afternoons of August, as well as at all other times, the song of the Hermit 

 could be heard from his perch in the dead top of a tall beach or hemlock. 

 Migrants were seen up to the time I left.

 were seen during September. 



NOTES ON THE BIRDS OF mLV COUNTY, ARIZONA. 



BY STEPHEN SARGENT VISHER. 



In 'The Auk' for 1886-88, Mr. W. E. D. Scott published an 

 account of the birds of Pinal, Pima, and Gila counties of south 

 central Arizona. The list in the introduction to Bailey's 'Hand- 

 book of Birds of Western United States' is an abstract of Scott's. 

 It mentions about 230 species as occurring in Pima County. 



Mr. Herbert Brown, of Tucson, so frequently quoted, by Scott, 

 has, since 1888, published in 'The Auk' accounts of the occurrence 

 of (1) Purple Gallinule ('88), (2) Scarlet Ibis ('99), (3) Water- 

 turkey and Tree-duck (1906).

 me to announce are all based on the capture of specimens. 



In August, 1907, and during the months March to September,

 Herbert Brown's lists; and the relative abundance, etc., of certain 

 forms may with advantage be restated. However, the announce- 

 ment of the occurrence of the several additional varieties is not so 

 much the purpose of this article as the desire to add a mite to the
