Pigeons mostly have a reputation for crapping all over public monuments and annoying you when you try to eat lunch at the park. However, they’re also pretty amazing. They, along with many other species of birds, can travel thousands of miles and arrive at a precise location using only landmarks visible from the air. Some birds also have internal ferromagnets which help them determine their location within the Earth’s magnetic field. It’s like GPS in your head. For them, it’s just something they’re born with. For you, it’s a 200-dollar device you purchase at Best Buy. The birds win this round.
