I just wondered whether the human digestive tract is the same as a
birds...... gastric juices etc..... I was hoping we might have someone in
the group who knows about stuff like that :~))


In terms of digestion seeds go through same acid then alkali bath. 2 main
differences ( that I know about) 1. birds do not have teeth but a gizzard
which is a sort of muscular tube which contains swallowed stones, which acts
as a giant sanding machine instead of straightforward mastication, 2. birds
excrete dried out uric aid with their faeces which give them a low pH ( the
faeces)compared with humans. you can mimic the process on seeds by abrading
and swirling in acid.
