I replaced that Java perch with one of my NU Perches that I invented and the problem went away within about a month or two!

I did tape a heat sensor to one perch right after I got it and ran it in an empty cage and the temp of the perch never went over 103F. A small perch would not be comfortable for a macaw, and a huge perch would not make a budgie very happy.MET Safety Laboratories suggests unplugging the bed if you leave your home on an extended vacation, as they do with any electrical appliance. This is an extremely safe heater in our experience; it’s now been on continuously for about a month and always maintains a consistent and comfortable temperature. One thing to watch out for is the power cord that comes out of the cage; it’s wrapped for their safety as far as not being able to chew through the cord, but mine tried anyway.

Use the warmed water for thier drinking nipples and then could use some kind of filter to pump it through some tubing then it would give them heated perchs.Our bird loved it no matter where he was and he had four cages with Thermo perches installed They are really durable in having an irregular shape much like a natural tree branch which makes for good foot health and reduces the chances of sores or “bumblefoot”.
