I have had two budgies for 5 years. Today I found one of them dead on bottom of cage.
The other is calling for him all day. I showed him the body earlier when I removed it form the cage to try and make him realise he was dead and all he did was the "lets go and get food" call.
Do they grieve?
Will he be lonely now?
Is he too old to get a new, younger friend?
They were so close. I feel bad for him
