OK, so some of the comedy weirdos have migrated into Animals and Nature. Clearly there is not a flock of peafowl to scare them off.
Your cat sitting on the couch = quite normal. This is what cats do.
Your cat refusing to leave said couch = still quite normal. This is what they do (I have 4, I KNOW this).
People scared of shrieking birds = not in the town centre on a Saturday night they are not. Ok, I'll be serious, the birds were on leads - how much damage can they really do?
The birds pooed everywhere = birds do that
If this noise continues in the mornings or indeed night = the noise should not start til daylight and should end at dusk. Peafowl are "roosters" and go to bed when the light gets low. As the days get shorter so will the noise.
The other stuff I've answered. But thanks for the laugh.
I've been meaning to clean the lappy - although not necessarily with lemon squash.
