7 Bountiful Blue Petrel Facts

  • Blue Petrels are the only species within the genus of Halobaena.
  • Blue Petrels are one example of bird that produces a foul-smelling stomach oil that is stored in a special section of the stomach called the proventriculus. This oil is used to feed themselves while on long flights, feed their young, or it can be sprayed at predators.
  • Also like some other birds Blue Petrels have a gland that is used to secrete a saline solution in order to compensate for all the salt ingested due to their feeding in ocean waters.
  • “Petrel” refers to Saint Peter and the Biblical story of his walking on water. In order to take off Petrels require a long “runway” across the ocean’s surface. As they get up to speed they appear to run on the water.
  • Blue Petrels are pelagic (they live at sea) and only come ashore during their breeding season.
  • Blue Petrel flocks are often intermixed with other species like Thin-billed Prions, Antarctic Prions, and Salvin’s Prions.
  • Blue Petrels are mainly nocturnal during the breeding season.
