I have little to say of this changeable species. It occurs but sparsely with us, coming rather late in the autumn, when the plumage is undergoing its transformation, so well detailed by Wilson. On only one occasion have I observed them numerous; towards the latter part of March, on the estate called Dawkins’ Saltpond, near Spanish town, many were hopping about the Cashaw trees (Prosopis juliflora) that abound there. All of these that I examined, had the yellow of the crown obscured, and some almost obliterated. One which I shot in October did not display it at all, while one in January had the hue very brilliant, but only at the bases of the coronal feathers; exposed or concealed as in some of the Tyrants. As far as I have observed, the manners of this bird are those of a Flycatcher, capturing minute insects on the wing, and returning to a twig to eat them. The stomach is usually filled with a black mass of minute flies.

Sylvicola pensilis.

Wilson has justly observed that the habits of this lovely bird are those of a Tit or a Creeper. I have usually observed it creeping about the twigs of trees, or among the blossoms. The first I met with was thus engaged, creeping in and out, and clinging to the beautiful and fragrant flowers that grew in profuse spikes from the summit of a papaw-tree. It is one of the earliest of our visitors from the north, for this was on the 16th of August; and it remains until April among the sunny glades of our magnificent island. The stomach of such as I have examined was large, and contained caterpillars of various sizes and species. An individual in March, which I proved by dissection to be a female, did not differ in intensity of colouring, or any other appreciable respect, from the male. The eggs in the ovary at that season, were distinguishable, but minute.
