Haliastur sphenitrits (Whistling Eagle).—Before I eradicated the rabbits on the Estate these birds were present in great numbers, and I used to take about thirty clutches of their eggs every year. As soon as I got rid of the rabbits these Eagles mostly disappeared, and now I only see on an average about one nest a year. They are very erratic in their breeding habits ; I have taken their eggs during every month of the year with the exception of January and February. Two eggs are usually the full clutch ; but of one hundred and eight nests I have examined containing eggs, thirteen contained sets of three. I have never seen a larger clutch, and only once have I seen three young birds in a nest. Falco htiiiifatus (Little Falcon).—A very rare species here, just occasionally a pair or a single bird putting in an appearance at any time of the year. I have only known them to breed here once ; the nest was placed near the top of a very lofty river redgum tree, from which I scooped three fresh eggs on October 9th, 1912. Hieracidea orientalis (Brown Hawk).—During the years 1908, 1909, 1910 and 1912 these birds were very common here, and I took seventeen sets of their eggs. Since then I have not known them to breed here till 1917, when I found two nests ; in fact, the birds arc seldom seen here now. They generally use an old Raven's nest ; only once have I known them to build a nest for themselves. The clutch is generally three ; I have never taken more. 1 have examined nests containing eggs from the middle of August till November nth. They do no harm. 1 have not even known them to kill a bird of another species. Cerchneis cenchroides (Kestrel).—Frequently met with at any time of the year. They are quite harmless ; in fact, I consider
