Naturalist Notes

Allen's Hummingbird

Allen's Hummingbird

To attract mates, these little guys put on a quite show in spring–swooping, climbing, and diving, making a squeal with their tails. Look for a copper-colored throat and belly, with a bronze-green back. Selasphorus sasin can be found in forest, scrub, and chaparral along the coast from California to Oregon. Put up a feeder and you might attract them to your yard. Learn more at All About Birds.

Creekside Restoration

Marin County Parks and One Tam are enriching important habitat areas at Hal Brown Park and Creekside Marsh. This community-based effort is installing a diverse palette of native plants at a site once dominated by invasive grasses and weeds. This is just one of many opportunities for volunteers to help support thriving and beautiful ecosystems in Marin County parks and preserves.
