Not to take sales away from mytoos, but while we're waiting for t-shirts, please check out avian welfare coalition website. They sell "Don't breed, don't buy - Adopt" t-shirt with different breeds of birds on them. I have a Senegal version, but need to get a 'too shirt. They are www.avianwelfare.org.
Also try the Indonesian Parrot Project. They are working with the Indonesian gov't to release birds, including Moluccans, that had been destined to be smuggled, but were confiscated by the gov't. www.indonesian-parrot-project.org.
They also sell MoluccaNuts, which my Abraham (M2) absolutely loves. And they sell nice t-shirts; I have one that says "(cocka)Too rights don't make a wrong" "Parrots give us wings" ... and to continue my sales pitch... Foster Parrots also has merchandise available, I believe. There are many avenues available to proudly display your beliefs on your chest or back, and support worth-while organizations at the same time. Happy shopping!! Carole
