TERNS: They cross thousands of miles of open ocean, powered by perhaps an ounce of body fat. If they miss target they die. Who taught terns where Antartica is? Trial & Error would be fatal. One generation of drowned terns and the species becomes extinct.
If you object to being considered ignorant, you really ought to take the time to find out the basic facts.
Firstly you refer to a specific species of tern, the Arctic tern. Secondly terns are seabirds and do not have to rely on their fat reserves.
Arctic terns follow the coastlines of northwest Europe and Africa, feeding as they go.
