LOGGERHEAD SHRIKE. 



Lanius ludovicianus, Linn. 



PLATE LVII. Vol. I. p. 300. 



I HAVE received specimens of our common Loggerhead Shrike, of 

 both sexes and of various ages, from Dr Townsend, who procured them 

 on the Rocky Mountains and in the Columbia River district. These 

 specimens are in no respect different from those which I have obtained 

 in South Carolina, where it is plentiful. That this species should oc- 

 ciu- on both sides of the continent is not very remarkable, as several 

 other birds are in the same predicament. The Fish Crow, for example, 

 affords a more striking instance, as it is rarely found beyond the mari- 

 time districts ; whereas the Loggerhead Shrike extends its movements 

 far inland in the States of Georgia, Alabama, and Louisiana. This 

 species has been given as new, under the name of Lanius ExcuUto- 

 roides, in the Fauna Boreali-Americana ; but the description and figure 

 indicate nothing peculiar; and the nest and eggs described by Mr 

 Drummond, especially the latter, are similar to those of the Carolina 

 Bird. 



My account of the habits of this species being meagre, I have great 

 pleasure in laying before you the observations of my friend the Rev.
