Common Murre

• reproducciónIt lays a single, markedly conical egg on narrow rock ledges, a shape that makes it less likely to roll off the edge.
• It builds no nest: it lays a single egg directly on the bare rock of a ledge. The egg is strongly conical, so that when it rolls it describes a circle instead of falling over the edge.
• The chick jumps from the cliff before it can fly, when it is barely a third of adult size: it hurls itself into the sea from tens of metres up and finishes growing out at sea, accompanied by its father for weeks.
