Our male Ekkie has been very well behaved for most of his 9 years of living thus far. Into the mature male zone and actively procreating with his mate, he has shifted behavior a bit. When he's separated from his female, he can unleash some really distressing squawks. But for the most part, when she's around he has a certain signature tweet.
TLDR; He has a terrible new squawk sound; is there any way to discourage it?
Lately, this has changed. The female is a horrible noise maker. The only solace we get is when she's nesting. She lays an egg, we swap in a fake, and she keeps going for a good 30+ days. It's BLISS. Outside of that, she never tweets. She lets out a very loud discordant squawk, usually spaced about a minute apart. Well, our male... despite a good 2 years of his hearing her, has now decided to imitate her. So, sometimes we'll hear the super loud nasty squawk, then realize it didn't come from the female--it was him. There are some differences. He'll do 3~4 in a minute and they're a bit "tinny" compared to the female.
Because of a job change and people at home more often, we've let him out a bit more during the day. Generally this has helped his mood. But we try not to leave both male & female out a lot together. That's because in between egg laying times, the male will just suddenly badger and harass his mate. When he builds up to a crescendo and attacks her, we pull him back and then usually put him in his cage. When his mate is nesting, he's very attentive and nice with her. He's a very copious feeder. I nicknamed him Mr. Regurgitation.
He does the feeding to her and to his son, who is in the cage next to hers.
Anyway, now that I've set the stage...
I'm starting to wonder if letting him out frequently got him into believing that this is the new norm. When we are in the cage area (the kitchen is adjacent), he will start with his usually friendly "hello I'm here" chirps. They can be pretty loud, but they're harmonious. But, if we ignore him, he'll then shift and start cawing, like a crow. Then he'll kind of caw-bark. Then he'll start another loud squawk that's semi-unpleasant. And then... BANG. He starts making this very loud and very discordant squawk. In a way, it's nastier than what the female squawks. And the trouble with him is that he'll unleash like 5 or 6 of them in the span of a minute. Nobody taught him this sound. None of the other birds make it.
So in terms of "emotional state" of a bird, is it that when they're frustrated they will come up with different kinds of very loud & harsh sounding squawks? I'm assuming it's frustration. He wants to come out, but we're not in a situation where it's time for that. Still, he sees us, and probably thinks to himself--you're here, I want out, come let me out. NOW!
We do not reward this behavior. We try to ignore it. And then when he makes a pleasant sound, we try to reward that by paying attention to him. Coming over, checking on his cage, changing his water, etc. Another thing is, we have a thin curtain for the opening to the kitchen from the cage room. It's a great deterrent to keep the birds from flying into the kitchen. Most of the time we have it open, but we'll draw it closed when cooking. The birds are of course super sensitive to sight and sound. The curtain being open is preferable to them, because they can see more. So, when the male starts his nasty squawking, I'll close the curtain so he can't see us. Usually he keeps up his squawks and eventually tires. We'll pull back the curtain when he stops. But I don't know if the curtain is helping to deter him.
As a rule of thumb, is there any recommendation for how to discourage this kind of squawking behavior?
