    • Marbled Murrelets are unusual among the alcids in that they molt to cryptic-brown plumage during the breeding season.
    • Cassin's Auklet is one of the most widespread alcids in the northern Pacific.
    • This generality is especially true of muscles composed mostly of a single fiber type, as are the pectoral muscles of fast-flapping aerial fliers like ducks and alcids.
    • Usually you can expect to see great numbers of pelagic birds - gannets, shearwaters, jaegers, storm-petrels, alcids - that live mainly at sea.
    • The alcids (family Alcidae) have a high rate of energy expenditure during flight due to their flapping, nongliding technique.
    • Closely related to the Tufted Puffin, the Rhinoceros Auklet is a large alcid with a wedge-shaped head.
    • They are probably the most pelagic of the alcids during their non-breeding season, with many birds wintering 60-120 miles offshore.

    • The Ancient Murrelet is more agile in flight than most alcids and will often plunge directly from the air into the water to forage.
