A chickadee couple has joined the titmouse outside the study window. This one is on one of the iochromas. Peterson’s Field Guide to Western Birds says that “the cap, bib, and white cheeks identify it as a chickadee,” while the chestnut back identifies the particular species of chickadee. Both the Peterson and the Audubon guides say it prefers moist habitats, such as Northwest rain forests. As it has rained here most days in January and February this year, I guess the chickadees have determined our drought is over.
