Canary sits on bottom of cage?

My canary seems very healthy. Just within the last hour he has been singing and he came out of his cage to fly around. But most of the time when he is in his cage (except when he sleeps at night) he likes to sit on the bottom. As I type this he is sitting on the bottom of the cage singing. Is this a sign that he may be sick or is he just a weird canary?

I would say you have a psychologically well adjusted canary. :-)

Birds go to high places for security where predators can't reach them. Unless there is food below, they normally don't like it down there. If there is nothing over or at the top of his cage that might make him nervous, I would think he is just comfortable.
