Here in Houston @riceuniversity our soccer fields attract migrating meadowlarks in late October and early November. One might assume they are the expected Easterns but most have turned out to be Westerns. They r difficult to identify: subtle differences in face, tail and tertial patterns and vocals

This is well done.

To be fair, this isn't really a GPS antenna either. That is an antenna that someone sawed in half.

When a rare bird shows up, especially one as cool as a calliope, birders flock. @riceuniversity.bsky.social

#nokings San Diego Harbor today.

Allen’s Hummingbird @riceuniversity.bsky.social, our 274th species for this urban hotspot. Long overdue.

Nothing to see here, just delivering a dinosaur in Solana Beach .

Only one thing could top the honor of speaking at the No Kings rally, and that's the honor of speaking at No Kings 2. See you October 18th!

Not sure what's going on. This past week I discovered Red-footed Booby, Tropical Parula, and Western Wood-Pewee... and then today, an Allen's Hummingbird from California popped up on my morning walk to school. Houston, Texas. @riceuniversity.bsky.social

Here we go. We finally figured out where this bird disappears to. Red-footed Booby. One of very very few inland records of this seafaring bird. Houston, TX. Much better photos than yesterday's grainy shot of a flying bird from half a mile away.

In just a few days near Houston, Texas I found a red-footed booby, tropical Parula and a western wood-pewee, a truly bizarre and unlikely combination of birds.

New Paper! We investigate the first several months of postseismic motion following the M8.2 2021 Chignik earthquake on the Alaska subduction zone and how that motion can help improve our understanding of coseismc slip. ⚒️🧪 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

MTS/NCTD Free Ride Day is this Wednesday! Last year's increased MTS daily ridership by 15% and NCTD by 28%. I bet we can beat it this year. www.kpbs.org/news/quality...

Second step, eat 🍦 while walking home along the board walk.

First step, take my favorite 🚌 (30) to PB ice cream.

We found this amazing katydid in Honduras. Haemodiasma tessellata. Camouflage at its finest.

How about a coral snake up close? Foothill forests of the Caribbean slope in Honduras.

One of the most important and magical shorebird stopover sites in the country is the Bolivar Flats Bird Sanctuary in Texas. It is currently under threat from development and we are in a race to save it. houstonaudubon.org/conservation...

A storm blew over last evening in Houston, TX. This AM, at Rice University, I was surprised to see a Vermilion Flycatcher (rare for an urban environment). While looking at the flycatcher, I saw a dragonfly I had never seen before - Twelve-spotted Skimmer! The 2nd record for our county.

Grace's Warbler, a bird of mountain pine forests from southwestern United States south into northern Central America. This one I photographed in Honduras.

The Fulvous Owl, a bird of mountain forests in northern Central America. Always a magical feeling when one encounters an owl deep in the woods. This one we photographed in Honduras.

My favorite sign at the protest today, downtown San Diego

It's a small thing - but after 50 years of living in/visiting Pacific Beach, only this week did I learn why Missouri St is the outlier (Garnet, Diamond, Opal, Emerald, etc). Thx to watch.sdpb.org/video/ken-kr...

Lovely visitor to our deck this weekend. Figeater beetle.

I wouldn't even use the word design - academics don't like them either, but government agencies that should push for modernization decline to do so. The file formats are not only ancient but were designed way way way before real-time streaming was possible.

I’m afraid I would not be able to install and operate these GNSS systems anymore.

Why have the GNSS antenna below the solar panels?

Tulips in Keukenhof , the Netherlands

Always nice to be in a country that knows how to spell my name 😀

Earthquake!

I tested positive for TB in my teens, in SF, and was treated immediately. I’ve got nerve damage in my face because of it. If you think you may have been exposed, please try to get tested.
