How do frogs find ponds?

Question

Sometimes a person will build a pond in their back yard, and a little while later find a frog and some frogspawn in it.

But there might not be another pond or body of water around for some distance.

It’s not like the frogs got a smartphone update telling them there’s a new pond 100 metres away in such-and-such a direction.

So this suggests frogs are constantly wandering around waterless pond-less environments all the time unobserved, and that some are lucky enough to happen across ponds to live in?

Frog eggs stick to bird legs. Birds move from water source to water source, rivers, lakes, ponds, including new ponds. Birds find new ponds easily from the air and land there, introducing frogs, bugs, and sometimes even fish. That’s how high isolated alpine lakes get fish in them too.
