OK, my hanging plant has become Party Central.
Came home, peeked out my blinds and saw momma bird, two big fledging heads, then, as I was watching
another dove flew in for a landing and the momma bird waddled to the edge of the plant, then flew off!! It's like they traded places.
I don't recall reading that male doves hung around to help out.
Could it be - the gods forbid - as
Jess suggested? Generation two already staking out the nest for the next brood?
