Just like the human snowbirds who are packing up their RVs to head south to Texas, short and medium-distance migratory birds are making similar, albeit simpler plans, anthropomorphically speaking. Using their internal GPS systems, birds will be searching for wintering habitats in Texas that provide food, water, and shelter.

Among the many species that winter here, like ducks, small falcons and native sparrows, are four species of wrens. They will start returning to Texas in October from northern states and Canadian provinces, especially as the month progresses. Three live in fairly specialized habitats, while one is a little more adaptable. All are well-camouflaged.

Sedge Wren – James Giroux

Sedge Wrens are small birds, about 4.5 inches long, that like to winter in grassy marshes and dry grassy fields. Although they rarely occur in Travis County, they have been attracted to the restored prairie at Commons Ford Ranch Metropolitan Park the last couple of winters. The Sedge Wren’s call and song are reminiscent of an old manual typewriter, with very dry chip notes, and rhythmic staccato chattering. They are more easily heard than seen, running on the ground to avoid predators, or flying a very short distance before diving back into cover.

Marsh Wren – James Giroux

The Marsh Wren favors wetlands that have cattails or other vegetation like sedges and bulrushes. In the winter they also use tidal saltmarshes along the coast, where the migrants join the population of resident Marsh Wrens. In Austin Marsh Wrens can be found in large ponds that have cattails, as well as along lakes with tall, emergent vegetation. The classic pose for Marsh Wrens is straddling two different plant stalks as the birds look around alertly, with tails cocked up. They are somewhat similar in appearance to Sedge Wrens, but are slightly larger with longer bills. Marsh Wrens sing a different tune too. Both Sedge and Marsh Wrens are secretive and require some effort to see.

Winter Wren – Jane Tillman

At only 4 inches, and favoring dark, wet woods especially along streams where it investigates nooks and crannies for insects and spiders, the Winter Wren is also hard to spot. Its chocolate-brown color and ridiculously short tail are helpful identification pointers. It doesn’t sing much, if at all, in winter, which is a shame since its songs are long, complex and memorable for such a small bird.

House Wren – James Giroux

The wintering wren that you are most likely to encounter is the House Wren. While still somewhat secretive, it favors areas with trees, shrubs and brushy tangles around more open areas. Less groomed park edges are a good place to look. House Wrens call attention to themselves with sounds like churrs, rattles, and chatter in winter, and will occasionally pop out to look for predators. They are drab, small, slender birds. Unlike our resident Bewick’s and Carolina Wrens, they don’t have white eyebrows. At least in their summer habitats, House Wrens are aptly named, as they are often found foraging and nesting close to houses. A fun fact about House Wrens is that they can live in a wide variety of habitats, from deciduous to coniferous forests and from swamps to mountainside elevations of 10,000 feet. When it comes time for House Wrens to migrate north for the summer, be sure to listen for their beautiful gurgling songs that run up and down the scale.

For many birds the securing of safe wintering habitat is more challenging every year as Texas becomes more and more developed. You can help them by planting native trees, shrubs and perennials that provide food and shelter. Visit the Lady Bird Johnson Wildflower Center’s semi-annual plant sale on October 18 (members only) and October 19 when open to the public. Learn more about native plants for birds and other wildlife by taking a Native Landscapes for Birds class from the Native Plant Society of Texas.

Travis Audubon October Events — Check the calendar. Events often fill quickly and some require registration.

Monthly Meeting October 17, 6:30 p.m. Location: First Unitarian Universalist Church at 4700 Grover. Robin Doughty and Matt Turner’s topic, “Unnatural Texas? The Invasive Species Dilemma,” will focus on invasive species in Texas and their effects on birds. 

Beginning Backyard Birding October 26, 9:00 a.m. to 1:15 p.m. at the Lady Bird Johnson Wildflower Center. Registration and fee required

Travis Audubon Field Trips —A great way to learn more about our central Texas birds is to go on a field trip. Check the website for other trips, and location and registration details.  Most trips are free and some provide loaner binoculars.

Beginners Bird Walk at Brushy Creek Lake Park October 5, 8:00 to 10:00 a.m. Get acquainted with local birds at this 90 acre park in Williamson County. No registration required.

The Commons Ford Big Sit October 13, 6:30 a.m. until dusk. The Big Sit is an annual, international birding event hosted by Bird Watcher’s Digest and sponsored by Swarovski Optik. It is more informally known as a “tailgate party for birders.” The object is to see how many species we can count in a 17-foot diameter circle within a 24-hour period. This is usually done while sitting, visiting with fellow birders, eating, drinking, and relaxing! It’s a really cool way to see how the bird activity changes throughout the day. Stay as little or as long as you like. Registration preferred but not required.

Hornsby Bend Monthly Bird Walk October 19, 7:30 until about 11 a.m.  Join us to explore Austin’s premier birding site. This event is sponsored monthly by the Hornsby Bend Bird Observatory. All levels of birders are welcome. Meet in front of the Center for Environmental Research.  No registration required.

Birdability Walk at Lake Creek Trail October 19, 8:00 a.m. -10:00 a.m. Meet at Lake Creek Trail, 9500 Braes Valley, in NW Austin not far from the US Highway 183/Anderson Mill intersection. This is a bird walk tailor-made for people with mobility challenges. Not only is it completely accessible with a level paved trail, but it has four different habitats that attract a number of beautiful birds. No registration required. See website for further directions. Compiled by Jane Tillman, Travis Audubon Volunteer
