Concluding Remarks• Birds' navigation using Earth's magnetic fields → new

discovery, complicated process, involving biology/ornithology, biochemistry, and quantum physics (esp. quantum entanglement)

• Other taxa? Human?

• Bird migration and quantum entanglement: example of transdisciplinary research
