CHESTNUT-SIDED WARBLER. 
ers that the song nearly always ends with a falling 
inflection of the voice. Mr. White records a falsetto 
warble, purr-a-e whu-a which I have never heard. 
The Magnolia’s summer home is among the evergreen- 
trees, and he may easily be found among the firs and 
hemlocks of old overgrown pastures, ever on the move; 
and seldém flying higher than the top of one’s head. 
The species is a regular summer resident in parts of the 
White Mountains. ; 
Chestnut-sided This handsome little bird is one of our 
Warbler commonest Warblers, and next to the

pensylvanica Yellow Warbler the most familiar and in- 
L.5.10 inches teresting one though he is by no means as

is quickly identified by his costume. Top of head bright 
yellow bordered on the sides with black; a band of black, 
beginning between the eye and the bill, extends down-

the throat, and under parts are white; sides burnt sienna 
or chestnut; back of the neck streaked with black and 
gray; lower back black striped with greenish yellow; 
wings with two yellow-white bars; tail black with the 
inner vanes of the outer feathers white-patched near the 
tip. Female similar in markings but duller in color.

it winters in Central America. Its chosen haunts are the 
overgrown pasture where bushes are plenty, bushy road-

The Chestnut-sided Warbler has several forms of song,

notation of which I have marked No. 2. But a careful 
comparison of these songs will show that there is no
