PARULA AMERICANA PUSILLA (Wilson)
NORTHERN PARULA WARBLER
HABITS
I have always preferred the old name, blue yellow-backed warbler, as originally used by Wilson and Audubon, to the modern common name; it seems more descriptive of this dainty wood warbler. As to the origin of this newer name, Dr. Spencer Trotter (1909) writes: “The name ‘parula’ recently in vogue for the warblers of the genus Compsothlypis is clearly borrowed from the old Bonaparte genus Parula (diminutive of titmouse). The bird (C. americana) has appeared under various titles—‘the Finch Creeper’ of Catesby (I, 64), ‘the various coloured little finch creeper’ of Bartram (Travels, 292), and the ‘Blue Yellow-backed Warbler’ of Wilson, Audubon, and later authors.” Parula was extensively used as the generic name during the last century, and is now reinstated to replace Compsothlypis.
