Yes, I had a similar experience with MAARS. I offered to teach classes to people wanting to get a large parrot as I had over 10 years of experience with 5 large parrots that I owned a Yellow Naped Amazon, a Citron Crested Cockatoo, a Congo African Gray, a Blue & Gold Macaw & a Rosebreasted Cockatoo. My experience included handfeeding all of them when they were on 2 feeding per day except the Yellow Nape. I also clipped my own birds wings & I gave 1 of the parrots shots in his chest & rinsed his nasal cavity with a solution because it turned out that he was sick when I got him from a pet shop. That was the Yellow Nape, my first large parrot. MAARS said that I could only clean cages. They said that is what all volunteers do. Well I work with another rescue & I don't clean any cages for them. But they do have other volunteers who do clean cages.
