I love these birds. We rarely sail into Cornwall without one for company. There are times when you could be forgiven for thinking it was the same bird following us; but that, of course, is daft whimsy.
Sleek, graceful creatures, they swoop low over the waves, or in wide circles above, before furling their wings and plummeting straight down into the water. And occasionally, such a plunge heralds the appearance of dolphins or porpoises, no doubt drawn by the same bounty just beneath the waves.
It was an especially pretty sky over the English Channel this weekend just gone.
