The pileated woodpecker (Dryocopus pileatus) is the largest woodpecker in California and is unmistakable with its bold appearance and powerful presence. Though not commonly seen, it is often heard as it excavates large rectangular holes in tree trunks and downed wood while searching for insects.

This post is part of our Trailside Biology series, where volunteers from the Sugarloaf community highlight interesting organisms they encounter while hiking, exploring, and caring for the park. From flowers and fungi to wildlife and seasonal oddities, these observations offer a closer look at the living stories unfolding along our trails.

It's time for another installment of Trailside Biology! For our birding enthusiasts, this week we're talking about the American kestrel.

The American kestrel (Falco sparverius) is the smallest falcon in North America and can be found in open habitats like grasslands, meadows, and chaparral. These agile hunters capture prey by diving from a perch or by hovering in place, a unique behavior among falcons.

This post is part of our Trailside Biology series, where volunteers from the Sugarloaf community highlight interesting organisms they encounter while hiking, exploring, and caring for the park. From flowers and fungi to wildlife and seasonal oddities, these observations offer a closer look at the living stories unfolding along our trails.
