Charlie,
The reason you cant buy spuggies or goldfinches is that toffs like Hughe Fergi Whipmybum. are regularly stuffing up to 13 of the poor little blighters up a hole marked exit only on larger bird species of the shrunk plastic variety.
I know this to be fact as I saw it on several programs in mid december.
Seems demand for both species is in a temporary decline however the government minister today was pleased to announce that he has contracted an analyst to investigate this down turn in the market.
Initial reports from the ministers brother in law sugest that early indications are not good for an upturn in the market, however his wife runs a company that with their marketing expertise these can reverse this disasterous trend and the nation will see an upturn in trade within the next 48 weeks.
