My oldest not tame budgie continues to try and take my food, I'd happily share it with him, but most of the food I eat could kill him.
I.E. has garlic, onions, salt, oil or stuff like that in it(dinner time, where he usually likes to come out and fly).
Though if I'm eating something that he could share with me, he's never bloody interested in it!
He will sit on my hand, finger, land on me, everything to get to my food, which is probably the only contact I ever get with him, so I tend to abuse it sometimes.
My SO get's a little iffy about me doing it, because it teaches him that he can eat off our plates, which is of course bad, but oh god, I can't resist it when my oldest gives me attention.
He's my world.
It's easy to see when he is interested in something I have, be it a yoghurt, bread, cucumber, something colourful, carrot, anything that is bright and funny to look at and that mummy is yumming.
I have a smaller cage on my desk that he usually lands on, next to my laptop, and if he's standing on that or my laptop he starts to bob is head up and down quickly and faces one eye to me, and puffs up a bit, and I know it's coming. I usually talk to him, ask him if he's eye balling my food, and then eventually, he jumps to me and insists on a taste, if I let him.
