Where is a bird's nose? What is it used for?

There are news reports,

Seagulls circling over the beach,

Sometimes he would swoop down and grab people’s potato chips.

(As expected, junk food appeals to everyone regardless of species…)

But how do they find the potato chips in the bag?

Birds have two black dots on their beaks.

It may seem a nuisance, but it is an organ after all.

Let’s say it’s useful, but in what ways is it useful?
