So Emma has started making some weird noises that I'm guessing someone out there can pin point. As I mentioned in my previous post, while I was out on vacation, Charlie and Emma started getting frisky. Charlie now seems to be in full nest building mode. He is hunting for materials around the cage and kitchen several times a day and is very persistent. This question is about Emma though. I set it up with this background information because I am guessing the behavior is breeding related. Emma will go into the nest and make this raspy wheezy really low volume call. It's definitely a call and not a health issue or her laying an egg or anything else like that. I have observed her closely. She occasionally just goes in the nest and makes this raspy low volume call. It almost seems like a call to Charlie to work on the nest. Any ideas what this call is all about?
