Milvus Affinis
9. MILVUS AFFINIS, GOULD.--Allied Kite.
This bird is common over the whole continent of Australia. They are sure to be in numbers at the camps of the natives, which they frequent to pick up what may be left when they go away. They are sure also to follow any party in the bush for the same purpose. About fifty of these birds remained at the Depot, with about as many crows, when all the other birds had deserted us; and afforded great amusement to the men, who used to throw up pieces of meat for them to catch in falling. But although so tame that they would come round the tents on hearing a whistle, they would not eat any thing in captivity, and would have died if they had not been set at liberty again. It was this bird which descended upon Mr. Browne and myself in such numbers from the upper regions of the air, as we were riding on some extensive plains near the Depot in the heat of summer. There can be no doubt but that in the most elevated positions where they are far out of the range of human sight, they mark what is passing on the plains below them. This bird is figured, see page 269, Vol. 1.
10. ELANUS SCRIPTUS, GOULD.--The Letter-winged Kite.
This beautiful bird was first seen on a creek to the eastward of the Barrier or Stanley's Range, and before the party had crossed that chain of hills. One was shot on the advance of the Expedition from the Darling in the early part of November 1844, in latitude 32 degrees, and on the return of the party from the interior, in December 1845, several specimens were seen as low as Cawndilla, and ranging along the banks of the Darling. In the interval they were seen in flocks of from thirty to forty, either soaring in the air or congregated together in trees. They were never seen to stoop at any thing, nor could we detect on what they fed, but I am led to believe that it was mice. They are fond of hovering in the air, and in such a position look beautiful, the black bar across the wing underneath them appearing like a W, and contrasting strongly with the otherwise delicate plumage of the bird. They left us for a time whilst we remained at the Depot, and the first that were afterwards seen by us were on the return of Mr. Browne and myself from our first northern journey.
These birds are widely distributed over that part of the interior traversed by the Expedition. Like Elanus notatus, it has a bright full eye, the iris inclined to a light pink. Its shoulders are black, and its back like a sea-gull, slate-coloured.
11. CIRCUS JARDINII, GOULD.--Jardine's Harrier.
This bird, with its spotted plumage, was not common. A specimen was shot on the banks of the Darling, between Williorara and the junction with the Murray. None of the same bird were seen in the N.W. interior, or to the westward of the Barrier Range.
12. STRIX PERSONATA, VIG.--Masked Barn Owl.
This fine night bird was very rare in the interior, and only one specimen was procured. Its plumage is characterised by that softness so peculiar to the genus to which it belongs, and in consequence of which its flight is so silent and stealthy that, like the foot-fall of the cat, it is unheard.
