great variety of kinds, differing in fize from the 
Nightingale to the Wren, and not a little in their 
habits and manners. They are widely difperfed 
over mofl parts of the known world ; fome of them 
remain with us during the whole year— others are 
migratory, and vifit us annually in great numbers, 
forming a very confiderable portion of thofe nu- 
merous tribes of finging birds, with which this if- 
land fo plentifully abounds. Some of them are 
diftinguifhed by their manner of flying, which 
they perform by jerks, and in an undulating man- 
ner ; others by the whirring motion of their 
wings. The head in general is fmall ; the bill 
Is weak and {lender, and befet with briflles at the 
t>£tfe ; the noflrils are fmall and fomewhat depref- 
fed ; and the outer toe is joined to the middle one
