NORTH AMERICAN BIRDS. 399 



to in these pages, there is a series of twenty-nine sets of these eggs — 

 three of two, nineteen of three, and seven of four. They were nearly 

 all collected in the vicinity of Tucson, Arizona. The typical eggs are 

 greenish-white, spotted with lavender-gray and ecru-drab. The follow- 

 ing are sizes often specimens: .95X.74, .98X.69, .93X.71, .92 x .70, 

 1.01X.76, 1.03 X. 72, 1.01X.76, 1.04 X. 74, 1.05 X. 75, 1.06 X. 79. The 

 average is 1.02 x .74. 



709. Harporhynclius cinereus Xantus. [14.] 



St. Liucas Thrasher. 



Hab. Lower California. 



This Thrasher is confined to the peninsula of Lower California. 

 Its general habits are described as being similar to those oi H. palmeri 

 or crissalis. Its nest is a flat structure, with a slight hollow, and 

 usually built in low trees, shrubs and cactus plants about four feet from 

 the ground. 



The eggs are two or three in number, and are described as green- 

 ish-white, spotted with pale reddish-brown. Average size 1.06 x. 75. 



710. Harporhynclms redivivus (Game.) [16.] 



Califoruian Thrasher* 



Hab. Coast region of California, southward along the Pacific coast of Lower California. 



This Thrasher is an abundant resident of the coast region of Cal- 

 ifornia. Mr. A. M. Shields informs me that its favorite haunts in Los 

 Angeles county are the scrub oaks and grease-wood brush that fringe 

 deep mountain gorges. It begins to build toward the last of April, and 

 by the last of May it is dijfficult to procure a perfectly fresh set of eggs. 

 The bird, he says, is a close sitter, often allowing one's hand to touch 

 it before leaving the nest. 



The general character of the nest is a coarse, rudely constructed 

 platform of sticks, coarse grass and mosses, with but a very slight de- 

 pression. Occasionally, however, nests of this bird are more carefully 

 and elaborately made. It is always well hid in the low scrub bushes. 



The usual complement of eggs is three, sometimes four and occa- 

 sionally only two. They are light greenish-blue, with russet-brown 

 and chestnut spots; average size 1.18X.85. Ten specimens meas- 

 ure 1.05 X. 80, 1.05 X. 82, 1.02 X. 79, 1.04X. 77, 1.08 X. 80, 1. 22 X. 84, 1. 21 

 X.85, 1.27 X. 82, 1. 28 X. 79, 1.30 X. 84. 



711. Harporhynchus lecontei (Lawr.) [160;.] 



Leconte's Thrasher. 



Hab. Valleys of the Gila and Lower Colorado Rivers, south into Sonora. 



This is the least common of all the Thrashers in the region which 

 it inhabits, and from all accounts it is a ver)^ shy and difficult bird to 

 obtain. Comparatively few of its eggs have yet appeared in collec-
