Home / Schedule / Trips













The RGVBF has long been known for its low ratio of participants to guides and for the quality of its leaders. Check out the Trip Leaders section for a summary of this year’s guides. We have an outstanding group of talent this year to guide our field trips, and several new destinations including new pre-festival and post-festival trip destinations. Also new this year is the Young Birders track plus a series of trips for mobility-challenged birders.

While we have kept the classic field trips that define our Festival, we have also added a few new locations, and a few twists on old favorites. Click on Schedule for a simple overview of the daily trips. Below is a more detailed daily description of the activities offered, with access to the specific information in each box.


  • Please stay in Harlingen during the Festival – trips leave early and cannot be met at the sites. Buses/vans do not wait for tardy birders.

  • For special trips for photographers, see the PhotoTrack section.

  • Vegetarian lunches available – choose when registering online.

  • Keep in mind that, with their limited seating, van trips tend to sell out quickly.

  • * Designates a special trip -new offering, distinctive leader or only conducted this year.

  • Be prepared for South Texas sun and bugs on all trips. Chiggers live here, so stay on paths when on field trips and avoid tall grasses. Bring appropriate remedies if chiggers love you.

  • Water and water bottles provided.

  • Check with driver to be sure your scope and tripod will fit on vans. On bus trips, tripods may need to be stored in luggage area of bus.

  • Hand-held cameras are fine on most trips; icons just designate a better opportunity.

  • Cameras with long lenses and tripods cannot be accommodated on van trips other than PhotoTrack. For special trips for photographers, see the PhotoTrack section.

  • Bus/van designation may change. We reserve the right to make adjustments as needed.

  • Check out the “Wondering Which Field Trip is Right for You” under FAQ for special interest trip recommendations.

*ARROYO COLORADO UNIT Transit_1_30WC_1Walk_1

with Anthony Henehan
Fee $85 /Wednesday, Thursday 6:30am – 12noon 

By special arrangement for the Festival, Wildlife Biologist Tony Henehan will take us on a tour of the closed Arroyo Colorado Unit of Texas Parks and Wildlife Department. In recent years, this area of thorn scrub habitat near the Arroyo Colorado has attracted a variety of rarities (including Blue Bunting and Rose-throated Becard). As it is an under-birded tract, the day’s list could be surprising.
Targets: White-tipped Dove, Golden-fronted and Ladder-backed Woodpecker, Great Kiskadee, Carolina Wren, Long-billed Thrasher, Orange-crowned Warbler, Olive Sparrow.


with Stephanie Bilodeau
Fee $110 / Wednesday, Friday 6:30am – 12:30pm

This is a wonderful opportunity for a small group to view some of the spoil islands of Laguna Madre Bay. The islands were created from materials dredged during the construction of the Intracoastal Waterway and, under the protection of the National Audubon Society, are now invaluable habitat for nesting, feeding and roosting waders, shorebirds and larids. Stephanie is the Conservation Biologist with the Coastal Bend Bays and Estuaries Program, which has for many years studied and monitored the bird populations of the islands. Our group will divide into two upon arrival at the dock and each group will spend half their time on the water and half their time on land birding Adolph Thomae County Park and surrounds.
Note: Hand-held cameras are appropriate for this boat trip. Restrooms at dock only – no facilities on the boat. It can be cool on the water– bring a jacket.
Targets: Close views of herons and egrets, gulls and terns and, with luck, Mangrove Warbler. .

*BAHIA GRANDE UNIT Van_1 Transit_1ScopeUseful_1

Fee $80 / Wednesday, Friday 6:30am – 12:30pm
The ongoing restoration of the Bahia Grande is the most significant environmental success in South Texas in recent years. Over 21,000 acres were acquired as part of Laguna Atascosa NWR in 2000. At that time, because construction of the Intracoastal Waterway had severed its connections to the Bay, Bahia Grande was an arid wasteland with only ephemeral wet areas. New channels have now been excavated, restoring the natural tidal flow. On this trip, we’ll have an opportunity of witnessing the dramatic results and the privilege of birding an area not generally open to the public.
Note: There are no on-site restroom facilities. We will have a restroom stop before and after our birding.
Targets: Herons, egrets, shorebirds, gulls and terns, Aplomado Falcon, White-tailed Hawk, wintering sparrows.


with Jon Dunn and Bob Powell
Fee $65 / Thursday 7am – 1:00pm

This trip back into history is a new first for the RGVBF! Did you know expert birder Jon Dunn is quite the history buff, and is passionate about the Civil War? Putting these two resources together – birds and battlefields – for Jon was the perfect combination. The Battle at Palmito Hill, contested more than a month AFTER Lee’s surrender to Grant, was the last battle of the Civil War. The Palo Alto Battlefield was where the first battle of the Mexican-American War was fought. Both these sites are in the coastal prairie with expansive vistas and, of course, the birds that love these open tracts. Learn about the history and significance of these geographic areas as you appreciate the prairie birds.

Important: We will be passing through a U.S. Border Patrol Check Station on Boca Chica Road. Make sure you have your driver’s license or other official photographic ID with you; participants without proper identification will not be permitted to board.
Targets: White-tailed Kite, Harris’s and White-tailed Hawks, Long-billed Curlew, Couch’s Kingbird, Curve-billed Thrasher, Chihuahuan Raven.

PARROTS OF THE AREAVan_1 PhotoOp_1 ScopeUseful_1

Fee $40 / Thursday, Friday, Saturday 4pm – 6pm

The Valley is home to several large flocks of Red-crowned Parrots – possibly more than are left in all of Mexico at this time.  As part of the Tejano Parrot Project, these flocks have been studied and tracked for two years now, to better understand their behavior and habits for conservation purposes.  The Harlingen flock, while predictable, is always a chase.  Join the search (we need everyone’s eyes and ears) as the parrots come in for their final feeding frenzy prior to roosting.  These countable parrots, noisy as they are, can instantly go quiet, once roosted.  The antics of the younger parrots can be quite entertaining. Come see why these colorful and personable parrots have captured our hearts and were again chosen as this year’s Giving Back Donation Project recipient.

Note:  Guides will not keep an official eBird list for this trip, so you can keep your own.

Targets: Red-crowned Parrot and Green Parakeet.  Watch for Red-lored and jumbo Yellow-headed Parrots in the mix (not ABA countable, yet).

The SPI Birding and Nature Center was built as the easternmost wing of the World Birding Center chain and has over 3300 feet of meandering board walk. The board walk offers 5 covered look-out stations as it spans salt and brackish marsh and lagoons and bisects thick Black Mangrove stands. This property frequently yields surprising sightings in addition to its delightful permanent residents. Rails can be quite accommodating, and the resident alligators are often visible on warm days. There are many opportunities for your point-and-shoot on this walk. Once we’ve completed the boardwalk loop at the Birding and Nature Center, we’ll make a stop at the notable Valley Land Fund lots on Sheepshead Street to see what might be present. Late fall has turned up a number of surprises here due to the concentrated habitat offered and the water features provided.
Targets:  Black-bellied Whistling-Duck, Redhead, Neotropic Cormorant, Reddish Egret, Roseate Spoonbill, Clapper Rail, Sora, Forster’s/Royal/Caspian/Sandwich Terns, Peregrine Falcon, Tropical Kingbird, Great Kiskadee, Scissor-tailed Flycatcher, Marsh Wren and more of the 235 species reported there in November!

UPPER RIO GRANDE bus_1 Transit_1_2h WC_1 LunchBox_1 ScopeUseful_1

Fee $100 / Thursday, Saturday 5am – 2pm

Luckily for us, birds don’t recognize our international borders. The river’s wooded edges and the arid uplands of Starr County are rich with both riparian sub-tropical and desert southwest species. The feeding station at Salineño is always a highlight with a colorful frenzy of orioles, kiskadees, and Green Jays!  Some rare specialty birds are found along the Rio Grande in this area, and we’ll certainly look, in hopes of seeing them. After we’ve enjoyed the beautiful view of the Rio, we’ll drive down the road to Falcon State Park, where we’ll look for desert specialties. Ideal for those Texas Century Club members building a Starr County list.

Targets: Gray Hawk, Zone-tailed Hawk (rare), Red-billed Pigeon (rare), Common Ground-Dove, White-tipped Dove, Greater Roadrunner, Green and Ringed Kingfishers, Cactus Wren, Verdin, Morelet’s (formerly White-collared) Seedeater (rare), Black-throated Sparrow, Pyrrhuloxia, Hooded (rare), Altamira and Audubon’s Orioles.


with Bill Clark
Fee $95/ Wednesday 6:30am – 4pm

Many birders have a special fondness for hawks.  Judging by the number of species nesting in, migrating through, or wintering in the Valley, raptors seem to have a similar feeling for the Valley.  On this special trip, led by Harlingen resident and world-renowned raptor expert Bill Clark (Peterson Guide to Hawks, A Photographic Guide to North American Raptors, Raptors of Central America), we’ll try our best to see as wide a variety of species as possible as we traverse the 5-county area.  Tips from Bill on hawk ID – priceless!

Targets: White-tailed Hawk, Hook-billed Kite (very rare in recent years), White-tailed Kite, Gray Hawk, Harris’s Hawk, Crested Caracara, Aplomado Falcon and any other hawk that crosses our path.

WESLACO’S URBAN OASES Van_1 Transit_1_30 WC_1 LEPS_1

Fee $85/ Wednesday, Saturday 7am – 1pm

On this leisurely tour, we’ll visit two urban gems in Weslaco – the 15 acres of Frontera Audubon Thicket and the 6 acres of the Valley Nature Center. But don’t be misled by their size – both have attracted an impressive array of Mexican vagrants, including a Crimson-collared Grosbeak found on a previous Festival tour. With their wonderful mix of thorn brush, wetlands and butterfly gardens, each provides nesting habitat for many of our Valley specialties and a haven for wintering passerines. Time and conditions permitting, we will stop at a local sod farm on our return trip.

Targets: Black-bellied Whistling-Duck, Plain Chachalaca, Common Ground-Dove, White-tipped Dove, Buff-bellied Hummingbird, Green Kingfisher, Golden-fronted Woodpecker, Tropical and Couch’s Kingbirds, Green Jay, Clay-colored Thrush, Long-billed and Curve-billed Thrashers, Olive Sparrow, Altamira Oriole, Lesser Goldfinch.
