The #1 movie when you were 10 years old is how your 2026 is going to go.

Bird knowers of Bluesky, anyone have thoughts on an ID for this? Maybe Gray Vireo or Plumbeous Vireo? I'm mostly guessing, though. I saw it in the Catalina foothills north of Tucson.

A small gray bird perches on a branch, surrounded by small spiky branches which partly obscure it. The bird has a distinctive white ring around its black-colored eye.

Starbucks workers are still on strike so we're still posting #birds. Post a bird to remind your followers to buy from a local coffee shop for the duration of the strike. This broad-billed hummingbird supports Presta Coffee.

Apparently Starbucks workers are still on strike, so here's another bird to remind you to buy from a different coffee shop for the duration of the strike. This Gila woodpecker supports Yellow Brick Coffee. 🪶
A woodpecker with a brown body and black-and-white striped wings perching on the open blossom of a saguaro cactus. The bird's face is covered in pollen because it just pulled its head out of the flower.

Post a bird to support @sbworkersunited.org and remind your followers not to buy Starbucks during the strike 🪶

(If you live in medium sized town, or anywhere with a college or university, there's probably a great independent coffee shop near you. This phainopepla supports Exo Roast Co.)

The look on my face really doesn't indicate how smoked I was here. Haven't done this ride in a few years and forgot how tough the switchbacks are. Beautiful day for a ride, though.

(Doing this 18 hours after donating blood probably didn't help either, oops)

Planted sunflowers on a lark because I had a couple empty pots and I'm very happy I did!

A tiny sentinel

#birds
A male Anna's hummingbird, photographed in profile with its beak pointing to the right, perched on the copper wire supporting a hummingbird feeder. The bird is in the shade, so its gorget appears dark instead of shining bright red as it would in the sun.

It's saguaro fruit season, and I'm clearly not the only one excited about that #birds
A small brown bird (perhaps some kind of finch) perching on a saguaro cactus, with its entire head stuck inside a bright red fruit that has split open. Another split open fruit sits to the right of the bird. Photograph taken in Tucson, Arizona

This might be the new gnarliest object I've pulled from my bike tire.

The real surprise is that I apparently *rode home* without noticing anything wrong for... somewhere between 0 and 3 miles?

Limoncello with whole calamondins from the U of A campus, ready to go in the freezer today -- just in time for highs to swing back towards 100F here.
A half gallon mason jar filled almost to the brim with a hazy orange liquid, sitting on a faux granite kitchen counter. There are several small orange-colored citrus fruits (calamondins) floating at the top of the jar, and it's possible to see some lemon peels through the haze at the bottom of the jar.

Absolutely covered in pollen #birds
A male Gila woodpecker perching on a saguaro cactus flower, peering into the opening of a bloom with the red spot on the top of its head visible. The bird's face is covered in a dusting of pollen from having stuck its head into an adjacent bloom.
