The Great Brown Kingfisher does not inhabit Van Diemen’s Land, nor has it yet been met with in Western Australia; it may be said to be almost solely confined to that portion of Australia lying between Spencer’s Gulf and Moreton Bay, the south-eastern corner, as it were, of the continent. The plate in the Pl. Enl., quoted above, has been considered by all previous writers to have reference to this bird, and while I coincide in this opinion, I think that some mistake must have arisen as to the locality, and that it never visits New Guinea nor even the northern coast of Australia, where its place is supplied by the _Dacelo cervina_ and _D. Leachii_. Unlike most other species, it frequents every variety of situation; the luxuriant brushes stretching along the coast, the more thinly-timbered forest, the belts of trees studding the parched plains and the brushes of the higher ranges being alike favoured with its presence; over all these localities it is rather thinly dispersed being nowhere very numerous. I believe that this bird seldom, if ever, drinks; consequently the most arid plains are as suitable to its habits as the shrouded river sides and the flat brushes near the coast. Its food, which is of a mixed character, consists exclusively of animal substances; reptiles, insects and crabs, however, appear to be its favourite diet, upon which it is destined by nature to subsist: it devours lizards with avidity, and it is not an unfrequent sight to see it bearing off a snake in its bill to be eaten at leisure; it also preys on small mammalia. I recollect shooting a Great Brown Kingfisher in South Australia in order to secure a fine rat I saw hanging from its bill, and which proved to be a rare species inhabiting the plains of that part of the country. It breeds during the months of August and September, and generally selects a hole in a large gum-tree for the purpose; making no nest, but depositing its beautiful pearl-white eggs, which are one inch and nine lines long by one inch and five lines broad, on the decomposed wood at the bottom of the hole. When there are young ones in it, it defends its breeding-place with great courage and daring, darting down upon any intruder who may attempt to ascend the tree, and inflicting severe and dangerous blows with its pointed bill. The sexes present so little difference in the colouring of their plumage, that they are scarcely distinguishable from each other; neither do the young at a month old exhibit any great variation from the adult, the only difference being that the markings are somewhat darker and the brown more generally diffused.
