It is in the months of May, June, and July, that this Creeper performs the business of incubation. On the 4th of May, as I was riding to Savanna le Mar, I observed a Banana Quit with a bit of silk-cotton in her beak; and on searching, found a nest just commenced in a sage-bush (_Lantana camara_). The structure, though but a skeleton, was evidently about to be a dome, and _so far_, was constructed of silk-cotton. Since then I have seen several completed nests. One now before me, is in the form of a globe, with a small opening below the side. The walls are very thick, composed of dry grass, intermixed irregularly with the down of _Asclepias_. It appeared to have been forsaken, from my having paid it too much attention. It was fixed between the twigs of a branch of a _Bauhinia_, that projected over the high road, near Content, in St. Elizabeths. Another which I found at the end of June, in a sage-bush, was of the same structure; in this were two eggs, greenish-white, thickly but indefinitely dashed with reddish, at the larger end. Robinson states the dimensions thus:—“the length about 3¹⁄₂ eighths, the diameter about 2¹⁄₂ eighths,” but I find my specimens much larger than this: accurate measurement giving ⁵⁄₈ inch by rather less than ¹⁄₂ inch. An exceedingly interesting memoir, from the pen of Mr. Hill, on the prevalence of domed nests within the tropics, and the connexion of this fact with electricity, will be found in the Zoological Transactions for September 14th, 1841.
