Remarks:
This is how W. J. Schaldach Jr., acclaimed Tuxtlas birding authority now deceased, describes the island:
If the trip to visit Isla Terrón is possible today, ..... we will board our launch to run along the coast, passing
numerous basalt cliffs and headlands where Peregrine Falcons winter (Sept – early May) to arrive at Cape
Roca Partida (Split Rock). Just offshore from the cape (about 1 Km.) is the rocky island we are seeking, in
shallow water, surrounded by a coral reef. Here, on the rocks and low shrubs, five species of sea birds
rest: Brown Pelicans, Frigate Birds, Laughing Gulls, Royal Sandwich and Least Terns. During peak
migration periods, flocks of herons, anhingas, Franklins and Bonapartes Gulls, terns and passerines
(including enormous flights of Great – Tailed Grackles) pass over and around us (a glorious spectacle!).
The best times are the months of September and April. The species which nest here do so from March to
May, but the frigate birds and Brown Pelicans nest again from September to November in most years.
