Do not wait if any of the above symptoms are present. Bring your pet bird for a complete physical exam.
Birds have the capacity to mask signs of illness.
In the wild, a bird that behaved as if it were sick, would be hunted by predators and killed. For this reason, birds try not to reveal they are sick, and appear to behave normally as long as possible. Keep your bird warm and bring it to Aloha as soon as possible.
