A sun halo that showed up over the desert sky earlier this week. Fine ice crystals in the cirrus clouds create this phenomenon. These cliffs are of the La Barge Box in the Superstition Mountains of Arizona.

I love these birds- that and they are also songbirds. Here is a picture of one I took where I stalked it for hours to photograph it.

I came across this petroglyph yesterday in an undisclosed canyon in Arizona. Those feet make me think grizzly bear. What do you think?

AZPS President-elect Chris Olson has told his dog Dogberry that people who don’t attend the AZPS annual meeting (Oct 17-18) will have a “significant physiology knowledge gap” compared to those who attend the meeting. Register at AZPS.life @azphysiology.bsky.social bsky.app/profile/cnn....

The Arizona Physiological Society annual meeting will be held at UofA Phoenix on Oct 17-18. This is a fabulous student-focused meeting for anyone in the Southwest who does any physiology-related research. @azphysiology.bsky.social #🧪
This is the official flier for the AZPS meeting.

Blergh! After a trip to Washington State for work, I came home and quickly came down with Covid. My symptoms are very mild, but it like it’s part of a growing trend.

These vagabond house sparrows, clinging to the margins of humanity with their matted feathers and crusty beaks. Some say they should not be here. Yet their persistence in this world is one of beauty. #birds #🪶
