Parrotlet Stress Seeing Wild Birds Out of Doors

Is it ok to put my parrotlet's cage in a place that has views out of
a window, including a view of a bird feeder? I typically get mourning
doves and house finches on my feeder. Part of the cage would be out of
sight of the feeder, but I want to make sure the sights and sounds would
not cause the parrotlet undue stress.

I don't imagine that would be an issue. Parrotlets can be aggressive and territorial with other birds but so long as they can't have physical contact, I don't think it would be an issue.
