“The combination of circumstances that make up a fit nestling place for it, may be well understood from the following selection of a burrow, by a pair of birds, in the garden of a friend. A box filled with earth had been placed on tressels within water, for growing lettuces from seed, or rather for saving the seed, whilst vegetating, from the depredations of ants. The box had performed its office;—the lettuces had been transplanted, and the mould remained in undisturbed fallow. The box having a knot-hole in the side, through this hole a pair of Todies burrowed a gallery into the heart of the mould, built a nest, and reared a family of young ones. They were assiduous sitters, the male and female relieving each other. Though they attracted a good deal of attention, and were not unfrequently disturbed by the curiosity of visitors, they steadfastly pursued their family affairs, and showed surprising vigilance and caution in escaping out of their cavern, when they were either watched, or attempts were made to catch them. They never failed to profit by the moment when attention was withdrawn from them, either to come from out of their cave, or to dart into it. On opening the earth after the young had fled, there was found a capacious winding gallery into the centre of the box, ending in a circular lodging, in which was contained the nest, composed of fibrous roots and cotton. “There is such an obvious similarity between the Kingfisher and the Tody, particularly the brilliant blue and green European Kingfisher, that few who are acquainted with both fail to recognise their affinity. The brilliant plumage of the two birds; the patient watchfulness with which they both sit on some exposed twig to await the vagrant prey; their short flight from station to station; and their repeated return to the same spot;—independent of that intimate resemblance in the structure of their extremities, which led Brisson, Latreille, and Cuvier, to arrange the Halcyons in company with the Todies, would induce one to conclude that there was some propinquity in their natures, without any great knowledge of Natural History. The difference of the element in which they severally seek their food, does not widen the affinity between them, for the Jacamars of America, and the Martin-chasseurs of Africa, or King-hunters, as they are called, to distinguish them, in their pursuit of a terrestrial or aërial prey, from the Kingfishers or Martin-pecheurs, which seek theirs only in the water,—are placed in no less near a relationship of habits and structure. The similarity is remarkably increased, when we go on to the habit of burrowing, which prevails alike among all these birds, and to the syndactyle form of the feet. These resemblances remove all doubt about their classification.
