DUSKY; GRAY; AND SLATE…COLORED BIRDS
CHIMNEY SWIFT (Chaetura pelagica) Swift family
Called also: CHIMNEY SWALLOW; AMERICAN SWIFT
Length to 5。45 inches。 About an inch shorter than the English sparrow。 Long wings make its length appear greater。 Male and Female Deep sooty gray; throat of a trifle lighter gray。 Wings extend an inch and a half beyond the even tail; which has sharply pointed and very elastic quills; that serve as props。 Feet are muscular; and have exceedingly sharp claws。 Range Peculiar to North America east of the Rockies; and from Labrador to Panama。 Migrations April。 September or October。 Common summer resident。
The chimney swift is; properly speaking; not a swallow at all; though chimney swallow is its more popular name。 Rowing towards the roof of your house; as if it used first one wing; then the other; its flight; while swift and powerful; is stiff and mechanical; unlike the swallow's; and its entire aspect suggests a bat。 The nighthawk and whippoorwill are its relatives; and it resembles them not a little; especially in its nocturnal habits。
So much fault has been found with the misleading names of many birds; it is pleasant to record the fact that the name of the chimney swift is everything it ought to be。 No other birds can surpass and few can equal it in its powerful flight; sometimes covering a thousand miles in twenty…four hours; it is said; and never resting except in its roosting places (hollow trees or chimneys of dwellings); where it does not perch; but rather clings to the sides with its sharp claws; partly supported by its sharper tail。 Audubon tells of a certain plane tree in Kentucky where he counted over nine thousand of these swifts clinging to the hollow trunk。
Their nest; which is a loosely woven twig lattice; made of twigs of trees; which the birds snap off with their beaks and carry in their beaks; is glued with the bird's saliva or tree…gum into a solid structure; and firmly attached to the inside of chimneys; or hollow trees where there are no houses about。 Two broods in a season usually emerge from the pure white; elongated eggs。
What a twittering there is in the chimney that the swifts appropriate after the winter fires have died out! Instead of the hospitable column of smoke curling from the top; a cloud of sooty birds wheels and floats above it。 A sound as of distant thunder fills the chimney as a host of these birds; startled; perhaps; by some indoor noise; whirl their way upward。 Woe betide the happy colony if a sudden cold snap in early summer necessitates the starting of a fire on the hearth by the unsuspecting householder! The glue being melted by the fire; 〃down comes the cradle; babies and all〃 into the glowing embers。 A prolonged; heavy rain also causes their nests to loosen their hold and fall with the soot to the bottom。
Thrifty New England housekeepers claim that bedbugs; commonly found on bats; infest the bodies of swifts also; which is one reason why wire netting is stretched across the chimney tops before the birds arrive from the South。
KINGBIRD (Tyrannus tyrannus) Flycatcher family
Called also: TYRANT FLYCATCHER; BEE MARTIN; 'EASTERN KINGBIRD; AOU 1998'
Length 8 inches。 About two inches shorter than the robin。 Male Ashy black above; white; shaded with ash…color; beneath A concealed crest of orange…red on crown。 Tail black; Terminating with a white band conspicuous in flight。 Wing feathers edged with white。 Feet and bill black。 Female Similar to the male; but lacking the crown。 Range United States to the Rocky Mountains。 British provinces To Central and South America。 Migrations May。 September。 Common summer resident。
If the pugnacious propensity of the kingbird is the occasion of its royal name; he cannot be said to deserve it from any fine or noble qualities he possesses。 He is a born fighter from the very love of it; without provocation; rhyme; or reason。 One can but watch with a degree of admiration his bold sallies on the big; black crow or the marauding hawk; but when he bullies the small inoffensive birds in wanton attacks for sheer amusement; the charge is less entertaining。 Occasionally; when the little victim shows pluck and faces his assailant; the kingbird will literally turn tail and show the white feather。 His method of attack is always when a bird is in flight; then he swoops down from the telegraph pole or high point of vantage; and strikes on the head or back of the neck; darting back like a flash to the exact spot from which he started。 By these tactics he avoids a return blow and retreats from danger。 He never makes a fair hand…to…hand fight; or whatever is equivalent in bird warfare。 It is a satisfaction to record that he does not attempt to give battle to the catbird; but whenever in view makes a grand detour to give him a wide berth。
The kingbird feeds on beetles; canker…worms; and winged insects; with an occasional dessert of berries。 He is popularly supposed to prefer the honeybee as his favorite tidbit; but the weight of opinion is adverse to the charge of his depopulating the beehive; even though he owes his appellation bee martin to this tradition。 One or two ornithologists declare that he selects only the drones fur his diet; which would give him credit for marvellous sight in his rapid motion through the air。 The kingbird is preeminently a bird of the garden and orchard。 The nest is open; though deep; and not carefully concealed。 Eggs are nearly round; bluish white spotted with brown and lilac。 With truly royal exclusiveness; the tyrant favors no community of interest; but sits in regal state on a conspicuous throne; and takes his grand flights alone or with his queen; but never with a flock of his kind。
WOOD PEWEE (Contopus virens) Flycatcher family
Length 6。50 inches。 A trifle larger than the English sparrow。 Male Dusky brownish olive above; darkest on head; paler on throat; lighter still underneath; and with a yellowish tinge on the dusky gray under parts。 Dusky wings and tail; the wing coverts tipped with soiled white; forming two indistinct bars。 Whitish eye…ring。 Wings longer than tail。 Female Similar; but slightly more buff underneath。 Range Eastern North America; from Florida to northern British provinces。 Winters in Central America。 Migrations May。 October。 Common summer resident
The wood pewee; like the olive…sided flycatcher; has wings decidedly longer than its tail; and it is by no means a simple matter for the novice to tell these birds apart or separate them distinctly in the mind from the other members of a family whose coloring and habits are most confusingly similar。 This dusky haunter of tall shady trees has not yet learned to be sociable like the phoebe; but while it may not be so much in evidence close to our homes; it is doubtless just as common。 The orchard is as near the house as it often cares to come。 An old orchard; where modern insecticides are unknown and neglect allows insects to riot among the decayed bark and fallen fruit; is a happy hunting ground enough; but the bird's real preferences are decidedly for high tree…tops in the woods; where no sunshine touches the feathers on his dusky coat。 It is one of the few shade…loving birds。 In deep solitudes; where it surely retreats by nesting time; however neighborly it may be during the migrations; its pensive; pathetic notes; long drawn out; seem like the expression of some hidden sorrow。 Pe…a…wee; pe…a…wee; pewee…ah…peer is the burden of its plaintive song; a sound as depressing as it is familiar in every walk through the woods; and the bird's most prominent characteristic。
To see the bird dashing about in his aerial chase for insects; no one would accuse him of melancholia。 He keeps an eye on the 〃main chance;〃 whatever his preying grief may be; and never allows it to affect his appetite。 Returning to his perch after a successful sally in pursuit of the passing fly; he repeats his 〃sweetly solemn thought〃 over and over again all day long and every day throughout the summer。
The wood pewees show that devotion to each other and to their home; characteristic of their family。 Both lovers work on the construction of the flat nest that is saddled on some mossy or lichen…covered limb; and so cleverly do they cover the rounded edge with bits of bark and lichen that sharp eyes only can detect where the cradle lies。 Creamy…white eggs; whose larger end is wreathed with brown and lilac spots; are guarded with fierce solicitude。
Trowbridge has celebrated this bird in a beautiful poem。
