8 BIRDS OF GUERNSEY. 



and the Norway bird — the Gyr Falcon of falconers — 

 being the darkest, the Iceland Falcon (the present

 resident, as Mr. MacCulloch sends me a note of 

 one killed in Herm in December. All the Channel 

 Island specimens I have seen have been young 

 birds of the year, and generally killed in October or
