MANX SHEARWATER (Puffinus puffinus). Length : 1 foot. Range: European 
North Atlantic. 
Shearwaters choose a spot high up on a cliff in which to make their bur¬ 
rows. Sometimes one entrance leads to several nests. Skimming the surface of 
the sea, these birds seem really to be “shearing” the wave tops.
