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.

  • Always refer to this website for latest trip updates.

  • Friend us on FACEBOOK to keep up with latest announcements.

with Tony Henehan
Fee $90 /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.

Common Ground-Dove, White-tipped Dove, Golden-fronted and Ladder-backed Woodpecker, Great Kiskadee, Carolina Wren, Long-billed and Curved-billed Thrasher, Olive Sparrow, wintering warblers.



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. Participants will divide into two groups upon arrival at the dock and each group will spend half their time on the water and half their time on land, birding the trees, bushes and beachscapes of Adolph Thomae County Park.

 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.

Close views of herons and egrets, gulls and terns and, with luck, Mangrove Warbler.  The park can hold plenty of migrant and resident passerines.

Fee $85 / Wednesday, Thursday, Saturday 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 to witness the dramatic results and the privilege of birding an area not generally open to the public.

There are no restroom facilities on the Bahia Grande Unit. We plan a restroom stop before and after our birding.

Herons, egrets, shorebirds, gulls and terns, Aplomado Falcon, White-tailed Hawk, wintering sparrows.



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

Join us on a trip back in history!  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! Bring photo ID or passport. There is a U.S. Border Patrol Check Station on this route. Make sure you have your driver’s license or other official photographic ID with you; participants without proper identification will not be permitted to participate.  

Targets:White-tailed Kite, Harris’s and White-tailed Hawks, Long-billed Curlew, Couch’s Kingbird Curve-billed Thrasher, Grasshopper Sparrow.

with Ted Floyd
Fee $100 / Saturday, Sunday 7:00am – 1:00pm

In this field workshop, Ted will demonstrate examples of birding in an electronic age, expanding on his Thursday presentation.  He will be sharing tips on eBirding, recording birds in the field, and more.  In addition to seeing lots of great birds, we’ll interpret what we’re seeing with digital resources like eBird, iNaturalist, small cameras, and pocket recorders. In other words, we’ll stop and smell the flowers–take pictures of them and even upload them to global databases. This trip will visit the private Cactus Creek Ranch, located in the coastal prairie near Rio Hondo.  Cactus Creek Ranch hosts ongoing research projects on wildlife, including Texas Tortoise and the oldest documented Black-crested Titmouse.

Goals:  Putting into practice Ted’s concepts on how digital age tools can make birding even more enjoyable.  The smartphone in your pocket can be the gateway to all your in-the-field questions.

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 three 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 a 2019 Giving Back Donation Project recipient.

Note:  Guides will be focused on finding the parrot flocks and 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 Birding and Nature Center was built as a wing of the World Birding Center and has over 3300 feet of board walk!  The board walk spans salt and brackish marsh and lagoons, and often yields surprising sightings – rails can be quite accommodating.  After we have checked out the native gardens on site, we’ll make a stop at Valley Land Fund’s Sheepshead lots to see what might be present at the water features.  Late fall has turned up a number of surprises.

Targets: Black-bellied Whistling-Duck, Redhead, Least Bittern, Neotropic Cormorant, Reddish Egret, Roseate Spoonbill, Clapper Rail, Sora, Royal Tern, Peregrine Falcon, Tropical Kingbird, Great Kiskadee, Scissor-tailed Flycatcher, Marsh Wren and a long list more.

Always a popular trip, so sign up early.

Luckily for us, birds don’t recognize our international borders. The Rio Grande’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, Great 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 up 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 Seedeater (rare), Black-throated Sparrow, Pyrrhuloxia, Hooded (rare), Altamira and Audubon’s Orioles.

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 raptor that crosses our path.

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.
