BLACK-CHEEKED FALCON. 
dashing straight towards me and then sheering ofi when within a few yards. 
From time to time they perched on points of rock and sat watching me and 
occasionally would sail along the cliffs like a swallow. Last autumn and 
winter the birds were flying about Circular Head, and were generally 
observed returning to these cliffs in the evening very high in the air, 
and announcing their presence by screams, which are like the noise a 
slate pencil makes on a slate, or a railway carriage* wheel tightly braked 
dragging along a rail. At times I have seen them flying in an aimless 
manner at a great height from the ground, like a hawking Swallow. They 
dip during the last few yards of flight, and sail gently upwards just before 
they alight. On the 16th September, 1887, 1 found the Black-cheeked Falcons 
nesting in the same place on Circular Head Bluff as the previous year. 
I saw one bird twice fly screaming to the crevice, where he was received 
with chuckling screeches, and immediately sail out again. I believe the 
male was feeding his incubating mate, but could not see if he carried any 
prey in his claws as he flew in. I saw two of these birds mobbing a 
White-beUied Sea-Eagle on the sandhills between East Inlet and the sea. I 
took two incubated eggs on the 4th October, 1888, from a nesting-place in the 
cliffs near the coast. The two birds kept flying at my face and uttering loud 
screams as I sat by the eggs, flrst from one side and then the other, making 
short circuits in the air and then dashing down. They came very close, not 
arm’s length but hand’s breadth of me, though I struck repeatedly at them. 
They even followed me when I retreated among the Banksia trees close at 
hand and sat down to pack the eggs. Compared with Circular Head Bluff 
these rocks, where this pair bred, which were only about sixty feet high, 
scarcely deserved the name of cliffs at all. On the 26th September, 1891, I 
took a set of three incubated eggs from the same nesting-place, but the birds 
were not at hand, although I saw one swooping a long way off. In September, 
1893, the pair of birds at Circular Head Bluff nested again in the same 
inaccessible spot.” 
It will be gathered from Gould’s observations that the Peregrine is\iEound 
all over the world in various forms, and how close the Australian is to the 
European appears in Vigors and Horsfield’s observation that they could not 
distinguish the solitary specimen from Australia from European birds. 
Hartert, on his own saying, the most fitted to judge the Falcons, has 
contributed some Notes on Falcons to the Nov. ZooL, Vol. XXII., pp. 167-185, 
June, 1915. His results are expressed thus ;
