YELLOW PALM WARBLER. 219 
YELLOW PALM WARBLER. 
YELLOW RED-POLL WARBLER. 
DENDROICA PALMARUM HYPOCHRYSEA. 
Cuar. Above, brownish olive; rump yellowish, dusky streaks on the 
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 two pairs of outer tail-teathers. Length 5 to 534 inches. 
Vest. 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. 
Eggs. 4-5; creamy white, sometimes with roseate tinge, marked on 
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 
palmarum. The Eastern bird is abundant in summer in northern 
Maine and New Brunswick, and Aububon considered it common 
in Labrador, though late observers there have rarely found it.
