Double-crested Cormorant — Water Connection, page 2

• Cormorants’ powerful webbed feet propel them as they dive and pursue fish underwater. They capture fish by grabbing them with their bill, then swallow their prey once back on the surface.

• Cormorants have been known to dive 35 feet or more, though usually they forage at depths of less than 20 feet. They usually remain submerged for 20-25 seconds, but can stay underwater for up to 45 seconds.

• When alighting on the water, Cormorants use their tails as brakes, dragging them along the surface to slow their speed.     next page >>
