You've just died. The 6th picture in your gallery is what killed you.

...Have I died by Wordle or bad dough??

Ash and Amber sleeping in a 1-cat bed. This didn't last very long.

Greetings from Ash and Amber, who think they can share this cat bed

(They totally had a fight about it after I took the pic)

If you see this post a flower 💐

A chaste tree, supposedly. Attracting an awful lot of bees 🐝

Went for a hike on Mt. Lemmon yesterday and there were so many birds I've never seen before!

Coincidence or...🤔

Got quite the #10minmerlin today!

First time it found a Cassin's finch and a Pyrrhuloxia, but not sure if those were real #tucson #arizona #birds

Agreed, and here I am, just a scientist saying that no matter what I am allowed to say about climate change, the soil will have its say. 🪱 ⚒️ 🌱

Didn't manage a #10minmerlin but rather amazed at the diversity of #birds detected in just 3 minutes! #merlin #tucson #arizona

Don't thank me @bsky.app, thank Musky for turning the bird app into a stinking cesspool of hate

My publication cloud is predictably all about #biochar and #soil!

Made latkes for the goyim in-laws today (yes on Christmas!)

If you were visited by 3 ghosts on Christmas Eve, who would you want them to be?

Hopefully just a student with an axe to grind...Ash and Amber say take it easy and with many grains of salt!
