George Tanner’s bullfinch, a cock bird of this year, began from it’s first moulting to look dingy; & is now quite black on the back, rump, & all; & very dusky on the breast. This bird has lived chiefly on hemp-seed. But T. Dewey’s, & __ Horley’s two bull-finches, both of the same age with the former, & also of the same sex, retain their natural colours, which are glossy & vivid, tho’ they both have been supported by hemp-seed. Hence the notion that hemp seed blackens bull-finches does not hold good in all instances; or at least not in the first year.
