Birds and Nature, Vol. 12 No. 3 [August 1902]

“The ends of the upper wings terminate in a fine point, just as the leaves of many tropical shrubs and trees are pointed, while the lower wings are somewhat more obtuse, and are lengthened out into a short thick tail. Between these two points there runs a dark curved line, exactly representing the midrib of a leaf, and from this radiate on each side a few oblique marks, which well imitate the lateral veins. These marks are more clearly seen on the outer portion of the base of the wings and on the inner side toward the middle and apex, and they are produced by striae and markings which are very common in allied species, but which are here modified and strengthened so as to imitate more exactly the venation of a leaf.

“The habit of the species is always to rest on a dead twig and among dead or dried leaves, and in this position, with the wings closely pressed together, their outline is exactly that of a moderately sized leaf, slightly curved or shrivelled. The tail of the hind wing forms a perfect stalk, and touches the stick while the insect is supported by the middle pair of legs, which are not noticed among the twigs and fibers that surround it. The head and antennae are drawn back between the wings, so as to be quite concealed, and there is a little notch hollowed out at the very base of the wings, which allows the head to be retracted sufficiently. All these varied details combine to produce a disguise that is so complete and marvellous as to astonish everyone who observes it; and the habits of the insects are such as to utilize all these peculiarities, and render them available in such a manner as to remove all doubt of the purpose of this singular case of mimicry, which is undoubtedly a protection to the insect. Its strong, swift flight is sufficient to save it from its enemies when on the wing, but if it were equally conspicuous when at rest, it could not long escape extinction owing to the attacks of the insectivorous birds and reptiles that abound in tropical forests.”

IN AUTUMN

The waves come galloping up the shore,The trees are flinging their arms about.All night I have heard the wind’s loud roar,And the surf call back with angry shout.And after the wind a grieving rainComes sighing and sobbing past my door,“The summer flowers I seek in vain,Is my work of love forever o’er?”One day ago and a soft sun shone,Butterflies flitted through quiet air,But now both they and the birds are goneAnd soon will the trees be stripped and bare.Though winds blow cold and the skies are gray,The sun of summer still shines for me,For naught can drive from my heart away,The memory of bird and flower and tree.Grace Wickham Curran.

BEAUTIFUL VINES TO BE FOUND IN OUR WILD WOODS

As the summer closes and the trees, flowers and vines have all reached their greatest perfection, have fulfilled their mission in life, and in addition have beautified all the spring and summer our lawns and verandas, and have been admired as wonderful children of the florists’ skill, how many of us know that many of them and especially most of these beautiful vines, could be found in our wild woods just for the looking? That we could with our own hands transplant them to our homes and have just as beautiful vines on our little porches and verandas as any millionaire on our boulevards?

One vine that we see covering our stateliest mansions and growing over our most humble little cottage, is common in all the woods of the United States from Maine to Florida, from New York to California, is the Ampelopsis quinquefolia – or Virginia creeper – American ivy or woodbine – its name changing with the portion of the country you happen to be when you find it, for we see it frequently under its various names in cultivation, and it certainly grows in great abundance and in the most graceful ways in our woods, over trees and shrubs and old rock fences, clinging in the most loving way to any surface with which it comes in contact. It belongs to the order Vitaceæ or Vine family, which is a family of climbing shrubs, and to which all of our wild grapes belong.

Its name Ampelopsis is from two Greek words, meaning vine and appearance; quinquefolia, five leaved or fingered; its leaves being alternate and compound, with five leaflets, long and pointed, radiating from the center. It may be that it was meant to signify that our five fingers may handle it recklessly and not run any risk of poisoning, as so many people are fearful of being – they being unable to distinguish it from the Rhus radicans or poison ivy – which belongs with the sumachs, and has only three leaflets or divisions in its leaves. This poison ivy could be so easily exterminated if every one who finds a plant of it would dig it up and burn it. It surely is as much one’s duty to help exterminate a poisonous plant as it is to cultivate and nourish an ornamental, beautiful, harmless one. Yet there is hardly a park in our larger cities where you will not find the Rhus radicans or poison ivy growing.

In the Virginia creeper we will find tendrils growing from the base of its leaves, that swell at their tips into sucker like disks, by means of which the plant clings firmly to walls and trees in its extensive climbing. The flowers of this beautiful vine are small, inconspicuous and greenish in color, with five concave thick spreading petals, with a calyx slightly five toothed, a two celled ovary or seed vessel, each cell containing two seeds. It blooms early in June and in the early autumn, when its leaves are turning the most exquisite shades of scarlet and crimson, these little flowers develop into clusters of deep blue or purple berries about the size of peas.

The whole vine is really more beautiful in the autumn than it is in the spring, and it surely does more than its part in making our American woodlands such great expanses of gorgeous coloring in the fall as to attract the attention and remarks of all visiting foreigners.

SOME SNAILS OF THE OCEAN

The Marine snails outnumber all of the other mollusks and their shells are far more beautiful, those in the tropics having the most gaudy colors imaginable. The animals are all formed on the same plan although each family has some peculiarity not shared by its relatives. They are found in all parts of the world, and in all climates. While the majority of species live either between tides on near low water, there are not a few which live in the abysses of the ocean and have been dredged at a depth of three thousand fathoms, a distance of over three miles. The average depth at which mollusks are found in any number is about one thousand fathoms. The variability of marine snails is so great that only a few typical forms can be mentioned.

The Limpet or Patella is a familiar mollusk to many visitors at the sea shore. This shell is a depressed, conical, oval disk, looking not unlike a miniature shield. They live on rocks, to which they tenaciously cling. Some experiments which were made on the English limpet several years ago showed that they could sustain a weight of thirty pounds attached to their shell without being pulled from the rock. The animal seems to have a pretty clear idea of local geography, for it invariably returns to the same place after its excursions for food and the rock in some localities has been hollowed out to a considerable depth by the continuous dwelling thereon of the limpet. If the surface of the rock is uneven the shell grows in such a manner as to fit these inequalities. While grazing along the sides of a rock covered with fine sea weed it will leave a track like a worm and will clear off quite an area in a very short space of time. This track is made by the radula, which is very long and is thrust out and loaded with food which it carries to the mouth. When at rest the radula is coiled like a watch spring. On the British coast the limpet is used as an article of food and primitive man not only ate the mollusks but made a necklace by stringing the shells together. There are several hundred species of limpet-like shells and they are found in all parts of the world, especially on rocky shores.

A family of shells closely related to the limpets is the Fissurellidæ, or keyhole limpet, distinguished from the last family by having a slit or foramen in the apex of the shell, through which the waste products of digestion are discharged. This slit resembles a key-hole and for this reason they are called key-hole limpets. The shells of Fissurella are generally rougher than those of Patella and they live, as a rule, in warmer seas. In habits the key-hole limpet resembles the limpet, living in one rocky place and making excursions for food. In the young shell the spire is without a perforation, this appearing as the shell increases in age. There are over one hundred species of key-hole limpets, several handsome species of which inhabit Florida and the West Indies.

The Haliotis or abalone shells abound in many parts of the world and are widely known for their beauty. The largest and finest shells live on the coast of California where they attain a length of ten inches. The shells are flat, though made in the form of a spiral and are perforated near the edge of the last whorl, which is many times the size of all the rest combined, and through this perforation the water from the gills, together with the waste products of the animal, are poured out. As the shell increases in size the old holes are filled up and new ones are formed. The inside of the shell is resplendent with iridescent colors, particularly about the region of the huge muscle scar, and when the outside is polished they become objects fit for the palace of a king. A large part of the mother-of-pearl is furnished by these shells and a vast number are annually exported for the purpose of making pearl buttons. In England they are called “Ormers” but the correct name, if we translate the generic title, is “Sea-ear” or ear-shells. To the Chinese the abalone is an object of great economic importance and they gather them in large quantities, dry the animals and use them as food, principally in the form of soup, which is said to be very delicious. The abalone clings to the rocks with terrible power and many a lonely fisherman has been drowned while gathering this mollusk, by getting his fingers caught between the shell and the rock.

There are three families of shells which are much sought after by conchologists, these are the top shells (Trochidæ), the turban shells (Turbinidæ) and the pheasant shells (Phasionellidæ). Altogether they embrace nearly five hundred species which live from the shore between tides to the lowest depths of the ocean. The shells of the top shells vary to a wonderful degree; some are large, others small; some are perfectly plain and smooth while others are ornamented by impressed lines, ribs and granules, some are very thin and delicate while others are large and massive. Many of the species are richly colored with brown, purple, black, green and yellowish, and all are more or less pearly. They are all vegetable eaters.

One of the best known is Trochus niloticus, a large, massive shell striped with brown, which is seen on the mantle of many households. One of the prettiest top shells is the ringed top shell (Calliostoma annulatum) found abundantly in some parts of California. The surface is marked by several rows of delicate points and the suture is bordered by a rich line of purple. It lives in the seaweed off shore and may be seen in pleasant weather crawling about among the weeds. During storms or rough weather this frail mollusk sinks to the bottom of the sea. The top shells inhabit many parts of the world, the coasts of Florida and California producing several very handsome and interesting species.

The Turban shells include many fine and large shells, a notable species being Turbo marmoratus, the “green turban” of the dealers. This shell is about seven inches in diameter, rich green outside and pearly inside. It is largely used for mother-of-pearl work and for making pearl buttons. It is said that the early Scandinavian monarchs used this shell as a drinking cup. At the present time it is used for ornamental purposes, richly mounted. In Japan the animal is used for making chop suey, being cut in little dice-like pieces.

The Pheasant shells are beautifully variegated with red, black, white and brown and are very interesting animals to study alive. When crawling, the left side of the foot moves forward while the right remains stationary, and when the right side moves the left remains stationary. This curious mode of progression has been likened to the canter of a horse. The larger species, with beautifully variegated shells, inhabit Australia, while the smaller species live in the Mediterranean Sea, South Africa, the West Indies and California.

The Neritas are very abundant in tropical and semi-tropical countries where they live on rocks and stones near low water mark. They are said to be nocturnal and spend the night feeding on seaweed. The shell of the Nerita is solid and heavy and variously ornamented with ribs, pustules and color patterns. The “bleeding tooth shell” (Nerita peloronta), so named from the presence of a red spot near one of the columella teeth, is a typical member of this genus. A species living in the Philippine Islands is said to climb trees to a considerable height.

The family Cerithiidae comprises some very handsome shells which inhabit salt, brackish and fresh water. They are found throughout the world but the finest species live in the tropics. The spire is very long and is composed of many whorls. Some shells are smooth and polished, while others are marked by frills, knobs, spines and ribs. The name Cerithium is from the Greek word ceration, meaning a small horn, and is used because of the horn-like shape of the shell. This family has its giants and also its pygmies, the latter being pretty, reticulated shells from one fourth to three fourths of an inch in length, living among the eel grass and other vegetation along the shore. There are over a hundred species of these small shells, and some when handled discharge a bright green fluid.

Whoever visits the seashore is bound to become intimately acquainted with the Littorinas, or periwinkles, for they cover the rocky shores everywhere, millions of their rounded shells clinging to the rocks when the tide goes out. They feed on the algae which grows on the shore. They are found in both brackish and fresh water. The common periwinkle (Littorina littorea) is extremely abundant on the shores of southern Europe and the northern part of the United States. In England it is used as an article of food and it is said that nearly two thousand tons are gathered annually and that a thousand persons are employed in capturing it. In London and other large cities they are sold on the street, the animal being picked out with a pin. It is used for bait in some of the fisheries and the oystermen plant many bushels on their oyster beds yearly to keep the seaweeds from accumulating. From these facts it will appear that this periwinkle is of considerable economic importance. All of the species are amphibious, living for a long time out of the water.

Of all the gastropods none excel the curious Xenophora in point of oddity. The shell is in general form like that of the top shell, but as it grows it attaches to itself small stones and pieces of shell, so that when the animal is fully grown it looks like a heap of dead shells and pebbles. This habit is in all probability to conceal the animal from its enemies. They are called “carriers” and the individuals with shells attached to their house are called Conchologists, while those with stones attached are called Mineralogists. The fragments of shells are attached with concave sides upward so as not to impede the animal during locomotion. The carriers are not able to glide like other mollusks, their feet being very small. They progress by lifting the front part of the foot to an object and then drawing the hind part toward it. In this way they jump or scramble along in a ludicrous manner.

Related to the “carriers” are the slipper-shells (Crepidula), the horse-hoof shell (Hipponyx) and the bonnet-limpet (Capulus). The slipper shells are found in many parts of the world and are particularly abundant on the Atlantic and Pacific shores of the United States. The shell is flat and somewhat limpet-like, and across one end, near the apex, is a little shelf which gives it the appearance of a Chinese slipper. They adhere to stones, shells, crabs and any submerged object, and modify the form of their shell to fit the inequalities of their resting place. Thus a Crepidula on a Pecten shell will be ribbed while the same species on a stone will be perfectly smooth. Frequently they may be seen piled one upon another in tiers of six or more. The animal generally feeds on seaweed but has been known to eat other mollusks. The bonnet limpets also belong to this family, as do the cup-and-saucer limpets (Calyptraea).

The family Strombidae contains many large and interesting shells. The animal is very powerful and is able to leap a considerable distance. Mr. Arthur Adams, a celebrated conchologist, thus describes its method of leaping: “Planting firmly its powerful, narrow operculum against any resisting surface, it insinuates it under the edge of its shell and by a vigorous effort, throwing itself forwards, carrying its great heavy shell with it, the animal rolls along in a series of jumps in a most singular and grotesque manner.” The eyes of the animal are greatly developed. The shells of Strombus vary greatly in form and color. In some the outer lip is simply turned over while in others it is modified by little spines or projections. The aperture is frequently colored pink, purple or yellowish. The large Strombus gigas is used in carving cameos, its shell being made up of several layers of different colors. It is also ground to powder for the manufacture of porcelain and in the West Indies the animal is used as an article of food.

The Auger or steeple shells, belonging to the family Terebridae, have long been objects of interest not only to the naturalist but to the layman who places them in his house as ornaments. There are about two hundred species which are found in many parts of the world, although chiefly confined to tropical seas. The shells are very long and are composed of many tightly wound whorls, which are smooth in some species and longitudinally ribbed in others. They vary also in color, being yellowish, grayish or brownish, and many species are spotted with red or white.

A group of handsome mollusks live in the tropics whose shells have been named Mitra by the naturalist Lamarck from their fancied resemblance to the Pope’s miter. The shells are fusiform, very thick and heavy and beautifully ornamented with various colors. The surface of the shells of some species is smooth, others granulose and not a few spirally lined and longitudinally ribbed, while the columella is marked by several heavy plaits or folds. There are about two hundred species of this genus, living in all parts of the world but being more numerous in tropical regions. The Philippine Islands seem to be the metropolis of this mollusk, as of others, and their shores fairly teem with the graceful creatures. Some of them live among the coral reefs, concealing themselves in holes or among the sea weeds or under stones. Others live on the sandy or muddy beaches in which they bury themselves when the tide recedes.

The earlier naturalists were fond of applying significant names to the shells which they described and the Mitras have received their share. Thus we have the episcopal miter, having a white shell with brilliant red spots and flame; the papal miter, with a brown-spotted white shell; the pontifical miter, with a red-spotted shell and a coronated spire, and lastly the cardinal’s miter. These four species might be called the ecclesiastical quartette.

The Harp shells, although few in species, are among the most showy of the marine snails. The shells are large and marked by many elevated ribs extending longitudinally, giving the effect of the strings on a harp, hence the name of the genus. The colors are different shades of brown which form neat festoons of dark brown lines between the ribs. The inner lip of the shell is marked by a dark brown spot and another spot is frequently developed near the upper part of the whorl. In one species (Harpa rosea) the shell is marked by several rosy spots and tints, and is very beautiful. The animal of this genus is no less interesting than the shell, being variegated with many beautiful colors. The foot is long, crescent shaped in front and becomes narrowed to a point behind. The animal is said to voluntarily break off a piece of its shell when irritated, as it is not able to retreat within the shell, being destitute of an operculum. It is very active and crawls about with an easy, graceful motion. Harpa lives only in the tropics and is found in the Indian and Pacific Oceans and on the west coast of America.

The Bubble shells include within their number many curious and interesting animals. The typical genus, Bulla, numbers some fifty species of smooth, globular shells, frequently mottled like a bird’s egg. The aperture is as long as the shell and the outer lip is thin and sharp. The animal is large and fleshy and partly envelops the shell. The bubble shells love sandy mud flats in which they bury themselves or find concealment under masses of sea weed. Like many land shells they exude vast quantities of mucus to moisten their skin when the tide is out. These animals are carnivorous, living on bivalves and snails, which are swallowed whole and reduced to fragments by the huge, calcareous gizzard. Not all the mollusks of this order have true shells. The so-called sea hares, have large, flabby bodies in which is lodged a small, oblong, transparent shell. This animal lives among the sea weed, feeding upon the weed as well as upon mollusks and other animals. It discharges a violet liquid when handled which caused the ancients to believe that it was poisonous. The old Greek philosophers wrote a great deal on this subject, believing that to even touch the animal with a stick would cause death. Though repulsive looking creatures they are perfectly harmless and are even eaten raw by the natives of the Friendly and the Society Islands.

JOIN A SUNRISE CLUB

Join a sunrise club? as is proposed in Birds and Nature for January. Of course I will. I have for years belonged to one of two members – my daughter and myself. Now we will transfer our membership to the new club that is to have members all over the country.

Some of our winter sunsets here in Nebraska are glorious. I am especially fond of looking at them through the thousand interlaced branches of the leafless trees. One can study tree forms and sunsets in the same picture. I wonder that every person is not a sunset observer. But some people are sunset blind, and some rarely ever look at the heavens on starry nights. I sometimes meet people who lament the fact that they cannot go to Colorado and see the mountains, of which they hear such glowing accounts. I tell them that I do not pity them at all so long as they do not care to gaze upon the most glorious sight which mortal man is permitted to see – the starry heavens. They who do not appreciate the stars and the sunsets would soon tire of the mountains.

Our summer sunsets are also glorious, but I miss some of them on account of the trees around my house. I sometimes get on my wheel and go out of town simply to see the sunset. Trees are nice, but they often hide from us something nicer. When the towns of Colorado were new, twenty-five years ago, we could see the mountains from all our west doors and windows. Now in those same towns the people must go out into the street, or even out of town, if they would see the mountains in summer.

But, say, let us have another club – a Sunrise Club. It may be asking too much to make it operative for the whole year, so we will call it a sunrise club for May and June. Those are the bird months of the year, the months when some of us are out before sunrise morning after morning, to watch the birds and to hear their wonderful concerts. Some of the pleasantest memories of my life are of early morning trips on my wheel to a certain grove in the edge of town. On those trips I have seen many a new bird – new to me – and many a glorious sunrise.

Somehow birds and the rising of the sun fit into each other beautifully.

There is something inspiring and exhilarating about sunrise that is not found in sunsets. The air is more free from dust; one’s body and mind, yes, and soul, too, are in better mood to enjoy the sight; one is more pleased to welcome the sun than to bid him good night; the birds seem to think so and they give joyous welcome to the orb of day; all nature is awakening; a great thing is happening; a new day, fresh from the hands of its Maker, is being born. All hail, thou new creation! Welcome, thou glorious orb of day! Let me join with the birds in singing thy praise. Thou dost flood my soul with joy even as thou dost flood the earth with light. Yes, let us have a sunrise club for May and June, except perhaps the cloudy and stormy mornings when even the birds seem to lie abed. Who will join?
