Arctic Tern at Barwon Heads, Vic on 28.11.10

["Mike Carter" <>]

Another Arctic Tern has been seen in Victoria. This time an adult at Barwon 
Heads last Sunday 28 Nov. It is image 2145 on www.peterfuller.com.au. This 
bird retains much breeding plumage in cap and dark underparts. It is Arctic 
because it has short legs; contrary to Common Tern, all plumage particularly 
wing, is very ragged because this species commences wing moult into 
non-breeding late, not until it reaches the Antarctic ice; etc. etc.
The width of black (quite a lot) on trailing edge of wing surprises me 
somewhat as have others this spring.
