When I think of flower stalks I think of the delicate stems of the wildflowers I’d see on hikes through most of my life, like daisies or columbine or fairly slippers. The soaptree yucca, on the other hand, has a towering stalk that’s thick at the base like a tree limb before tapering into thin branches at the top. Even so it is a testament to how impossibly light birds are that this bedraggled thrasher only slightly depressed its perch as it sang on a sunny winter morning.
