SYLVICOLIDyE — THE WARBLERS. 203 



Habits. The geographical distribution of H. celata is involved in some 

 doubt, o\Aing probably to its irregularity of migration. In a few occasional 

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

 been obtained near Philadelphia. Mr. Audubon affirms to having seen it in 

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

 Beyond that he did not trace it. Mr. J. A. Allen procured one specimen of 

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

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

 taking them for Hdin infhophagd rvjicapilla, he at first neglected to shoot any, 

 until, being in doubt, he procured one, and found it the Orange-Crown. 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 Pennsylvania, nor by Mr. 

 Boardman or Professor Verrill as occurring in Maine. I am informed by 

 Mr. Ptidgway that it is a regular spring and autumn migrant in Southern 

 Illinois, and in some seasons is quite common. 



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

 months, by M. A. Boucard. 



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

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

 curate, and much that lie attributes to this species we have reason to believe 

 relates to tlie habits of other birds. 



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

 from Cape St. Lucas to the arctic regions, where it breeds. Mr. Kennicott 

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

 Eoss met with them at Fort Simpson. Xantus obtained 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. This he 

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

 is sometimes consideral)ly varied, but is described as generally resembling 

 cr-r,r,i%r-she-up. 



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

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

 Nevada. In March they begin to sing their simple trill, which, he says, is 

 rather musical, and audible for a long distance. 



Dr. Coues met with this Warbler in Arizona, at Fort Yuma, September 17, 

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

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

 and making its liome 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. Heermann found a few pairs incubating near 

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