FAMILY Mnaiotiltide. 
Warbler that it is difficult to tell where the difference 
lies; but a certain hesitancy near the end of the Chest- 
nut-sided’s song usually betrays its author. Here again 
is another variation which shows that the bird had 
revised almost the whole structure of the typical song, 
and, regardless of the whole tribe of Warblers with all 
their musical traditions, had decided like the wilful 
Scotchman to ‘‘ gang his ain gait”: 
2 i SI 
I might say now, with Mr. Cheney, ‘‘ match that if you 
can!” | 
The voice of the Chestnut-sided Warbler is only mod. 
erately clear, and is therefore far less penetrating than 
that of the Yellow Warbler. Such a tone, too, implied 
by the syllable chew or cher, reveals a quality sus- 
piciously near the overtone. But, as a matter of fact, 
there is no real overtone present in any of the bird’s 
votes. In a great number of the songs there are only 
six syllables, but these do not otherwise differ from the 
common type as I have represented it here. Miss Ethel 
Dame Roberts’s ‘‘ tsee, tsee, tsee, Happy to meet you!” 
is analogous to another popular saying of the bird, I 
vish, I wish, to see Miss Beecher! If there is any one 
who can whistle that lady’s name better than the Chest- 
nut-sided Warbler he must be a ventriloquist of excep- 
tional ability! 
Bay-breasted This Warbler is a rather uncommon bird 
ada seen only during its passage to and from 
endroica ; y i % 
PG non its home in the extensive coniferous for- 
L.5.70inches estsof Canada. The year of the great mi- 
May 2oth gration, 1899, probably saw more of this 
species in unexpected places than any records will ever 
show. The bird is beautifully marked, in colors not un- 
like those of the Orchard Oriole. Crown, and entire 
throat, breast, and sides rich burnt sienna or chestnut.
