My Dad has trumpet vine at his backyard and the birds just love hanging out there. Last week, we looked in there to see if there is a nest and there we saw the morning dove just sitting in her nest. We don't really see if she has eggs because we never saw her leave the nest. Everyday, my wife would check if she leave but she's there every time.
I think other bird will fly away if someone would take a peek in their nest just like Robins do. But this dove is so brave, she would just stare at you and open up her wings, just like saying "Get outta here!"
Everyday, she also have different position. She is rotating inside the nest. I wonder if she is hatching already.
