Redstart
the Ruticilla phœnicura; migrating S. in the winter. Forehead in Europe and western Asia, pure white, throat black, upper surface dark gray; breast, sides, and tail bright rust-red. It nests usually in a hollow tree or in a hole in a wall or rock, and lays five to seven delicate greenish-blue eggs, sprinkled with faint spots of red.
The black, or black-capped redstart, R. titys (or titis) is common on the Continent, but has not the extended N. range of the common redstart. In the United REDUCTIO AD ABSURDUM States the name is given to Setophaga ruticilla, a fly-catching warbler. Male, black with patches of orange-red. Female, olive with yellow patches.
