(70.)Dendrcecaooronata {Linn.) Gray. Yellow-rumped Warbler. A n-inter resident; extremely abundant, especially during the springmigrations, when the numbers which pass the. winter are recruited byarrivals from the South, before all go off together.

Theprocess seems to be protracted during the whole of that month, whenmost individuals shot are found to be in patchy garb; spick-span speci-mens, however, are to be caught early in May, just before they are most numerous in April and October, least so in the depth ofwinter. They are to be found everywhere, but are fondest of hedges,copses, orchards, and cedar thickets, which they haunt in troops, accom-panied by titmice and sparrows.
