Re: Trex as a good smeller
Quoting don ohmes <email@example.com>:
I once made some casual observations on turkey buzzards, and found
that if _no_ visual could be obtained (eg, carcass _completely_
covered by brush), the birds could not access a armadillo carcass.
Much circling, possibly a landing, but no meal. My provisional
conclusion was that scent might bring them to a general location,
but visual confirmation was needed for final location.
This probably holds true for a lot of animals. Tiger sharks can follow
and hone in on a scent across huge distances, but once they get in the
general vacinity they tend to find the bloated snack visually. Hyaenas
also tend to move about in a search pattern once their nose has lead
them to an area with a potential meal, so scent doesn't seem to be
precise enough for pin-point accuracy.
Over short distances with little intervening cover sight is probably
the more reliable sense, however in circumstances where target objects
aren't sitting in plain sight (such as in forests, gullies, murky
water, or heavy undergrowth) scent might be the better option (since
you can literally smell something around corners).
