Pico is adorable! Great photos of him, I can see his personality shine through. Honestly... If he ever met my girl Mallorn, I can tell that they would 100% fight each other. Mallorn dislikes other birds but ESPECIALLy outgoing birds like herself. He seems like quite a ball of fun!
I know you know this (and I'm sure that the reason you took a photo of Pico stealing a bite of your sandwich was to show that he's a cocky silly thing) but I wanted to put a notice here for ALL members:
Please be careful with eating human food around your budgie. Foods high in sodium and with added sauces and sugars as well as processed foods are not good for budgies. It's best to have your budgie secured in their cage during human mealtimes, unless you're specifically intending for them to eat what you are serving (i.e budgie chop, etc.)
