SHEELFA, SHitFA, SHEELY. Localnamesfor the CHAFFINCH,

SHELD-DUCK [No. 285]. The name (from sheld=parti- 
coloured) occurs in Merrett’s list (1667) as ‘“‘ Shell Drake ”’ ; 
he gives it as a Norfolk name, but there is no certainty 
that it was intended for this species. Willughby and Ray

Bergander,” and observe that “They are called by some 
Burrow Ducks, because they build in Coney-burroughs ; 
by others Sheldrakes, because they are parti-coloured.” 
They, however, merely cite Bergander as found in Ald- 
rovandus.

“‘Sheld-appel.” Swainson thinks the “sheld” means 
parti-coloured as in SHELD-DUCK, and that the “apple ” 
is a form of Alp (q.v.). Merrett, Willughby, Pennant, 
Bewick and other authors apply the name, however, to the 
CROSSBILL, and much more appropriately, as the latter 
species literally shells apples, cf. Carew (‘Survey of Corn- 
wall,” p. 73, 1602) who says: ‘‘ Not long since there came a 
flock of birds into Cornwall, about harvest season, in bigness
