If there are cranes by a small pond should there be fish?
Hmm... cranes don't normally eat fish. They eat mostly insects and the occasional frog or lizard. If there are herons or cormorants at this little lake of yours, then there's your sign fish are present. It won't take these birds long to search an area for fish. If there are no fish, the birds will move on fairly quick. If they're there every day, well... do what comes naturally.
Cranes don't typically eat fish. They mostly eat insects, maybe an unlucky frog. If you're seeing herons or cormorants at this pond regularly, then that's your sign there's fish present. It doesn't take those birds too long to scope out an area for fish, and if there are not any there, the birds will move on. If they are there every day, grab your rod and reel and check it out.
