 Dendroica PALMARUM HYPOCHRYSEA.

 back; crown chestnut; line over eye and under parts rich yellow; breast 

 and sides streaked with brown ; no white wing bars ; square patches of 

 white on outer tail-feathers. Adult in winter and young ; similar but 

 colors duller, and markings less distinct; underparts grayish yellow. 

 Length 5 to $^ inches. 



A^esi. On the ground on border of swamp; loosely made of grass, 

 weeds, and moss fastened with caterpillar's silk, lined with roots, hair, 

 pine-needles, or feathers.

 larger end with fine spots of brown and lilac ; 0.65 X 0.50. 



The Yellow Red-polls in small numbers arrive in the Middle 

 and Northern States in the month of April; many proceed as 

 far as Labrador, where they were seen in summer by Audubon, 

 and in the month of August the young were generally fledged. 

 In the Southern States they are abundant in winter. While 

 here, like many other transient passengers of the family, they 

 appear extremely busy in quest of their restless insect prey. 

 They frequent low, swampy thickets, are rare, and their few 

 feeble notes are said scarcely to deserve the name of a song. 

 These stragglers remain all summer in Pennsylvania, but the 

 nest is unknown. They depart in September or early in Octo- 

 ber, and some probably winter in the southernmost States, as 

 they were met with in February, by Wilson, near Savannah. 

 This is a different species from the Palm Warbler, which prob- 

 ably does not exist in the United States. 



This bird appears yet to be very little known. Pennant has 

 most strangely blended up its description with that of the 

 Ruby-crowned Wren ! his supposed female being precisely 

 that bird. 



The Eastern form of the Palm Warbler is a common bird from 

 the Atlantic to the Mississippi valley, where it is replaced by true 

 palma7um, and is abundant in summer in northern Maine and 

 New Brunswick.
