DEGANGE, A .R Status and distribution of the Kittlitz’s Murrelet Brachyramphus brevirostris along Alaska Peninsula Kodiak Aleutian islands, Marine Ornithology 39: 111–122 The is adapted for life in glacial-marine ecosystems, being concentrated belt glaciated fjords northern Gulf from Glacier Bay to Cook Inlet Most remaining birds are scattered coasts Islands, where they reside protected bays inlets, often proximity remnant glaciers or recently deglaciated landscapes We summarize existing information on this mainly unglaciated region, extending Island east Near Islands west From recent surveys, we estimated that ~2400 Murrelets were found several large embayments Peninsula, adjacent ice fields feed silt-laden water into On Island, only remnants remain today, observations at sea uncommon species has been observed historically around entire Archipelago, however, dozens nest sites years a few islands chain, notably those with long complex shorelines, high mountains largest population (~1600 birds) outside was Unalaska which also supports greatest concentration glacial Significant populations Atka (~1100 birds), Attu (~800) Adak (~200) Smaller numbers have reported Unimak, Umnak, Amlia, Kanaga, Tanaga, Kiska Agattu located not thoroughly surveyed, significant pockets may yet be discovered Our estimate ~6000 likely conservative because survey protocols employed (i .e early seasonal timing strip transects)
