It might be time for this bird to break up.
Here's a useful tip: if your relationship is failing, a new pet won't save it. That goes double for a bird that can mimic the sound of your lovers' quarrels. All that you'll do is leave a living, breathing reminder of your unhappiness with a 50-year lifespan.
That's what happened with Peaches the cockatoo. Before she was adopted by her current owners, she lived with a married couple who ended up separating. Now, Peaches will launch into one-sided bouts of bitter shouting multiple times per day. The creepiest part is that she doesn't say any distinct words, but the tone is very clear. That means she eerily recreates the experience of being a kid and sticking your head under your pillow to muffle the sound of your parents fighting.
