Hmm, well, I have heard women being compared to singing birds (or more degrading as vultures or pen of hens if in group), but I’ve more often heard women being romantically compared to bees or flowers. Though, I don’t think I’ve ever heard men being compared to bees, but often to birds (eagles, vultures, seagulls, etc.).

Might also be local culture, as I usually think of harmony, nature, and perhaps matriarchy when pondering bees, while birds seem much more gender neutral, like, standoff-ish, elegant, brutal, impulsive, egoistic, even presented as predatory and evil in children movies and some media.

So, using common stereotyping, you can see where I’m coming from.
