12. At Emporia, Kans. 5 the first was noticed October 6, and at Gaines- 

 ville, Tex., October 11. 



645 a. Helminthophila ruficapiila gutturalis Ridgw. [85, part.] Calaveras 

 Warbler. 



The western United States, from the Eocky Mountains to the Pa- 

 cific, is the habitat assigned to this sub-species by the A. O. U. Check 

 List. Its known range has been extended lately by Mr. William Lloyd, 

 who took it in Concho County, Tex., where it is an abundant fall mi- 

 grant. The specimens were identified by Mr. Eidgway. 



646, Helminthophila celata. (Say). [86.] Orange-crowned Warbler. 



The Orange-crowned Warbler breeds north of the United States and 

 winters, in the South Atlantic and Gulf States and in eastern Mexico. 

 It is not a very noticeable Warbler, but seems to occur abundantly at 

 several points in our district. It has been found occasionally iu large 

 numbers in northwestern Minnesota and Manitoba. Eecently Mr. 

 Lloyd has reported it as an abundant fall migrant in western Texas, 

 and Colonel Goss says it is a common migrant in Kansas. Mr. Brown 

 found it the most abundant Warbler in spring migration at Boerne, 

 Tex. In the valley of the lower Eio Grande in Texas it is rather com- 

 mon during the colder months (Merrill). In the spring of 1884 it ar- 

 rived at latitude 37° April 19, and was still present May 1. All the 

 dates given for the country between latitude 39° and latitude 44° were 

 in the few days from May 8 to 12. It would seem then that the spe- 

 cies, after pausing or proceeding slowly, accelerated its pace on those 

 four days, which were great days for movements, among Warblers all 

 over the Mississippi Valley. 



In the spring of 1885 the records of the migration of the Orange- 

 crowned Warbler were very regular. It first appeared at San Angelo, 

 Tex., April 2; at Gainesville, Tex., April 17 j Saint Louis, Mo., April 22; 

 Emporia, Kans., April 25; Paris, 111., May 3; Des Moines, Iowa, May 

 2; Lanesboro, Minn., May 4; New Eichmond, Wis., May 13. None 

 were seen at Des Moines, Iowa, after May 12, nor at Lanesboro, Minn., 

 later than May 25. 



The breeding range of the Orange crowned Warbler extends much 

 farther south in the West than in the Mississippi Valley. Hence it is 

 not surprising that in fall migration it appears at San Angelo, Tex., 

 nearly three weeks before it reaches Saint Louis. 



In the fall of 1885 the arrival of the first at San Angelo, Tex., Avas 

 noted September 4; while at Saint Louis, Mo., the first came Septem- 

 ber 21. The species was abundant at Saint Louis, October 10, and the 

 bulk was still present October 17. At Lanesboro, Minn., the last was 

 seen October 2. 



At Warrensburg, in western Missouri, it is an abundant spring mi- 

 grant, being common from the latter part of April till the middle of 

 May (Scott, Bull. Nutt. Ornith. Club, Vol. IV, 1879, p. 141).
