THE RED-BACKED SHRIKE. 281 



winter, have been the same birds which reared 

 a brood in Europe the previous summer ? He 

 says it is migratory in Damara Land. Is the 

 same species, then, found on both sides of the 

 equator, migrating north and south on both 

 sides of it, but never crossing it ? 



The late Mr. Blyth thought that, with one 

 exception, our summer migratory birds do not 

 breed in their winter quarters, but from what 

 has been recorded of the Swallow, the Sand- 

 martin, the Wryneck, the Turtle-Dove and the 

 present species, there seems room to doubt the 

 correctness of this view. 



Another species of Shrike, the Woodchat 

 (Lanius rutilus), has been met with in this 

 country during the summer months, and has 

 been reported even to have nested here. It is 

 of extremely rare occurrence, however, and can- 

 not with propriety be included, at least for the 

 present, amongst our annual summer migrants.
