The press agency you are referring to is probably Mercury Press Agency. I have emailed them and they said that it was not them and the credit reads Mercury Press. This is the email they send: Neither the story, nor the picture, originated from our office here in Liverpool. We are "Mercury Press Agency" which is the by-line that normally identifies material that we supply. There may be some other "Mercury Press" elsewhere in the UK. If you manage to track down the source of the parrot picture published in the Daily Mail, I would be interested to learn the source since it may be someone "passing off" as my company.
