 and irregularly distributed in Scandinavia, but has never been met

Collared Turtle Dove. Dresser, vii. 51. 



One of these birds was shot here many years ago by Oelrich 

 Aeuckens. At the time I regarded it as a tame bird which had 

 escaped from confinement, and accordingly took no further notice 

 of it. The individual in question seemed to me at the time to 

 have more bluish-grey in its plumage than I had seen in cage-birds 

 of this kind ; and a subsequent examination of such tame examples 

 proved to me that I was correct in my previous notion. Hence I 

 entertain no longer the least doubt that Aeuckens' bird was i-eally 

 a Collared Turtle Dove in a truly wild condition, such as are resident 

 in Greece and other southern countries, throughout the whole of 

 Asia as far as China. This conclusion was further strengthened by 

 the plumage, which had all the fi'eshness of a wild bird.
