My 2 year old jenday is a bird I adopted about 1 month ago. He is finger tame and will sit on my shoulders and preen me without problems. I cannto, however,pet him at all. He has recently begun lunging and biting me whenever I ask him to step up while he is in his cage. The only way to get him out is to have him stand on a food bowl and he lets me carry the bowl out with him on it. Since I am new at this, I need to know what I can do to help him ovecome this behavior. Thank you.
