Habits. The geojiTaphical disti-iljution of H. celata is involved in some 

 doubt, owing probably to its irregularity of migration. Ln a few occasional 

 instances tliis species has been observed in the Atlantic States. Several have 

 been obtained near Philadelpliia. 'Sh. Audubon attirms to having seen it in 

 the Middle States about the 10th of May, and in Elaine later in the month. 

 Beyond tliat he did not trace it. Mr. J. A. Allen procured one sj^ecimen of 

 tliis bird in Springfield, Mass., May 15, 1863. There were quite a number 

 among tlie fruit-trees of the garden and orcliard, then in bloom, and, mis- 

 taking them for Hcl iniiithophaga ruficujjilla, he at first neglected to shoot any, 

 until, being in doubt, he procured one, and found it the Orange-(-"rown. The 

 group passed on, and one was all he obtained. It is not given by Mr. 

 Turnbull as one of the birds of New Jersey and Peinisylvania, nor by Mr. 

 Boardman or Professor Yen-ill as occurilng in Alaine. I am informed by 

 ]\Ir. liidgway that it is a regular spring and autumn migrant in Suutlieru 

 Illinois, and in some seasons is quite common. 



It was taken as a migratory species at Oaxaca, Mexico, during the winter 

 months, by il. A. Boucard. 



Mr. Audubon's account of tlie habits and movements of this species must 

 be received with mucli caution. His description of its nest is entirely inac- 

 curate, and much that he attributes to this species we liave reason to believe 

 relates to tlie habits of other birds. 



On the Pacific coast it seems to he quite abundant, at different seasons, 

 from Cape St. Lucas to the arctic regions, wliere it breeds. ]\Ir. Kennicott 

 obtained several specimens at Fort Yukon and at Fort Kesolution, and Mr. 

 Eoss met witli them at Fort Simpson. Xautus obtaiued these birds both at 

 Fort Tejon and at Cape St. Lucas. It is common in Southern California 

 during the winter, frequenting low bushes and the margins of streams. Dr. 

 Gambel met with it in early spring on the island of Santa Catalina, where 

 he had an opportunity of listening to its simple and lively song. Tliis he 

 describes as commencing in a low, sweet trill, and ending in tshr-up. It 

 is sometimes considerably varied, but is described as generally resembling 

 er-r,r,r,r-she-up. 



Dr. Cooper speaks of this AYarlder as an abundant and constant resident. 

 of California, near the coast, and found in summer tliroughout the Sierra 

 Nevada. In March they begin to sing their sinqjle triU, which, he says, is 

 rather musical, and audible for a long distance. 



Dr. (.'ones met with this Warbler in Arizona, at Fort Yuma, Septeml)er 17, 

 at Fort Mohave, October 1, and also at the head-waters of Bill AViUiams 

 Pdver. Lieutenant Couch found it at Brownsville, Tex., seeking its food 

 and making its home among the low shrubbery. 



Dr. Suckley found it very abundant at Fort Steilacoom, in Washington 

 Territory, where it kept in sliady places among thick brush, generally in the 

 vicinity of watercourses. Dr. Heernuinn found a few pairs incubating near 

 the summits of the highest mountains on tlie Colorado River. The nests of
