LUCY'S WARBLER IOI 



Adult $, Spring. Similar to adult d" in Spring but with the chestnut of 

 crown and tail-coverts averaging paler in color and less in extent. 

 Adult $, Fall. Not seen. 

 Young $, Fall. Not seen. 



Nestling. No crown-patch; crown and back brownish gray; upper tail- 

 coverts cinnamon; wing-coverts and tertials edged with cinnamon; below white 

 washed with buffy. 



General Distribution. Western United States, breeds com- 

 monly in Arizona and rarely north to the lower Santa Clara Valley, 

 southwestern Utah. Winters in northwestern Mexico. 



Migration. Its arrival in Arizona was noted at Fort Lowell, 

 March 20, 1902; Oracle, April i, 1899; Fort Mojave, March 25; 

 Whipple Barracks, March 31, 1892, and in the Huachuca Mountains, 

 April 8, 1902. 



The Bird and its Haunts. The restricted range of this species 

 has brought it within the field experience of comparatively few orni- 

 thologists. Discovered by J. G. Cooper at Fort Mojave, Arizona, 

 March 25, 1861, where it was not uncommon in the mesquite chaparral, 

 it was taken two years later by Holden and in April, 1865, was found 

 by Coues at Fort Whipple. 



The nest was first found by Bendire at Tucson, Arizona, on 

 May 19, 1872, additional examples being discovered by Stephens, as 

 recorded by Brewster 1 , at the same locality nine years later. 



Coues described the Lucy's Warblers which came under hi.- 

 observation as "rather timid, retiring birds, likely to be long over- 

 looked in the thickets and copses to which they seem to be much 

 attached." Stephens, however, states that "although active and rest- 

 less they were not at all shy." He adds that "they were more abun- 

 dant among the mesquites than any other species and their tseeping 

 could be heard on every side. They were continually in motion, flying 

 from tree to tree, and occasionally visiting some low brush in the 

 vicinity." 



Howard 2 writes that Lucy's Warbler is fairly common along the 

 river bottoms throughout southern Arizona, especially in the mes- 

 quite and willow thickets. 



Song. The song of Lucy's Warbler does not appear to have 

 been described. 



Nesting Site. Recording Stephens' observations on the nesting 

 habits of this Warbler in Arizona, Brewster 1 states that the site 

 was "variable; the characteristic place, like that of the specimen 

 discovered by Captain Bendire, was behind the loosened bark of a 

 large tree, but use was frequently made of old Woodpecker's nests, 

 knot-holes, and in short, all sorts of crevices." One pair appropri-
