Carlos was an unbelievable bird-guide, extremely knowledgeable and quick to identify numerous species in seconds. Before the trip, he asked me if there were any species, in particular, I wanted to see, I told him I would like to see a Turquoise Browed Mot Mot: He planned the trip accordingly, and within 5 minutes of arriving at our first spot we found several turquoise browed motmots, along with tons of other species: Black-headed Trogons, Gartered Trogons, Scarlet Pigeon, several species of hummingbirds and orioles. Within the first half an hour of birding, we were already well over 30 species. We went to three different spots, all of which had different species of birds, he planned the trip so that we would be at each spot at the perfect time and maximize our species list for the day. Everything was extremely well planned and executed, I had never seen so many birds in one day before. We ended the day with 72 species, including several endemic species (Yucatan woodpecker, Yucatan Vireo, etc), 8 different species of orioles, 2 different species of Tucans, 2 species of Trogons, over 10 species of warblers and even ran into some spider monkeys!
Overall, I HIGHLY recommend booking a birding trip through Contoy Excursions, but more specifically, I advise requesting Carlos: I'm sure the other guides are great too, but Carlos made the experience unforgettable!
