Bush Kingfisher, Residents at Port Essington. 
There certainly has not yet been discovered a more beautiful Halcyon in any part of the world than the one 
figured in the accompanying Plate, which has been dedicated to Mr. Alexander MacLeay by the authors of 
the " Illustrations of Ornithology " as a tribute of respect, in the propriety of which I entirely concur. 
The extreme brilliancy of the plumage of this bird would seem to indicate that it is an inhabitant of a 
hotter climate than that of New South Wales, and the correctness of this inference is borne out by the 
fact that the Halcyon MacLeayii has only yet been found on the extreme northern portion of the continent ; 
it is tolerably abundant at Port Essington, and it is also spread over every part of the Cobourg Peninsula 
suited to its peculiar habits ; like the other members of the genus to which it belongs, it is rarely if ever 
seen near water, and evinces so decided a preference for the open forests of the interior of the country that 
it has obtained the name of "Bush Kingfisher" from the residents at Port Essington ; it is generally di- 
spersed about in pairs, and feeds on small reptiles, insects and their larva? ; its general note is a loud pee-pee 
uttered with considerable rapidity. It incubates in November and December, sometimes forming its nest 
in the hollow trunks of trees, and at others excavating a hole for itself in the nest of the tree-ants, which 
presents so prominent and singular a feature in the scenery of the country : the nest of the H. Macleayii is 
easily discovered, for on the approach of an intruder the birds immediately commence flying about in a 
very wild manner, uttering at the same time a loud piercing cry of alarm ; the eggs are three or four in 
number, of a pearly white and nearly round in form, being eleven lines long by ten broad. 
So much difference exists in the plumage of the sexes that Mr. Gilbert states he was for some time in- 
duced to regard them as specifically distinct ; an error into which I had myself previously fallen when de- 
scribing the female as a new species in the " Proceedings of the Zoological Society" as quoted above ; " but 
upon closer observation," adds Mr. Gilbert, " I soon satisfied myself that the difference of plumage was 
merely sexual, the dissection of a large number of specimens fully proving that those with a ring round the 
neck are males and those without it females." 
The male has a line under the eye and ear-coverts deep glossy black ; head, occiput, wings and tail rich 
deep prussian blue ; primaries and secondaries white at the base, forming a conspicuous spot when the wings 
are spread ; for the remainder of their length these feathers are black, margined externally with light 
prussian blue ; immediately before the eye an oval spot of white ; collar surrounding the back of the neck 
and all the under surface white, tinged with buff on the -lower part of the flanks ; back and upper tail- 
coverts verditer blue ; scapularies verditer green, both these colours bounded near the white collar with 
prussian blue ; under surface of the wing white, the tips of the coverts black ; under surface of the tail 
black ; bill black, the basal portion of the under mandible yellowish white ; tarsi black ; inner side of the 
feet and back of the tarsi ash-grey ; irides very dark brown. 
The general colours of the female are similar to those of the male, but she differs from her mate in being 
entirely destitute of the white collar at the back of the neck, which part is deep prussian blue, thus uniting 
the blue of the occiput and of the back ; in the tints being much less brilliant in the back, being of a dull 
brownish verditer green, and in the upper tail-coverts pale verditer green instead of blue ; upper mandible 
black ; lower mandible half-way from the tip and along the whole of the cutting edges black, the remainder 
being fleshy white tinged with blue where it joins the black ; legs and feet greenish grey. 
The young male resembles the female in colour, but is still less brilliant ; has the back of a purer green ; 
the under surface tinged with buff ; the spot on the lores deep buff ; and the collar at the back of a deep 
buff, interrupted by some of the feathers of the occiput. 
The figures are those of a male and a female of the natural size.
