Two non-breeding Laysan albatrosses perform an intricate courtship dance with Midway Atoll‘s turquoise lagoon serving as backdrop. The earsplitting whistles, braying, rooster-like crows and bill clacking you will hear are all part of Laysan albatrosses‘ wonderful dance. The birds’ courting episodes can last for hours, even being performed through the night.

The Albatrosses of Kauai Return
Just in time for the first eggs to begin hatching, our Kauai Laysan Albatross cam returns. This year, we’ve upgraded the cam to include infrared illumination for nighttime viewing, and two albatross nests will be visible from the camera!
Last year’s pair, Kaluakane and Kaluahine, continue to nest onsite, but are far from the area that the camera can access. This year you’ll get to know two new albatross families on screen. The parents of the nest in front of the cam under the palm tree are mom Malumalu (band number K312) and dad Ko’olau (KP975); they are the parents of Mango, the young albatross who shared the limelight with Kaloakulua on last year’s Albatross Cam. The parents of the distant nest under the banana tree are dad Akamai (K039) and mom Ala (A379). As with last year, each of the adults has been given a name by a native Hawaiian kumu, or teacher (learn more about their names).
