Citizen Bird Part 20

WOODLAND WARBLERS

"Now you may be introduced to a family of American birds, many of them brightly colored and none of them large, who have no cousins or relations in any other country. You must not expect them to come and peep in the window like the Catbird, or feed on the lawn like the Thrush and Robin; for they are birds of woodland and brushland. Yet the often come for a time in their journeys to gardens and orchards, for they are among the greatest travellers."

"Why do they travel so much, if they are only American birds?" asked Nat. "I shouldn't think they would have to go far if they always live in America."

"America is a very large country, my boy, and you must not forget it includes South as well as North America--the Western Hemisphere of the whole globe. Warblers are insect-eating Citizens and cannot live long on anything else. Now, as many of them nest far North, when the early frosts lock the country they must often make long journeys at short notice, until they find their insect food again."

"Why don't we see swarms and swarms of them flying by?" asked Dodo.

"You mean flocks," said Olive; "we only say 'swarms' when we mean bees or other insects." "They make their journeys mostly by night,"

continued the Doctor, "for darkness protects their bright colors from the cannibal birds and various other enemies. One day there will not be a single Warbler in the river woods, and the next the trees will be bright with them.

"Another reason that we do not commonly see these Warblers is, that the greatest number do not come from the South until the trees are in leaf, and they pa.s.s back again through the middle portions of the States before the trees are bare in autumn, so that they easily hide from us."

"Are there no bright-colored birds that live all winter where the trees are bare?" asked Rap.

"Yes, three--the Cardinal, the Crossbill, and the Pine Grosbeak. They are seed-eating birds, and all belong to the Sparrow family. Most of the very showy birds belong to tropical countries, where the trees are always in leaf and there are quant.i.ties of orchids and other conspicuous flowers to attract the eye from the birds themselves.

"This habit of travelling by night has caused a great many of these beautiful Warblers to lose their lives, for they often fly against telegraph wires, high steeples, and lighthouse towers, and are killed.

Another danger also besets them--they may come from the South with a bit of early mild weather, and nearing the Great Lakes meet a storm from the North, and the food-supply being very scanty, the icy winds overcome their strength.

"A friend of mine who lives in Wisconsin," continued the Doctor, "has a garden that slopes down to Geneva Lake. Late one April there came a windstorm from the northwest, and the next morning the lawn was strewn with the bodies of hundreds of little Warblers who had become confused in the darkness and unable to reach shelter.

"You see how many troubles and risks Citizen Bird has to endure at best, so that we House People should do everything we can to protect him and make his life among us happy.

"You will have more use for your eyes than your ears, in naming the Warblers. Their plumage is almost always striking, but their voices are rather lisping than musical, though they sing pretty little s.n.a.t.c.hes in the woods; but many of their call-notes sound more like the squeaks and buzzings of insects and tree-toads than like the voices of birds, and it will take time and practice before you can distinguish them apart. I have chosen only half a dozen species to tell you of, from the half-hundred that rove about the United States. The first, and one that you are the most likely to see, is the Black-and-white Warbler."

THE BLACK-AND-WHITE WARBLER

"There are exceptions to everything," said the Doctor, as he pointed to an old willow tree on the edge of the river woods, where he had taken the children to look for Warblers. "And the exception among the shy Warblers of these woods is that sociable little black-and-white fellow over there, who is creeping and swinging about the branches as if he was own brother to the Brown Creeper himself. This Black-and-white Warbler hides his nest in an overturned stump, or on the ground, and you may try for days in vain, to find one. But at the same time he spends his time running merrily through the orchard trees, even whispering his husky 'weachy-weachy-twee-twee, tweet' to the old queen apple by the study window."

"Is that bird a Warbler?" asked Nat. "I thought he was some kind of a Nuthatch or a Woodp.e.c.k.e.r--he was with a whole lot of them up by the house last week."

"I used to think so too," said Rap; "but now I see a difference. The body and bill of the Nuthatch is stouter, and not such a pretty shape, and his bill almost turns up. This Warbler is thinner, with a slender bill that curves a little down, like the Brown Creeper's. Then too, he has smaller and finer stripes than any Woodp.e.c.k.e.r."

[Ill.u.s.tration: Black-And-White Warbler.]

"What guild does he belong to?" asked Dodo.

"To the Tree Trappers; most of the Warblers belong to this, while some have joined the Sky Sweepers, and a few the Ground Gleaners and Seed Sowers."

"Look!" said Nat. "He has spent a long time on one twig and he doesn't seem to have cleaned off all the insects yet; he must have pretty good eyes."

"Yes, and more than that," said the Doctor, "his eyes magnify much more than ours do, so that all objects appear far larger to a bird than they do to us, and they can see insects that we never notice."

"I wonder if that little Warbler thinks spiders are crabs and flies chickens," said Dodo, so soberly that all the others laughed heartily.

The Black-and-white Warbler

Length five inches.

Upper parts striped everywhere with black and white.

Under parts white in the middle, with many black stripes on the sides.

Has a weak and wheezy voice.

From its habit of scrambling about tree-trunks and branches, it may be mistaken for a real Creeper, or a Nuthatch, or even a little Woodp.e.c.k.e.r.

A Summer Citizen of the United States, east of the plains; in winter from Florida southward.

A Tree Trapper.

THE YELLOW WARBLER

(Or SUMMER YELLOWBIRD)

"I know this Warbler by sight already," said Dodo; "there is one in the low case in the wonder room--the pretty bird sitting on a fuzzy nest; it looks like a Canary."

"You may think that he looks like a Canary at a little distance, but not when you are near by," said the Doctor. "The Canary has a short, thick, cone-shaped bill suited to cracking seeds, while the Yellow Warbler has the slender bill necessary for prying into small cracks and crannies for insects. This Warbler also has light rusty streaks on his yellow breast. Do you remember having ever seen, a Canary with such markings?"

Nat and Dodo thought for a moment, and then said they never had.

"It really may not be like a Canary," said Rap, "and it hasn't much of a song, but it has so many cute little ways that it seems like one. I know a boy who always says it's a wild Canary, but it can't be that, I see. A pair of these Warblers have a nest in one of the elder bushes by our fence, and they wouldn't mind a bit if we went to look at them. Would it be too far for you to come, sir?" he inquired timidly of the Doctor, evidently proud of having something to show.

[Ill.u.s.tration: Yellow Warbler]

"We shall be glad to see the nest, my boy. How is it that you have so many birds about your house?"

"I think it's partly for the same reason that you have birds here--for we don't keep cats either--and it's partly because we have four big old mulberry trees."

"What have mulberry trees to do with birds?" asked Nat, without stopping to think.

"Everything," said the Doctor. "The mulberry is one of the most attractive fruits to our familiar birds, and at least twenty-five species feed upon it greedily.

"Whoever plants a mulberry tree in his garden sends a public invitation through Birdland for its people to come and live with him. The invitation is always accepted, and the birds appreciate the kindness so much that when they find mulberries they leave the cherries and strawberries in that garden in peace. This should teach us to plant wild fruits and berries for the birds, who prefer them to garden fruits."

As the children turned from the road into Rap's garden they saw that it held a great many birds. The bushes and trees were all untrimmed, and the old house with its s.h.i.+ngled sides and coast-backed roof was covered with a trumpet-creeper and some grape vines.

"What a lovely place for Hummingbirds!" cried Olive.

"And Martins," added the Doctor, pointing to a bird-box with ten or twelve divisions in it, that was fastened under the eaves.

"The Warbler's nest is here," said Rap, leading the way to a back fence and feeling very proud at the admiration his home was receiving.

The children tiptoed up and each took a peep into the cup-shaped nest.
