The highest tree nest constructed by any bird is that of the marbled murrelet (Brachyramphus marmoratus), a small North Pacific member of the auk family of seabirds. Its nests have been discovered as high as 45 m (147.64 ft), usually on moss-covered branches of old conifer trees. This may explain why the first formally identified nest from this species was not recorded by science until as recently as 1961, in Asia; the first North American example was not found until 1974.
