Deepest underwater dive by a flying bird: Thick-billed murre
We usually think of birds as being great at flying, but what about at diving into water? Isn't that left entirely to penguins? Turns out, no. A good number of seabird species are skilled at diving to catch fish, but there is one species that sets the record for the deepest dive: the thick-billed murre, also called the Brünnich’s guillemot. One bird was recorded making a dive of 690 feet, descending at a maximum speed of about 6.5 feet per second! Thick-billed murres can make as many as 20 consecutive dives, taking less than a minute to rest at the surface.
