I didn't realize that small birds could be fairly long lived. Then I read the following website and learned that a male Spotted Towhee, like this one, was recaught and released in California was at least 11 years old at the time!

"•The oldest recorded Spotted Towhee was a male, at least 11 years old when recaught and rereleased during banding operations in California.
•Geographic Variation Nine subspecies show weak to moderate variation. The Oregonus subspecies is the darkest, evidently what we have in Oregon.
•Status and Distribution: Common. Some populations are largely resident; others are migratory. The most migratory subspecies is arcticus. Resident south to Guatemala. Subspecies are oregonus (Oregon to British Columbia), falcifer (coastal northwest California), megalonyx (coastal central to southern California), clementae (certain Channel Islands); arcticus (Great Plains), montanus (Rocky Mountains), falcinellus (south-central California to Oregon), curtatus (primarily in Sierra Nevada), and gaigei (resident in mountains of southeastern New Mexico and western Texas). Migration: fall primarily September–October; spring March–early May; earlier in Pacific states than interior. Vagrant: subspecies arcticus is casual to East."
