296 BlEDS OF XORTH CAROLINA 



Although early April is the usual time for nest building to begin, we have found 

 nests as early as March 20, in 1890, and as late as May 24 in the same year. Mr. 

 Adickes, Assistant Curator of the State Museum, has taken one nest in June. About 

 two weeks time is sufficient to build the nest and deposit a full set of eggs, unless 

 interrupted by unseasonable weather. If the nest is taken, the birds will at once 

 build another, and this will have its full complement of eggs in two weeks from 

 the time the first was destroyed. This action will be repeated several times if the 

 birds are continually disturbed. The nests are comparatively easy to find by watch- 

 ing the birds while the building is in progress. 



Although the Pine Warbler is essentially a bird of the pine woods, yet in the fall 

 it is often found in mixed woods in large numbers, and in the winter, when food 

 is scarce, it sometimes collects about dwellings and farmyards and even in open 

 fields.

 mainly in British America, and wintering in the West Indies. 



Range in North Carolina. So far, only recorded from the mountains and central part of the 

 State as a spring migrant. 



FIG. 239. PALM WARBLER. 



A single female taken at Blantyre May 6, 1908, seems referable here, as also 

 does one taken at Raleigh May 1, 1893. Cooke states that migrants recorded by 

 Cairns as late as May 13, in Buncombe County, probably belong here, as this is 

 later in the season than the next form is supposed to appear. 



300. Dendroica palmarum hypochrysea (Ridgw.). YELLOW PALM WAR- 

 BLER. 



Description: Ads. Crown chestnut; back brownish olive-green; rump olive-green; no white 

 wing-bars; secondaries sometimes tinged with chestnut; tail edged with olive-green, the outer 

 feathers with white spots on their inner vanes near the tips; line over the eye and eye-ring yellow; 

 underparts entirely bright yellow; sides of the throat, the breast, and sides streaked with chestnut- 

 rufous. Ad. in winter and Im. Crown-cap partly concealed by the brownish tips to the feathers, 

 or sometimes wanting; line over the eye and eye-ring yellowish; entire underparts uniform yellow, 

 washed with ashy; the sides of the throat, the breast, and sides streaked with chestnut-rufous 

 or dusky. L., 5.43; W., 2.61; T., 2.10; B. from X., .31.
