fall through or roll out of the rickety lattice； their tender little naked bodies must suffer from many bruises。 We are almost inclined to blame the inconsiderate mother for allowing her offspring to enter the world unclothed obviously not her fault； though she is capable of just such negligence。 Fortunate are the baby doves when their lazy mother scatters her makeshift nest on top of one that a robin has deserted； as she frequently does。 It is almost excusable to take her young birds and rear them in captivity； where they invariably thrive； mate； and live happily； unless death comes to one； when the other often refuses food and grieves its life away。
In the wild state； when the nesting season approaches； both birds make curious acrobatic flights above the tree…tops； then； after a short sail in midair； they return to their perch。 This appears to be their only giddiness and frivolity； unless a dust…bath in the country road might be considered a dissipation。
In the autumn a few pairs of doves show slight gregarious tendencies； feeding amiably together in the grain fields and retiring to the same roost at sundown。
BLUE…GRAY GNATCATCHER （Polioptila coerulea） Gnatcatcher family
Called also： SYLVAN FLYCATCHER
Length 4。5 inches。 About two inches smaller than the English sparrow。 Male Grayish blue above； dull grayish white below。 Grayish tips on wings。 Tail with white outer quills changing gradually through black and white to all black on centre quills。 Narrow black band over the forehead and eyes。 Resembles in manner and form a miniature catbird。 Female More grayish and less blue； and without the black on head。 Range United States to Canadian border on the north； the Rockies on the west； and the Atlantic States； from Maine to Florida most common in the Middle States。 A rare bird north of New Jersey。 Winters in Mexico and beyond。 Migrations May。 September。 Summer resident。
In thick woodlands； where a stream that lazily creeps through the mossy； oozy ground attracts myriads of insects to its humid neighborhood； this tiny hunter loves to hide in the denser foliage of the upper branches。 He has the habit of nervously flitting about from twig to twig of his relatives； the kinglets； but unhappily he lacks their social； friendly instincts； and therefore is rarely seen。 Formerly classed among the warblers； then among the flycatchers； while still as much a lover of flies； gnats； and mosquitoes as ever； his vocal powers have now won for him recognition among the singing birds。 Some one has likened his voice to the squeak of a mouse； and Nuttall says it is 〃scarcely louder；〃 which is all too true； for at a little distance it is quite inaudible。 But in addition to the mouse…like call…note； the tiny bird has a rather feeble but exquisitely finished song； so faint it seems almost as it the bird were singing in its sleep。
If by accident you enter the neighborhood of its nest； you soon find out that this timid； soft…voiced little creature can be roused to rashness and make its presence disagreeable to ears and eyes alike as it angrily darts about your unoffending head； pecking at your face and uttering its shrill squeak close to your very ear…drums。 All this excitement is in defence of a dainty； lichen…covered nest； whose presence you may not have even suspected before； and of four or five bluish…white； speckled eggs well beyond reach in the tree…tops。
During the migrations the bird seems not unwilling to show its delicate； trim little body； that has often been likened to a diminutive mocking…bird's； very near the homes of men。 Its graceful postures； its song and constant motion； are sure to attract attention。 In Central Park； New York City； the bird is not unknown。

BROWN； OLIVE OR GRAYISH BROWN； AND BROWN AND GRAY SPARROWY BIRDS
HOUSE WREN （Troglodytes aedon） Wren family
Length 4。5 to 5 inches。 Actually about one…fourth smaller than the English sparrow； apparently only half as large because of its erect tail。 Male and Female Upper parts cinnamon…brown。 Deepest shade on head and neck； lightest above tail； which is more rufous。 Back has obscure； dusky bars； wings and tail are finely barred。 Underneath whitish； with grayish…brown wash and faint bands Most prominent on sides。 Range North America； from Manitoba to the Gulf。 Most common in the United States； from the Mississippi eastward。 Winters south of the Carolinas。 Migrations April October。 Common summer resident。
Early some morning in April there will go off under your window that most delightful of all alarm…clocks the tiny； friendly house wren； just returned from a long visit south。 Like some little mountain spring that； having been imprisoned by winter ice； now bubbles up in the spring sunshine； and goes rippling along over the pebbles； tumbling over itself in merry cascades； so this little wren's song bubbles； ripples； cascades in a miniature torrent of ecstasy。
Year after year these birds return to the same nesting places： a box set up against the house； a crevice in the barn； a niche under the eaves； but once home； always home to them。 The nest is kept scrupulously clean； the house…cleaning； like the house…building and renovating； being accompanied by the cheeriest of songs； that makes the bird fairly tremble by its intensity。 But however angelic the voice of the house wren； its temper can put to flight even the English sparrow。 Need description go further。
Six to eight minutely speckled； flesh…colored eggs suffice to keep the nervous； irritable parents in a state bordering on frenzy whenever another bird comes near their habitation。 With tail erect and head alert； the father mounts on guard； singing a perfect ecstasy of love to his silent little mate； that sits upon the nest if no danger threatens； but both rush with passionate malice upon the first intruder； for it must be admitted that Jenny wren is a sad shrew。
While the little family is being reared； or； indeed； at any time； no one is wise enough to estimate the millions of tiny insects from the garden that find their way into the tireless bills of these wrens。
It is often said that the house wren remains at the north all the year； which； though not a fact； is easily accounted for by the coming of the winter wrens just as the others migrate in the autumn； and by their return to Canada when Jenny wren makes up her feather…bed under the eaves in the spring。
CAROLINA WREN （Thryothorus ludovicianus） Wren family
Called also： MOCKING WREN
Length 6 inches。 Just a trifle smaller than the English sparrow Male and Female Chestnut…brown above。 A whitish streak； beginning at base of bill； passes through the eye to the nape of the neck。 Throat whitish。 Under parts light b
