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.

  • 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

Fee $65 /Wednesday, Thursday 6:30am – 12noon 

This is a rare opportunity to visit the Arroyo Colorado Unit of Texas Parks and Wildlife Department. This Wildlife Management Area is closed to visitors, but we’ve arranged a special tour for the festival. In recent years, this area of thornscrub near the Arroyo Colorado has had a variety of rarities including Blue Bunting and Rose-throated Becard.
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 $95 / Wednesday, Friday 6:30am – 12:30pm

This is a unique opportunity for a small group to view some of the spoil islands of the 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 these islands. Participants will divide into two groups upon arrival at the dock. Each group will spend half their time on the boat and half their time on land, birding Adolph Thomae County Park and other nearby land-based sites. Expect a wide variety of birds on this eclectic trip.

Note: Although there will be photo opportunities, only hand-held cameras will be allowed on the boat segment. Restrooms are available at the dock. The half of your morning that will be on a small powerboat will be without restroom facilities. It can be cool on the boat – don’t forget your jacket and sunscreen.

Targets: Close views of herons and egrets, gulls and terns; with luck, the chance of spotting Mangrove Warbler.

*BAHIA GRANDE UNIT Van_1 Transit_1ScopeUseful_1

Fee $75 / Wednesday, Thursday 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.


Fee $65 / Wednesday, Friday, Sunday 6:30am – 12:30pm 
With its 760 acres of land and bird list of 358 species, it’s not surprising that this oldest of the South Texas state parks was chosen as the headquarters of the World Birding Center complex. The woodlands are home to many of the Valley’s specialties. The hawk-watch tower gives uninterrupted views of the skies, and the gardens surrounding the green-designed Visitor Center are a magnet for butterflies and hummingbirds.
Targets: Plain Chachalaca, Hook-billed Kite (rare), Gray Hawk, Green Kingfisher, White-tipped Dove, Buff-bellied Hummingbird, Golden-fronted Woodpecker, Northern Beardless-Tyrannulet, Green Jay, Clay-colored Thrush, Long-billed Thrasher, Olive Sparrow, Altamira Oriole.

UPPER RIO GRANDE bus_1 Transit_1_2h WC_1 LunchBox_1 ScopeUseful_1

Fee $90 / Thursday, Friday 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. Visit the birding places with the famous names: Salineño and Chapeño. The feeding station at Salineño is always a highlight with a colorful frenzy of orioles, kiskadees and Green Jays. In recent years a small number of White-collared Seedeaters have been present at Salineño, and we’ll look for these shy birds – now the only true tanager in the USA – in the reeds. If time allows we’ll stop at Starr County Park.
Targets: Muscovy Duck (rare), Scaled Quail (rare), Hook-billed Kite (rare), 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, White-collared Seedeater, Black-throated Sparrow, Pyrrhuloxia, Hooded, Altamira and Audubon’s Orioles.

WESLACO’S URBAN OASES Van_1 Transit_1_30 WC_1 LEPS_1

Fee $65 / 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. And with their wonderful mix of thornbrush, wetlands and butterfly gardens, they provide nesting habitat for many of our Valley specialties and a haven for wintering passerines. Conditions permitting, we will stop at a local sod farm on the way back.

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.
