Hi. I am new to owning parrots (and to forums). I have 4 cockatiels(2 girls,2boys) which I have head reared with a LOT of help. Now that they are grown my neighbour complaining about the noise. They have the run of the house unless I go out. They have a play area with many toys and enrichment activities. I only notice the noise in the evening just before they go to bed but now even when they just sing I am concerned. Can anyone tell me how to make them quieter or how I can record to prove they aren't noisy if they complain to council again ( council said they were fine)
