Prions are small seabirds belonging to the genus Pachyptila that inhabit the Antarctic and sub-Antarctic regions.1
Breeding
Most prions breed in burrows located on Antarctic and sub-Antarctic islands. The broad-billed prion, specifically, has a more northerly distribution, typically breeding on islands situated between 35° and 60° S.1
Feeding
Prions feed on small marine invertebrates, including crustaceans and squid. They employ a unique feeding method known as "hydroplaning," where the bird skitters across the surface of the water with its wings extended and feet propelling it forward. While doing so, it dips its specialized, flattened bill into the water to strain food using internal structures called lamellae.1
