] 



3. (45.) Turdus ixxscescensSUph. Tawny Thkush ; Wilson's Thrush. 



A spring and autumn visitant ; rather uncommon, being the rarest of 

 the Thrushes. It does not ordinarily arrive until the first week in May ; 

 itrenminsbut a short time, and returns early in thefall. While with us it is 

 a shy aud solitary species, frequenting high open woods, but keeping- 

 near the ground. [7] 



4. (44.) Turdus unalascas nanus {Ami.) Coues. (T. pallasi of the original edition.) 



Eastern Hermit Thrush. 



A spring and autumn visitant ; does not breed here. It arrives much 

 the earliest of all the Trashes, usually the third week in March; imme- 

 diately becomes abundant, and is found until May. In the fall it re- 

 turns the first week in October, and remains until the third or fourth 

 week of that month — sometimes into November. Frequents chiefly 

 open woods. [10] 



5. (47.) Turdus ustulatus aliciae {Bel.) Cones. (T. aliciw of the original edition.) 

 A spring and autumn migrant ; doesnot breed here. Itis apparently 



as abundant as the Olive-back, more so than the Tawny ; it is found in 

 the same localities that the Olive-back frequents, and its times of ar- 

 rival and departure are about the same. It is perhaps fonder of swampy
