Nazca Booby, Galapagos Islands, EcuadorOf the three different booby species that I photographed in the Galapagos Islands, the Nazca booby was by far the most common. This guy, in fact, was the first individual bird of any species that I encountered on day one in the islands. He seemed as curious about me as I was about him. Nazca boobies practice what is called obligate siblicide. What is obligate siblicide? I’ll let Wikipedia explain — “Mothers lay two eggs, several days apart. If both eggs hatch, the elder chick pushes its sibling out of the nest area, leaving it to die of thirst or cold. The parent booby cannot intervene and the younger chick inevitably dies. Two eggs are laid so that if one gets destroyed or eaten, or the first chick dies soon after hatching, the second egg will produce an offspring.” Life clearly ain’t easy for a young booby.
