An early warbler to arrive in spring and the last one to depart in 
autumn. At times in the latter season the brushy wastes, roadsides, and 
the overgrown fence lines are filled with Myrtle Warblers each showing, as 
it darts away, its distinct yellow rump as proof of its identity. 
657. Magnolia Warbler. BLACK AND YELLOW WARBLER. FR.—LA FAUVETTE A 
TBTE CENDREE. Dendroica magnolia. L, 5-12. Plate XLI B. 
Distinctions. ‘The bright yellow breast and underparts sharply striped with black, 
black cheeks, and greyish upperparts are perfectly distinctive in the spring. Autumn 
birds have recognizable reflections of the adult plumage but the breast markings are absent 
and those of flanks reduced. The head and cheeks are evenly greyish and the back greyish 
shaded with green to the rump which is suffused with yellow. 
Field Marks. The yellow below and on rump will separate the Magnolia from all 
warblers but the Cape May. The latter’s yellow breast is sharply and more evenly 
striped with black and it has the chestnut ear patch. Close examination of the Magnolia 
in autumn plumage always shows a vague, light ashy bar across the upper breast. 
The tail is also a good identification mark. The characteristic white marking of the 
tails is well back from the tip and rather extensive, giving, when seen from below, the 
appearance of a white tail broadly banded with black. 
Nesting. In coniferous trees 3 to 6 feet from the ground in nest of fine twigs and 
leaf stems lined with hairlike rootlets. 
Distribution. Eastern North America north to tree limits; breeds mostly north of 
general cultivation. 
One of the most beautiful of the warblers, on migration coming into 
shade trees and orchards where its rich coloration makes a pleasing com- 
bination with the blossoms. 
658. Cerulean Warbler. Dendroica cerulea. IL, 4-50. Male: sky-blue and white. 
Above, all blue with fine black markings on back and sides of crown. Below, pure white 
with blue breast-band and flank stripes;wing-bars white. Female: even dull greenish- 
blue above, white below, more or less stained with greenish and yellow suggestions. 
Juvenile similar but yellower all over. 
Distinctions. The male is unmistakable. Other plumages have a peculiar bluish, 
instead of olive or yellowish, green above that is quite characteristic. The Juvenile with 
its yellowish-greenish underparts is somewhat similar to the young Tennessee, having 
a similar eyebrow stripe, but its white wing-bars and tail patches will separate it. 
Field Marks. The blue of the adult and the bluish sheen of other plumages. Other- 
wise like a juvenile Tennessee but with wing-bars and white in tail. 
Nesting. In a tree 20 to 60 feet above the ground in nest of fine fibres bound with 
spider’s web, lined with strips of bark fibres and with a few lichens on the outer surface. 
Distribution. Eastern United States except the coast; north along lake Erie to 
just within Canadian territory. 
Too rare in Canada to be expected regularly except in a limited area 
in southern Ontario. 
659. Chestnut-sided Warbler. ¥FR.—LA FAUVETTE DE PENSYLVANIE. Dendroica 
pensylvanica. L, 5:14. Male: Crown yellow; back black and grey in stripes, over- 
washed with yellowish green; below white with chestnut bands along flanks; two white 
or yellowish wing-bars. Juvenile: an almost even yellowish-green above, white below, 
cheeks grey; usually with suggestions of the chestnut sides of the male. 
Distinctions. Superficial attention to the above description might confuse this 
species with the Bay-breasted but the white throat is distinctive. Spring birds with 
their yellow cap, chestnut sides, and white underparts; and autumn birds white below, 
yellowish green above, and yellowish wing-bars are easily recognized. 
Field Marks. The white underparts and peculiar lemon yellowness of the green above 
ae good recognition marks even in plumages where the characteristic markings do not 
show. 
Nesting. In bushes some 3 feet from the ground in nest of strips of bark, leaf stems, 
etc., lined with tendrils and rootlets.
