WHITE-WINGED SHRIKE. 



(Lanius elegans, Swainson, North. Zool. ii. p. 122.) 

 Sp. Charact. — Clear bluish-grey, beneath unspotted white ; front- 

 let the same color with the head ; a broad white band across the 

 wing ; a slender and very cuneiform tail, entirely bordered with 

 white : 2d quill longer than the 6th, the 4th longest; the tarsus ex- 

 ceeding the length of the bill. 



A specimen of this handsome Shrike exists in the British 

 Museum, to which it was presented by the Hudson's Bay 

 Company. The particular district of its residence and 

 habits are unknown. It is readily distinguished by the 

 great quantity of white on the wings and tail, the narrower 

 tail feathers, longer tarsi, and less curved claws. 



Length 9 inches 9 lines ; tail 4 inches 5 lines ; bill from the angle 

 of the mouth 11 lines; from above, 8 lines; tarsus 1 inch 2^ lines. 

 Head and body above clear bluish-grey ; the tail coverts somewhat 

 lighter ; exterior margins of the scapulars nearly white. The lat- 

 eral marks on the head, the wings, with the exception of the white 

 parts, and the middle of the tail, pitch-black. The white band on 

 the wing 1^ inches broad, crossing the bases of all the primaries, 

 from the 2d to the 10th, inclusive. The secondaries broadly tipt 

 with white ; their exterior margins, and the whole of their inner 

 webs (with the exception of a black patch near the tips of the first 

 two), also white. The first primary and the three tertiaries are black. 

 The 2 central pairs of tail feathers very slightly tipt with white ; the 

 2 next pairs broadly tipt with the same ; the 2 outer pairs wholly 

 white, except the shafts which are brownish. Below pure white, 

 except the brownish tips of the quills and the centre of the tail. 

 Bill and legs blackish ; the lower mandible not pale at the base as in 

 L. horealis.
