High-Speed Flyers Marbled murrelets are known to cruise about 60 miles per hour between their nests and ocean feeding grounds. Murrelets are general found in near-shore waters (within 3 miles from the coast) with nesting areas nearby. The Marbled Murrelet (Brachyramphus marmoratus) occurs only in North America, from Alaska south to Santa Cruz, California (Nelson 1997), and wintering as far south as Baja California, Mexico (Erickson et al. Because of this, there are still gaps in our knowledge of habitat use by this species, especially for nesting birds in Oregon. They are difficult to detect, and tend to nest high up in the canopy.

Murrelet Predators in Fragmented Forests Burger et al. Species Common Name Marbled Murrelet Species Scientific Name Brachyramphus marmoratus; Federal Listing Status Threatened State Listing Status Threatened Ecoregions. Murrelet nestlings are not attended by adults; thus our simulated nestlings were realistic, and may provide olfactory cues similar to that of a real nestling with its odorous fecal ring. Marbled Murrelets are secretive and nest as solitary pairs at low densities, typically in old-growth forests within 30km of the sea. Murrelets hunt and fly at night to avoid leading predators to the nest. However, forest fragmentation can open the forest to new predators that are more adept at detecting murrelets and their eggs.

Marbled Murrelets depend on both marine and forest habitat. 43-46; Johnson 1993, pp. Here are a few things we know about these elusive seabirds. important to know whether edge effects and fragmentation have significant impacts on sensitive forest-nesting species such as the marbled murrelet.

Marbled murrelets’ main predators are ravens, crows, jays, owls and hawks but they are also threatened by logging in nesting habitats, oil spills, and entanglement in fishing nets. In the 1996 rule we hypothesized that populations of marbled murrelet predators such as corvids (jays, crows, and ravens) and great horned owls are increasing in the western United States, largely in response to habitat changes and food sources provided by humans (Robbins et al. Marbled murrelets’ main predators are ravens, crows, jays, owls and hawks but they are also threatened by logging in nesting habitats, oil spills, and entanglement in fishing nets. ... risk of being spotted by predators. 1995).

Oregon’s Coast Range, known for its dramatic scenery, is extremely diverse, with habitats ranging from open sandy dunes to lush forests and from tidepools to headwater streams.
