How come the Uruks could smell Aragorn, Gimli and Legolas tailing

>>79538830
Maybe because those where orcs and they were pretty busy besieging a city?

because they were taxed too hard to concentrate on scent

>>79538830
Those were orcs not Uruks.

because the wind blew the other way

Watch which way the flags blow orctard

>>79538830
why would they be alarmed by the smell of manflesh while outside of a massive city of humans

>>79538830
One of them farted

>>79538830
because there were no Uruk Hai like Saruman had in Sauron's army, their senses were not as heightened

what difference would it have made?

Weren't they a bit preoccupied at the momenr?

[Insert funny tax joke here]
