BREWSTER: BIRDS OF THE CAPE REGION, LOWER CALIFORNIA. 201 
Troglodytes aédon aztecus Bairp. 
WESTERN House WREN. 
Troglodytes aédon parkmanni (not Troglodytes parkmanii AUDUBON) BELDING, Proc. 
U.S. Nat. Mus., V. 1883, 535 (Cape Region). 
Troglodytes aédon parkmanii (not Troglodytes parkmanit AUDUBON) Bryant, Proc. 
Calif. Acad. Sci., 2d ser., II. 1889, 316 (La Paz). 
Parkman’s Wren is included without comment by Mr. Belding in his 
list of birds “common to most or all of the localities where collections were 
made’’ “near the southern extremity of the Peninsula.’’ Mr. Bryant also 
gives it asa bird of Lower California, but apparently solely on the authority 
of Mr. Belding, who, he states, “ found it to be rare on Cerros Island, and col- 
lected a specimen at La Paz.’? Mr. Anthony mentions only 7. a. aztecus, 
which, he says, was “abundant in the pines’’ on San Pedro Martir in late 
April and early May, 1893.1 
Mr. Frazar’s collection contains five House Wrens, of which two were taken 
at San José del Cabo on September 29 and October 17, respectively, one 
at Triunfo on December 9, and two at San José del Rancho on December 
20 and 21, respectively. All of these birds seem to me to be referable to 
aztecus. They are certainly quite as ashy as average examples of that form, 
although in respect to the nearly obsolete character of the barring on the upper 
parts, they agree rather better with parkmanii. 
From this it will appear that the status of the House Wrens which occur in 
the Cape Region in autumn and winter is still open to doubt. It is quite 
possible, of course, that some of them are really examples of parkmanit which 
migrate southward from California, but more probable, in my opinion, that 
most if not all of them are representatives (not quite typical, perhaps) of 
aztecus, which pass their summers at San Pedro Martir and other elevated places 
in the more northern portions of the Peninsula.

Mr. Belding gives this Marsh Wren as “rare ’’ in his list of species found at 
San José del Cabo from April 1 to May 17, 1882. The birds which he saw on 
this occasion were probably only belated stragelers from the hordes which
