era Texas and Colorado westward. During the winter of 1879-'80 Mr. 

 N". 0. Brown discovered about three pairs in a canon on Cibalo Creek, 

 near Boerne, Tex.; and Mr. William Lloyd found it common at Fort 

 Davis, Tex. 



718. Thryothorus ludovicianus (Lath.). [60.] Carolina Wren. 



An abundant resident in the southern portion of the Mississippi Val- 

 ley. Its movements in migration are very slight, and are confined to 

 the northern portion of its range, namely, southern Nebraska, southern 

 Iowa, and northern Illinois. The few individuals that find their way to 

 these sections retire southward in winter, and a slight decrease in num- 

 bers during the winter is also discernible south to about latitude 38° ; 

 below this there is no change. This species belongs more particularly 

 to the East, being seldom found west of longitude 99°. In Kansas, 

 where it is resident, it is abundant in the eastern but rare in the west- 

 ern part of the State (Goss). 



The form of the species once recognized as Berlandier's Wren (Thry- 

 othorus ludovicianus berlandieri), but not now considered distinct, occurs 

 in southwestern Texas. It was somewhat common at San Angelo during 

 the winter, and one or two were seen evei\y few days until May 6. It 

 probably breeds, though Mr. Lloyd has not yet found any nests. 



719. Thryothorus bewickii (Aucl.). [61.] Bewick's Wren. 



The distribution of this species over the Mississippi Valley is very 

 irregular. Abundant in some places and rarely or never seen in con- 

 tiguous territory, it seems to be governed by fancy in the choice of a 

 dwelling place. Like the Carolina Wren, it is not strictly a migratory 

 species, but leaves the northern portions of its range and winters from 

 southern Illinois southward. In summer it is exceedingly abundant in 

 southern Indiana and some parts of Illinois, being the common "House 

 Wren" to the exclusion of Troglodytes aedon. The same is true of east- 

 ern Texas, and of some places in Missouri. West and north of these 

 States it is not common. It is not common in Kansas, and is rare in 

 Nebraska. Dr. Hatch's note for Minnesota, stating that it is "common 

 in summer," would better express the facts did it read: a Not uncom- 

 mon during summer in a few localities in the southern part of the 

 State. 7 ' Its limited migration is performed in the last week of March 

 and the first few days of April. 



h\ the spring of 1885, at Gainesville, Tex., the first Bewick's Wren 

 was reported March 6, and the next March 28. At Pierce City, Mo., 

 the first was seen March 31. At Saint Louis the first was seen March 

 30, and the species became common the next day. 



719b. Thryothorus bewickii bairdi (Sal v.&Godm.). [61b.] BaircVs Wren ; Texas 

 Bewick's Wren. 



An abundant resident in Texas, and not uncommon in southwestern 

 Kansas (Goss). At Caddo, lud. Ter., only 30 miles north of the Texas 

 line, specimens of Bewick's Wren killed in December, when the species
