western subspecies, and the same would be true of most of the records 

 received under the uame 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 Eiver. The same thing, in a still greater degree, ap- 

 pears in the notes for 1885. The records from eastern Illinois and Wis- 

 consin, from such reliable observers as Mr. Baliner, Mr. Ingram, and a 

 half dozen others, are fourteen days earlier than from corresponding 

 latitudes in Missouri and Iowa. £Tow, 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 scries of observations made 

 with reference to this particular \ oiut. The case is quite similar to lhat 

 of the eastern and western Meadowlarks, and is well worthy of future 

 consideration. 



In the fall of 1885 the last House Wren was reported from Grinnell, 

 Iowa, September 27; from Des Moines, Iowa, September 2C, and from 

 Saint Louis, Mo., September 29. The first one reached San Angelo, Tex- 

 September 11. Dr, Agersborg states that both typical T. aedon and T. 

 aedon parJcmanii breed in southern Dakota.

Parkmau'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 range in a 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, 111. Thus its course of migration 

 is seen to tend somewhat in a northeasterly direction.

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, 111., and Mr. Preston has found it as a not common breeder 

 in central Iowa, 



This Wren can endure cold many degrees below zero, and is fouud 

 during the winter in much of the heavy timber south of latitude 30°. 

 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
