53. Boyce-Thompson Arboretum State Park, Superior, Arizona

The best migrant trap in central Arizona attracts hummingbirds, wrens, warblers, Summer Tanager, Lawrence's Goldfinch, and other birds.
By Jim Burns | Published: 10/22/2008

Boyce-Thompson Arboretum, “BTA” to state birders, showcases a collection of 3,200 plants from deserts around the world, including Sonoran Desert vegetation native to central Arizona. Combine this greenery with the riparian areas along Queen Creek, a small man-made lake, flowers in the Hummingbird-Butterfly Garden, and fruiting trees in the Herb Garden, and you have a wide diversity of habitats for birds.

Although the arboretum has a long-standing and well-deserved reputation as the best migrant and vagrant trap in central Arizona, winter may well be the best time to visit: Seven species of wrens are possible (Winter Wren is the prize); large, mixed flocks of sparrows are guaranteed (can you find the White-throated and Fox Sparrows among all the White-crowneds?); and each winter brings invasions from somewhere – Arizona’s mountains (Clark’s Nutcracker), the Pacific Northwest (Varied Thrush), or the East (Northern Parula).

In the spring, hummingbirds are everywhere, including Broad-billed, a recent addition, and for the past year BTA has hosted a spectacular, second-ever record Broad-billed x Violet-crowned hybrid. — Jim Burns
