Common summer resident of half-wooded districts in Manitoba. 

 Breeding freely at Carberry, Shell river and Qu'Appelle. (E. T. 

 Seton.) A regular and common breeding species in Manitoba 

 generally and noted along the G.T.P. Ry. in 1906, west to Edmonton, 

 Alta. {Atkinson.) Formerly common but now rather rare at 

 Aweme, Man. (Criddle.) First seen at Indian Head, Sask., on 

 May 1 6th, 1892, they were never common; a few breed there, as 

 they were seen up to the end of June; first seen at Medicine Hat, 

 Sask., on May 14th, 1894, later they became common and doubtless 

 bred in the river valley; apparently breeding near Pend d'Oreille, 

 on the Milk river, Alta., July loth, 1895; observed a pair on May 

 1 8th, 1897, at Edmonton, Alta., building a nest in a clump of wil- 

 lows ; I unfortunately shot the female; nest nearly finished, com- 

 posed of weeds; observed one at Midway, B.C., April 6th, 1905. 

 (Spreadborough.) This is a more southern bird than Lanius borealis 

 and does not seem to advance further north than lat. 54°. Its habits 

 are precisely similar to the other, and its food, which was grasshop- 

 pers, the same. They are numerous on the plains. Mr. Drummond 

 found a nest in a willow bush, in the beginning of June, which was 

 biiUt of twigs of Artemisia and dried gprass and Uned with feathers.
