For the birds....

With spring here now, I have my mind on bird baths and bird feeders.  I have a book somewhere with a beautiful picture of a homemade bird feeder using a green bottle upside down.  Anybody got any pictures of neat homemade birdfeeders?

something like this, but wrapped very ornately with wire and made with a large green wine or old GLASS pop bottle.  There were 50 gazillion "results" having do to with making bird feeders from 2 liter pop bottles, NOT what I'm looking for.  I'm cross-eyed from scanning the print.

I saw this one on ebay.  And I know I saw a blogger recently make something similar out of a Starbucks Frappacino bottle!  It was cute.  I'm calling for pictures and ideas here.....and maybe some links?  Maybe someone should do a linky?
