At the beginning (and then again in Lines 131-132) of his poem John Shade (the poet in VN’s novel Pale Fire, 1962) compares himself to the shadow of the waxwing:
I was the shadow of the waxwing slain
By the false azure in the windowpane;
I was the smudge of ashen fluff - and I
Lived on, flew on, in the reflected sky. (ll. 1-4)
I was the shadow of the waxwing slain
