…and also why it’s called “Broad-billed”.
Although those two statements concern two different birds.
Update: as of Friday morning, “Bill”, the Broad-billed hummingbird, is still reporting in to our backyard feeders, passing the 72-hour mark (I first observed him on Monday afternoon). We guess he’ll be here until he’s not!
Breeding season for Anna’s hummers is in full swing here in Phoenix. The males are executing their showy flights, shrieking down from a height with their gorgets flashing scarlet, making a loud peeping pop 
with their tail feathers like tiny bullroarers, then rising vertically upward to do it again and again, usually targeting a perched female to impress her with this routine.

And from my studio I’ve been watching a female Anna’s gathering spider webs and flying away with her beak wrapped in gossamer, a sure sign of “nidification,” otherwise known as nesting.
When our trees were trimmed last week, we searched hard beforehand to make sure there were no current nests in the trees affected, and didn’t find anything. However, late this afternoon, while scanning for the errant Broad-billed hummingbird who has been working our feeders, I did find a nest, just by luck: I saw the Hen fly up into a low pine branch, and stick. Binox showed me a little beaky head above an apparently completed nest, built above a pine cone on a nearly horizontal branch. From everyone’s perspective, it’s not a great spot: it’s fairly low over the path through the part of our yard we call the Sonoran Garden, and E could (and probably unintentionally will) bump the branch with his head as he walks by.
To me it seems a very exposed location. In fact, while I was watching her, the Broad-bill zoomed up and perched on a smaller branch just inches below the nest with hen, apparently unaware of her. She knew he was there: she froze, and waited perfectly still until he went away, which was soon — he’s a restless body.

The Broad-bill flew a short distance away and settled on a preferred perch in the “ugly” lemon tree. Although the photo isn’t perfectly sharp, you can see that the base of his bill is slightly flattened, making it look broad, especially in comparison with the needle-like rest-of-the-beak.
Incidentally, for the first time ever, the normally prolific “ugly” lemon tree set one whole lemon as its entire crop this season, and it dropped that during the tree-trimming episode. So as far as I’m concerned the shirking citrus can bear the burden of a tiny colorful bird as its tangy winter crop for a while longer.
Last fall our herb garden hosted a successful crop of parsley, cilantro, and Lady bird beetles (AKA Lady bugs). But we only noticed the bounty of bugs when we found roving hordes of hungry beetle larvæ voraciously devouring hapless aphids. Pictures of the process of larval metamorphosis were captured and posted here, but all the eggs had already hatched, leaving the beginning of the adventure undocumented. Now the cycle has begun again, and happily this time we caught it from the start.
