A male Eastern Bluebird from last year hanging out and eating Sumac seeds at the family farm. This are images #17, 18, 19 and #20. I learned something new wall looking up the Sumac Tree and its fruit. I had no idea that it was a useful plant at all, to me it was just a scrub tree that grow almost all over the place. In older times, Indians made a lemonade-like drink from the crushed fruit of this and related species. Sumac mark and foliage are rich in tannin and were used to tan leather as well. It is also used as an ornamental tree for its autumn foliage with its brilliant reddish coloration. I know that the birds love it and I guess deer eat it too.
