I have owned my 3 year old jenday conure for just over two years. All of a sudden, about 3 months ago, he became obsessed with my feet. Every time I sit with him, he immediately goes down to my feet, starts rubbing his beak on them, regurgitating, and eventually, if I don't stop him, he starts humping them. I don't understand why this started happening out of the blue. I always stop him immediately when this happens, I will put him in his cage or have him sit with my boyfriend so he (hopefully) will figure out that it's not something I condone. But why is he doing it in the first place?
