I was in costa rica last week on a convention and had the opportunity to go on a tour with Randall. I did not know what type of guide I would get, but boy was I impressed. I am a birder from the state of louisiana and have been on birdwatching tours in Costa Rica on 3 prior occasions. This was by far the best tour i have been on. I brought my Cannon 7D with a 400mm f5.6 lens. I am a hobby photographer and am still learning. Randall helped me with my photography setttings and we got some good photos of trogans(slaty tailed and black throated i believe), Motmots, toucans, scarlet macaws(on the highway leading to the park), several green and black poison dart frogs, great tinamou, boat billed flycathcers, a buffed rumped warbler, Northern woodcreedper, a white shouldered tanager, dot winged antwren,a green kingfisher white ibis and others. We also saw iguanas on the trail, collared pecararies, several jesus christ lizards, spiders and several species of butterflies. I was truly impressed with Randalls' knowledge and enthusiasm for what he does. He also identified several type of plants with medicinal qualities. The pace on this tour was very nice and relaxed. I would recommend this tour to anyone. It was the highlight of my visit. By the way, my youngest son, who is 22 years old, enjoyed it also. The other reviews i just looked at on this site are accurate. This guide is incredible.
