past eight o'clock when the last Robin is hushed. This sparrow has also 

 several forms of weak "tsipps''' or call notes. A common alarm note 

 is usually written " t'lick," almost a two-syllable exclamation. 



This bird is a terrestrial species, feeding on the ground as exclusively 

 as the Savannah sparrow, fully as recluse in its habits as that species, 

 except during the singing season when the male is constantly in evidence 

 fi5^ing in circles about the field, or seated on some prominent weed stalk. 

 When flushed it rises suddenly from beneath one's feet and darts hurriedly 

 away to dive and hide among the grass. 



The nest is concealed in the dense meadow, loosely woven of dry 

 grass and small weed stalks, lined with fibers, roots, fine grass and hair. 

 The eggs are 4 or 5 in number, white in ground color, spotted and speckled 

 with reddish brown; average size .73 by .54 inches.
