A "lintwhite" is an older, somewhat archaic name for the common linnet, a small finch. The term refers to the bird's whitish winter plumage. It emphasizes the bird's paler coloration during certain times of the year. Essentially, it's a synonym highlighting seasonal variation. Think of it as the linnet's winter coat. It is less common now than "linnet." It's like calling a friend by their childhood nickname.
