As you make your way up through the Arctic Terns and out on to the top of the island you soon come across a small colony of Sandwich Terns. These are a similar size but are whiter with a black cap which can be raised when under duress into a shaggy crest. For some reason hemmed in together , hassled by gulls and photographers, they always seem to be a little stressed! They have a slim black beak with a yellow tip.
They nest crammed in together for protection and safety and will lay 1-3 eggs. Like the arctic tern as soon as the chicks hatch the parents are continually flying in with single sand eels to feed the growing chicks.
They are one of the earliest returning migrants to the UK generally starting to be spotted around March. Although their migration isn't as impressive as the Arctic tern they will still cover huge distances with many overwintering as far away as South Africa. There are thought to be around 12.000 breeding pairs in the UK.
Like all terns they are incredible fliers and pull off incredible manoeuvres sometimes with their head the wrong way round.
The final tern seen on the Farne is the Common tern which is more silver with a red beak with a black tip. They also breed in noisy colonies and are graceful fliers and slightly more obvious because of their longer tails which have got them dubbed the "sea swallow".
Although named Common the breeding numbers of these on the Farnes are much lower than the other two and most of them nest around the lighthouse at the top of the island.
There is one other tern which may be seen fishing around the Farnes but doesn't breed on the island. This is the Roseate tern of which more later.
