It only took my Yellow Nape Amazon a couple of days to adapt to this perch. He is 32 years old and has always slept on his swing. His solarium can get a bit chilly. He now prefers to sleep on this perch and at times chooses to stay on it vs. coming out to hang out on the top of his cage. I have the smaller heated perch for a Quaker. She is tougher to introduce new items to. She is still ignoring it.
