western subspecies, and the same would be true of most of the records 
received under the name of the House Wren. It will be noticed that in 
the notes for 1884 it is said that there is an intimation that migration in 
Illinois and Wisconsin was a week or ten days earlier than that west 
of the Mississippi River. The same thing, in astill greater degree, ap- 
pears in the notes for 1885, The records from eastern Illinois and Wis- 
consin, from such reliable observers as Mr. Balmer, Mr. Ingram, and a 
half dozen others, are fourteen days earlier than from corresponding 
latitudes in Missouri and Iowa. Now, if in these records for both years 
the House Wren and not the Winter Wren was the bird really seen, it fol- 
lows that there is a clearly marked difference in the times of migration 
of the eastern and western House Wrens. To fully determine this point 
the records of the observers in the district east of the Mississippi Val- 
ley would have to be consulted and a careful sc ries of observations made 
with reference to this particular point. The case is quite similar to that 
of the eastern and westein Meadcwlarks, and is well worthy of future 
consideration. 
Tn the fall of 1885 the last House Wren was reported from Grinnell, 
Towa, September 27; from Des Moines, Iowa, September 26, and from 
Saint Louis, Mo., September 29. The first one reached San Angelo, Tex: 
September 11. Dr. Agersborg states that both typical T. aédon and T. 
aédon parkmanit breed in southern Dakota. 
721a. Troglodytes aédon parkmanii (Aud.). [63a.] Western House Wren; Park- 
man’s Wren. 
Parkman’s Wren is a bird of the Western States, coming east to the 
Mississippi Valley. - After what has been said of the eastern form but 
little remains to be said of the western. Its rangeina north and south 
direction is about the same as the foregoing, and the dates of its mi- 
gration are also much the same—possibly a little later. Concerning its 
eastward extension, it may be said to be common in western Texas, and 
it was found at Gainesville in north-central Texas in the spring of 1884. 
It is a common summer resident in Kansas, and is common in Ne. 
braska, Dakota, western Minnesota, and western Manitoba. It has 
been taken several times at Chicago, Ill. Thus its course of migration 
is seen to tend somewhat in a northeasterly direction. 
722. Troglodytes hiemalis Vieill. [65.] [inicr Wren. 
Breeds from the Northern States northward. Mr. H. A. Kline tells 
us that it nests in the rubbish along the banks of a stream one mile 
west of Polo, Il., and Mr. Preston has found it asa not common breeder 
in central lowa. 
This Wren can endure cold many degrees below zero, and is found 
during the winter in much of the heavy timber south of latitude 39°, 
Most of the birds winter between latitude 34° and latitude 37°. In 
the spring of 1884 its migration took place a week or ten days earlier 
than in 1883, The migrants reached latitude 39° about March 20, and
