William J Schaldach Jr. was one of the pioneers of wildlife study and specifically ornithology in Los Tuxtlas, Veracruz, Mexico. He died before publishing any of his thousands of fragments of historical lore in readable form. His last effort to annotate the birds of Veracruz died with him, but remains in a provisional form on the tuxtlas.com website.
A new addition to the knowledge of the birds of Veracruz is a simplified check list which should become a backpack item for any birder visiting beautiful downtown Catemaco and Los Tuxtlas, because most of the birds represented in the list, are also present in Los Tuxtlas.
