How long does a marbled murrelet live for?

LIFE CYCLE: Marbled murrelets live an average of 10 years and reach sexual maturity at two to three years of age. FEEDING: Marbled murrelets feed on a wide variety of small fish and invertebrates, including sand eels, herring, anchovy, capelin, and sardines.
How deep can a marbled murrelet dive?
This murrelet forages by pursuit diving in relatively shallow waters, usually between 20 and 80 meters in depth. We have also observed it diving in waters less than 1 meter and more than 100 meters deep. The majority of birds are found as pairs or as singles in a band about 300 to 2000 meters from shore.
What eats the marbled murrelet?
The old growth forest that’s left is often in parks where the presence of people and their food has attracted huge numbers of Jays and Ravens which eat Marbled Murrelet eggs and chicks.
Why are marbled murrelet important?
The Marbled Murrelet plays an important role in both the marine and forested ecosystems. They are important members of the marine food web, and they also fertilize trees and moss in the forest.
How many Marbled Murrelet are left in the world?
Partners in Flight estimates a global breeding population of 260,000, ranks the species a 15 out of 20 on the Continental Concern Score, and includes it on the Yellow Watch List for species in decline.

Where are Marbled Murrelet found?
The marbled murrelet is found along a north Pacific arc from Kamchatka, Russia through the Aleutian Islands to Central California. In the summer, it occurs in protected bays and coves near old-growth forests. In the winter, it is found offshore.
Why is the Marbled Murrelet endangered?
Marbled murrelets are threatened by logging and development of habitat, climate change, oil spills and entanglement. Speak up for responsible forestry practices and resource management and support conservation laws like the Endangered Species Act that protect imperiled species.
Is a Marbled Murrelet a duck?
The marbled murrelet (Brachyramphus marmoratus) is a small seabird from the North Pacific. It is a member of the auk family. It nests in old-growth forests or on the ground at higher latitudes where trees cannot grow.
How big is a marbled murrelet?
What is being done to protect the marbled murrelet?
In August 2016 the Fish and Wildlife Service finalized protections on nearly 3.7 million acres of critical habitat in Washington, Oregon and California for the marbled murrelet, firmly barring the timber industry from attempts to open up more federal lands within this area for logging.
Are Marbled Murrelet endangered?

Where do marbled murrelets nest?
growth coniferous forest
Marbled Murrelets make tree nests on large, moss- and lichen-covered branches high (usually over 40 feet) above the ground in mature and old-growth coniferous forest, normally in the largest tree in the area.
What is a marbled murrelet?
The marbled murrelet ( Brachyramphus marmoratus) is a small unique bird that gets its name from its changing feather patterns. In the winter, they turn a stark white and black color, and during their summer breeding season, they become light brown and white, taking on a marbled effect.
The Marbled Murrelet’s nesting habits remained a mystery until the late 20th century. The first nests in North America were found in the 1970s, with the surprising discovery that these murrelets nest high in old-growth trees of the Pacific Coast.
What has been spent on marbled murrelet conservation in Redwood National Parks?
Over a million dollars have been spent on marbled murrelet conservation in Redwood National and State Parks in the last 15 years. An adaptive management process was adopted to deal with an initial dearth of information.
What is the habitat of a murrelet?
Lo and behold, the nesting habitat of marbled murrelets was finally discovered––coastal old growth coniferous forests of the Pacific Northwest. With the discovery of a murrelet nest in a tree, a major evolutionary leap in seabird biology was revealed. Most animals stick to a life style similar to other closely related species.
