Have you ever wondered how monarch butterflies navigate the 3,500 km migratory journey between Canada and specific places in the mountains of central Mexico?

Neuroscientist and psychologist Barrie Frost will discuss one of the secrets behind the amazing migration of these delicate creatures at MiniU.

Novel research using an insect flight simulator shows how monarchs use the sun as a compass, wisely compensating for time changes as they go.

In addition, preliminary data show that monarchs use the smell of volatile substances they have deposited in previous years to find their traditional over-wintering sites in Mexico.

This session will examine how animals in general, and birds in particular, find their way over the very long distances they travel on their migrations.
