  Bruner 
  states 
  that 
  it 
  also 
  occurs 
  "across 
  the 
  line 
  in 
  Mexican 
  territory 
  

   for 
  some 
  distance," 
  and 
  that 
  it 
  is 
  confined 
  to 
  river 
  bottoms, 
  where 
  it 
  

   feeds 
  on 
  low 
  vegetation, 
  but 
  is 
  rarely 
  seen 
  on 
  tlie
