Bring on the caviar! Not something you expect to hear in the northern Chihuahuan Desert? That's true, though perhaps not for the reason you might think. Caviar consists of the roe, the eggs, of a group of fishes, the sturgeons. Today, we tend to think of Russia when caviar is mentioned, but at one time North America was the prime supplier.
Now, we have no indication that the Chihuahuan Desert ever was known
for caviar, but sturgeons did exist in the Rio Grande of New Mexico, and historical
archaeological evidence suggests that at least its flesh was consumed. The key words
here are "did exist", for it's not been known from the state since about
1875. Little changed from the days of the dinosaurs, sturgeons are bottom feeders that
vacuum up eatables from mud. Why are there no surviving sturgeons here? No one knows
and, barring reintroduction, the chances of it occurring here once again are virtually
nil. Nevertheless, if ever it's reintroduced, somebody is sure to shout,
"Bring out the champagne and caviar!"—and somehow, that seems entirely
inappropriate!
