Birded here 26 November. Just walk around the tracks to the Cenote and back. Saw Great Kiskadee, Orange Oriole, Gray Catbird, Tropical Kingbird, Northern Waterthrush, Plain Chachalaca, Masked Tityra, Yucatan Vireo, Collared Aracari, Altamira Oriole, Hooded Warbler, Sqirrel Cuckoo and Yellow throated Vireo. It was early afternoon and obviously not the best time for birding. Had just been to the ruins at Muyil and down through woodland, then mangroves to top part of Sian Ka’an Reserve which should throw up a better range of birds and well worth a visit.
