First Hummingbird Nest of the Season

Anna's hummingbirds are year round residents in my yard. I usually notice a few nests each spring and sometimes the breed sometimes as early as December. Often the nests are in surprisingly exposed locations as in this case, perched where a bamboo stem meets and overlapping leaf from another stem. The location is just above a path and quite exposed to wind and rain. The nest here is in its second day of construction and I was able to observe the builder gathering moss and lichens on a nearby locust tree:

As a side note, the bamboo is Hibanobambusa tranquilans 'Shiroshima' and is beset by bamboo mites. The damage is visible as the blocky tan patches in the leaf in the lower left foreground.
