Although rarely present in great numbers, Marbled and Kittzlet’s Murrelets can often be observed in the estuarial waters of Chignik Lagoon and along the rocky coast of Chignik Bay. (Chignik Bay, July 28, 2020)
Before I began this project, it never occurred to me that forest habitat might be critical to a seabird. Yet such is the case with the Marbled Murrelet. Although Russian explorers first identified this species in 1789, it’s nesting habits remained a mystery until 1974. Hoyt Foster, a tree-trimmer working high up on a Douglas Fir in California’s Big Basin Redwoods State Park noticed a ball of fluffy down in a mossy tree branch. He carefully wrapped the bird and took it to a biologist who identified it as a Marbled Murrelet chick.* Thus, a great mystery in avian biology was solved, and yet another very good reason was added to the growing list of reasons to preserve the remaining remnants of the West Coast’s old growth forests. Of particular importance to murrelets are those coastal forests growing within about 45 miles of rocky coastlines from northern California through southeastern Alaska.
Marbled Murrelet, Kenai Fjords, Alaska. The light-colored bill makes me think this is a recently-fledged specimen. Fully grown, this species measures just under 10 inches on average – small as seabirds go. (July 22, 2012)
In addition to moss covered tree branches, a smaller number of Marbled Murrelets lay their solitary egg amidst rocks on talus slopes and among boulders. Either way, the nests are unadorned and inconspicuous. Both parents feed the chick, generally returning in twilight or darkness to avoid leading predators to the nest. Like other diving seabirds, their diet consists of fish and other small animals they might catch in nearshore ocean waters.

When you think of nesting Marbled Murrelets, think of ancient trees, early morning fog sifting through fir and redwood limbs covered in thick moss and a small, vulnerable seabird nestled into that moss, her body warming one tiny, downy being

It is fascinating how often birds you’d not think would nest in trees, actually might. Such as the odd gulls I found on summer on the tiny lake in North Kenai. Bonaparte Gulls that were nesting in trees around it. They’ve not been there in years, but for two they did and it was so much fun to watch the adults! Mom called them zoomers because they flew so fast over the water.
Hi Kris, It is fascinating. What I find myself wondering is how it is that, unlike other gulls, Bonaparte’s evolved a tree-nesting strategy… And how is it that Marbled Murrelets flew inland and found mossy tree branches to their liking. The more one learns, the more there is to know, which is part of what makes birds so interesting.
Another beautiful story bird story. Love your posts.
