As an Important Bird Area, Boyce Thompson Arboretum and the adjacent Arnett and Queen Creeks are known for spectacular birding opportunities.
Some 275 different species have been sighted. Guided bird walks take place between October and May.
Named the “most enchanting” Audubon Important Bird Area in Arizona, Boyce Thompson Arboretum provides important habitats and resources throughout the year, qualifying the site under the criteria “exceptional seasonal diversity of land-birds,” as well as “outstanding land-bird stopover site.” BTA’s riparian habitat, which provides for riparian-dependent species as well as rare and threatened species, is an exceptional example in a state where these important areas account for only one percent of land area. Of the 275 species recorded in the IBA, 62 are species of Special Conservation Status in Arizona.
This combination of high species richness and occasionally high numbers of migrants is ecologically significant and provides a remarkable opportunity for visitors to observe and learn about birds.
Your support helps us to protect birds and wildlife—and their habitats—and to educate the conservation leaders of tomorrow.
Every visit supports research, and environmental education, and directly benefits the mission and success of Boyce Thompson Arboretum.
Guided bird walks are an ideal way to get into birding or to sharpen your skills! Join birding experts on scheduled walks from October through May. Beginners are welcome. No binoculars? No problem! Ask in our gift shop when you pay admission; loaner binoculars are available.

Collecting and directing stormwater is essential for a desert garden`s survival. If left unmanaged, pooling rain can damage plants and nearby buildings. Thanks to the generous support of Water Wise Arboretum donors, we now have several stormwater features around the Smith Greenhouses! It helps protect our historic buildings and guides the water to plants that need it most.
You can spot one of these water capture systems in front of the Smith Greenhouses. Arizona poppies are currently blooming inside, a living proof of its success!

The vibrant color on this caterpillar is a warning sign to any predators: do not eat!
The Pipevine Swallowtail feeds on Pipevine plants as larvae. Because Pipevine leaves are toxic to many animals, consuming them makes the caterpillars toxic as well. Their eating habits make the perfect defense mechanism!
This family of coatis has recently been spotted exploring the Canyon Region. We`re happy to report that in all our observations of them, they seem happy, healthy, and safe.
As a reminder, if you see coatis (or any wildlife) on the trails, keep a distance of at least 50 feet and refrain from giving them any food. They have plenty of delicious snacks growing right here at the Arboretum. By respecting their space, we can ensure safety for the coati, humans and pets enjoying nature.
And of course - if you take any photos, don`t forget to tag us so we can see them!
There`s nothing quite like walking through our hummingbird garden on a quiet summer morning. Flowers are in bloom, butterflies flutter across your path, and hummingbirds stop to sip nectar from nearby firecracker plants. It feels like walking through a magical portal that leads you deeper into the Arboretum.
When you visit us next, we hope you pause to really take in your surroundings. Observe the plant life growing around you and notice how the wildlife interacts with it. See what flowers are in bloom and notice their vibrant color. Let your curiosity guide you to the next wonder of the garden.
