James Gentz has seen birds aplenty on his East Texas rice-and-crawfish farm: snow geese and pintails, spoonbills and teal.

A tantalizing scent trail has been laid to lure an animal that can range over a thousand square kilometers to this precise spot, outside of the town of Fernie. Lamb’s colleague, wildlife technician Laura Smit, drizzles rotten cow blood through the woods from a red plastic gas can.
