The razorbill is a native seabird to Ireland and to Scotland which is where this image is from, over on Mull just up the coast from my home county of Antrim right in the north east corner of Ireland.

Related to the puffin, the razorbill can often be seen nesting and breeding in colonies that include puffins, as well as fulmars along the Atlantic coasts of Ireland and Scotland.

Unlike the puffin, the razorbill is usually only seen as a plain black and white bird, with its distinctive line running from the bill back to its brown-iris eyes as seen in the image above.

But, when it opens its bill there is a flash of bright, almost golden yellow on the bird's palate.

This pair are engaging in mating behaviour but the bright yellow can also be useful for chicks being fed and razorbills often quarrel with each other with bills wide open in what is known as bill-gaping.

Each pair will only have one egg and both male and female feed the chick for approximately three weeks.

At around twenty days old the chicks follow the male into the ocean, leaping from the cliff and are fed by him until old enough to become self-sufficient.

Like fulmars, razorbills can live to forty years or more.
