Specific Character.
S. cæruleo-grisea, infra aurea; dorso olivaceo; tectricium apicibus albis.
Blue grey, beneath golden yellow; back olive; wing-covers tipt with white.
There is an elegance of shape, and a harmony of colouring, in the Warblers, that render these delicate little birds very interesting. The species are exceedingly numerous, and are spread over most parts of the world; several abound in our own woods and hedges, and the "sacred bird" of our childhood, the Robin Redbreast, is among the number. That now before us is a native of Brazil, from whence it was received by Mr. Leadbeater; I never met with it myself. The first quill feather is hardly shorter than the three next, which are all of equal length; the tail-feathers are even, and rather pointed; their colour black, margined with grey; the two outer with a white spot on the inner web; the under wing and tail-covers white.
I have made no material alteration in Prof. Temminck's definition of this overgrown genus, being convinced it might lead to confusion, while the generality of the birds composing it remain so little known.
This bird greatly resembles the female of S. pusilla of Wilson (yellow-backed Warbler, Latham), yet differs in having the belly golden yellow instead of white: I was told, moreover, that this was a male bird: the one inhabits North, and the other South America. Latham's description of his yellow-backed Warbler, I should think, is not quite accurate; as he only alludes to one white bar on the wing covers, whereas both Wilson and Vieillot say there are two.
