Far off the west coast of Mexico lie Guadalupe and Socorro Islands. Even the names are unfamiliar to most people, and they are some the most rarely visited islands in the world. This unique voyage will visit the waters around them in search of the rare and endangered seabirds that breed only here and will offer one of the first ever chances to search out Townsend’s Shearwater, Townsend’s Storm Petrel, Ainley’s Storm Petrel and Guadalupe Murrelet. Many other interesting seabirds’ nest on these islands or feed in their offshore waters and we also hope to see Laysan Albatross, Scripp’s, and Craveri’s Murrelet, Ashy, Black and Least Storm Petrels, Black-vented Shearwater and many more besides. We should also see a range of other pelagic species including several whales and dolphins, the near endemic Guadalupe Fur Seal, and with luck, various sharks, turtles, and other marine life.

The islands of Guadalupe and Socorro also hold four endemic land bird species between them: Guadalupe Junco, Socorro Parakeet, Socorro Mockingbird and Socorro Wren. Permits are almost never issued to land ashore on the island, but we will be making every effort to obtain permits to seek out these species. If we are not able to land, we should be able to observe Socorro Wrens from skiff rides offshore.

The trip will be led by Adam Walleyn and Eric Antonio Martinez. Adam is one of the world’s most experienced seabirders and has extensive experience with almost all the world’s seabirds and marine mammals during over 1 000 days spent at sea. Eric is one of Mexico’s leading birders and has spent decades guiding birders to every corner of the country. The trip will be operated on the most comfortable vessel that visits these waters with a captain and crew that have made several previous visits.

What our clients say about us

David Hoddinott
GW & BW, Mexico 2022

David was brilliant, as usual, and the Mexican guides were also exceptional, making for a really good tour. Great country, fabulous birds, would like to go back.

David Hoddinott
JB & TB, Mexico 2022

Our trip, a long time in the waiting, was nothing short of a triumph. David led us again with passion, interest and focus. Jorge, our local guide. and his wife Amy who joined us were a triumph leading us to, and putting us on many many lifers. The travel arrangements were well made, the hotels were comfortable and the meals copious. Our first trip to Mexico will most certainly not be our last. Roll on the Yucatan!

Christopher Sharpe
PL, Mexico 2018

Our tour leaders produced a very successful tour. They worked together well and their skills complemented each other. Chris's education and experience provided us with a plethora of knowledge and fun facts. His personnel skills were put to the test with quite a diverse group of birders with an assortment of desires. He succeeded well. One could not ask for a better local guide than Eric. He knows every nook and cranny of his turf. He knows the birds well and multiple sites to look for each species. He has very good eyes and ears. But for me, his strongest characteristic is his genuine desire to find every target for the group. His persistence is unmatched. It paid off several times. I enjoyed the trip.

Adam Walleyn
GB & DB - Mexico 2022

"We are pleased to report on our recent Rockjumper birding adventure after spending four weeks (March 22 - April 17) exploring many of Mexico’s best birding sites during back-to-back trips to the states of Veracruz, Oaxaca and Chiapas. We were guided by Rockjumper’s Adam Walleyn and his local contact, Eric. Adam guided us in previous trips to Papua New Guinea, Madagascar, Cuba, Jamaica and Dominican Republic, and we have always been impressed by his worldwide birding expertise and his knowledge of, and enthusiasm for, all wildlife. Eric (a Mexican, living in Oaxaca, and fluent in English) has intimate knowledge of literally every bird species that resides in or migrates through Mexico - over 900 species. We slept well and ate extravagantly. Our drivers did an outstanding job of driving safely and minimizing the discomforts of numerous speed bumps and potholes. We birded in a diversity of landscapes that varied from sea level (during a morning coastal/pelagic cruise), to a mangrove forest, to desert scrub and to cloud forests where elevations were over 8000 feet. The highlight of our trip was, of course, the wildlife. We recorded a total of almost 500 bird species during the three trips - 20 of those were heard only. But with Eric’s guidance we had an exceptional opportunity to absorb Mexican culture. We visited ancient stone ruins, enjoyed delicious meals in small village homes (fincas) of farmers and coffee growers, and were pleased to view the products of skilled woodworkers and potters. Adam and Eric did their best to ensure that everyone in our diverse group saw every bird that we encountered. Everyday we were amazed by their skill in spotting and hearing birds and getting their scopes on the birds so that all could see. Their warmth and passion were felt and appreciated by all. We never felt threatened or insecure during our month-long trip. Mask wearing in Mexico is a law with near 100% compliance, including outdoors (our group complied when outside the van). We had no heath issues associated with food and drinks. "

Adam Walleyn
PC & GC, Mexico 2022

Adam Walleyn was an excellent guide, extremely knowledgeable, friendly and well organized. Our local guide is one of the best local guides I have known on a birding tour – intimately familiar with the birds of Mexico, their habits and habitats. Consequently we were successful in finding and seeing many of the challenging endemic birds of the Oaxaca and Huatulco areas.
