Snowflakes or snow crystals form when ice crystals freeze around tiny particles of dust that are in the air, and join together as they fall. Ice crystals that melt as they fall become rain. Ice crystals that form near the ground are called frost.
Cardinals - this is one of my favorite bird photos ever. I love that cardinals stay around to brighten winter days, tho I don't see snow like this during the winter. But when the trees are bare, cardinals decorate it beautifully!
