The Nazca Booby (Sula granti) is the largest booby in the Galapagos and is often confused with the Masked Booby (Sula dactylatra). The latter has a more yellow bill (not orange) and lesser sexual dimorphism.

Much like blue-footed boobies, Nazca boobies can look clumsy on land but once airborne, the story changes. In the air they are elegant and controlled, swift and without a doubt among the best divers in the world.

Nazca boobies practice obligate siblicide – a rare but brutal display of behaviour in which the first born chick kills its younger sibling by aggressively ousting it from the nest and, in turn, into the mouths of predators.

 

Where to see them

One of the best places to see Nazca boobies on our Land-Based Safaris is on Daphne Island – a small uninhabited islet which can be viewed from a small boat. We often incorporate a snorkeling trip at the foot of this islet as part of our Local Fishing Experience.

Another islet which is often covered with Nazca boobies is Roca Union, just off Isabela. Again this can be viewed from a small boat on our snorkeling trip to Los Tuneles (See our Isabela Safari Extension)
