If any changes are made to your bird’s home, such as the decor inside or even outside of his cage, he might end up feeling afraid.
You can help your bird feel better about going to the vet by taking him around the neighborhood on short trips.
Some colors really pop out to a bird, so if you find your feathered friend is afraid as you approach, consider your clothing if nothing else around you has really changed.
Parrots, like all birds, are very sensitive to earthquakes. They may very well react with fright even before a human can sense it.
