came to us from the sky the weird laughter-like 

 cry of rails, the shrill confused whistling of a great 

 flock of whistling or tree duck; and, most frequent 

 of all, the beautiful wild trisyllabic alarm cry of 

 the upland plover. 



Of this bird, the last on my list for this chapter, 

 I must write at greater length; in the first place, for

 wild musical cry to fly but twenty or thirty yards 

 away and drop down again, to stand in a startled
