TUBDID^ — REGULINJE : KINGLETS. 259 



tail-coverts rather lighter, and mixed with bright chestnut-red. Wings like the back, with 

 slightly paler edgings of the feathers. Middle tail-feathers like back, or rather darker, the rest 

 blackish, with the basal half t)r more of their length briglit chestnut-red, or orange-brown. 

 Lores dusky ; a whitish superciliary line. Chin, throat, and forebreast rich ultramarine blue, 

 enclosing a bright chestnut throat-patch ; the blue bordered behind by black, this again by 

 chestnut mixed with white. Rest of under parts white, washed on the sides, lining of wings 

 and under tail-coverts with pale fulvous. Bill and feet black. 9 and young similar, the 

 throat-markings imperfect. Length 5.75-6.00; wing 3.00; tail 2.25-2.50; bill 0.50; tarsus 

 1.00 ; middle toe and claw 0.75. Alaska; a beautiful and interesting bird, widely distributed 

 in the Old World. 



5. Subfamily RECULIN/E: Kinglets and Wood-Wrens. 



The two genera to be here noticed are most readily distinguished by the simple colors of 

 Plujlloscopus, contrasted with the elegant colored crest of Eegulus ; both genera include very • 

 (liniinutive birds not over five inches long. 

 9. PHYLLO'SCOPUS. (Gr. (f)vXKov, plmlloyi, a leaf; o-kottos, skopos, a watchman; as these 

 birds peer about in the foliage.) Wood-Wrens. Bill shorter than head, slender, straight, 

 depressed at base, compressed and notched at tip ; nostrils exposed, though reached by the 

 fi*ontal feathers. Tarsus longer than middle toe and claw, booted or sometimes indistinctly 

 scutellate ; wings pointed, longer than tail ; point formed by 3d and 4th quills ; 5th much 

 shorter, and 6th shorter still, 2d between 5th and 6th; spurious 1st primary very short, exposed 

 less than 0.50. Tail about even. Size diminutive and coloration simple. Includes numerous 

 (about 25) Old World species, one of them occurring in Alaska. 



32. P. borea'lis. (Lat. fcoreafos, northern ; feoreas, the north-wind.) Kennicott's Warbler. 

 Above, olive-green, clear, continuous, and nearly uniform, but rather brighter on the romp ; 

 quills and tail-feathers fuscous, edged externally with yellowish-green ; a long yellowish super- 

 ciliary stripe; under parts yellowish-white, the lining of wings and the flanks yellow; wings 

 <-rossed with two yellowish bars, that across ends of greater coverts conspicuous, the other 

 indistinct ; bill dark brown, pale below ; feet and eyes brown. Length 4.75 ; extent 6.00 ; 

 "wing 2.25-2.50; tail 1.75-2.00; tarsus 0.70; middle toe and claw 0.55. Europe, Asia, and, 

 in America, Alaska. 



10. REG'ULUS. (Lat. rer/wZws, diminutive of rex, a king ; kinglet.) Kinglets. Tarsus booted, 

 very slender, longer than the middle toe and claw. Lateral toes nearly equal to each other. 

 First quill of the wing spurious, its exposed portion less than half as long as the second. 

 Wings pointed, longer than the tail, which is emarginate, with acuminate feathers. Bill 

 shorter than the head, straight, slender, and typically Sylviine, not hooked at the end, well 

 bristled at rictus, with the nostrils overshadowed by tiny feathers. Coloration olivaceous, 

 paler or whitish below, with red, black, or yellow, or all three of these colors, on the head of 

 the adult. There are about ten species, of Europe, Asia, and America. They are elegant and 

 dainty little creatures, among the very smallest of our birds exce^Jting the Hummers. They 

 inhabit woodland, are very agile and sprightly, insectivorous, migratory, and highly musical. 



33. K. calen'dula. (Lat. calendula, a glowing little thing.) Ruby-crowned Kinglet. $ 9 , 

 adult : Upper parts greenish-olive, becoming more yellowish on the rump ; wings and tail 

 dusky, strongly edged with yellowish ; whole under parts dull yellowish-white, or yellowish - 

 or greenish-gray (very variable in tone) ; wings crossed with two whitish bars, and inner sec- 

 ondaries edged with the same. Edges of eyelids, lores, and extreme forehead, hoary whitish. 

 A rich scarlet ]?atch, partially concealed, on tlie crown. This beautiful ornament is a])parently 

 not gained until the second year, and there is a question whether it is ever present in the 

 female. Bill and feet black. Length 4.10-1.50 ; extent 6.66-7.33 ; wing 2.00-2.33 ; tail 

 1.75 ; bill 0.25 ; tarsus 0.75. Young for the first year (and 9 ?) : Quite like the adult, but
