Two male slate-coloured juncos face each other in mid-flight, clasping feet like dancers as light snowflakes flutter around them in the snowy forest.

Two male slate coloured juncos hover facing each other in mid flight. The one on the left pulls his wings into an upstroke while bracing his tail, staring into the eyes on the one of the right who is mid-downstroke. Snow flutters around them in the snowy forest.

Some mid-air junco battles from the other day. They do these amazing, spiraling aerial battles. It's taken some practice to be quick enough to catch them. Most of my shots are of empty sky :) #birds 🌿

Wildlife needs your voice. Tell Congress: keep the Endangered Species Act strong. I signed—will you?

In honor of #EarthDay this week, speak out for the Endangered Species Act.

Help oppose U.S. legislation that would weaken protections, undermine science-based decisions, and make it harder to shield at-risk species from harm.

Low-Producing Oil Wells in Texas Cause Headaches for Landowners - Inside Climate News Jackie Chesnutt, who lives outside San Angelo, is tired of pollution from wells she says should have been plugged years ago. Experts say Texas rules allow companies to defer plugging wells for far too...
