Refined Drinkers

It's been raining all day and it's still raining. There is rain on the grass, on the flowers, on the trees and shrubs, on the decks, on the clothesline, on -- well, on everything not under cover. Puddles of water are everywhere! So-o-o, why have the honey bees been bellying up to their regular drinking joints, namely the bird baths and the lily pond whenever the rain slacks off to a light drizzle? Is it a social thing? Are they too refined to drink just anywhere?

Drinking from the wet edges of a bird bath.

Drinking from a rock in the lily pond.
