This adorable, goofy seabird is listed as Least Concern on the IUCN and can be found in the Galapagos. While the name comes from the Spanish word “bobo” (fool), these birds can be quite graceful in the air. They plunge-dive into the water to catch their prey, often in groups of 200 other birds. The species is sexually dimorphic with females being slightly larger than males with shorter tails and darker irises. Females also make a more gruff sounding “ark” call in comparison to the male’s whistle.

Boobies usually mate for life. They can be seen performing a courtship dance with their heads pointed high while they display the coloration of their feet and whistle. This breed differs from some other boobies in that they do not practice obligate brood reduction. Obligate brood reduction always results in the loss of at least one chick. However, if resources are low, the eldest chick may become stingy with food and exclude the younger chicks.

While listed as LC, threats to this species may include:

  • introduced predators
  • increasing tourism and urbanisation
  • unsustainable fishing
  • pollution
  • habitat degradation
