• Belongs to Russia

• No permanent civilian population — only a Russian military/weather station

Research has been performed with the intention of discovering how pigeons, after being transported, can find their way back from distant places they have never visited before. Most researchers believe that homing ability is based on a "map and compass" model, with the compass feature allowing birds to orient and the map feature allowing birds to determine their location relative to a goal site (home loft).

While the compass mechanism appears to rely on the sun, the map mechanism has been highly debated.

A prominent theory is that the birds are able to detect a magnetic field to help them find their way home. Scientific research previously suggested that on top of a pigeon's beak a large number of iron particles are found which remain aligned to Earth's magnetic north like a natural compass, thus acting as compass which helps pigeon in determining its home.However, a 2012 study disproved this…
