FEBRUARY.

But Winter has yet brighter scenes—he boasts

Splendors beyond what gorgeous summer knows;

Or Autumn with his many fruits, and woods

All flushed with many hues. Come when the rains

Have glazed the snow and clothed the trees with ice,

While the slant sun of February pours

Into the bowers a flood of light. Approach!

The incrusted surface shall upbear thy steps,

And the broad arching portals of the grove

Welcome thy entering. Look! the massy trunks

Are cased in the pure crystal; each light spray,

Nodding and tinkling in the breath of heaven,

Is studded with its trembling water-drops,

That glimmer with an amethystine light.

But round the parent-stem the long low boughs

Bend, in a glittering ring, and arbors hide

The glassy floor. Oh! you might deem the spot

The spacious cavern of some virgin mine,

Deep in the womb of earth—where the gems grow,

And diamonds put forth radiant rods and bud

While amethyst and topaz—and the place

Lit up, most royally, with the pure beam

That dwells in them. * * * *

THE BLUE-HEADED VIREO.

(_Vireo solitarius._)

The Blue-headed Vireo, or its varieties, of which there are several,

frequent nearly the whole of North America. The typical form of the

species, that of our illustration, has a range covering Eastern North

America and extending westward to the great plains. It breeds from

Southern New England and the lake states northward to Hudson Bay and

southward in the higher altitudes of the Alleghenies. It passes the

winter in Cuba, Mexico and Central America. The Blue-headed Vireo is

frequently called the Solitary Vireo, or Greenlet, because of its

retiring habits. It is a bird of the forest and stays very close in

these quiet retreats. Yet it is, as a rule, easy of approach, seeming to

possess both curiosity and confidence. Mr. Bradford Torrey writes with

enthusiasm regarding the pretty habits of this bird. He says: “Its most

winning trait is its tameness. Wood bird as it is, it will sometimes

permit the greatest familiarities. Two birds I have seen which allowed

themselves to be stroked in the freest manner while sitting on the eggs,

and which ate from my hand as readily as any pet canary; but I have seen

others that complained loudly whenever I approached their tree. Perhaps

they had had sad experiences.”

Possessing a happy and cheerful disposition, this species, like the

other vireos, sings while working. Listening to them, we are reminded of

the lines in “The Vision of Sir Launfal”—

“The little birds sang as if it were

The one day of summer in all the year,

And the very leaves seemed to sing on the trees.”

Fortunate, indeed, is he who has the pleasure of watching this Vireo

working upon its home and uttering “inexpressibly sweet and tender love

notes.”

Mr. Thomas M. Brewer says that the Blue-headed Vireo “usually makes a

nest of coarse materials somewhat loosely put together, covering it with

lichens, thus assimilating it to the moss-covered limb from which it is

suspended.” The materials used, however, are not always the same. One

nest, of which Mr. Brewer speaks, was “covered over, as if cemented,

with bits of newspaper.” The external portion of another was “composed

of the silky cover of cocoons, woven into a homogeneous and clothlike

fabric, by some process quite inexplicable.” The nests are frequently

constructed of fine bark fibers, withered grass and pine needles woven

together with moss and lined with plant down, fine grass and small,

fibrous roots.

Much has been written regarding the song of this handsome bird of the

woods. The words of Mr. Torrey perhaps best describe it. He says: “The

Solitary’s song is matchless for the tenderness of its cadence, while in

peculiarly happy moments the bird indulges in a continuous warble that

is really enchanting.” It has, too, a musical chatter and a pretty

trilled whistle.

In Mr. Keyser’s experience “the song was varied and lively, sometimes

running high in the scale, and had not that absent-minded air which

marks the roundelay of the warbling vireo. It is much more intense and

expressive.”

Mr. Brewer describes the song as a “prolonged and very peculiar ditty,

repeated at frequent intervals and always identical. It begins with a

lively and pleasant warble, of a gradually ascending scale, which at a

certain pitch suddenly breaks down into a falsetto note. The song then

rises again in a single note and ceases.”

The notes of the female suggest to Mr. Burroughs “the bleating of a tiny

lambkin.” To Mr. Nuttall “its song seems to be intermediate between that

of the red-eyed and the yellow-breasted species, having the ‘preai,

preai,’ of the latter and the fine variety of the former in its tones.”

To all “the music of the Solitary Vireo is delicious.”
