from the Maritime Provinces and Ontario to Virginia, Ken-

In Missouri a rather common winter resident from the latter 

 part of October to early March. Earliest dates at Keokuk, 

 October 25, 1900; October 27, 1896 and 1901; October 31, 

 1897; latest, March 7, 1896 and 1897, March 9, 1902, and March 

 17, 1901; April 9, 1899. Earliest at St. Louis, November 2, 

 1906; latest from St. Joseph, April 7, 1896. Mr. Chas. L. 

 Eimbeck has three fine specimens in his collection taken near 

 New Haven, Mo., but there are at present no records available 

 from the state south of St. Louis and Franklin Counties.

 Shrike. 



Collyrio excubitoroides. Collurio ludovicianus var. excubitoroides. Lanius 

 ludovicianus. Northern Loggerhead Shrike. 



Geog. Dist. — Greater part of the United States east of the 

 Great Plains, but very local in more eastern districts ; breeding 

 north to New Brunswick, Maine, New Hampshire, Vermont, 

 northern New York, Quebec, Ontario, Michigan, Wisconsin, 

 Minnesota and southward to midland Virginia and western North 

 Carolina, Kentucky, Missouri, and eastern Kansas; in winter 

 from Missouri, etc., southward to Mississippi, Louisiana, Texas. 



This new subspecies has lately been separated from typical 

 ludovicianus, which occurs only in the South Atlantic and Gulf 

 States, while the range of the western subspecies, excubitorides, 

 the White-rumped Shrike, does not reach our state, terminating 

 in central Kansas and eastern Nebraska. In Missouri, a fairly 

 common summer resident on cultivated land, chiefly in the 

 prairie and Ozark border region, scarce in the Ozarks and the 

 southeast. In mild winters some remain at their breeding stands 

 from the Missouri River southward, but the majority leave the 

 state in October and do not return till the third week of March, 

 when the first Shrikes are back at their stations in all parts of 

 the state. Full numbers are present before the end of the 

 month, when the old pairs have already begun building their 

 nests, the species being among the earliest breeders, having 

 fully fledged young in the fourth week of May. They make 

 very amusing pets, being remarkably bright and the males 

 somewhat musical.
