1. Wood Thrush — hylocichla mustelina. Color, uniform deep blue, 

 resembling the eggs of the Robin, but smaller. The number laid is usually 

 four, and the average size is i. by .75. The nest is built in low trees or 

 bushes, and composed of leaves and grasses with a layer of mud; on this 

 there is a lining of vegetable fibres. The bird is found chiefly in low, 

 damp wood^ and in thickets. Breeds throughout every portion of United 

 States between the Mississippi River and the Atlantic, as far as Georgia 

 on the south and Massachusetts on the north. 



Habitat: United States east of Miss 



luth to Guatemala. 



2. Wilson's Thrush — hylocichla fuscescens. Bluish-green, unspot- 

 ted; four or five in number and average .87 by .62. The nest is usually 

 placed on the ground or near it at the foot of a bush or tussock. It is 

 composed of a mass of weeds, grasses, leaves and bark, lined with fine 

 roots and hair. The nest and eggs are not distinguishable with certainty 

 from those of the Hermit Thrush. The Wilson's or Tawny Thrush breeds 

 as far south as Pennsylvania and Ohio and as far west as Utah and occurs
