Peter Crawshaw uses a hollow gourd ("esturrador" in Portuguese) to mimic the sound of a jaguar, Pantanal, Mato Grosso do Sul, Brazil. The purpose of using a jaguar caller is to invoke a response from jaguars that may be in the area. This can help researchers estimate population size. The images of Peter Crawshaw were made using red light which did not affect our night vision. I then transformed the images into black and white. This expedition was made possible through support from Mitsubishi and local ranch owners associated with the "Onças do Rio Negro" project.
