Zoology: Saving Punta San Juan

For nearly a decade, Brookfield Zoo and its parent, the Chicago Zoological Society, have been sending researchers headed by veterinarian Dr. Michael Adkesson to Punta San Juan in Peru. 

Called Peru's Galapagos by some, Punta San Juan is one of the world's richest marine ecosystems, a place that offers a staggering, rare concentration of species in a landscape of dry cliffs bordered by the Pacific Ocean. It's also a 133-acre coastal reserve that has become a central part of Dr. Adkesson's life and a crucial piece in the mission of the Chicago Zoological Society to spread conservation awareness internationally.  

During the annual trips to Punta San Juan Dr. Adkesson and his team assess the health of fur seals, sea lions and a variety of seabirds and penguins. The institution also has broader goals of making Punta San Juan a model for 32 similar sites in Peru and, eventually, a global model for responsible marine wildlife management.

  • Dr. Matt Allender, a veterinarian and clinical assistant professor at University of Illinois at Urbana-Champaign, opened the main gates to the Punta San Juan coastal reserve. The reserve is on a peninsula which was walled off in the 1940s to protect the spot for harvesting guano from the nesting shorebirds to be used as fertilizer.
  • A group of Humboldt penguins stood on the beach together at the Punta San Juan coastal reserve. About 6,000 of Peru's 25,000 endangered Humboldt penguins reside at Punta San Juan, where they have been known gather in clusters of 100 or more.

  • A team of animal care professionals from several organizations including the Brookfield Zoo and St. Louis Zoo used wooden poles to fend off an aggressive Peruvian fur seal as they work to sedate others in the colony.
  • A South American sea lion laid sedated with a tranquilizer dart after he was shot by Dr. Adkesson. The dart took about 10 minutes to take effect, so Dr. Adkesson must also carry a second gun containing a reversal dart to shoot the animal should it make it to the water and risk drowning before becoming sedated.
  • Dr. Adkesson and his team including MaryAnn Duda, a veterinary technician for the Brookfield Zoo, right, worked to collect body samples and measurements on a tranquilized South American sea lion. The team of eight people collected blood, urine, fur, and blubber samples for study and also checked the animal's eyes, heart rate, and weight before measuring and tagging its' fins.
  • A South American sea lion with satellite transmitter glued to his head peered back to the beach as he headed towards the water follwing a medical check. The transmitter collects data on the animal's location, depth, and speed, as well as the temperature of the surrounding water, and transmits it back to a satellite in nearly real time.
  • Susana Cardenas, the director of the Punta San Juan Program, carried a Peruvian fur seal pup to be weighed. Cardenas first came to Punta San Juan as a student in 2003, then worked as a research assistant there before she left in 2008 to work on her master's degree in zoology at University of British Columbia in Vancouver. In 2011 the Chicago Zoological Society hired her as its Peru representative.
  • A team of animal care professionals from several organizations including the Brookfield Zoo and St. Louis Zoo packed up after a day of tranquilizing and taking samples from Peruvian fur seals.
  • After a day in the field Dr. Adkesson and Dr. Jenny Meegan, a veterinarian at National Marine Mammal Foundation in San Diego, worked to organize samples at the house in town that serves as their lab.
  • Broken bottles served as a deterrent for those considering scaling the wall at the Punta San Juan coastal reserve. While the wall has protected the area and its animal inhabitants from outside threats, it's also alienated the reserve from the local community members, many of whom have never been inside.
  • Miluska Elguera greeted students as they file into their classroom at Ricardo Palma School in San Juan de Marcona, Peru. The students are part of an outreach program with Punta San Juan where Elguera comes occasionally to educate them and spread awareness about the reserve.
  • Local merchants sold souvenirs of pelicans, penguins, seals and sea lions at a small stand in San Juan de Marcona, Peru. Primiarly a mining area, Marcona has seen a recent influx of tourism, driven in large part by the Punta San Juan reserve and its wildlife.
