Hummingbirds delight with their brilliant colors and dizzying flight. But all that nonstop activity comes at a high energy cost, so how do hummers meet their calorie needs?

Discover the demands of migration, the nesting season, and even just getting through the night; plus learn how sleep differs from torpor. We’ll also spend time answering your questions about these flying jewels during live Q&A.
