I am probably not the one to teach you about feeding a Sun Conure. I am not sure if they eat just like a cockatiel. I give TD pellets, very little seeds, lots of different veggies. I try a lot of them, but he's not big on fruit, except apples.Meanwhile can you help me or teach me about how and what to feed Rio
However, I can't remember where or when I read that you should eat with your bird bcuz birds (at least cockatiels) eat together as a flock. I tried it...and you should see how happy it makes him when I stand or sit by his cage and munch on anything...he stops whatever he's doing and runs to his food bowl and starts eating... it's really cute how he keeps looking up, checking to see if I'm still eating with him!
I have also found that if I want him to try something new, it is almost guaranteed he will try it if I eat whatever it is that I want him to try in front of him and I make a big deal about it... saying, "yum yum yum yum". Then I'll offer him a little piece of whatever it is and say, "try some". It almost never fails!
