The Seagull

When circling between sea and sky, or skimming lightly over the crests¹ of the waves, the Seagull is a picture of beauty and grace. But all the while he has a keen eye to business; and a sudden dive, a splash, and the gleam of silvery scales tell us that another little fish will swim no more in the deep blue sea. Like Jack² Tar³, the Seagull gets his living on the ocean; but when fish are scarce, or the weather at sea is more than usually cold, he makes his way inland, and is content with worms and slugs and almost anything else that is eatable.
