Mine sit on the eggs and protects them fiercely - but since Cosmo is gender challenged, he nevers fertilizes them. I have a skirt on my cage, but they have seed spitting contests to see who can get them the farthest! Cosmo makes all kinds of animal sounds (barks, clucks, crows, meows, etc). We taught Cosmo songs like Andy Griffith, Jingle Bells, Beethovan's 5th, but he just puts them all together and makes up his own with parts of all the songs in them. And he picks up his own words without us teaching him like "Whatever!", "Can you hear me now?" and the telephone ringing. He also yells at Krysten just like I used to when she was running late for school. He loves to learn and play games like dropping things and saying "Uh Oh". They both used to be out of the cage alot but the cat we had could care less about them. In fact, they would tease him. Cosmo says "Here Kitty, Kitty, Kitty". But the 2 cats I have now have way too much interest in them, so I have to lock them in another room to let the birds out. And they love to eat off my plate, too. I never thought birds could be so much fun or have such personalities. If there were only moltless ones, they would be perfect
