He must have been hungry. 
My Goffin Cockatoo… barks like my dog did. 3 yaps a pause and 3 more yaps. She also has a “Devil Bird” impression…. Its pretty funny! It’s kinda like someone speaking in tongues. She also dances to “ Another one bites the dust”. She high steps to the bump bump bump another one bites the dust and when the synthesizer sound comes on she twirls her head around…. Its funny to watch. Its like she knows exactly what to do. She looks like she’s marching. She also has the Cockatoo Strut down pat… She can also be a sneaky little birdy, I watched her open her seed cup door in 1.37 minutes. She also tried the door latch but she couldnt get that one open.
We tend to let Bella free range in the house a large part of the day.
She spends much of the time in the kitchen.
We mostly have to depend on sound to know if she is up to no good.
Unfortunately.
Bananas don’t make much noise
At least Bella attacked only one banana. Mine would have taken bites out of the middle of each one.

You're lucky it's crows. Nameliss mimics the red tail hawk(s), owls, and other predator raptors. Yard gets dive bombing on semi-regular basis. I didn't realize how aggressive owls could be! Unlike your Scooter she continues. Her 'Vincent Price' laughs during the episodes convince me she knows just what is doing!
Piccolo copies my cough. He sometimes gets a terrible, awful cough if he isn't getting enough attention. He won't stop until we go over and ask if he is alright.Bella again.
This is a bit embarrassing.
Bella has a signature noise for my son and I.
She only does it now and then and it’s unpredictable.
For my son it’s the sound of blowing your nose.
When my son walks by she makes this blowing honking noise.
For me.
It burps
I walk past her cage and she makes a loud belch and says “Wes” very clearly.
I started a thread on “what noise does your parrot fool you with “.
No matter what the 'specialists' birdies can choose words they like to indicate things, people. Nameliss does mimic. I've spent weeks trying to figure out some things; the sound of dog kibble hitting dish and floor took the longest.
Well, there's an instant classic! Hysterical!!
Birds can develop obsessions about their people. Removing pierced earrings, necklaces, watches, barrettes, fingernail polish or tips and yes feet! My grey watched a sitcom where they did the foot tickling with 'woochie, coochie coo'. The actors would laugh and be silly. He then flew to coffee table I had my bare feet on. Rubbing his beak on bottom of my bare feet repeating that phrase. I ignored him and I am not ticklish there. He grabbed my big toe repeatedly saying 'woochie, coochie coo'. In terror I forced laughter. He laughed and kept ahold and repeating himself. He finally got tired and let me go. After that I wore shoes or socks and extra LONG pants plus used a blanket when laying on couch. When they get an obsession distraction works very well. The type depends on your birds personality. My grey only went after bare feet. In my case I had a reason and easy fix. Does your friend like toys, foraging items ect. I suggest that rather than food. You don't want to reward with a treat which has a chance of encouraging this behavior. Believe me, I sympathize completely. The terror of having that razor sharp nut cracking beak around my big toe has me very careful.
