757a. Bicknell's Thrush : Turdus aliciae bicknelli (Ridgw.) 



Adult Upper parts rich olive ; under parts white, slightly tinged 

 on the breast with buff, shading into gray on the sides ; 

 throat, breast, and sides spotted with dark brown ; ring 

 round the eye dull white. Length 6.25 to 7.25. 



Breeding Range The mountainous regions of the Northeastern 

 States. 



The nest is placed in bushes or low trees, not far from the 

 ground, usually in damp woods. It is composed of leaves, grass, 

 moss, sticks, strips of bark, and lined with grass. The eggs are 

 bluish green (darker than those of the olive-backed thrush), finely 

 spotted with reddish brown. Size .87 x .63. 



This bird resembles closely the gray-cheeked thrush; it is 

 somewhat smaller and brighter in colour. 



758a. Olive-backed or Swainson's Thrush : Turdus 

 ustulatus swainsonii (Cab.) 



Adult Upper parts dusky olive ; under parts, breast, and throat 

 buff ; belly white ; sides gray with blackish spots except on 

 the belly ; eye ring and lores buff. Length 7. 17. 



Breeding Range In the higher mountains of Pennsylvania, and 

 from northern New England northward. Mr. Brewster 

 speaks of it breeding commonly on Mount Graylock in 

 western Massachusetts. 



The nest is placed in a bush or tree within ten feet of the 

 ground. It is made of leaves, grass, twigs, moss, and fine roots, 

 and is rather bulky. The eggs, 3 to 4 in number, are pale bluish 

 green with specks or spots of light reddish brown and dull lilac. 

 Size .93 x .68. 



The Olive-backed Thrush is an inhabitant of the secluded 

 woods, and during the breeding season, which commences about 

 the middle of June, they live almost exclusively in the regions 

 where coniferous trees abound.
