(nah, the hash function of the vocalization mappings easily exceeds 512bits...)
I do wonder of they're actually naming themselves, or if they're being named by others.
Is there a handshaking protocol, where a bird says "hi I'm Fred" followed up by "greetings Fred!" "hiya Fred!"
or if it's more akin to schoolboy nicknames that stick. e.g. a bird yells at another bird "hey wifepooper, you're pooping on my wife!" and that target bird will never refer to themselves as 'wifepooper' but merely 'I'/'me', though other birds will refer to that singular bird as 'wifepooper'
