many of them were repairing and augmenting nests that had remained
through the winter, while others were employed in constructing new ones,
and some were already sitting on their eggs. In a great many instances, the
repaired nests formed masses nearly two feet in height, and yet all of them
had only a slight hollow for the eggs, broken shells of which were found
among the entire ones, as if they had been purposely placed there. The
birds did not discontinue their labours, although there were nine or ten of us
walking among the bushes, and when we had gone a few yards into the
thicket, thousands of them flew quite low over us, some at times coming so
close as to enable us to catch a few of them with the hand. On one side
might be seen a Noddy carrying a stick in its bill, or a bird picking up
something from the ground to add to its nest; on the other several were
seen sitting on their eggs unconscious of danger, while their mates brought
them food. The greater part rose on wing as we advanced, but re-alighted
as soon as we had passed. The bushes were rarely taller than ourselves, so
that we could easily see the eggs in the nests. This was quite a new sight
to me, and not less pleasing than unexpected.
The Noddy, like most other species of Terns, lays three eggs, which average two inches in length, by an inch and three-eighths in breadth, and are of a reddish-yellow colour, spotted and patched with dull red and faint purple. They afford excellent eating, and our sailors seldom failed to collect bucketsful of them daily during our stay at the Tortugas. The wreckers, assured me that the young birds remain along with the old through the winter, in which respect the Noddy, if this account be correct, differs from other species, the young of which keep by themselves until spring. At the approach of a boat, the Noddies never flew off their island, in the manner of the Sooty Terns. They appeared to go farther out to sea than those birds, in search of their food, which consists of fishes mostly caught amid the floating sea-weeds, these Terns seizing them, not by plunging perpendicularly downwards, as other species do, but by skimming close over the surface in the manner of Gulls, and also by alighting and swimming round the edges of the weeds. This I had abundant opportunities of seeing while on the Gulf of Mexico.
The flight of this bird greatly resembles that of the Night Hawk when passing over meadows or rivers. When about to alight on the water, the Noddy keeps its wings extended upwards, and touches it first with its feet. It swims with considerable buoyancy and grace, and at times immerses its head to seize on a fish. It does not see well by night, and it is perhaps for this reason that it frequently alights on the spars of vessels, where it sleeps so sound that the seamen often catch them. When seized in the hand, it utters a rough cry, not unlike that of a young American Crow taken from
