This is bird note.

The razor bill is a black sea bird with white underparts and black head.

It's dark bill, crisply marked in white. Black Sea Bird with white underparts and black head.

Its dark bill, crisply marked in white, as a blunt rounded tip.

It stands a head taller than its cousin, the Atlantic puffin. Razorbill's nest in colonies, principally on the coast of Iceland,

in crevices among boulders.

To feed, they make wing-propelled dives to hunt small fish, sometimes reaching depths below 300 feet.

Pairs usually made for life, but perhaps the most remarkable thing about razor bills is

their synchronized swimming.

Before they lay eggs in summer, they take part in two different group social behaviors.

In one, the razorbill swim round and round at a tight mess,

then dive as one.

Next, they all surface together,

with heads aligned and stretched upward,

with their bills held open.

In a second group behavior, dozens of birds swim in a line, then zigzag together in a

synchronized pattern across the ocean surface.

For razorbills, which breed and hunt for food in groups,

these carefully coordinated movements

are how they get in sync.
