SYLVICULID.E — THE WARBLERS. 243 



described by Audubon. The egg i.s pure crystal-white, oblong and pointed, 

 and marked witli i)urple and brown. 



Mr. liidgway informs me that in Souihrvn Illiunis, at least in the valley 

 of the Lower Wabash, tlie Yellow-throated Warbler may be said to be at least 

 a regular, though not conunon, summer sojourner. Though it inhabits chiefly 

 the swanipv portions of the bottom-lands, it makes frei[uent visits to the or- 

 cliards and door-yards, less often, liowever, in tiie breeding than m the mi- 

 grating season. In its manners it is almost as much of a Creeper as the 

 Mniotilta mri", being freijuently seen creeping not (uily along the branches 

 of trees, btit over tlie eaves and cornices of buililings, with all tiie facility 

 of a Xuthateii. 



Eggs supposed to be of tliis species, taken near Wilmington, N. C, by 

 Mr. Norwood Giles (16,199, Smith. Cull), iiave a ground-color of dull ashy- 

 white, with a livid tinge. They are thickly speckled, chiefly around the 

 larger end, with irregular markings of rufous, and fainter ones of lilac in- 

 terspersed with a N'ery few mintxte specks of black. They are broadly ovate 

 in form, and measure .~0 by .5.3 of an incli.

 iiicludinu' ear-coverts and sides of neck, a.sh-gray ; small ouneate streaks over the crown, 

 coalesced laterally into a broad stripe on each side, with larger cuneate streaks on the inter- 

 scapular region, and inconspicuous linear streaks on upper tail-coverts, black. Two con- 

 spicuous white bands across the wing, formed by the tips of middle and secondary coverts ; 

 secondaries pas.sing externally into light ash. Lateral tail-feather entirely white, except 

 about the basal third of the inner web (the dusky running some distance towai'd the end 

 along the edge), and a broad streak covering most of the terminal fourth of the outer web, 

 wliich are clear dusky ; the next feather has the outer web exactly the same, but almost 

 the basal half of the inner is dusky ; on the next the white is confined to an oblong spot (not 

 touching the inner edge) on about the terminal third, while the outer web is only edged 

 with white ; the rest have no white at all. A .superciliary stripe extending about .20 of 

 an inch behind the eye (that portion behind the eye white), the lower eyelid, maxillas, 

 chin, throat, and jugulum pure gamboge-yellow. Rest of lower parts, including lining of 

 wing, pure white ; the sides conspicuousl}' streaked with black ; lores, and a few obsolete 

 streaks along the junction of the ash and yellow, dusky. Wing, 2.60 ; tail, 2.20 ; bill (from 

 nostril), .30 ; tarsu.s, .60. Adult female (40:68.5, May 24). Similar to the male, but colors 

 duller, and markings less sharply defined. Wing, 2.4,5 ; tail, 2.00. Young (36,992, August 

 llj. Above brownish-gray without strealcs. Beneath ochraceous-white, obsoletely streaked 

 along the sides. Yellow superciliary stripe not well defined, and only a tinge of yellow 

 on the jugulum, the throat being grayish-white. Wings and tail nearly as in the adult. 

 The young in autunnial plumage is similar, but the yellow occupies its usual area ; it is, 

 however, much duller, as well as lighter, than in the adult.
