earlier in the season, as they now uttered short syllables sounding 

 like put, put, put, repeated rapidly, that of the males being harsh,

Fall. — Stuart T. Danforth (1925), who made some studies of a 

 breeding colony of stilts in Porto Rico, thus describes their departure 

 in the fall : 



By the latter part of June the adults had begun to flock again, and by the 

 middle of September all the stilts at the lagoon (155 by actual count) had 

 farmed one compact flock. This count was made on September 17. By 

 September 20 only about 50 were left; on September 23 there were 20; on 

 September 27 and September 30, 16 ; on October 7, 5. After that none were 

 seen.

 (Mazatlan and Escuinapa) ; Tamaulipas (Matamoras) ; Texas

 March 27, Daggett, April 10, Escondido, April 13, Stockton, April 

 13, Santa Barbara, April 14, and Fort Crook, April 19, Oregon, 

 Narrows, April 8, and Malheur Lake, April 17 ; Arizona, Palo Verde,
