It's a boy...

...and a girl.

Weeble the Yellow Sided Green Cheek Conure is a girl, and Picasso the Painted Conure is a boy.

Weeble is saying "step up" fairly regularly, and clearly. She's using it appropriately, like when she is coming across the floor to me she'll say it, indicating that she wants me to pick her up.

Picasso is making kissy noises, in response to "gimme a kiss" or "can I have a kiss?", and accompanied by a beak kiss.
