SHORT-BILLED MARSH WREN (Cistothorus stellaris) Wren family

[Called also: SEDGE WREN, AOU 1998]

Length -- 4 to 5 inches. Actually about one-third smaller than

the English sparrow, but apparently only half its size.

Male and Female -- Brown above, faintly streaked with white,

black, and buff. Wings and tail barred with same. Underneath

white, with buff and rusty tinges on throat and breast. Short

bill.

Range -- North America, from Manitoba southward in winter to Gulf

of Mexico. Most common in north temperate latitudes.

Migrations -- Early May. Late September.

Where red-winged blackbirds like to congregate in oozy pastures or near boggy

woods, the little short-billed wren may more often be heard than seen, for he

is more shy, if possible, than his long-billed cousin, and will dive down into

the sedges at your approach, very much as a duck disappears under water. But

if you see him at all, it is usually while swaying to and fro as he clings to

some tall stalk of grass, keeping his balance by the nervous, jerky tail

motions characteristic of all the wrens, and singing with all his might.

Oftentimes his tail reaches backward almost to his head in a most exaggerated

wren-fashion.

Samuels explains the peculiar habit both the long-billed and the short-billed

marsh wrens have of building several nests in one season, by the theory that

they are made to protect the sitting female, for it is noticed that the male

bird always lures a visitor to an empty nest, and if this does not satisfy his

curiosity, to another one, to prove conclusively that he has no family in

prospect.

Wild rice is an ideal nesting place for a colony of these little marsh wrens.

The home is made of sedge grasses, softly lined with the softer meadow grass

or plant-down, and placed in a tussock of tall grass, or even upon the ground.

The entrance is on the side. But while fond of moist places, both for a home

and feeding ground, it will be noticed that these wrens have no special

fondness for running water, so dear to their long-billed relatives. Another

distinction is that the eggs of this species, instead of being so densely

speckled as to look brown, are pure white.

BROWN THRASHER (Harporhynchus rufus) Thrasher and Mocking-bird

family

Called also: BROWN THRUSH; GROUND THRUSH; RED THRUSH; BROWN

MOCKING-BIRD; FRENCH MOCKING-BIRD; MAVIS

Length -- 11 to 11.5 inches. Fully an inch longer than the robin.

Male -- Rusty red-brown or rufous above; darkest on wings, which

have two short whitish bands. Underneath white, heavily

streaked (except on throat) with dark-brown, arrow-shaped

spots. Tail very long. Yellow eyes. Bill long and curved at

tip.

Female -- Paler than male.

Range -- United States to Rockies. Nests from Gulf States to

Manitoba and Montreal. Winters south of Virginia.

Migrations -- Late April. October. Common summer resident

"There's a merry brown thrush sitting up in a tree;

He is singing to me! He is singing to me!

And what does he say, little girl, little boy?

'Oh, the world's running over with joy!'"

The hackneyed poem beginning with this stanza that delighted our nursery days,

has left in our minds a fairly correct impression of the bird. He still proves

to be one of the perennially joyous singers, like a true cousin of the wrens,

and when we study him afield, he appears to give his whole attention to his

song with a self-consciousness that is rather amusing than the reverse. "What

musician wouldn't be conscious of his own powers," he seems to challenge us,

"if he possessed such a gift?" Seated on a conspicuous perch, as if inviting

attention to his performance, with uplifted head and drooping tail he repeats

the one exultant, dashing air to which his repertoire is limited, without

waiting for an encore. Much practice has given the notes a brilliancy of

execution to be compared only with the mockingbird's; but in spite of the name

"ferruginous mocking-bird" that Audubon gave him, he does not seem to have the

faculty of imitating other birds' songs. Thoreau says the Massachusetts

farmers, when planting their seed, always think they hear the thrasher say,

"Drop it, drop it -- cover it up, cover it up -- pull it up, pull it up, pull

it up."

One of the shatterings of childish impressions that age too often brings is

when we learn by the books that our "merry brown thrush" is no thrush at all,

but a thrasher -- first cousin to the wrens, in spite of his speckled breast,

large size, and certain thrush-like instincts, such as never singing near the

nest and shunning mankind in the nesting season, to mention only two.

Certainly his bold, swinging flight and habit of hopping and running over the

ground would seem to indicate that he is not very far removed from the true

thrushes. But he has one undeniable wren-like trait, that of twitching,

wagging, and thrashing his long tail about to help express his emotions. It

swings like a pendulum as he rests on a branch, and thrashes about in a most

ludicrous way as he is feeding on the ground upon the worms, insects, and

fruit that constitute his diet.

Before the fatal multiplication of cats, and in unfrequented, sandy locations

still, the thrasher builds her nest upon the ground, thus earning the name

"ground thrush" that is often given her; but with dearly paid-for wisdom she

now most frequently selecting a low shrub or tree to cradle the two broods

that all too early in the summer effectually silence the father's delightful

song.
