Hola! We are back in the farming village of Mastatal, Costa Rica after a whirlwind visit to the Pacific coast. We spent some days at Hacienda Baru, a private nature reserve near Dominical, where the class explored the mangroves and other coastal habitats with staff naturalists. We also spent time with naturalists in Manuel Antonio Natural Park as well as some mangrove islands further north - all teeming with monkeys, sloths, and other wildlife. Finally, we had the opportunity to participate in night beach patrols, looking for nesting sea turtles - several groups had the good fortune of witnessing the ancient ritual of Olive Ridleys crawling up onto the beach in the dead of night and laying their eggs!
