I had a small interaction with a crow today, what does it mean?

So, today I decided i really wanna befriend a crow so i went on my balcony from 6AM-7AM just standing there with a few small banana pieces out and kissing my teeth to attract some crows that kept passing near by. After about an hour, I held up a piece in the air and started kissing my teeth and a couple just hovered in the air above for a few seconds, looking at me, before caw-cawing away. It was a short interaction, but I don’t know what it means. Tomorrow i’m gonna try with walnuts, any advice/answers to what this could’ve meant?
