MELOSPIZA PALUSTRIS I SWAMP SPARROW. 255

 it instinctively chooses as a screen from the danger of 

 notoriety. It seldom ventures so far from its retreat 

 that a hurried flight of a few seconds will not enable it 

 to regain the thicket, and no oftener climbs the bushes 

 to any considerable height from the ground. More-

 Minot to the " sweet, clear trill " of spring-time, and 

 warbling notes of the falling season. "I remember to 

 have seen one at evening," he adds, "in the eccentric 

 expression of his passion during the season of love,
