Hab. Pacific coast district, from British Columbia southward to Lower California and Western 

 Mexico.

 those of Bewick's Wren. The eggs are white, finely speckled with 

 chestnut and lavender-gray. In remote regions it frequently nests in 

 crevices of rocks. Eggs, .64 x .50. 



719/5. Thryothorus bewickii bairdi (SALV. & GODM.) 



Baird's 'Wren. 



Hab. Southern and Western Texas, New Mexico, Arizona, south to Southern Utah, Colorado and 

 Middle Kansas, south into Mexico. 



This is a common bird in various parts of Southwestern United 

 States, as in Western and Southern Texas, New Mexico, Arizona, etc. 

 According to Col. Goss, it is not uncommon in Southwestern Kansas. 

 It was found common in the Lower Rio Grande by Dr. Merrill and Mr. 

 Sennett. Mr. Scott met with it in Southern Arizona. The only nests 

 he found were built in natural hollows, or deserted Woodpeckers' holes 

 in live oak trees. Dr. Merrill states that this bird has a great variety 

 of notes, the principal song being much like that of the Song Sparrow, 

 but sweeter. 



The nest of this Wren, besides being built in Woodpeckers' ex- 

 cavations and natural cavities of trees, is likewise placed in hollow logs, 

 under brush-heaps, or in any nook or corner about a deserted building, 

 and, when in a cavity, the space which it occupies is generally well 

 filled with roots, straws and grasses, lined with fur or feathers. The 

 nest is also frequently built among the twigs of dense thorny bushes. 

 Two or three broods are reared in a season. 



The eggs are usually five to seven in number, white, speckled 

 with chestnut or reddish-brown and lavender-gray, heavier at the larger 

 ends, and massed there in distinct, broad bands. Three sets of these 

 eggs from Comal county, Texas, are in Mr. Norris' cabinet ; two of 

 seven eggs each were taken April 4 and 25, respectively ; the third, 

 containing five eggs, was collected June 21. The sizes by sets in their 

 order are as follows: .65X.5O, .64x49, .64X.49, .68x.5o, .65x49, 

 .63 x 48, .65 x .50 ; .yix.si, .7ix.50, .69X.5I, .;ix.5i, .yox.sa, .;2x 

 .52, .7ix.52; -65X.50, .66x.5i, .64X.52, .66x.53, .6;x.52; average
