The marbled murrelet is a small seabird found along the Pacific coast of North America. It is known for its distinctive plumage, which features a mix of dark brown and white colors, resembling a marbled pattern. This bird typically measures about 25 to 30 centimeters in length and has a wingspan of around 60 centimeters. Marbled murrelets are unique among seabirds because they nest in old-growth forests, laying their eggs on mossy branches rather than on the ground or cliffs. Their primary diet consists of small fish and invertebrates, which they catch while diving underwater. Conservation efforts are ongoing to protect their habitat, as they are considered a threatened species due to habitat loss and environmental changes.
