My family has a bunch of Parakeets, we used to have 2 normal gray Cockatiels, Brady and Moss, who were brothers. But then Brady escaped outside and never came back.
He was a real character, though...
Very sarcastic and lots of attitude.
When someone walked by he would swing his head down as if to scoop something up, then he would make a loud chirp sound. It was so funny! He would tap his food dish and his perch and the side of his cage if he heard any tapping noise, and he liked to chirp and bob his head. He never learned to talk, he just made really funny chirping, whistling, and clicking noises and liked to bob his head and "take a bow" (the scooping head motion) and tapping things with his beak. I still miss him, even if he wasn't the nicest bird...If anyone put their hand up to him, he would hiss and scream at it and then bite it REALLY hard (hard enough to make it bleed, which happened a couple times...
).
Moss, on the other hand, is still learning to talk a little. When I say, "Take a bow!" He will often bow his head down and let me scratch it.
He's still getting the hang of it...He will mostly only do it when he wants to.
On nice, sunny days, he will make a variety of loud melodies that we never taught him. Maybe the people before who owned him taught him and Brady? We got them only in 2008 on Christmas Eve, so neither really learned much. Moss also does the tapping his beak thing like Brady used to. He can whistle and can almost say, "Pretty pretty bird!" But it sounds more like a whistle that goes to that tune. He hasn't learned to sound out the words yet.
Oh and Moss and most of the Parakeets will eat from my hand.
They often beg for treats (pieces of bread, lettuce, anything really) and are so spoiled!
