NOTES BY THE WAY

A NEW NOTE IN THE WOODS

THERE is always a new page to be turned in natural history, if one is sufficiently on the alert. I did not know that the eagle celebrated his nuptials in the air till one early spring day I saw a pair of them fall from the sky with talons hooked together. They dropped a hundred feet or more, in a wild embrace, their great wings fanning the air, then separated and mounted aloft, tracing their great circles against the clouds. "Watch and wait" is the naturalist's sign. For years I have been trying to ascertain for a certainty the author of that fine plaintive piping to be heard more or less frequently, according to the weather, in our summer and autumn woods. It is a note that much resembles that of our small marsh frog in spring,--the hyla; it is not quite so clear and a.s.sured, but otherwise much the same. Of a very warm October day I have heard the wood vocal with it; it seemed to proceed from every stump and tree about one. Ordinarily it is heard only at intervals throughout the woods. Approach never so cautiously the spot from which the sound proceeds, and it instantly ceases, and you may watch for an hour without again hearing it. Is it a frog, I said, the small tree-frog, the piper of the marshes, repeating his spring note, but little changed, amid the trees? Doubtless it is, yet I must see him in the very act. So I watched and waited, but to no purpose, till one day, while bee-hunting in the woods, I heard the sound proceed from beneath the leaves at my feet.

Keeping entirely quiet, the little musician presently emerged, and, lifting himself up on a small stick, his throat palpitated and the plaintive note again came forth. "The queerest frog ever I saw," said a youth who accompanied me, and whom I had enlisted to help solve the mystery. No; it was no frog or toad at all, but the small red salamander, commonly called lizard. The color is not strictly red, but a dull orange, variegated with minute specks or spots. This was the mysterious piper, then, heard from May till November through all our woods, sometimes on trees, but usually on or near the ground. It makes more music in the woods in autumn than any bird. It is a pretty, inoffensive creature, walks as awkwardly as a baby, and may often be found beneath stones and old logs in the woods, where, buried in the mould, it pa.s.ses the winter. (I suspect there is a species of little frog--Pickering's hyla [footnote: A frequent piper in the woods throughout the summer and early fall.]--that also pipes occasionally in the woods.) I have discovered, also, that we have a musical spider.

One sunny April day, while seated on the borders of the woods, my attention was attracted by a soft, uncertain, purring sound that proceeded from the dry leaves at my feet. On investigating the matter, I found that it was made by a busy little spider. Several of them were traveling about over the leaves, as if in quest of some lost cue or secret. Every moment or two they would pause, and by some invisible means make the low, purring sound referred to.

Dr. J. A. Alien says the common turtle, or land tortoise, also has a note,--a loud, shrill, piping sound. It may yet be discovered that there is no silent creature in nature.

THE SAND HORNET

I turned another (to me) new page in natural history, when, during the past season, I made the acquaintance of the sand wasp or hornet. From boyhood I had known the black hornet, with his large paper nest, and the spiteful yellow-jacket, with his lesser domicile, and had cherished proper contempt for the various indolent wasps. But the sand hornet was a new bird,--in fact, the harpy eagle among insects,--and he made an impression. While walking along the road about midsummer, I noticed working in the towpath, where the ground was rather inclined to be dry and sandy, a large yellow hornet-like insect. It made a hole the size of one's little finger in the hard, gravelly path beside the roadbed. When disturbed, it alighted on the dirt and sand in the middle of the road. I had noticed in my walks some small bullet-like holes in the field that had piqued my curiosity, and I determined to keep an eye on these insects of the roadside. I explored their holes, and found them quite shallow, and no mystery at the bottom of them. One morning in the latter part of July, walking that way, I was quickly attracted by the sight of a row of little mounds of fine, freshly dug earth resting upon the gra.s.s beside the road, a foot or more beneath the path. "What is this?" I said. "Mice, or squirrels, or snakes," said my neighbor. But I connected it at once with the strange insect I had seen. Neither mice nor squirrels work like that, and snakes do not dig. Above each mound of earth was a hole the size of one's largest finger, leading into the bank. While speculating about the phenomenon, I saw one of the large yellow hornets I had observed quickly enter one of the holes. That settled the query. While spade and hoe were being brought to dig him out, another hornet appeared, heavy-laden with some prey, and flew humming up and down and around the place where I was standing.

I withdrew a little, when he quickly alighted upon one of the mounds of earth, and I saw him carrying into his den no less an insect than the cicada or harvest-fly. Then another came, and after coursing up and down a few times, disturbed by my presence, alighted upon a tree, with his quarry, to rest. The black hornet will capture a fly, or a small b.u.t.terfly, and, after breaking and dismembering it, will take it to his nest; but here was this hornet carrying an insect much larger than himself, and flying with ease and swiftness. It was as if a hawk should carry a hen, or an eagle a turkey. I at once proceeded to dig for one of the hornets, and, after following his hole about three feet under the footpath and to the edge of the roadbed, succeeded in capturing him and recovering the cicada. The hornet weighed fifteen grains, and the cicada nineteen; but in bulk the cicada exceeded the hornet by more than half. In color, the wings and thorax, or waist, of the hornet were a rich bronze; the abdomen was black, with three irregular yellow bands; the legs were large and powerful, especially the third or hindmost pair, which were much larger than the others, and armed with many spurs and hooks. In digging its hole the hornet has been seen at work very early in the morning. It backed out with the loosened material, like any other animal under the same circ.u.mstances, holding and sc.r.a.ping back the dirt with its legs.

The preliminary prospecting upon the footpath, which I had observed, seems to have been the work of the males, as it was certainly of the smaller hornets, and the object was doubtless to examine the ground, and ascertain if the place was suitable for nesting. By digging two or three inches through the hard, gravelly surface of the road, a fine sandy loam was discovered, which seemed to suit exactly, for in a few days the main shafts were all started in the greensward, evidently upon the strength of the favorable report which the surveyors had made. These were dug by the larger hornets or females. There was but one inhabitant in each hole, and the holes were two or three feet apart. One that we examined had nine chambers or galleries at the end of it, in each of which were two locusts, or eighteen in all. The locusts of the locality had suffered great slaughter. Some of them in the hole or den had been eaten to a mere sh.e.l.l by the larvae of the hornet. Under the wing of each insect an egg is attached; the egg soon hatches, and the grub at once proceeds to devour the food its thoughtful parent has provided. As it grows, it weaves itself a sort of sh.e.l.l or coc.o.o.n, in which, after a time, it undergoes its metamorphosis, and comes out, I think, a perfect insect toward the end of summer.

I understood now the meaning of that sudden cry of alarm I had so often heard proceed from the locust or cicada, followed by some object falling and rustling amid the leaves; the poor insect was doubtless in the clutches of this arch enemy. A number of locusts usually pa.s.sed the night on the under side of a large limb of a mulberry-tree near by: early one morning a hornet was seen to pounce suddenly upon one and drag it over on the top of the limb; a struggle ensued, but the locust was soon quieted and carried off.

It is said that the hornet does not sting the insect in a vital part,--for in that case it would not keep fresh for its young,--but introduces its poison into certain nervous ganglia, the injury to which has the effect of paralyzing the victim and making it incapable of motion, though life remains for some time.

My friend Van, who watched the hornets in my absence, saw a fierce battle one day over the right of possession of one of the dens. An angry, humming sound was heard to proceed from one of the holes; gradually it approached the surface, until the hornets emerged locked in each other's embrace, and rolled down the little embankment, where the combat was continued. Finally, one released his hold and took up his position in the mouth of his den (of course I should say SHE and HER, as these were the queen hornets), where she seemed to challenge her antagonist to come on. The other one manuvred about awhile, but could not draw her enemy out of her stronghold; then she clambered up the bank and began to bite and tear off bits of gra.s.s, and to loosen gravel-stones and earth, and roll them down into the mouth of the disputed pa.s.sage. This caused the besieged hornet to withdraw farther into her hole, when the other came down and thrust in her head, but hesitated to enter.

After more manuvering, the aggressor withdrew, and began to bore a hole about a foot from the one she had tried to possess herself of by force.

Besides the cicada, the sand hornet captures gra.s.shoppers and other large insects. I have never met with it before the present summer (1879), but this year I have heard of its appearance at several points along the Hudson.

THE SOLITARY BEE

If you "leave no stone unturned" in your walks through the fields, you may perchance discover the abode of one of our solitary bees.

Indeed, I have often thought what a chapter of natural history might be written on "Life under a Stone," so many of our smaller creatures take refuge there,--ants, crickets, spiders, wasps, b.u.mblebees, the solitary bee, mice, toads, snakes, and newts. What do these things do in a country where there are no stones? A stone makes a good roof, a good shield; it is water-proof and fire-proof, and, until the season becomes too rigorous, frost-proof too. The field mouse wants no better place to nest than beneath a large, flat stone, and the b.u.mblebee is entirely satisfied if she can get possession of his old or abandoned quarters. I have even heard of a swarm of hive bees going under a stone that was elevated a little from the ground. After that, I did not marvel at Samson's bees going into the carca.s.s or skeleton of the lion.

In the woods one day (it was November) I turned over a stone that had a very strange-looking creature under it,--a species of salamander I had never before seen, the banded salamander. It was five or six inches long, and was black and white in alternate bands. It looked like a creature of the night,--darkness dappled with moonlight,--and so it proved. I wrapped it up in some leaves and took it home in my pocket. By day it would barely move, and could not be stimulated or frightened into any activity; but an night it was alert and wide awake. Of its habits I know little, but it is a pretty and harmless creature. Under another stone was still another species, the violet-colored salamander, larger, of a dark plum-color, with two rows of bright yellow spots down its back. It evinced more activity than its fellow of the moon- bespattered garb. I have also found the little musical red newt under stones, and several small dark species.

But to return to the solitary bee. When you go a-hunting of the honey-bee, and are in quest of a specimen among the asters or goldenrod in some remote field to start a line with, you shall see how much this little native bee resembles her cousin of the social hive. There appear to be several varieties, but the one I have in mind is just the size of the honey-bee, and of the same general form and color, and its manner among the flowers is nearly the same. On close inspection, its color proves to be lighter, while the under side of its abdomen is of a rich bronze. The body is also flatter and less tapering, and the curve inclines upward, rather than downward. You perceive it would be the easiest thing in the world for the bee to sting an enemy perched upon its back.

One variety, with a bright buff abdomen, is called "sweat-bee" by the laborers in the field, because it alights upon their hands and bare arms when they are sweaty,--doubtless in quest of salt. It builds its nest in little cavities in rails and posts. But the one with the bronze or copper bottom builds under a stone. I discovered its nest one day in this wise: I was lying on the ground in a field, watching a line of honey-bees to the woods, when my attention was arrested by one of these native bees flying about me in a curious, inquiring way. When it returned the third time, I said, "That bee wants something of me," which proved to be the case, for I was lying upon the entrance to its nest. On my getting up, it alighted and crawled quickly home. I turned over the stone, which was less than a foot across, when the nest was partially exposed. It consisted of four cells, built in succession in a little tunnel that had been excavated in the ground. The cells, which were about three quarters of an inch long and half as far through, were made of sections cut from the leaf of the maple,-- cut with the mandibles of the bee, which work precisely like shears. I have seen the bee at work cutting out these pieces. She moves through the leaf like the hand of the tailor through a piece of cloth. When the pattern is detached, she rolls it up, and, embracing it with her legs, flies home with it, often appearing to have a bundle disproportionately large. Each cell is made up of a dozen or more pieces: the larger ones, those that form its walls, like the walls of a paper bag, are oblong, and are turned down at one end, so as to form the bottom; not one thickness of leaf merely, but three or four thicknesses, each fragment of leaf lapping over another. When the cell is completed, it is filled about two thirds full of bee-bread,--the color of that in the comb in the hive, but not so dry, and having a sourish smell. Upon this the egg is laid, and upon this the young feed when hatched. Is the paper bag now tied up? No, it is headed up; circular bits of leaves are nicely fitted into it to the number of six or seven.

They are cut without pattern or compa.s.s, and yet they are all alike, and all exactly fit. Indeed, the construction of this cell or receptacle shows great ingenuity and skill. The bee is, of course, unable to manage a single section of a leaf large enough, when rolled up, to form it, and so is obliged to construct it of smaller pieces, such as she can carry, lapping them one over another.

A few days later I saw a smaller species carrying fragments of a yellow autumn leaf under a stone in a cornfield. On examining the place about sundown to see if the bee lodged there, I found her snugly ensconced in a little rude cell that adhered to the under side of the stone. There was no pollen in it, and I half suspected it was merely a berth in which to pa.s.s the night.

These bees do not live even in pairs, but absolutely alone. They have large baskets on their legs in which to carry pollen, an article they are very industrious in collecting.

Why the larger species above described should have waited till October to build its nest is a mystery to me. Perhaps this was the second brood of the season, or can it be that the young were not to hatch till the following spring?

THE WEATHERWISE MUSKRAT

I am more than half persuaded that the muskrat is a wise little animal, and that on the subject of the weather, especially, he possesses some secret that I should be glad to know. In the fall of 1878 I noticed that he built unusually high and ma.s.sive nests.

I noticed them in several different localities. In a shallow, sluggish pond by the roadside, which I used to pa.s.s daily in my walk, two nests were in process of construction throughout the month of November. The builders worked only at night, and I could see each day that the work had visibly advanced. When there was a slight skim of ice over the pond, this was broken up about the nests, with trails through it in different directions where the material had been brought. The houses were placed a little to one side of the main channel, and were constructed entirely of a species of coa.r.s.e wild gra.s.s that grew all about. So far as I could see, from first to last they were solid ma.s.ses of gra.s.s, as if the interior cavity or nest was to be excavated afterward, as doubtless it was. As they emerged from the pond they gradually a.s.sumed the shape of a miniature mountain, very bold and steep on the south side, and running down a long, gentle grade to the surface of the water on the north. One could see that the little architect hauled all his material up this easy slope, and thrust it out boldly around the other side. Every mouthful was distinctly defined. After they were two feet or more above the water, I expected each day to see that the finishing stroke had been given and the work brought to a close. But higher yet, said the builder.

December drew near, the cold became threatening, and I was apprehensive that winter would suddenly shut down upon those unfinished nests. But the wise rats knew better than I did; they had received private advices from headquarters, that I knew not of.

Finally, about the 6th of December, the nests a.s.sumed completion; the northern incline was absorbed or carried up, and each structure became a strong, ma.s.sive cone, three or four feet high, the largest nest of the kind I had ever seen. Does it mean a severe winter? I inquired. An old farmer said it meant "high water," and he was right once, at least, for in a few days afterward we had the heaviest rainfall known in this section for half a century. The creeks rose to an almost unprecedented height. The sluggish pond became a seething, turbulent water-course; gradually the angry element crept up the sides of these lake dwellings, till, when the rain ceased, about four o'clock, they showed above the flood no larger than a man's hat. During the night the channel shifted till the main current swept over them, and next day not a vestige of the nests was to be seen; they had gone downstream, as had many other dwellings of a less temporary character. The rats had built wisely, and would have been perfectly secure against any ordinary high water, but who can foresee a flood? The oldest traditions of their race did not run back to the time of such a visitation.

Nearly a week afterward another dwelling was begun, well away from the treacherous channel, but the architects did not work at it with much heart: the material was very scarce, the ice hindered; and before the bas.e.m.e.nt story was fairly finished, Winter had the pond under his lock and key.

In other localities I noticed that, where the nests were placed on the banks of streams, they were made secure against the floods by being built amid a small clump of bushes. When the fall of 1879 came, the muskrats were very tardy about beginning their house, laying the corner-stone--or the corner-sod--about December 1, and continuing the work slowly and indifferently. On the 15th of the month the nest was not yet finished. This, I said, indicates a mild winter; and, sure enough, the season was one of the mildest known for many years. The rats had little use for their house.

Again, in the fall of 1880, while the weather-wise were wagging their heads, some forecasting a mild, some a severe winter, I watched with interest for a sign from my muskrats. About November 1, a month earlier than the previous year, they began their nest, and worked at it with a will. They appeared to have just got tidings of what was coming. If I had taken the hint so palpably given, my celery would not have been frozen up in the ground, and my apples caught in unprotected places. When the cold wave struck us, about November 20, my four-legged "I-told-you-so's" had nearly completed their dwelling; it lacked only the ridge-board, so to speak; it needed a little "topping out," to give it a finished look. But this it never got. The winter had come to stay, and it waxed more and more severe, till the unprecedented cold of the last days of December must have astonished even the wise muskrats in their snug retreat. I approached their nest at this time, a white mound upon the white, deeply frozen surface of the pond, and wondered if there was any life in that apparent sepulchre. I thrust my walking-stick sharply into it, when there was a rustle and a splash into the water, as the occupant made his escape. What a damp bas.e.m.e.nt that house has, I thought, and what a pity to rout a peaceful neighbor out of his bed in this weather, and into such a state of things as this! But water does not wet the muskrat; his fur is charmed, and not a drop penetrates it.

Where the ground is favorable, the muskrats do not build these mound-like nests, but burrow into the bank a long distance, and establish their winter-quarters there.

Shall we not say, then, in view of the above facts, that this little creature is weatherwise? The hitting of the mark twice might be mere good luck; but three bull's-eyes in succession is not a mere coincidence; it is a proof of skill. The muskrat is not found in the Old World, which is a little singular, as other rats so abound there, and as those slow-going English streams especially, with their gra.s.sy banks, are so well suited to him. The water-rat of Europe is smaller, but of similar nature and habits. The muskrat does not hibernate like some rodents, but is pretty active all winter. In December I noticed in my walk where they had made excursions of a few yards to an orchard for frozen apples. One day, along a little stream, I saw a mink track amid those of the muskrat; following it up, I presently came to blood and other marks of strife upon the snow beside a stone wall. Looking in between the stones, I found the carca.s.s of the luckless rat, with its head and neck eaten away. The mink had made a meal of him.

CHEATING THE SQUIRRELS

For the largest and finest chestnuts I had last fall I was indebted to the gray squirrels. Walking through the early October woods one day, I came upon a place where the ground was thickly strewn with very large unopened chestnut burrs. On examination, I found that every burr had been cut square off with about an inch of the stem adhering, and not one had been left on the tree. It was not accident, then, but design. Whose design? The squirrels'. The fruit was the finest I had ever seen in the woods, and some wise squirrel had marked it for his own. The burrs were ripe, and had just begun to divide, not "threefold," but fourfold, "to show the fruit within." The squirrel that had taken all this pains had evidently reasoned with himself thus: "Now, these are extremely fine chestnuts, and I want them; if I wait till the burrs open on the tree, the crows and jays will be sure to carry off a great many of the nuts before they fall; then, after the wind has rattled out what remain, there are the mice, the chipmunks, the red squirrels, the racc.o.o.ns, the grouse, to say nothing of the boys and the pigs, to come in for their share; so I will forestall events a little: I will cut off the burrs when they have matured, and a few days of this dry October weather will cause every one of them to open on the ground; I shall be on hand in the nick of time to gather up my nuts." The squirrel, of course, had to take the chances of a prowler like myself coming along, but he had fairly stolen a march on his neighbors. As I proceeded to collect and open the burrs, I was half prepared to hear an audible protest from the trees about, for I constantly fancied myself watched by shy but jealous eyes.

It is an interesting inquiry how the squirrel knew the burrs would open if left to lie on the ground a few days. Perhaps he did not know, but thought the experiment worth trying.

The gray squirrel is peculiarly an American product, and might serve very well as a national emblem. The Old World can beat us on rats and mice, but we are far ahead on squirrels, having five or six species to Europe's one.

THE SKYLARK ON THE HUDSON

My note-book of the past season is enriched with the unusual incident of an English skylark in full song above an Esopus meadow.

I was poking about a marshy place in a low field one morning in early May, when, through the maze of bird-voices,--laughter of robins, call of meadowlarks, song of bobolinks, ditty of sparrows, whistle of orioles, twitter of swallows,--with which the air was filled, my ear suddenly caught an unfamiliar strain. I paused to listen: can it be possible, I thought, that I hear a lark, or am I dreaming? The song came from the air, above a wide, low meadow many hundred yards away. Withdrawing a few paces to a more elevated position, I bent my eye and ear eagerly in that direction. Yes, that unstinted, jubilant, skyward, mult.i.tudinous song can be none other than the lark's! Any of our native songsters would have ceased while I was listening. Presently I was fortunate enough to catch sight of the bird. He had reached his climax in the sky, and was hanging with quivering wings beneath a small white cloud, against which his form was clearly revealed. I had seen and heard the lark in England, else I should still have been in doubt about the ident.i.ty of this singer. While I was climbing a fence I was obliged to take my eye from the bird, and when I looked again the song had ceased and the lark had gone. I was soon in the meadow above which I had heard him, and the first bird I flushed was the lark.

How strange he looked to my eye (I use the masculine gender because it was a male bird, but an Irishman laboring in the field, to whom I related my discovery, spoke touchingly of the bird as "she," and I notice that the old poets do the same); his long, sharp wings, and something in his manner of flight suggested a sh.o.r.e-bird. I followed him about the meadow and got several s.n.a.t.c.hes of song out of him, but not again the soaring, skyward flight and copious musical shower. By appearing to pa.s.s by, I several times got within a few yards of him; as I drew near he would squat in the stubble, and then suddenly start up, and, when fairly launched, sing briefly till he alighted again fifteen or twenty rods away. I came twice the next day and twice the next, and each time found the lark in the meadow or heard his song from the air or the sky.

What was especially interesting was that the lark had "singled out with affection" one of our native birds, and the one that most resembled its kind, namely, the vesper sparrow, or gra.s.s finch. To this bird I saw him paying his addresses with the greatest a.s.siduity. He would follow it about and hover above it, and by many gentle indirections seek to approach it. But the sparrow was shy, and evidently did not know what to make of her distinguished foreign lover. It would sometimes take refuge in a bush, when the lark, not being a percher, would alight upon the ground beneath it.

This sparrow looks enough like the lark to be a near relation. Its color is precisely the same, and it has the distinguishing mark of the two lateral white quills in its tail. It has the same habit of skulking in the stubble or the gra.s.s as you approach; it is exclusively a field-bird, and certain of its notes might have been copied from the lark's song. In size it is about a third smaller, and this is the most marked difference between them. With the n.o.bler bipeds, this would not have been any obstacle to the union, and in this case the lark was evidently quite ready to ignore the difference, but the sparrow persisted in saying him nay. It was doubtless this obstinacy on her part that drove the lark away, for, on the fifth day, I could not find him, and have never seen nor heard him since. I hope he found a mate somewhere, but it is quite improbable. The bird had, most likely, escaped from a cage, or, maybe, it was a survivor of a number liberated some years ago on Long Island. There is no reason why I the lark should not thrive in this country as well as in Europe, and, if a few hundred were liberated in any of our fields in April or May, I have little doubt they would soon become established. And what an acquisition it would be! As a songster, the lark is deserving of all the praise that has been bestowed upon him. He would not add so much to the harmony or melody of our bird-choir as he would add to its blithesomeness, joyousness, and power. His voice is the jocund and inspiring voice of a spring morning. It is like a ceaseless and hilarious clapping of hands. I was much interested in an account a friend gave me of the first skylark he heard while abroad. He had been so full of the sights and wonders of the Old World that he had quite forgotten the larks, when one day, as he was walking somewhere near the sea, a brown bird started up in front of him, and mounting upward began to sing. It drew his attention, and as the bird went skyward, pouring out his rapid and jubilant notes, like bees from a hive in swarming-time, the truth suddenly flashed upon the observer.

"Good heavens!" he exclaimed, "that is a skylark; there is no mistaking that bird."

It is this unique and unmistakable character of the lark's song, and its fountain-like sparkle and copiousness, that are the main sources of its charm.

NOCTURNAL INSECTS

How the nocturnal insects, the tree-crickets and katydids, fail as the heat fails! They are musicians that play fast or slow, strong or feeble, just as the heat of the season waxes or wanes; and they play as long as life lasts: when their music ceases, they are dead.

The katydids begin in August, and cry with great vigor and spirit, "Katy-did," "Katydid," or "Katy-did n't." Toward the last of September they have taken in sail a good deal, and cry simply, "Katy," "Katy," with frequent pauses and resting-spells. In October they languidly gasp or rasp, "Kate," "Kate," "Kate," and before the end of the month they become entirely inaudible, though I suspect that if one's ear were sharp enough he might still hear a dying whisper, "Kate," "Kate." Those cousins of Katy, the little green purring tree-crickets, fail in the same way and at the same time. When their chorus is fullest, the warm autumn night fairly throbs with the soft lulling undertone. I notice that the sound is in waves or has a kind of rhythmic beat. What a gentle, un.o.btrusive background it forms for the sharp, reedy notes of the katydids! As the season advances, their life ebbs and ebbs: you hear one here and one there, but the air is no longer filled with that regular pulse-beat of sound. One by one the musicians cease, till, perhaps on some mild night late in October, you hear--just hear and that is all--the last feeble note of the last of these little harpers.

LOVE AND WAR AMONG THE BIRDS

In the spring movements of the fishes up the stream, toward their sp.a.w.ning-beds, the females are the pioneers, appearing some days in advance of the males. With the birds the reverse is the case, the males coming a week or ten days before the females. The female fish is usually the larger and stronger, and perhaps better able to take the lead; among most reptiles the same fact holds, and throughout the insect world there is to my knowledge no exception to the rule. Among the birds, the only exception I am aware of is in the case of the birds of prey. Here the female is the larger and stronger. If you see an exceptionally large and powerful eagle, rest a.s.sured the s.e.x is feminine. But higher in the scale the male comes to the front and leads in size and strength.

But the first familiar spring birds are c.o.c.ks; hence the songs and tilts and rivalries. Hence also the fact that they are slightly in excess of the other s.e.x, to make up for this greater exposure; apparently no courting is done in the South, and no matches are prearranged. The males leave irregularly without any hint, I suspect, to the females as to when and where they will meet them.

In the case of the pa.s.senger pigeon, however, the two s.e.xes travel together, as they do among the migrating water-fowls.
