I found this website last month and have been sharing with other Eclectus owners. Scroll down the page and click on the small circled arrows beneath each recording.
Eclectus Parrot (Eclectus roratus) | on-line sounds from xeno-canto/australia
Recordings of solomons and RS mostly. Distinctive calls of the males and females (in case you haven't heard one or the other). There's also a female calling for feeding; it's bottom left on the page and says "calls of female near nest hole". I recognized that one as typical of female (on eggs or with chicks) asking to be fed. There is some ambient jungle noise of course, so if you are not famliar with Eclectus, know that the loudest call(s) in each recording are the Eclectus!
Enjoy!
