In exchange for downloading the paper by Dwight Wynn and me, please consider supporting wildlife preservation in the Pantanal through the active efforts of the Rainforest Trust.   Copies of the book Paleofalconry have sold out through Amazon but you can contact me directly for a copy of the book in exchange for a direct contribution through the Rainforest Trust website or at one my demonstrations/programs.  Land acquisition and preservation of this type of ecosystem in its original form are critical for wildlife preservation.  In addition to Brazil and Bolivia, the Pantanal is in the Bahia Negra district in Paraguay (see accompanying graphic) an area of widespread concern where this ecosystem type and two others come together. The need for habitat preservation there is at its most pressing point.
