Little bowls for Sin
These were little dishes I got when Sin wasn't eating well. I'd fill them with seed and kept encouraging her to eat at every available interval. Sometimes she'd do the birdie equivalent of rolling her eyes, but most of the time she'd oblige, and it would feel so good having her eat and eat and eat.
I think a lot of times she'd eat because I asked -- occasionally, with these little bowls of seed in her cage, she might eat from them or turn to her preferred round metal dish, but when she was on me (and she kept wanting to be on me), I'd raise the little bowl to my shoulder where she was and cluck my tongue, which means there's food, and she'd eat to her heart's content there on my shoulder while I held the dish for her.
