The RGVBF has long been renowned for its low ratio of participants to leaders and for the quality of its leaders. This year is no exception. On one of our field trips you might find yourself in the company of Jon Dunn or Kevin Karlson, or maybe Michael O’Brien or Neil Hayward, or perhaps Steve Shunk or Dave Irons. And the list doesn’t end there – just look at the biographies of our 80+ leaders.


      • Please stay in or near Harlingen during the Festival. Trips cannot be met at the sites.

      • Scopes and camera are fine on most trips. Icons just designate a better opportunity.

with Stephanie Bilodeau
Fee $85 / Friday 6:30am – 12:30pm

This is a wonderful opportunity for a small group to go out on the Bay with Stephanie Bilodeau to view some of the spoil islands of Laguna Madre. 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 and Estuaries Program, which has for many years studied and monitored the bird populations of the islands.
Note: Although there will be photo opportunities, please only bring hand-held cameras. Most of the morning will be on a small powerboat without restroom facilities. Can be cool on boat in mornings – don’t forget your jacket.
Targets: Close views of herons and egrets, gulls and terns and, with luck, Mangrove Warbler.

*BAHIA GRANDE (LAGUNA ATASCOSA NWR) Van_1 Transit_1ScopeUseful_1

Fee $60 / 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 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.

Targets: Waders, Shorebirds, Gulls and Terns, Aplomado Falcon, White-tailed Hawk, wintering sparrows.


Fee $60 / Saturday, 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 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.

Fee $90 / Wednesday 6am – 4:30pm
Ever hear about Big Days and wonder what they would be like? Here’s your chance to get in on the action on one of our most talked-about trips. Some call it ‘whirlbirding’–fast and furious fun. Prepare to be flexible, as routes will be chosen by your skilled leaders, exercise those speedy get-on-it skills – and wear your fast shoes!

*GOLD SERIES TOURS Van_1 Transit_1 Walk_1 WC_1

Fee $95 / Friday 6:30am – 1pm / Thursday, Saturday 7am – 1pm 

Every accomplished birder has his or her distinctive approach to birding and bird identification. It’s something that can’t be learned just from the books. It’s developed over years of experience of critical observation of birds in the field and absorbing information about them and their environment from a myriad of sources. The purpose of the Gold Series is to give Festival-goers a chance of short-cutting that process, at least a little, by experiencing time in the field in small groups with some of the leading birders of our day -including Jon Dunn (Peterson Field Guide to Warblers, Peterson Reference Guide to the Gulls of the Americas, National Geographic Field Guide to the Birds of North America and Birding Essentials) and Kevin Karlson & Dale Rosselet co-authors of Birding by Impression: A Different Approach to Knowing & Identifying Birds.

The tours are:

Thursday, Saturday – Estero Llano Grande State Park with Jon Dunn

Friday – Birding by Impression with Kevin Karlson and Dale Rosselet.

Goals: Developing a deeper understanding of birds and bird identification and honing field-craft skills.

Many birders have a special fondness for raptors, and judging by the number nesting in, migrating through or wintering in the Valley, raptors seem to have a similar feeling for the Valley. On this trip, led by Harlingen resident and world-authority raptor expert Bill Clark (Peterson Guide to Hawks, and A Photographic Guide to North American Raptors), we’ll try our best to see as wide a variety of species as possible in the time available.
Targets:  White-tailed Hawk, Hook-billed Kite (rare), Gray Hawk, Harris’s Hawk, Crested Caracara, Aplomado Falcon.

On this leisurely tour, we’ll visit two little 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.
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.
