Summer Bds.Mt. Mansfield, Vt'. 
70. Wilsonia canadensis. Canadian Warbler. — Common in the 
thickets in the deciduous woods, ranging nearly throughout the Canadian 
zone. Although they keep well concealed in the shrubbery and do not 
move about much, their odd song, uttered at frequent intervals, serves to 
indicate their presence.
