Troglodytes bewickii. Thryothorus bewickii. Long-tailed House Wren. 



Geog. Dist. — Eastern United States, north to New Jersey and 

 Minnesota; rare east of Alleghanies; west to southeastern 

 Nebraska and eastern Texas. Breeds irregularly throughout 

 its range, having its center of distribution in summer in 

 southern Missouri, southern Illinois and southern Indiana 

 and is said to extend its range eastward through Ohio. 

 It winters in the southern United States from southern 

 Missouri southward. 



All through the Ozark region and Ozark border the Bewick 

 is the common House Wren, and there is hardly a farm house 

 without its Bewick Wren, while in the towns there is one or more 

 in every square. There it takes the place entirely of the House 

 Wren, which occurs in southeastern Missouri only in counties 

 bordering the Mississippi River. It is not known to occur in 

 western Missouri outside of the Ozark border region (rare at 

 Jasper, not known at Appleton City, Warrensburg, Indepen- 

 dence, etc.). In northern Missouri the species has not been 

 observed west of Howard Co. (Fayette, March 12, 1903), but 

 is reported from Montgomery City and reaches irregularly our 

 northern state line, following the bluff region along the Missis- 

 sippi to Warsaw, 111., and Keokuk, la., where it was noted 

 April 20, 1896, April 10, 1898, April 9, 1901, and April 19, 1903, 

 with an apparent increase in numbers, according to Mr. Currier. 

 Some winter in southern Missouri even as far north as St. Louis 

 Co. (Old Orchard 1896-1897) and Miller Co. (Iberia, February 

 3, 1905), but the bulk retires to more southern regions, returning 

 in March and leaving in October. Being a much better singer 

 and not so meddlesome the Bewick is greatly preferred as a 

 House Wren, but is often dislodged from its nesting site by 

 aedon, where the two species occur together.
