MYRTLE WARBLER （Dendroica coronata） Wood Warbler family
Called also： YELLOW…RUMPED WARBLER ＇AOU 1998＇； MYRTLE BIRD； YELLOW…CROWNED WARBLER
Length 5 to 5。5 inches。 About an inch smaller than the English sparrow。 Male In summer plumage： A yellow patch on top of head； lower back； and either side of the breast。 Upper parts bluish slate； streaked with black。 Upper breast black； throat white； all other under parts whitish； streaked with black。 Two white wing bars； and tail quills have white spots near the tip。 In winter： Upper parts olive…brown； streaked with black； the yellow spot on lower back the only yellow mark remaining。 Wing…bars grayish。 Female Resembles male in winter plumage。 Range Eastern North America。 Occasional on Pacific slope。 Summers from Minnesota and northern New England northward to Fur Countries。 Winters from Middle States south ward into Central America； a few often remaining at the northern United States all the winter。 Migrations April。 October。 November。 Also； but more rarely； a winter resident。
The first of the warblers to arrive in the spring and the last to leave us in the autumn； some even remaining throughout the northern winter； the myrtle warbler； next to the summer yellowbird； is the most familiar of its multitudinous kin。 Though we become acquainted with it chiefly in the migrations； it impresses us by its numbers rather than by any gorgeousness of attire。 The four yellow spots on crown； lower back； and sides are its distinguishing marks； and in the autumn these marks have dwindled to only one； that on the lower back or rump。 The great difficulty experienced in identifying any warbler is in its restless habit of flitting about。
For a few days in early May we are forcibly reminded of the Florida peninsula； which fairly teems with these birds； they become almost superabundant； a distraction during the precious days when the rarer species are quietly slipping by； not to return again for a year； perhaps longer； for some warblers are notoriously irregular in their routes north and south； and never return by the way they travelled in the spring。
But if we look sharply into every group of myrtle warblers； we are quite likely to discover some of their dainty； fragile cousins that gladly seek the escort of birds so fearless as they。 By the last of May all the warblers are gone from the neighborhood except the constant little summer yellowbird and redstart。
In autumn； when the myrtle warblers return after a busy enough summer passed in Canadian nurseries； they chiefly haunt those regions where juniper and bay…berries abound。 These latter （Myrica cerifera）； or the myrtle wax…berries； as they are sometimes called； and which are the bird's favorite food； have given it their name。 Wherever the supply of these berries is sufficient to last through the winter； there it may be found foraging in the scrubby bushes。 Sometimes driven by cold and hunger from the fields； this hardiest member of a family that properly belongs to the tropics； seeks shelter and food close to the outbuildings on the farm。
PARULA WARBLER （Compsothlypis americana） Wood Warbler family
Called also： BLUE YELLOW…BACKED WARBLER； ＇NORTHERN PARULA； AOU 1998＇ Length 4。5 to 4。75 inches。 About an inch and a half shorter than the English sparrow。 Male and Female Slate…colored above； with a greenish…yellow or bronze patch in the middle of the back。 Chin； throat； and breast yellow。 A black； bluish； or rufous band across the breast； usually lacking in female。 Underneath white； sometimes marked with rufous on sides； but these markings are variable。 Wings have two white patches； outer tail feathers have white patch near the end。 Range Eastern North America。 Winters from Florida southward。 Migrations April。 October。 Summer resident。
Through an open window of an apartment in the very heart of New York City； a parula warbler flew this spring of 1897； surely the daintiest； most exquisitely beautiful bird visitor that ever voluntarily lodged between two brick walls。
A number of such airy； tiny beauties flitting about among the blossoms of the shrubbery on a bright May morning and swaying on the slenderest branches with their inimitable grace； is a sight that the memory should retain into old age。 They seem the very embodiment of life； joy； beauty； grace； of everything lovely that birds by any possibility could be。 Apparently they are wafted about the garden； they fly with no more effort than a dainty lifting of the wings； as if to catch the breeze； that seems to lift them as it might a bunch of thistledown。 They go through a great variety of charming posturings as they hunt for their food upon the blossoms and tender fresh twigs； now creeping like a nuthatch along the bark and peering into the crevices； now gracefully swaying and balancing like a goldfinch upon a slender； pendent stem。 One little sprite pauses in its hunt for the insects to raise its pretty head and trill a short and wiry song。
But the parula warbler does not remain long about the gardens and orchards； though it will not forsake us altogether for the Canadian forests； where most of its relatives pass the summer。 It retreats only to the woods near the water； if may be； or to just as close a counterpart of a swampy southern woods； where the Spanish or Usnea 〃moss〃 drapes itself over the cypresses； as it can find here at the north。 Its rarely ＇found；＇ beautiful nest； that hangs suspended from a slender branch very much like the Baltimore oriole's； is so woven and festooned with this moss that its concealment is perfect。
BLACK…THROATED BLUE WARBLER （Dendroica caerulescens） Wood Warbler family
Length 5。30 inches。 About an inch shorter than the English sparrow。 Male Slate…color； not blue above； lightest on forehead and darkest on lower back。 Wings and tail edged with bluish。 Cheeks； chin； throat； upper breast； and sides black。 Breast and underneath white。 White spots on wings； and a little white on tail。 Female Olive…green above； underneath soiled yellow。 Wing…spots inconspicuous。 Tail generally has a faint bluish tinge。 Range Eastern North America； from Labrador to tropics； where It winters。 Migrations May。 September。 Usually a migrant only in the United States。
Whoever looks for this beautifully marked warbler among the bluebirds； will wish that the man who named him had possessed a truer eye for color。 But if the name so illy fits the bright slate…colored male； how grieved must be his little olive…and…yellow mate to answer to the name of black…throated blue warbler when she has neither a black throat nor a blue feather！ It is not easy to distinguish her as she flits about the twigs and leaves of the garden in May or early autumn； except as she is seen in company with her husband； whose name she has taken with him for better or for worse。 The white spot on the wings should always be looked for to positively identify this bird。
Before flying up to a twig to peck off the insects； the birds have a pretty vireo trick of cocking their heads on one side to investigate the quantity hidden underneath the leaves。 They seem less nervous and more deliberate than many of their restless family。
Most warblers go over the Canada border to nest； but there are many records of the nests of this species in the Alleghanies as far south as Georgia； in the Catskills； in Connecticut； northern Minnesota and Michigan。 Laurel thickets and moist undergrowth of woods in the United States； and more commonly pine woods in Canada； are the favorite nesting haunts。 A sharp zip； zip； like some midsummer insect's noise； is the bird's call…note； but its love…song； zee； zee； zee； or twee； twea； twea…e…e； as one authority writes it； is only rarely heard in the migrations。 It is a languid； drawling little strain； with an upward slide that is easily drowned in the full bird chorus of May。

With the first soft； plaintive warble of the bluebirds early in March； the sugar camps； waiting for their signal； take on a bustling activity； the farmer looks to his plough； orders are hurried off to the seedsmen； a fever to be out of doors seizes one： spring is here。 S
