Red-capped Manakin (Ceratopipra mentalis) by Alan Dahl


Alan lives in Northern California and maintains a full time job in the software industry to fund his obsession for nature and wildlife photography. He loves the biodiversity that the Osa Peninsula has to offer and has traveled there to photograph wildlife numerous times.  In fact, he has yet to go anywhere else in Costa Rica.  “A place as wonderful as the Osa Peninsula must be preserved for future generations”.

Alan has generously contributed many of his photographs to Osa Birds website in our mission to conserve birds on the Osa of which we remain extremely grateful.

Alan has generously offered to donate 50% of the proceeds from the sale of his photographs taken of birds on the Osa to Osa Birds and our conservation efforts.   To view more of Alan’s photography, or if you would like to be the proud owner of one of Alan beautiful photographs visit

Snowy Egret by Don Filipiak

Snowy Egret (Egretta thula) by Don Filipiak


Photography and herpetology have been a passion of Don’s for almost two decades. Most of his year is spent working in various disciplines of tropical biology in the rainforests of Costa Rica and Panama. With short forays back to Florida to photograph the state’s fauna, Don has become one of the highest rated guides in the Florida Everglades (  I met Don in early 2011 while climbing trees to put up artificial Scarlet Macaw nest cavities for Osa Conservation.  Well, OK Augustin Mendoza was actually doing the climbing, but Don’s appearance on the scene along with his climbing expertise was quite serendipitous.  Turns out he a man of many talents.  Not only is he an expert climber and herpetologists; his photographs are truly out of this world!
