Razorbill

The Razorbill is a large coastal bird which congregates in groups of several thousand on rocky sea-cliffs or inside seaward-facing caves. Razorbills are voracious hunters when in a pack and will attack and eat creatures as large as a horse. Their main diet, however, is fish. Colonies are easily recognised by the stench of carrion, fish, and guano that saturates the air, and creatures venturing within 100 yards of the colony will always be set upon by four to twenty-four birds. Razorbills attack with one bite per attack. Coastal vessels, fishermen, and other seaborne targets trespassing on the colony's fishing grounds (within a mile of the colony) will be attacked by four to eighty birds. It is possible to be attacked by lone birds in any coastal region, but this is rarer.

The Razorbill resembles a large, huge-billed puffin, varying between 2 and 3 feet in length and with a minimum wingspan of 8-10 feet.
