I assume I'm looking at a male and female waterfowl but I don't know what kind (I feel like I've looked at so many ducks trying to figure it out)! The male has a dark iridescent blue/purple head, a blueish bill, both had brown eyes, orange webbed feet, and the female didn't appear to have uniquely coloured speculum feathers - I don't believe the male did either but I was more focused on the female's speculum so I can't 100% confirm the male. Please let me know what you think 🦆 and if I just missed an obvious duck
dust bathing
Barn swallow? Or bank swallow perhaps
