Driving south from Houston, one encounters extensive agricultural production. Corn, cotton, grain sorghum, rice and local seasonal vegetables. Don’t forget about cattle! Texas leads the nation in production of cattle, sheep and goats. After about half an hour, traffic began to thin (most was heading north to jobs in the city) and the sunrise revealed a landscape familiar to these two Florida natives – really flat.
Our destination was the San Bernard National Wildlife Refuge. Established in 1969 specifically to provide shelter for migrating songbirds, it sounded like our kind of place. Bordered on the south by the Gulf of Mexico, the refuge consists of vast salt marshes, two rivers feed freshwater marshes, man-made impoundments provide protected spots for tens of thousands of waterfowl and there is even a section of old-growth hardwood forest to explore.
We typically spend our driving time talking to each other. (I know, right? But it’s only been 51 years so we may run out of things to say some day. Not.) Today’s topic centered on our son and his family. Their daughter is ten and we really enjoyed seeing her perform in a school play. Her brother is eight and full of mischief, exactly as a boy of eight should be. We couldn’t believe how much they had grown physically and socially since our last visit. It was a lot of fun watching the two of them interact with friends after the play had ended. We normally only see them in a home setting and this was different! They were both so full of energy and you could tell they are – happy. So were we.
Alas, we missed songbird migration by a week or so. Fortunately, we had a thoroughly enjoyable day poking around the refuge. We knew it would be a good day when we stopped at the entrance kiosk for a brochure and a Carolina Wren flew out of one of the empty map boxes where we found a perfectly formed nest. We retreated and hoped the wren would return.
A few images below may indicate the diversity to be found at this refuge. They are still in a bit of a re-building mode due to significant damage as a result of Hurricane Harvey in 2017. We look forward to a return visit and will try to adjust our timing a bit so we can see trees full of colorful warblers and thousands of ducks!
Entering the refuge.
In Florida, it is uncommon to spot a White-faced Ibis but Glossy Ibis are extremely common. This situation is reversed at San Bernard NWR. In breeding plumage, the White-faced Ibis has a white border around a reddish face, a gray bill, red legs and a red iris. The Glossy has pale lines around a dark face, the bill is more brownish and the eyes dark. (The image of the Glossy Ibis is from Florida.)
Black-necked Stilts nest in the refuge and we spotted more than a dozen during the day.
A lone tree in the salt marsh is the only notable break in the grass between us and the Gulf of Mexico.
Stand silently and observe the marsh for a few minutes and an incredible array of life becomes evident. Here, a flock of Snowy Egrets moves from one spot of open water to another.
We are always amazed at the size of the Purple Gallinule’s feet! Very helpful when walking atop aquatic plants.
This immature White Ibis will gradually molt into the all-white plumage of an adult.
Crested Caracara won’t hesitate to prey on waterfowl (or anything else that moves) but is equally happy to feed upon carrion.
Darting among reeds along a pond shoreline, the Common Yellowthroat male is not exactly camouflaged. During breeding season the male sings for what seems to be 24 hours a day.
It’s a bit unusual to catch a Sora fully exposed, as they tend to skulk further back in the weeds. I lay on my stomach and inched close enough for a few shots.
While laying in the grass taking photos of the Sora, I counted ten very young (12-18 inches) alligators run into the water ahead of me. Number 11 remained behind and let me know he was unafraid. I began to wonder where Mama was. Seemed like a good time to return to the path. Quickly. Looking over my shoulder.
On one of the impoundments constructed for wintering waterfowl, a Pied-billed Grebe paused for a candid portrait before returning to his fishing.
During breeding season, the Little Blue Heron’s eyes and legs turn black and the base of the bill becomes bright blue.
Flocks of Fulvous Whistling-Ducks could be seen all across the impoundments as they moved from one open water area to another. (Two immature Little Blue Herons are in the foreground.)
A pair of Black-bellied Whistling-Ducks watched their fulvous cousins from atop a nearby berm.
We even found a few flowers in bloom. A showy orange Lantana and bright red Tropical Sage.
In a muddy area, we were tempted to follow this alligator track to see where it went. Okay, Gini wasn’t thrilled with the idea. Okay, we both jumped in the car and locked the doors and sped away. There, satisfied?
Birds aren’t the only migrants which take advantage of the refuge. A Monarch butterfly almost blends in with the wildflowers.

Along a canal in the marsh, we came upon two very mature American Alligators announcing their territory. They were about 20 yards apart and quite loud. The water droplets “dance” above the alligator’s back due to sub-audible vibrations which precede the audible bellowing. Recent research indicates an alligator’s size can be determined by its bellowing characteristics. This allows a potential adversary to determine if a fight for territory or a mate is feasible. (Alligator’s Bellow Communicates Size.)
Despite all that bellowing not far away, this Black-necked Stilt just had to get a little power nap.
Speaking of naps, it was time for us to head to Houston. After a satisfying bit of Texas Bar-B-Que, we made it back and began packing for our return to Florida. It was a great visit!
If you get a chance to go coastal in Texas, drop by San Bernard NWR. Watch out for the wren’s nest at the entrance and respect the alligator’s territory – or test your own bellowing and see if you measure up.
Enjoy your search for a natural place and come back for a visit!
