These birds nest on the off-shore islands of The Sea of Cortez as well as South and Central America. In Baja Sur we occasionally see Boobies flying or resting on floating debris or buoys when we’re boating out-to-sea. We took these photos on The Galapagos Islands off the coast of Ecuador.
Often, especially when times are lean, if a Booby lays two eggs the stronger(usually the first hatched) will rule the nest, shoving it’s sibling aside. The mother will quit feeding the weakling and it dies. This may seem sad but it is necessary to keep the balance between these birds and food supplies.
