I did that when I had to travel for a week.
I left a picture in the cage for Tweety. It was a selfie with him in the background.
I also left my desktop powered on so it can run things at certain times. At different times on different days, it would play some soft music, bird chirpings, jazz, or Christian rock.
At the same time every night was a prerecorded video I did. Was about a minute long of me talking to him. He was able to see the video pop up, see my ugly mug, and hear my voice.
Since my desktop was also on for the week, I had remote access into it so I can see him via the webcam I had pointed in his direction from the desk.
Did it do anything overall? No idea. My bird is like a cat. Just wants to be fed and not bother with me. Did it make me feel good doing it? Yes.
