MIGRATION AND OTHER ORNITHOLOGICAL NOTES. 617 
Sparrow Hawk ( Accipiter nisus). — One settled on the 
Leman and Ower L.V. during the second week in October. 
Shag ( Phalacrocorax graculus). — One picked up on the 
tide mark on February 7th. On dissecting this bird I noticed 
a feature to which I have not seen attention previously called. 
There is articulated to the occipital bone at the protuberance 
a small spicule of bone about half-an-inch long which extends 
backwards mesially, to which the strong neck muscles are 
attached on either side. It does not articulate with the spinal 
processes of the vertebrae from which it is separated by muscles; 
it is obviously an accessory bone to give extra attachment for 
the weak muscles. 
Heron ( Ardea cinerea). — One seen to go from west right 
out to sea to the east on October 3rd ; on March 14th, one went 
out to the south-east. 
WlGEON {Mareca penelope). — Flocks coasting south just off 
the shore on August 6th, September 3rd and October 17th. 
Pochard (Fuligula ferina), Tufted Duck (F. cristata) 
and GOLDEN Eye ( Clangula glaucion). — Some still in winter 
resort on March 10th ; some of the last named adult males.

Smew (M. albellus). — One immature male near Lowestoft 
February 10th. 
Wood Pigeon ( Columba palumbus). — The migrations of 
this species, as witnessed here, appear at present very complex, 
and I can only state what has been actually observed. On 
February 18th and 29th, and on April 28th, flocks were seen going 
out over the sea to the east, and on March 29th to the S.E. 
Flocks were coasting north on March 27th, 29th, 30th, and
