The name on it is Vari-Crafts and I probably bought it at - well, I can't remember the name but it's a nation wide chain of bird-stuff stores. I hate to buy there as the prices are rip-offs, but sometimes I do get bulk seed - like 50# sacks - on sale. I fill it with sun flower seeds as they flow pretty well and rain doesn't completely gum up the works.
It has been fun watching the squirrels learn the lever 'trick'.
As for the bluejays - well, I spend about US$50 a month on 'animal' stuff. The bluejays here end up well fed. Actually, they like the MeowMix I throw out on the patio as much as the seed in the feeders. They'll come to within maybe 5 feet of me when there's a bunch of them and they 'feel cocky'. I throw out MeowMix or other cheap bulk cat food and the birds eat it, the 'coons LOVE it, the groundhogs eat a lot of it, but mostly in the spring. Skunks like it, as well. There are several wild cats which seem to like whatever I throw out, as well. Sometimes I put a bowl of peanuts inside the door (my desk is right at the sliding door) at my side and the more cocky 'coons come in and grab a few and take them to the patio to eat them. Not many rabbits show up for any length of time. I'd like to see more rabbits - I like them.
