Behavior

The Whiskered Auklet is a highly social but elusive seabird, spending the vast majority of its life at sea within the turbulent waters of the Aleutian and Kuril Islands. Unlike many other alcids, they are often found near 'tide rips'—areas where strong currents collide—to forage on concentrated plankton. They are famous among researchers for their 'citrus-like' scent, a social odor they produce during the breeding season that may help in mate recognition or individual health signaling.

On land, these birds are primarily crepuscular or nocturnal, arriving at their nesting colonies under the cover of darkness to avoid predation by larger gulls and eagles. They are cavity nesters, squeezing their tiny bodies into deep rock crevices or volcanic talus slopes. Despite their small size, they are incredibly hardy, navigating some of the roughest maritime environments on the planet with surprising agility.

Camera Tips

Capturing the Whiskered Auklet on camera is a specialized challenge due to their remote habitat and nocturnal land habits. If you are in a coastal Aleutian region, focus your camera placement on stable talus slopes or rocky cliff faces where small crevices are visible. Because these birds arrive at nesting sites in low light or total darkness, a camera with high-quality infrared (IR) or 'no-glow' LEDs is essential to capture clear images without startling the birds or attracting predators to the site.

Set your camera at a low angle, roughly 12 to 24 inches off the ground, pointed toward the entrance of a rock cavity. Since these birds are incredibly fast and small, use the fastest trigger speed available (0.2 seconds or less) and set the camera to 'burst mode' or 'rapid-fire' to take 3-5 photos per trigger. This increases your chances of getting a clear shot of their unique facial plumes as they scurry into their burrows.

Aleutian weather is notoriously harsh, so ensure your camera housing is rated for extreme moisture and high winds. Secure the camera to a heavy rock or a weighted tripod, as the gusts in their habitat can easily tip over standard equipment. Avoid using artificial lures or food; instead, look for 'whitewash' (guano) markings on rocks, which indicate high-traffic entry points to their nesting colonies. The best time for recording is during the peak breeding months of June and July when activity is at its highest.

Frequently Asked Questions

Whiskered Auklets are primarily crepuscular and nocturnal when on land. They return to their nesting colonies under the cover of darkness, usually between late evening and the early pre-dawn hours, to avoid being spotted by predators like Glaucous-winged Gulls.

Whiskered Auklets cannot be attracted to typical backyards as they are strictly marine birds. They only come to land on remote, rocky islands in the Aleutian or Kuril chains. Supporting ocean conservation and reducing plastic pollution are the best ways to help this species from afar.

Their diet consists almost entirely of zooplankton. They are particularly fond of tiny crustaceans called copepods and krill, which they catch by 'flying' underwater using their wings as flippers.

No, they are never found in suburban areas. They have a very restricted range and are found only in the North Pacific, specifically around the Aleutian Islands and parts of Siberia.

While both have forehead crests, the Whiskered Auklet is much smaller and has three distinct pairs of long white 'whisker' plumes on its face. The Crested Auklet is larger and lacks the elaborate triple-whisker pattern.
