odd sound

[Mysterygirl]

Edgar (11.5 week old Alex) is making a sound that almost sounds like grinding teeth. Is this normal?

 

[Allee]

Beak grinding usually means your bird is happy, content and preparing to sleep.

A good sound. Happiness and settling in for bed Diesel does it every evening when he tucks himself into the corner of his cage for the evening xoxox

 

[Betrisher]

Love that sound! It means my Beaks are happy and at rest.

Rio does that too but not only at night . I can hear him in the day too specially when he is on my shoulder in the afternoon . He has also got out food from his mouth and puts it in my ears and loves nibbling my eyelashes. Is this normal? I tend not to encourage him sitting on my shoulders as I am wary of the bright red beak even tho he has never bit anybody.
Also I have a mango tree branch which will be placed in his cage as a perch . Is there any precaution I need to take before I place it in his cage?
