About Us


Sergio H. Seipke



Sergio started watching birds in Eldorado, Argentina in September 1992, but three months later decided to devote all his birding time to raptors only.  In 2005 Sergio became a Hawk Mountain Sanctuary International Intern and officially started working on the Raptors of South America project with support from Hawk Mountain.  Sergio enjoys helping others to find and identify raptors in the field.  He traveled to several Central and South American countries to observe and photograph raptors, and spent time in the field with raptor experts such as Bill Clark, Jean-Marc Thiollay, Russell Thorstrom, and Keith Bildstein from whom Sergio learned vast amounts about raptor identification and biology.  Sergio currently lives in City Bell, Buenos Aires with his wife Juliana, and their little boy Sean.



Frederick Pallinger



Brazilian graphic designer, falconer, and raptor captive breeder Frederick Pallinger started painting raptors with watercolors in 1992.  He decided to experiment with computer programs a few years later “because classic techniques were too time consuming and were not flexible enough”.  Freddy creates his artwork 100% in Photoshop -stroke by stroke- with his virtual brush.  He works at home in Sorocaba, Sao Paulo, Brazil, where he lives with his wife Mariana and their little boy Nicholas.  Freddy’s plates are inspired on actual photographs to ensure accuracy in coloration, pattern and proportions.



Darío H. Podestá



Nature photographer and biologist Darío Podestá started taking photographs in 1985 in his hometown Zapala, Neuquen province, Argentina.  Darío works closely with the author to make sure that raptor photographs are taken at the right angles to maximize identification information.  Darío has taken literally tens of thousands raptor photographs for this project and many of them will be included in the book.  But most importantly, Darío provides much of the ‘raw material’ that Freddy uses to produce his breath-taking, hyper-realistic plates.  Darío currently lives with his wife Ana and their little girl Anita in Puerto Madryn, Chubut, Argentina.
