Thanks much for the fast input. I agree, my character can't call his girlfriend 'little funnel.' Funny, and probably not in a good way

In theory, 'little sparrow' is better, it's just a bird that I hate. English sparrows are not attractive, can't sing, make a mess, are aggressive, crowd out other birds. No redeeming qualities that I am aware of, at least for modern times. If someone called me his little sparrow, I might have to dump him for not knowing me very well

Whereas ravens are sleek, black, smart, mysterious, maybe a little dark inside. Much more interesting to me. Just sayin'.

If there isn't a another good diminutive for raven besides vorobushek, I'll have to think of another pet name that fits her.

Haven't read Catullus. Happily, Ms. Parker did it for me. Thanks for that verse.
