Habitats will include montane, riparian, and pine forest. A wide variety of mountain birds will be seen (many at their nests). Bring water, snacks, and lunch. Walking will be on easy trails, so light boots or sneakers will be fine.

The hike will be easy but uneven, and only one or two miles total, with some driving
from place to place. Bring sturdy walking shoes to protect ankles (due to cactus). Spotting scopes optional (in case of raptors).
Expected species include McCown's Longspur, Lark Bunting, & Horned Lark. Species
that are possible (but not guaranteed) include Burrowing Owl, Mountain Plover, Ferruginous
Hawk, & Chestnut-collared Longspur.
