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...

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

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.

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.

Lunar eclipse tonight, S of Bonn, Germany. Best part was to see how many parents with children came out and patiently waited to observe!
