AMERICAN ASH-COLOURED. 7 



sounds like skui. The name Arctic Skua seems to occur 

 first in Fleming (1828) ; it is the Arctic Gull and Black- 

 toed Gull of Pennant, while the name Richardson's Skua 

 is first found in Jenyns (1835), and was adopted by Yarrell 

 in his first edition. 



ARCTIC TERN [No. 420]. A more northern species in our Islands 

 than the COMMON TERN. It was first distinguished by 

 Brunnich in 1764, but was not noticed by our British ornitho- 

 logists until well into the 19th century. It is mentioned 

 by Fleming (2nd ed. 1840), but he considered it only a 

 variety of the Common Tern, and the bird seems to be 

 first admitted under the name of Arctic Tern by Yarrell in 

 1843. For derivation of Tern, see COMMON TERN. 



ARLING or ARLYNG : The WHEATEAR. Occurs in Turner 

 (1544), in Gesner and in Merrett. 



ARNT, ARENT. Given by Aldrovandus as English names for 

 an Eagle; no doubt equivalent to " Erne." 



ARRAN ARE : The RED-THROATED DIVER. The " ake " 



, is equivalent to auk. Swainson says it is so-called " about

 Willughby. Cognate with Dutch arsvoote, from the back-

 (Graham).

 " silver wing." 



ASGELL-HIR : The SWIFT. (North Wales) lit. " long wing." 



ASH-COLOURED BUZZARD, or FALCON, or HARRIER. See MON- 

 TAGU'S HARRIER. It is the Ash-coloured Falcon of 

 Montagu, formerly supposed to be the discoverer of the 

 species. 



ASH-COLOURED HERON, or HERN, or HERNSHAW : The COMMON 

 HERON. (Merrett.) Hett applies the first name to the 

 NIGHT-HERON, but Merrett's bird is obviously the 

 COMMON HERON. 



ASH-COLOURED LOON: The GREAT-CRESTED GREBE. 

 (Willughby.) 



ASH-COLOURED SANDPIPER. The KNOT in winter-plumage
