This Kittlitz’s Murrelet was caught in Kachemak Bay, Alaska (near Homer). Note the very small bill compared to the similar Marbled Murrelet. (Photo U.S. Fish & Wildlife Service on Wikipedia)
Kittlitz’s Murrelets are an uncommon, poorly studied species. Only a few nests have been located. They indicate solitary pairs (as opposed to colonial nesters) choosing sites above the tree line on the southern slopes of rugged mountains. Often the nests are located on scree fields associated with past or present glacial activity. The pair lays just one egg. The Kittlitz’s’ diet is not well known, but as bill size and shape generally indicate feeding preferences, it might be surmised that they pursue somewhat different prey than the closely related Marbled Murrelet, which has a larger, slightly curved bill.
Although the specimen in the above photo doesn’t show it, in addition to a small bill Kittlitz’s Murrelets show golden-brown in their plumage during breeding season. Non-breeding birds tend toward mottled white and black much like their Marbled cousins, but in the Kittlitz’s the eye is surrounded by white whereas in the Marbled a black cap extends downward to cover the eye and the upper cheek. (See the photos in Marbled Murrelet – Seabird of Moss Nests and Old Growth Forests.)
This Kittlitz’s Murrelet shows a bit of golden-brown in its breeding plumage. Again, note the very small bill. Diving birds, they are known to prey on fish such as sand lances and herring as well as on crustaceans. (Photo U. S. Fish and Wildlife Services)
These are small birds, only about 9.5 inches from bill to tail. We will continue carefully checking the murrelets we encounter in Chignik Bay and Chignik Lagoon in hopes of getting a clear photograph. This is one of the rarest seabirds in North America. There aren’t many good photos of this species, and none at all that I could find of a Chignik bird. On the upside, our local coastal waters support abundant populations of both sand lances and herring which appear to be among the Kittlitz’s preferred dietary items, particularly during the nesting season. It is believed that about 14% of the Kittlitz’s population breeds on the Alaska Peninsula.
Due to this this species’ association with glaciers during breeding season, Kittlitz’s Murrelets appear to be particularly vulnerable to the impact of global warming trends.
