After arriving in Tucson by midday, we will have time to make a trip up to Agua Caliente Park on the northeast side of the metro area. This park features a pond with surrounding cattail marsh, open woodlands, brushy tracts and thorn scrub desert. Consequently, species of many different habitats may be found in a relatively small area. Rufous-crowned Sparrow and Vermilion Flycatcher are found in the open areas of the park, while Bell’s Vireo, Pyrrhuloxia and Phainopepla prefer the brushy scrub. In the surrounding desert, Gambel’s Quail, Curve-billed Thrasher and Verdin work the mesquite and acacia.
