Grackles ?

[SmartWombat]

I'm pretty sure the black birds are Grackles, in the sun they have beautiful irridescent purple on the back & wings.
But what's with the heads-up pose?
Some kind of territorial display?

The not black one is a female The boys are showing off to her.

Edit-- Actually, no, maybe not, beak seems wrong on the not-black one. But the the smaller common grackles around me do this around females.
