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

To be fair, this isn't really a GPS antenna either. That is an antenna that someone sawed in half.
When you see photos of GPS stations, you’re usually looking at the protective radome cover and not the GPS antenna itself. The gray radome helps shield the antenna from rain, snow, and debris buildup and protects it against general wear.

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/...

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.
