80 LAND-BIRDS. 



This last group is ranked as a subfamily, the others being 

 united by Dr. Coues as Sylvicolince, though Prof. Baird further 

 sets apart the Geothlypince. (For remarks on Icterince, see 

 10.) The Warblers are, no doubt, to many persons the most 

 charming of our birds. They are eminently peaceful, and pret- 

 tily colored, brightly, sometimes brilliantly. Musically, how- 

 ever, they are generally surpassed by the Thrushes, Vireos, and 

 Finches. They are insectivorous, migratory, and in some cases 

 gregarious, except in summer. Among their nests are some 

 of the neatest and prettiest specimens of bird-architecture. 

 The eggs are, for the most part, four or five, white, spotted 

 with brown and lilac.

b. The nest is usually built on or near the ground, in a 

 swamp or at least the neighborhood of water. The eggs of 

 each set are usually four, average .85 X .67 of an inch, though 

 variable in size, and in coloration closely resemble those of the 

 Golden-crowned " Thrush " ((7, 6).f A nest which I found 

 near Boston contained fresh eggs in the first week of June.
