There are swallows in "The Defense".
The avenue was paved with sunflecks, and these spots, if you
slitted your eyes, took on the aspect of regular light and dark squares... The
urns that stood on stone pedestals at the four corners of the terrace threatened
one another across their diagonals. Swallows soared: their
flight recalled the motion of scissors swiftly cutting out some
design...
If former mentions to swallow- hirondelles might suggest
adultery, even murderous intentions, in The Defense swallows,
like the black urns, bathroom tiles, sun-patches and checkered
curtains were among a multitude of different things (randomly
chosen?) that haunted Luzhin's imagination by implying a fateful
"design".
And then we find waxwings, sparrows,
ravens...
I'm sure there are more indications of Lammermoor, in ADA,
perhaps mainly related to Sir Walter Scott and his
writings.
VN also mentions La Traviatta ( in "The Defense", suggesting a
special penchant for prostitutes in the Luzhin household), La Bohème (
in KQK). There are probably many others ( Dmitri Nabokov, and Pavarotti, shared
a performance of La Bohème...).

& how Nabokov acquired his enormously rich store of words and idioms
straddling so many languages. He read so widely, listened abundantly, neologized
freely. I see him plucking out seeds and hints of seeds almost subconsciously,
building a richly-linked lexical matrix in his remarkably retentive mind.
