They have to find them first.

Yeup. Muscles and guts on the inside, muscles move legs like a row-boats
oars paddle in the water.

Vultures pick the meat off the bone, but they don't have teeth to naw the
bone clean.

 BF> I see, but HCl? And what is pepsinogen?

They're enzymes...an extract of pepsin from calves stomachs is sometimes
used on humans to aid in digestion.

 BF> OK. Sounds as you have done your homework.

Yes, it's against the law to shoot the predators in the field here.
Even the Black Crow is protected.

 BF> So much for a bird-lover, eh?

 I love them, they taste good.

 BF> Parrots are what we call American tourists. Colourfull and loud.  :-)

That's because some of them are from South America. The rest from Africa
and Asia.

 BF> Do you have another name for that dog? Haven't heard of German
 BF> short-hair pointer.

They may be called something else in Germany, but I wouldn't know off hand
what it is. You can find a full description of them on the American Kennel
Club's website.

Ahhh, nice looking dogs. We have a Sheltie in the house. He's a darling
little sheep hearder...
