Saint Louis a pair was observed April 6. From April 6 to April 17 

 these Warblers were conspicuous songsters. May 1 they were almost 

 silent. 



In the fall of 1885, at Saint Louis, they had all left their summer 

 stands by October 7, and none were seen later than October 11. 



666. Dendroica chrysoparia Scl. & Salv. [106.] Golden- cheeked Warbler. 



A tropical and subtropical species, ranging from central Texas to 

 Guatemala. The first known specimen from the United States was 

 killed near San Antonio, Tex., about 1864, by Mr. Dresser. In April, 

 1878, it was taken in Bosque County, Tex., by Mr. G. H. Kagsdale 

 (Bull. Nutt. Ornithological Club, Yol. IV, 1879, p. 60). During the 

 same month (April, 1878) Mr. W. H. Werner found it to be a tolerably 

 common Warbler in parts of Comal County, where four nests were dis- 

 covered in May (Ibid., pp. 77-79). In March, 1880, Mr. K C. Brown 

 captured seven specimens at Boerne, Kendall County, where the spe- 

 cies was first seen March 12 (Ibid., Yol. VII, 1882, pp. 36, 37); and in the 

 spring of 1883 he secured three more in the same locality (The Auk, 

 Vol. I, 1881, p. 121). Becently Mr. Lloyd, in his list of the birds of 

 Tom Green and Concho Counties, Tex., says of it: "One was shot in 

 a hackberry in April, 1887. Its stomach contained winged ants." (The 

 Auk, Yol. IV, 1887, p. 296.) 



667. Dendroica virens (Gmel.). [107.] Black-throated Green TTarbler. 



Breeds from northern Illinois northward, and leaves the United 

 States entirely in winter. In southeastern Texas it is abundant during the 

 migrations (Nehrling). The first note for 1884 came from Saint Louis, 

 where it arrived April 26. May 1 it was noted at Danville, 111. By 

 May 7 it had reached Minneapolis, Minn., and May 10 it was observed at 

 West De Pere, Wis. In the West it extends to the eastern boundaries 

 of Nebraska, Kansas, Indian Territory, and Texas, but was not re- 

 ported in 1884 from any of these States. 



In the spring of 1885 the records indicate a very rapid migration. 

 Seven days after the first came to Saint Louis, Mo., April 30, they had 

 appeared at Paris, 111.; Des Moines, Iowa; Lanesboro, Minn., and Elk 

 River, Minn. This would give an average rate of about 70 miles a day. 

 The bulk was present at Saint Louis, Mo., from May 5 until May 15, 

 when they suddenly disappeared. Some late records were sent in. It 

 was reported May 21 at San Antonio, Tex., and June 5 at Des Moines, 

 Iowa. 



In the fall of 1885 this Warbler was found migrating through San 

 Angelo, Tex., August 25; and Mr. Lloyd states that in Tom Green and 

 Concho Counties, Tex., it is a common fall migrant from August 1 to 

 September 20. This fact makes it almost certain that it will be found 

 to breed occasionally in the middle portion of the Rocky Mountains. 

 At Saint Louis, Mo., the first came September 17, and the last disap- 

 peared October 5.
