Chris, i am attributing this specific event to the insanely long and intense mating season that many experienced in North America. Just months and months and months of highly charged behavior, so unusual in Salty. I also hold a private thought that while he reached puberty quite awhile ago, Its almost like now he is a full fledged rooster, a real cock of the walk so to speak. Saltys on the upper range of size for his species, a real bull of a yellow shoulder Amazon. If he were in the wild, I think he'd have a whole HAREEM of hens (even though they dont really do that) - but he's smart enough to game those chicks!
We did so many things to try and snap him out of it, hard to say what did it or what combination. Besides the Lupron shot, there was nothing like a 'magic bullet' that might have yielded quick results. You try something for WEEKS, and hope to notice improvement. Another thing we tried, bathing. So Salty is from an arid, dry scrubland island off the coast of Venezuela, not a jungle area. His species is highly localized. SO we have never given him baths or showers at any frequency approaching the usual 2-4 times a week a lot of parrots need. And he's not overly fond of baths and showers any way. But like 3 months or so ago, I stepped that up, to a daily little spritz in the AM, making sure to get the bald spot and then full shower like 4 times a week, a real soaking. We'd been on that limited schedule for almost 9 years, with no plucking or barbering at all. Did that increase in bathing help? I think yes, but who knows! We are just so ecstatic that he has turned it around.
I am curious/dreading December this year, like wanting to peek under a bandage, to see whats happening, but squeamish at what you might find. This whole thing has made me appreciate what owners of dedicated pluckers and barbering parrots go through and feel.
