This could be just a couple of hours or returning from a long vacation. When I return from a vacation, my Amazons are very excited to see me again. If I were to reach in their cages and take them out when I first step into the room, they would bite me. After they calm down, they eagerly climb out of their cages and onto my arm, bowing their heads for a scratch or snuggling close to me. Each bird should be allowed to move at his own pace.
Some birds learn quicker than others.
Patience is the key. When a bird is pushed to do something he is not ready to do, he may let you know by biting. A BIRD TOO LONG Training session should always last less than 15 minutes. When the bird tires of his lessons, he may let you know by biting. Training sessions should always be fun.
