BREWSTER: BIRDS OF THE CAPE REGION, LOWER CALIFORNIA. 195 
As Dr. Mearns has recently pointed out, Mimus polyglottos leucopterus is an 
excellent subspecies, differing very appreciably, as well as constantly, from 
true polyglottos in having the general coloring of the upper parts less grayish 
(more drab); the under parts whiter posteriorly, and more strongly tinged 
with clay color on the throat and breast; the white markings on the wings 
much more extended and conspicuous; the general size larger, but the tail 
relatively shorter. In respect to all these characters the numerous specimens 
obtained in the Cape Region by Mr. Frazar are apparently typical of lewcopterus. 
Professor Baird thought that the birds of this region have shorter tails than 
those found in California, but I find the reverse to be the rule, although the 
difference is neither marked nor constant. 
The Western Mockingbird occurs throughout Lower California, and is 
probably resident wherever found. Mr. Belding characterizes it as “abun- 
dant’? in the Cape Region. Mr. Frazar’s experience does not corroborate 
this, for he says: “ While most numerously represented at San José del Cabo, 
it cannot be called a common bird either there or about La Paz, and at Tri- 
unfo I found it rather rare. It is very generally distributed over the low 
country, but it was not seen by me at all on the higber mountains.”’ 
Mr. Bryant affirms that this Mockingbird is “everywhere common” on the 
portions of the Peninsula which he visited. It is not known to occur north of 
California, and in that State is found regularly and commonly only in the 
central and southern portions. It inhabits nearly the whole of Mexico, except- 
ing the higher mountain regions, as far south as the Isthmus of Tehuantepec.
