“Kind reader, you are now presented with a new and beautiful little species of Warbler, which I have honoured with the name of a family that must ever be dear to me.  Were I at liberty here to express the gratitude which swells my heart, when the remembrance of all the unmerited kindness and unlooked-for friendship which I have received from the Rathbones of Liverpool comes to my mind, I might produce a volume of thanks . . .

I met with the species now under consideration only once, when I procured both the male and the female represented in the plate.  They were actively engaged in searching for food amongst the blossoms and leaves of the Bignonia on which I have placed them.  All my endeavors to discover their nest, or to procure other individuals, having proved abortive, I am unable to say anything of their habits and history; but should I be more fortunate at some future period, I shall not fail to record the result of my observations respecting this delicate little Warbler.”
