88 THE BIRDS OF SHERWOOD FOREST. 
end is attained, we cannot withhold our faith in that 
Divine wisdom which both plans, and carries the plan 
into effect. 
The pretty Bohemian Chatterer (Bombycilla garrula) 
has several times visited us. The winter of 1850 was 
particularly marked by the appearance of several flocks, 
chiefly during the severe frost in January of that year; 
many were shot, and all of these had their craws filled 
with holly berries. 
The confusions of nomenclature were never, I think, 
more strikingly shown than in the family at which we 
have now arrived, that of the wagtails. Two or three 
specific and vulgar names are often applied to the same 
species by various authors, until it is extremely puzzling 
to make out which is meant. 
The pied, which was formerly considered to be the 
Motacilla alba of Linnzeus, but was found by Mr. 
Gould to be distinct, was changed to M. lotor by Pro- 
fessor Rennie ; it is now, however, thoroughly established 
as M. Yarrelli (Gould). 
The white, which is the true M. alba of Linnzus, is 
called cinerea by Latham, while Montagu says the name 
of white wagtail, is a name for the winter wagtail, which 
he then describes under the specific name of M. boarula 
(Linn.), which is known as the grey wagtail, called by 
Macgillivray the “grey and yellow wagtail,” and by 
Bechstein M. sulphurea. 
There are, in fact, three species, which are often con- 
founded under the trivial name of the yellow wagtail. 
The first is the one just named as the grey wagtail 
(M. boarula, Linn.); the second is the grey-headed 
wagtail (M. neglecta, Gould) the M. flava of Linnezus, 
and Budytes flava of Macgillivray ; and the third
