Of course, seasons in the southern Arizona/Sonoran desert aren't quite like those in more temperate climes. We've had winter; maybe we're still having it. The garden shows the effects of a week of overnight temperatures in the low 20s the second week in January with quite a bit of die-back on things that will recover, like cassia, purple heart, and some other perennials, and some that won't, such as wild poinsettia (which has, however, probably reseeded itself), sweet potato vine, and nasturtiums.
The goldfinches went away, but other birds stay year-round, like Mr. Costa, who feeds on the other side of our kitchen window (his real name is Costa's hummingbird; we've gotten quite well acquainted but I still like to address him with respect).
Verdins also like hummingbird feeders; we saw one yesterday morning, the first in more than a year. They are among my very favorite birds, so tiny, fluffy, and colorful with their yellow heads and red epaulets.
It's hard to know what season it is from one day - sometimes one hour - to the next lately. This morning when we took our walk it was definitely winter. This female phainopepla with her feathers fluffed out for insulation, on bare branches against a gray sky, perfectly captures the feeling. She's there in the same spot every morning, surveying her territory, I guess, and trying to stay warm.
