plements his fish diet with various kinds of the larger insects； shrimps； and fresh…water mollusks。
Flying well over the tree…tops or along the waterways。 the kingfisher makes the woodland echo with his noisy rattle； that breaks the stillness like a watchman's at midnight。 It is； perhaps； the most familiar sound heard along the banks of the inland rivers。 No love or cradle song does he know。 Instead of softening and growing sweet； as the voices of most birds do in the nesting season； the endearments uttered by a pair of mated kingfishers are the most strident； rattly shrieks ever heard by lovers it sounds as if they were perpetually quarrelling； yet they are really particularly devoted。
The nest of these birds； like the bank swallow's； is excavated in the face of a high bank； preferably one that rises from a stream； and at about six feet from the entrance of the tunnel six or eight clear； shining white eggs are placed on a curious nest。 All the fish bones and scales that； being indigestible； are disgorged in pellets by the parents； are carefully carried to the end of the tunnel to form a prickly cradle for the unhappy fledglings。 Very rarely a nest is made in the hollow trunk of a tree； but wherever the home is； the kingfishers become strongly attached to it； returning again and again to the spot that has cost them so much labor to excavate。 Some observers have accused them of appropriating the holes of the water…rats。
In ancient times of myths and fables； kingfishers or halcyons were said to build a floating nest on the sea； and to possess some mysterious power that calmed the troubled waves while the eggs were hatching and the young birds were being reared； hence the term 〃halcyon days；〃 meaning days of fair weather。
BLUE JAY （Cyanocitta cristata） Crow and Jay family
Length 11 to 12 inches。 A little larger than the robin。
Male and Female Blue above。 Black band around the neck； joining some black feathers on the back。 Under parts dusky white。 Wing coverts and tail bright blue； striped transversely with black。 Tail much rounded。 Many feathers edged and tipped with white。 Head finely crested； bill； tongue； and legs black。 Range Eastern coast of North America to the plains； and from northern Canada to Florida and eastern Texas。 Migrations Permanent resident。 Although seen in flocks moving southward or northward； they are merely seeking happier hunting grounds； not migrating。
No bird of finer color or presence sojourns with us the year round than the blue jay。 In a peculiar sense his is a case o。 〃beauty covering a multitude of sins。〃 Among close students of bird traits； we find none so poor as to do him reverence。 Dishonest； cruel； inquisitive； murderous； voracious； villainous； are some of the epithets applied to this bird of exquisite plumage。 Emerson； however； has said in his defence he does 〃more good than harm；〃 alluding； no doubt； to his habit of burying nuts and hard seeds in the ground； so that many a waste place is clothed with trees and shrubs； thanks to his propensity and industry。
He is mischievous as a small boy； destructive as a monkey； deft at hiding as a squirrel。 He is unsociable and unamiable； disliking the society of other birds。 His harsh screams； shrieks； and most aggressive and unmusical calls seem often intended maliciously to drown the songs of the sweet…voiced singers。
From April to September； the breeding and moulting season； the blue jays are almost silent； only sallying forth from the woods to pillage and devour the young and eggs of their more peaceful neighbors。 In a bulky nest； usually placed in a tree…crotch high above our heads； from four to six eggs； olive…gray with brown spots； are laid and most carefully tended。
Notwithstanding the unlovely characteristics of the blue jay； we could ill spare the flash of color； like a bit of blue sky dropped from above； which is so rare a tint even in our land； that we number not more than three or four true blue birds； and in England； it is said； there is none。
BLUE GROSBEAK （Guiraca carulea） Finch family
Length 7 inches。 About an inch larger than the English sparrow。 Male Deep blue； dark； and almost black on the back； wings and tail black； slightly edged with blue； and the former marked with bright chestnut。 Cheeks and chin black。 Bill heavy and bluish。 Female Grayish brown above； sometimes with bluish tinge on head； lower back； and shoulders。 Wings dark olive…brown； with faint buff markings； tail same shade as wings； but witb bluish gray markings。 Underneath brownish cream…color； the breast feathers often blue at the base。 Range United States； from southern New England westward to the Rocky Mountains and southward into Mexico and beyon d。M ost common in the Southwest。 Rare along the Atlantic seaboard。 Migrations May。 September。 Summer resident。
This beautiful but rather shy and solitary bird occasionally wanders eastward to rival the bluebird and the indigo bunting in their rare and lovely coloring； and eclipse them both in song。 Audubon； we remember； found the nest in New Jersey。 Pennsylvania is still favored with one now and then； but it is in the Southwest only that the blue grosbeak is as common as the evening grosbeak is in the Northwest。 Since rice is its favorite food； it naturally abounds where that cereal grows。 Seeds and kernels of the hardest kinds； that its heavy； strong beak is well adapted to crack； constitute its diet when it strays beyond the rice…fields。
Possibly the heavy bills of all the grosbeaks make them look stupid whether they are or not a characteristic that the blue grosbeak's habit of sitting motionless with a vacant stare many minutes at a time unfortunately emphasizes。
When seen in the roadside thickets or tall weeds； such as the field sparrow chooses to frequent； it shows little fear of man unless actually approached and threatened； but whether this fearlessness comes from actual confidence or stupidity is by no means certain。 Whatever the motive of its inactivity； it accomplishes an end to be desired by the cleverest bird； its presence is almost never suspected by the passer…by； and its grassy nest on a tree…branch； containing three or four pale bluish…white eggs； is never betrayed by look or sign to the marauding small boy。
BARN SWALLOW （Chelidon erythrogaster） Swallow family
Length 6。5 to 7 inches。 A trifle larger than the English sparrow。 Apparently considerably larger； because of its wide wingspread。 Male Glistening steel…blue shading to black above。 Chin； breast； and underneath bright chestnut…brown and brilliant buff that glistens in the sunlight。 A partial collar of steel…blue。 Tail very deeply forked and slender。 Female Smaller and paler； with shorter outer tail feathers； making the fork less prominent。 Range Throughout North America。 Winters in tropics of both Americas。 Migrations April。 September。 Summer resident。
Any one who attempts to describe the coloring of a bird's plumage knows how inadequate words are to convey a just idea of the delicacy； richness； and brilliancy of the living tints。 But； happily； the beautiful barn swallow is too familiar to need description。 Wheeling about our barns and houses； skimming over the fields； its bright sides flashing in the sunlight； playing 〃cross tag〃 with its friends at evening； when the insects； too； are on the wing； gyrating； darting； and gliding through the air； it is no more possible to adequately describe the exquisite grace of a swallow's flight than the glistening buff of its breast。
This is a typical bird of the air； as an oriole is of the trees and a sparrow of the ground。 Though the swallow may often be seen perching on a telegraph wire； suddenly it darts off as if it had received a shock of electricity； and we see the bird in its true element。
While this swallow is peculiarly American； it is often confounded with its European cousin Hirundo rustica in noted ornithologies。
Up in the rafters of the barn； or in the arch of an old bridge that spans a stream； these swallows build their bracket…like nests of clay or mud pellets intermixed with straw。 Here the noisy little broods pick their way out of the white eggs curiously spotted with brown and lilac that were all too familiar in the marauding days of our childhood。
CLIFF SWALLOW （Petrochelidon lunifrons） Swallow family
Called also： EAVE SWALLOW； CRESCENT SWALLOW； ROCKY MOUNTAIN SWALLOW
Length 6 inches。 A trifle smaller than the English sparrow。 Apparently considerably larger because of its wide wingspread。 Male and Female Steel…blue above； shading to blue…black on crown of head and on wings and tail。 A brownish…gray ring around the neck。 Beneath dusty white； with rufous tint。 Crescent…like frontlet。 Chin； throat； sides of head； and tail coverts rufous。 Range North and South America。 Winters in the tropics。 Migrations Early April。 Late September。 Summer resident。
Not quite so brilliantly colored as the barn swallow； nor with tail so deeply forked； and consequently without so much grace in flying； and with a squeak rather than the really musical twitter of the gayer bird； the cliff swallow may be positively identified by the rufous feathers of its tail coverts； but more
