Feisty and elegant, hummingbirds are amazing creatures.

To live their high energy lifestyles hummingbirds must sync their migration and nesting times with the flowering of nectar-bearing plants, but climate change threatens to throw off this delicate balance.

We need you. With today's technology we can all become citizen scientists, spending a few minutes each week to collect data in our communities that will be invaluable for researchers.

Join Audubon's Hummingbirds at Home to help crowdsource rigorous data that can uncover how hummingbirds are affected by climate change and provide the information necessary to help them.

How does it work? It's easy.
