I'm not an Eclectus expert by any means. But it could be a couple of things.
- The reality of this is my new home is setting in...
- Your not returning her contact call(s)...
- Your not communicating with her while you are in different rooms, which are out of her sight.
Parrots in general, like to keep in communication with other members of the flock even when they are not insight of each other.
She may not call back at first, but after a bit (days, weeks), she will.
There are other possibilities, but since you are getting a contact call when you are leaving the room. They are less likely at this point. Welcome to the need to be a crazy bird person! So, talk, whistles, singing, or anything to let her know you are around.
Enjoy!
I want to second this comment above.
We adopted a bonded pair of Eclectus a few years back. We wanted to teach them to talk. Instead they have taught me/us to speak Eclectus.
It's crazy, I have literally learned to speak their language, and boy do they have a language. It's a bit hard to put their noises into human text, but they absolutely love to communicate with everyone they live with. From Us Humans, to the other birds, the dogs and also the wild birds outside. So now that we are hand rearing a baby Eclectus, we have stopped trying to teach the parent birds to talk human, but have instead doubled down on learning their language. I think it could possibly be as much fun as teaching them.
As my experience with Eclectus grows, I am starting to form the opinion that Eclectus are a kind of teaching bird. By that I mean that they will teach you things, correct you, growl at you when you get it wrong. They will keep repeating it till you get it right. Some sounds I can not make, they are are just waaaay too high pitched, or sometimes too complicated. I think they get amusement from producing sounds that I can not, then watching me try anyway. they are so funny. It gives us hours of enjoyment (all of us).
I think Someday I will make a video of their language.
Some examples are: They Call my Wife and I "Wah Wah" and "Wow Wow" lol. One really common one they do is a bit like a test of how you are feeling and are kind of asking if you want to talk or play. They make a sound that goes something like "Doo doo doo Dit" It's high pitched, the first 3 syllables are the same pitch, and the last is at least a few notes higher, a bit like an upwards inflection. I love it. I wish I could have had a career or job that allowed me to study their calls in the wild. There are so many more, and they are largely too difficult to reproduce with text, but someday I will make a video of their (Our Pair) language.
