Critter News: 3 New Cassin's Auklets at the Aquarium

A first for the Seattle Aquarium — 3 Cassin’s Auklets, a new species for our collection, recently arrived from SeaWorld Orlando and are now on exhibit with the rest of our Alcid collection. These birds:

  • Have a chunky body shape with a big head and a short tail. They are grayish colored overall, darker above than below. A white spot above each eye is a distinctive field mark during breeding season. (Great eye appeal!)
  • Are fairly small with a weight range of 150-200g. Our new boys, identified as blue, yellow and purple based on their colored leg bands, weigh in the 170-190g.
  • Are one of the most wide spread Alcids and can be found from Alaska to Baja California.
  • Only birds from the Mexican colony that produce two broods in a single breeding season; they can be seen at nesting colonies every month of the year. Their Spanish name is: Alcuela norteamericana.
  • Sociable in all seasons, they are found feeding in flocks and nesting in large colonies. They feed far off shore and return to their colonies at night.
  • Cassin’s Auklets are the most abundant breeding seabirds (aside from Gulls) in Washington State where they make up 34% of all breeding seabirds, yet they breed on only six-to-eight islands: Mid-Bodelteh Island, East Bodelteh Island, Carroll Island, Jagged Island, Alexander Island (largest colony in Washington) and Dhuoyautzachtahl (all in Clallam and Jefferson Counties).
  • Like other Alcids, Cassin’s Auklets are vulnerable to disturbances from humans and introduced predators. Oil contamination is another potential threat to their feeding grounds at sea.
  • In the wild and here at the Aquarium they eat small fishes like silversides and sand eels but they absolutely LOVE krill.
