Pool Cleaning

Twice a year, usually one day in the spring and one day in the fall, Penguin & Puffin Coast is closed to guests for our bi-annual pool dump and puffin health checks.  This year’s first cleaning was held on Wednesday of this week. We performed routine maintenance around the exhibit (acrylic buffing, replacement of light bulbs, dusting) and drained the inside pools so keepers could scrub and power wash algae and sediment from the pool floors.

The penguins stay on land during the cleaning, but the puffins are placed in crates so that keepers can perform a health check on each bird. Puffins are much less social than penguins, so it is not as easy to do a routine health check on them as it is with the penguins. Each puffin is weighed to ensure they are maintaining a healthy weight and checked by hand for feet, beak, wing and plumage condition.

The whole process, including refilling the pool, can take about five hours. By early afternoon, it’s time for the penguins and puffins to get back in the water and swim – which they are eager to do! 

Penguin & Puffin Coast is now open. Free, timed tickets are required to enter Penguin & Puffin Coast and are available at a Welcome Desk, located at either Zoo entrance, or at any Zoo attraction ticket booth.
