671, Dendroica vigorsii (AUD) [m.] 



Pine Warbler. 



Hab. Eastern United States, north to Ontario and New Brunswick; wintering in more Southern 

 States and Bahamas; Bermudas. 



The Pine-creeping Warbler breeds in various localities through- 

 out its United States range and apparently only in regions where 

 there are tracts of coniferous trees. Its nest is always placed on the 

 horizontal boughs in pines or cedars, ranging all the way from eight 

 to eighty feet above the ground, usually at an elevation of from thirty 

 to forty feet. In the pine districts of the States along the Atlantic 

 coast from the Carolinas northward the bird is a common breeder, 

 nesting in March. Mr. R. B. McLaughlin took nests containing eggs 

 in Iredell county, North Carolina, March 25. Mr. C. S. Brimley 

 found the birds building nests in Wake county, of the same State, in 

 the latter part of March. The nest, according to these observers, is 

 hard to discover, and in most cases it is found by watching the birds 

 carry building material, which consists of bark-strips, bits of weed and 

 oak leaves, caterpillar's silk, and vegetable sedges. It is compactly 

 built and warmly lined with horse hair and feathers. The eggs are 

 four, rarely five in number. Nineteen sets of the eggs of this Warbler 

 are in Mr. Norris' cabinet, eighteen of which have a ground-color that 

 varies from a dull whitish to gray or purplish-white, and the markings 

 are in the form of spots and specks of lilac-gray and burnt umber, 

 more dense near the larger ends, and generally form wreaths. The 

 nineteenth set seems to be of a very rare phase, being pinkish-white 

 with brick-red markings. Two sets give the following respective 

 measurements: .69X.53, .66x.5i, .67x.5i, .69x.5i; -75X.55, .75 x 

 55) -7 1 x -55) -76 x .55. The average size is .70 x .52. 



Dendroica palmarum hypochrysea RIDGW. [113*.] 



Yellow Palm Warbler. 



Hab. Atlantic coast of North America. Breeds from New Brunswick and Nova Scotia to Hudson 

 Bay. Winters in the South Atlantic and Gulf States. 



There are two forms of the Palm Warbler, D. palmarum (Gmel.) 

 being the form of the interior region north in summer to Great Slave 

 Lake, migrating south through the Mississippi Valley to the Gulf 

 States, Florida, Bahamas, etc., and casually during migrations east of 

 the Alleghanies. The present form, hypochrysea, breeds from Nova 

 Scotia and New Brunswick northward. Its nest is placed on the 

 ground in open situations, usually on the edge of a swampy thicket
