YELLOW-BELLIED FLYCATCHER (Empidonax flaviventris) Flycatcher family

Length -- 5 to 5.6 inches. About an inch smaller than the English sparrow.

Male -- Rather dark, but true olive-green above. Throat and breast yellowish olive, shading into pale yellow underneath, including wing linings and under tail coverts. Wings have yellowish bars. Whitish ring around eye. Upper part of bill black, under part whitish or flesh-colored.

Female -- Smaller, with brighter yellow under parts and more decidedly yellow wing-bars.

Range -- North America, from Labrador to Panama, and westward from the Atlantic to the plains. Winters in Central America.

Migrations -- May. September. Summer resident. More commonly a migrant only.

This is the most yellow of the small flycatchers and the only Eastern species with a yellow instead of a white throat. Without hearing its call-note, "pse-ek-pse-ek," which it abruptly sneezes rather than utters, it is quite impossible, as it darts among the trees, to tell it from the Acadian flycatcher, with which even Audubon confounded it. Both these little birds choose the same sort of retreats -- well-timbered woods near a stream that attracts myriads of insects to its spongy sh.o.r.es -- and both are rather shy and solitary. The yellow-bellied species has a far more northerly range, however, than its Southern relative or even the small green-crested flycatcher. It is rare in the Middle States, not common even in New England, except in the migrations, but from the Canada border northward its soft, plaintive whistle, which is its love-song, may be heard in every forest where it nests. All the flycatchers seem to make a noise with so much struggle, such convulsive jerkings of head and tail, and flutterings of the wings that, considering the scanty success of their musical attempts, it is surprising they try to lift their voices at all when the effort almost literally lifts them off their feet.

While this little flycatcher is no less erratic than its Acadian cousin, its nest is never slovenly. One couple had their home in a wild-grape bower in Pennsylvania; a Virginia creeper in New Jersey supported another cradle that was fully twenty feet above the ground; but in Labrador, where the bird has its chosen breeding grounds, the bulky nest is said to be invariably placed either in the moss by the brookside or in some old stump, should the locality be too swampy.

BLACK-THROATED GREEN WARBLER (Dendroica virens) Wood Warbler family

Length -- 5 inches. Over an inch smaller than the English sparrow.

Male -- Back and crown of head bright yellowish olive-green.

Forehead, band over eye, cheeks, and sides of neck rich yellow.

Throat, upper breast, and stripe along sides black. Underneath yellowish white. Wings and tail brownish olive, the former with two white bars, the latter with much white in outer quills. In autumn, plumage resembling the female's.

Female -- Similar; chin yellowish; throat and breast dusky, the black being mixed with yellowish.

Range -- Eastern North America, from Hudson Bay to Central America and Mexico. Nests north of Illinois and New York.

Winters in tropics.

Migrations -- May. October. Common summer resident north of New Jersey.

There can be little difficulty in naming a bird so brilliantly and distinctly marked as this green, gold, and black warbler, that lifts up a few pure, sweet, tender notes, loud enough to attract attention when he visits the garden. "See-see, see-saw," he sings, but there is a tone of anxiety betrayed in the simple, sylvan strain that always seems as if the bird needed rea.s.suring, possibly due to the rising inflection, like an interrogative, of the last notes.

However abundant about our homes during the migrations, this warbler, true to the family instinct, retreats to the woods to nest -- not always so far away as Canada, the nesting ground of most warblers, for in many Northern States the bird is commonly found throughout the summer. Doubtless it prefers tall evergreen trees for its mossy, gra.s.sy nest; but it is not always particular, so that the tree be a tall one with a convenient fork in an upper branch.

Early in September increased numbers emerge from the woods, the plumage of the male being less brilliant than when we saw it last, as if the family cares of the summer had proved too taxing. For nearly a month longer they hunt incessantly, with much flitting about the leaves and twigs at the ends of branches in the shrubbery and evergreens, for the tiny insects that the warblers must devour by the million during their all too brief visit.

BIRDS CONSPICUOUSLY YELLOW AND ORANGE

YELLOW-THROATED VIREO (Vireo flavifrons) Vireo or Greenlet family

Length -- 5.5. to 6 inches. A little smaller than the English sparrow.

Male and Female -- Lemon-yellow on throat, upper breast; line around the eye and forehead. Yellow, shading into olive-green, on head, back, and shoulders. Underneath white. Tail dark brownish, edged with white. Wings a lighter shade, with two white bands across, and some quills edged with white.

Range -- North America, from Newfoundland to Gulf of Mexico, and westward to the Rockies. Winters in the tropics.

Migrations -- May. September. Spring and autumn migrant; more rarely resident.

This is undoubtedly the beauty of the vireo family -- a group of neat, active, stoutly built, and vigorous little birds of yellow, greenish, and white plumage; birds that love the trees, and whose feathers reflect the coloring of the leaves they hide, hunt, and nest among. "We have no birds," says Bradford Torrey, "so unsparing of their music: they sing from morning till night."

The yellow-throated vireo partakes of all the family characteristics, but, in addition to these, it eclipses all its relatives in the brilliancy of its coloring and in the art of nest-building, which it has brought to a state of hopeless perfection. No envious bird need try to excel the exquisite finish of its workmanship. Happily, it has wit enough to build its pensile nest high above the reach of small boys, usually suspending it from a branch overhanging running water that threatens too precipitous a bath to tempt the young climbers.

However common in the city parks and suburban gardens this bird may be during the migrations, it delights in a secluded retreat overgrown with tall trees and near a stream, such as is dear to the solitary vireo as well when the nesting time approaches. High up in the trees we hear its rather sad, persistent strain, that is more in harmony with the dim forest than with the gay flower garden, where, if the truth must be told, its song is both monotonous and depressing. Mr. Bicknell says it is the only vireo that sings as it flies.

AMERICAN GOLDFINCH (Spinus tristis) Finch family

Called also: WILD CANARY; YELLOWBIRD; THISTLE BIRD

Length -- 5 to 5.2 inches. About an inch smaller than the English sparrow.

Male -- In summer plumage: Bright yellow, except on crown of head, frontlet, wings, and tail, which are black. Whitish markings on wings give effect of bands. Tail with white on inner webs. In winter plumage: Head yellow-olive; no frontlet; black drab, with reddish tinge; shoulders and throat yellow; soiled brownish white underneath.

Female -- Brownish olive above, yellowish white beneath.

Range -- North America, from the tropics to the Fur Countries and westward to the Columbia River and California. Common throughout its range.

Migrations -- May-October. Common summer resident, frequently Seen throughout the winter as well.

An old field, overgrown with thistles and tall, stalky wild flowers, is the paradise of the goldfinches, summer or winter. Here they congregate in happy companies while the sunshine and goldenrod are as bright as their feathers, and cling to the swaying slender stems that furnish an abundant harvest, daintily. lunching upon the fluffy seeds of thistle blossoms, pecking at the mullein-stalks, and swinging airily among the asters and Michaelmas daisies; or, when snow covers the same field with a glistening crust, above which the brown stalks offer only a meagre dinner, the same birds, now sombrely clad in winter feathers, cling to the swaying stems with cheerful fort.i.tude.

At your approach, the busy company rises on the wing, and with peculiar, wavy flight rise and fall through the air, marking each undulation with a cl.u.s.ter of notes, sweet and clear, that come floating downward from the blue ether, where the birds seem to bound along exultant in their motion and song alike.

In the spring the plumage of the goldfinch, which has been drab and brown through the winter months, is moulted or shed -- a change that transforms the bird from a sombre Puritan into the gayest of cavaliers, and seems to wonderfully exalt his spirits. He bursts into a wild, sweet, incoherent melody that might be the outpouring from two or three throats at once instead of one, expressing his rapture somewhat after the manner of the canary, although his song lacks the variety and the finish of his caged namesake. What tone of sadness in his music the man found who applied the adjective tristis to his scientific name it is difficult to imagine when listening to the notes that come bubbling up from the bird's happy heart.

With plumage so lovely and song so delicious and dreamy, it is small wonder that numbers of our goldfinches are caught and caged, however inferior their song may be to the European species recently introduced into this country.

Heard in Central Park, New York, where they were set at liberty, the European goldfinches seemed to sing with more abandon, perhaps, but with no more sweetness than their American cousins. The song remains at its best all through the summer months, for the bird is a long wooer. It is nearly July before he mates, and not until the tardy cedar birds are house-building in the orchard do the happy pair begin to carry gra.s.s, moss, and plant-down to a crotch of some tall tree convenient to a field of such wild flowers as will furnish food to a growing family. Doubtless the birds wait for this food to be in proper condition before they undertake parental duties at all -- the most plausible excuse for their late nesting. The cares evolving from four to six pale-blue eggs will suffice to quiet the father's song for the winter by the first of September, and fade all the glory out of his shining coat. As pretty a sight as any garden offers is when a family of goldfinches alights on the top of a sunflower to feast upon the oily seeds -- a perfect harmony of brown and gold.

EVENING GROSBEAK (Coccothraustes vespertinus) Finch family

Length -- 8 inches. Two inches shorter than the robin.

Male -- Forehead, shoulders, and underneath clear yellow: dull yellow on lower back; sides of the head, throat, and breast olive-brown. Crown, tail, and wings black, the latter with white secondary feathers. Bill heavy and blunt, and yellow.

Female -- Brownish gray, more less suffused with yellow. Wings and tail blackish, with some white feathers.

Range -- Interior of North America. Resident from Manitoba northward. Common winter visitor in northwestern United States and Mississippi Valley; casual winter visitor in northern Atlantic States.

In the winter of 1889-90 Eastern people had the rare treat of becoming acquainted with this common bird of the Northwest, that, in one of its erratic travels, chose to visit New England and the Atlantic States, as far south as Delaware, in great numbers. Those who saw the evening grosbeaks then remember how beautiful their yellow plumage -- a rare winter tint -- looked in the snow-covered trees, where small companies of the gentle and ever tame visitors enjoyed the buds and seeds of the maples, elders, and evergreens. Possibly evening grosbeaks were in vogue for the next season's millinery, or perhaps Eastern ornithologists had a sudden zeal to investigate their structural anatomy. At any rate, these birds, whose very tameness, that showed slight acquaintance with mankind, should have touched the coldest heart, received the warmest kind of a reception from hot shot. The few birds that escaped to the solitudes of Manitoba could not be expected to tempt other travellers eastward by an account of their visit. The bird is quite likely to remain rare in the East.

But in the Mississippi Valley and throughout the northwest, companies of from six to sixty may be regularly counted upon as winter neighbors on almost every farm. Here the females keep up a busy chatting, like a company of cedar birds, and the males punctuate their pauses with a single shrill note that gives little indication of their vocal powers. But in the solitude of the northern forests the love-song is said to resemble the robin's at the start. Unhappily, after a most promising beginning, the bird suddenly stops, as if he were out of breath.

BLUE-WINGED WARBLER (Helminthophila pinus) Wood Warbler family

Called also: BLUE-WINGED YELLOW WARBLER

Length -- 4.75 inches. An inch and a half shorter than the English sparrow.

Male -- Crown of head and all under parts bright yellow. Back olive-green. Wings and tail bluish slate, the former with white bars, and three outer tail quills with large white patches on their inner webs.

Female -- Paler and more olive.

Range -- Eastern United States, from southern New England and Minnesota, the northern limit of its nesting range, to Mexico And Central America, where it winters.

Migrations -- May. September. Summer resident.

In the naming of warblers, bluish slate is the shade intended when blue is mentioned; so that if you see a dainty little olive and yellow bird with slate-colored wings and tail hunting for spiders in the blossoming orchard or during the early autumn you will have seen the beautiful blue-winged warbler.

It has a rather leisurely way of hunting, unlike the nervous, restless flitting about from twig to twig that is characteristic of many of its many cousins. The search is thorough -- bark, stems, blossoms, leaves are inspected for larvae and spiders, with many pretty motions of head and body. Sometimes, hanging with head downward, the bird suggests a yellow t.i.tmouse. After blossom time a pair of these warblers, that have done serviceable work in the orchard in their all too brief stay, hurry off to dense woods to nest. They are usually to be seen in pairs at all seasons. Not to "high coniferous trees in northern forests," -- the Mecca of innumerable warblers -- but to scrubby, second growth of woodland borders, or lower trees in the heart of the woods, do these dainty birds retreat. There they build the usual warbler nest of twigs, bits of bark, leaves, and gra.s.ses, but with this peculiarity: the numerous leaves with which the nest is wrapped all have their stems pointing upward. Mr. Frank Chapman has admirably defined their song as consisting of "two drawled, wheezy notes -- swee-chee, the first inhaled, the second exhaled."
