We've known for some time that certain animals can navigate the Earth using it's magnetic fields, but the methods by which they do this have remained largely unknown.
However, an emerging field known as quantum biology is shedding light on this area and suggests that nature maybe taking advantage of quantum mechanics to develop its biological compass systems.
Physicist Jim Al-Khalili looks at one bird in particular, the European Robin, and how this species of migratory bird may be relying on the strange rules of quantum entanglement to find its way south each year.
Watch Jim's Friday Evening Discourse on the subject of Quantum Biology to find out more about the weird intersection between quantum mechanics and biology:
