I just noticed something about Rocky, our Amazon. Every day after work, I get Rocky out of his cage and put him on my shoulder so I can hold the paper towel under Einstein on the way to their perches (his giganto-poop sometimes explodes out of him before I can get to the perch). I've started to notice that every day Rocky sneezes a tiny little sneeze in my ear along the way. He's otherwise very healthy and doesn't seem to be sneezing at any other time. Do you think he could be sneezing because of something in my hair?
