d the black…and…white lines over its ruby eye； that； in addition to the song； are its marked characteristics。
Whether she is excessively stupid or excessively kind； the mother…vireo has certainly won for herself no end of ridicule by allowing the cowbird to deposit a stray egg in the exquisitely made； pensile nest； where her own tiny white eggs are lying and though the young cowbird crowd and worry her little fledglings and eat their dinner as fast as she can bring it in； no displeasure or grudging is shown towards the dusky intruder that is sure to upset the rightful heirs out of the nest before they are able to fly。
In the heat of a midsummer noon； when nearly every other bird's voice is hushed； and only the locust seems to rejoice in the fierce sunshine； the little red…eyed vireo goes persistently about its business of gathering insects from the leaves； not flitting nervously about like a warbler； or taking its food on the wing like a flycatcher； but patiently and industriously dining where it can； and singing as it goes。
When a worm is caught it is first shaken against a branch to kill it before it is swallowed。 Vireos haunt shrubbery and trees with heavy foliage； all their hunting； singing； resting； and home…building being done among the leaves never on the ground。
WHITE…EYED VIREO （Vireo noveboracensis） Vireo or Greenlet family
Male 5 to 5。3 inches。 An inch shorter than the English sparrow。 Male and Female Upper parts bright olive…green； washed with grayish。 Throat and underneath white； the breast and sides greenish yellow； wings have two distinct bars of yellowish white。 Yellow line from beak to and around the eye； which has a white iris。 Feathers of wings and tail brownish and edged with yellow。 Range United States to the Rockies； and to the Gulf regions And beyond in winter。 Migrations May。 September。 Summer resident。
〃Pertest of songsters；〃 the white…eyed vireo makes whatever neighborhood it enters lively at once。 Taking up a residence in the tangled shrubbery or thickety undergrowth； it immediately begins to scold like a crotchety old wren。 It becomes irritated over the merest trifles a passing bumblebee； a visit from another bird to its tangle； an unsuccessful peck at a gnat anything seems calculated to rouse its wrath and set every feather on its little body a…trembling； while it sharply snaps out what might perhaps be freely constructed into 〃cuss…words。〃
And yet the inscrutable mystery is that this virago meekly permits the lazy cowbird to deposit an egg in its nest； and will patiently sit upon it； though it is as large as three of her own tiny eggs； and when the little interloper comes out from his shell the mother…bird will continue to give it the most devoted care long after it has shoved her poor little starved babies out of the nest to meet an untimely death in the smilax thicket below。
An unusual variety of expression distinguishes this bird's voice from the songs of the other vireos； which are apt to be monotonous； as they are incessant。 If you are so fortunate to approach the white…eyed vireo before he suspects your presence； you may hear him amusing himself by jumbling together snatches of the songs of the other birds in a sort of potpourri； or perhaps he will be scolding or arguing with an imaginary foe； then dropping his voice and talking confidentially to himself。 Suddenly he bursts into a charming； simple little song； as if the introspection had given him reason for real joy。 All these vocal accomplishments suggest the chat at once； but the minute your intrusion is discovered the sharp scolding； that is fairly screamed at you from an enraged little throat； leaves no possible shadow of a doubt as to the bird you have disturbed。 It has the most emphatic call and song to be heard in the woods； it snaps its words off very short。 〃Chick…a…rer chick〃 is its usual call…note； jerked out with great spitefulness。
Wilson thus describes the jealously guarded nest： 〃This bird builds a very neat little nest； often in the figure of an inverted cone； it is suspended by the upper end of the two sides； on the circular bend of a prickly vine； a species of smilax； that generally grows in low thickets。 Outwardly it is constructed of various light materials； bits of rotten wood； fibres of dry stalks； of weeds； pieces of paper （commonly newspapers； an article almost always found about its nest； so that some of my friends have given it the name of the politician）； all these materials are interwoven with the silk of the caterpillars； and the inside is lined with fine； dry grass and hair。〃
WARBLING VIREO （Vireo gilvus） Vireo or Greenlet family
Length 5。5 to 6 inches。 A little smaller than the English sparrow。 Male and Female Ashy olive…green above； with head and neck ash…colored。 Dusky line over the eye。 Underneath whitish； faintly washed with dull yellow； deepest on sides； no bars on wings。 Range North America； from Hudson Bay to Mexico。 Migrations May。 Late September or early October。 Summer resident。
This musical little bird shows a curious preference for rows of trees in the village street or by the roadside； where he can be sure of an audience to listen to his rich； continuous warble。 There is a mellowness about his voice； which rises loud； but not altogether cheerfully； above the bird chorus； as if he were a gifted but slightly disgruntled contralto。 Too inconspicuously dressed； and usually too high in the tree…top to be identified without opera…glasses； we may easily mistake him by his voice for one of the warbler family； which is very closely allied to the vireos。 Indeed； this warbling vireo seems to be the connecting link between them。
Morning and afternoon； but almost never in the evening； we may hear him rippling out song after song as he feeds on insects and berries about the garden。 But this familiarity lasts only until nesting time； for off he goes with his little mate to some unfrequented lane near a wood until their family is reared； when； with a perceptibly happier strain in his voice； he once more haunts our garden and row of elms before taking the southern journey。
OVENBIRD （Seiurus aurocapillus） Wood Warbler family

Early in May you may have the good fortune to see this little bird of the woods strutting in and out of the garden shrubbery with a certain mock dignity； like a child wearing its father's boots。 Few birds can walk without appearing more or less ridiculous； and however gracefully and prettily it steps； this amusing little wagtail is no exception。 When seen at all which is not often； for it is shy it is usually on the ground； not far from the shrubbery or a woodland thicket； under which it will quickly dodge out of sight at the merest
