Abundant summer resident from about the last week, in April to 

 October 1, The Wood Robin, the name by which (he Wood Thrush 

 is best known in tnis region, is a common inhabitant of woods. It 

 especially delights to frequent bushes in woodland, near streams or 

 other watery places. The sweet, ringing, bell-like notes of this bird 

 are such that it justly ranks as one of our most entertaining songsters. 

 It builds a compact and rather large nest of mud, leaves and dried 

 grasses in trees and bushes, usually in low or damp woods. The eggs, 

 commonly four, are light greenish blue, and measure about one inch 

 long by three-fourths wide. The Wood Thrush feeds on numerous 

 forms of insect life, it devours large numbers of beetles, earth-worms, 

 crickets, flies, larva3, etc., and also, like the Common Robin, subsists 

 on various small fruits and berries.
