Adenanthos sericeus

The woolly bush is a shrub native to the south coast of Western Australia. We planted three here in 2017; one eventually died but the other two are doing well. This fine-textured, upright shrub or small tree typically reaches a height of 6 to 10 feet. The wispy stems are adorned with soft, gray, needle-like foliage that feels velvety to the touch and displays pink hues in its new growth. Small red flowers emerge intermittently throughout the year at the base of the leaves. They are so obscure that I wasn’t even aware the bushes were currently flowering until I noticed the hummingbirds having a feast.

The rock wren (Salpinctes obsoletus) is a small songbird native to western North America, Mexico and Central America. They are apparently common and widespread, but this was the first time I’d ever noticed one.

I’ve learned that rock wrens usually build their nests in crevices among boulders or beneath large rock ledges, typically on the ground or just a few inches above it, resting on a foundation of small rocks. Uniquely, they create a “paving” or “front porch” at the entrance of the nesting site, often lined with small stones, bones, and various debris. The purpose of this “paving” remains a mystery, but it is evidently significant, as rock wrens construct it before building the nest itself.

The other fun sighting on this hike was a bobcat, calmly crossing the trail quite close to humans. I’ve seen these gorgeous cats in the same area of the Park on several other occasions; they are clearly habituated to hikers.
