I was recently asked my opinion about an article a macaw owner read that contained this passage.

In the age of 4-5 years, Macaws will begin to sort their own life and all training will become weak. Even the best trained bird will go his own ways and therefore all Macaws in Circus and other attractions will be replaced by younger ones. Training of adult birds is nearly impossible.

At the first hint of danger a bird naturally takes to flight. During the hundreds of defensive short flights that flighted birds take each day, they are quickly assessing potential dangers and deciding if they need to keep flying. These short flights require immediate and appropriate decision-making abilities. We call this process "Thinking on the Wing".
