At Isabella Lee Natural Preserve, I saw five Lucy’s warbler triangle-shaped nestboxes at 1, 3, 5, 7, 9 feet above the ground on a tree. Tucson Audubon set these up to find out which nest box the birds prefer since they ordinarily nest in woodpecker holes or bark crevices of old mesquite trees. Those trees are often removed for their valuable wood so this project is to encourage the Lucy’s warblers to remain in the Tucson area, especially if they do not find the tree of their choice.

I saw no activity in any of the nestboxes today; however, there were numerous hummingbirds, a couple of vermillion flycatchers, a red-tailed hawk flying overhead and signs of horses being through the area. This was my first time at the preserve which encompasses the confluence of Agua Caliente Wash and Tanque Verde Creek. Expect to see snakes, javelina, coyote and wildlife since it is a wildlife area also for them.
