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.
